Using a drum carder – part 2, carding raw fleece

This post will explain one method I use to card raw fleece on a drum carder. The basics of using a drum carder are explained in this post, and future posts will cover blending of fibres and cleaning of the carder.

The method outlined below is time consuming, preparing the fleece before carding is a lengthy process, and the amount of pre-preparation needed depends on the state of the fleece, and the desired end result. This is not the fastest way of doing this, but it’s the only way I’ve found that works with fleeces with dirty tips or lots of VM.

First, your fleece needs to be clean. Using a drum carder with unwashed fleece will get your carder very dirty and covered in gunge that will be hard to remove and will contaminate future batts. It may also damage your carder. A fleece washing tutorial will follow, but there are plenty of others already out there online.

The fleece I am carding in the below images is a cormo fleece.  It was a coated fleece so there isn’t much VM, but some of the tips were caked with mud, and I didn’t want this mud to get into the batts. In the below pic you can see a lock of the fleece, with its dirty tips, and also a few nepps at the butt end (which are a common feature of lots of raw fleeces). [clicking on any of the pics will take you to a larger version in my flickr account].

I don’t want any of the bits of mud, or the nepps, in my final batt. It’s very difficult to get a completely nepp-free batt, especially with a wool as fine as cormo, but the method shown helps get out as many of them as possible before carding. To remove the dirt and nepps (and any VM), grab the lock about half way down the staple, and run it over a hand carder laid flat on your lap. You can see that the bits are gone, the wool is fluffed up, and there’s a few lumps left behind on the carder. If the fleece had VM in, most of this would also be trapped by the teeth of the carder.

cormo2

Turn the lock around, and repeat the process to detangle and remove any nepps from the bottom end. Repeat this process for as long as your patience will allow, or until you have enough fibre to make a batt.

Place your opened up locks of fibre on the feed tray of the carder. Don’t overfill the tray, you should be able to see the tray through the fibre.

cormo3

Slowly turn the handle of the carder with one hand, while using the other to gently guide the fibre towards the licker in drum. Don’t pull on the fibre, just hold it in place while the carder pulls it in. The fibre will wrap around the large drum in thin layers. If you’re using a fine fibre like I am, you will probably find it doesn’t want to sink to the bottom of the teeth, and there will be patches of wool close to the top of the teeth like this.

cormo4

If there are any noticeable lumps or bits of unwanted fibre/VM close to the top of the teeth, pull them out now, then use a hairbrush or similar to push the fibres down while turning the drum.

Add more fibre to the feed tray, and repeat this process several times, until the carder starts to fill up. You may find that some fibre wants to fall off the edge of the carder like in the below image. For the first pass on a raw fleece, I ignore this, provided it doesn’t start to get near the axel or moving parts of the carder. If it does start to go to places it’s not wanted, pull the fibre up and either place it on the edge of the drum, or pull it off and put it back in the feed tray, and in future try to feed the fibre a cm or away from the edge of the tray to stop it happenening again.

Once you’ve run out of fibre, or when the drum is starting to get full, you need to remove the batt. Use your doffing tool (mine is called a ‘knuckle saving batt pick’) and came with the carder…a knitting needle can be used too, but watch your hands on the teeth. At the break in the card cloth, use the tool to free a small section of fibre at a time, you shouldn’t have to pull hard, if you do, you’re trying to do too much at once.

cormo6

Once you’ve severed all the fibres, run your tool along the gap to make sure there are no more small areas of fibre joined together, then you’re ready to remove the batt. Roll the batt off the carder (some people suggest to roll it around a rod, I’ve never found this to be necessary), keeping your hands as close to the carder as possible to pick up as many stray fibres as you can. You’ll see the drum is almost completely clean, the few straggly fibres which are still attached will be picked up as you roll. On the first pass, there may be a few fibres which aren’t joined to the rest of the batt that want to stay deep in the teeth…remove these after the batt is taken off by running your flick carder over the drum.

cormo7

When your batt is off the carder, hold it up to the light and have a look at it. You’ll see the wool isn’t even at all, there are clumps, and areas where the fibres don’t run parallel…and you’ll also see in my batt, despite my best efforts, there are a few nepps. I am fairly sure these were always in the fleece and weren’t caused by me trying to card too much at once, or being too rough, though with a very fine fibre, you will start to add nepps however careful you are.

cormo8

Take your batt, and tear it into strips lengthways. Each of these strips will be fed through the carder again. In the photo, the strip on the left is small enough to be recarded alone, the others were split in half again before carding.

cormo9

Take one of your strips and spread it out flat between your hands, so its about the same width as the feed tray, then recard it, the same as before, turning the handle slowly, and using your hand to guide in the fibre.

cormo10

Repeat this with the rest of the batt, then again remove the batt and hold it up to the light. You’ll be able to see the batt is more even, with fewer fibres travelling in the wrong directions.

cormo11

Tear this batt into strips, and repeat, until you are happy that your fibre is carded enough. I did one more pass, making 3 in total, and I may do another one, but I don’t want to add more nepps.

My batt after 3 passes is looking a lot more even.

cormo12

And that’s it…your batt is ready to spin!

A note on different methods.

If your fleece doesn’t have dirt, lumps, or VM in, you don’t need to comb the locks before carding unless the fleece is matted together. If the fleece is light and airy, you can just grab a chunk of it, and pull apart with your hands to separate the fibres. You will end up with a light and airy cloud of fibres, which can be fed into the carder in the same way as above. As the fibres will not all be parallel in this cloud, you’ll need to do several more passes to get it smoothly carded, I find normally around 6 passes gives me a lovely even airy batt.

If your fleece is clean but a bit neppy at the butt end, you may decide you don’t want to remove the nepps, to give yourself a textured yarn. Again in this case you don’t need to spend time combing them out, just fluff up the fibres and card, and the nepps will be incorporated into your batt.

Thanks for reading…any comments are welcome, and questions will be answered in future posts.

Using a drum carder – part 1, the basics

I was asked to write a tutorial on how to use a drum carder. This is a huge topic, so in this first post I will go over the basics. Future posts will cover carding raw fleece, and blending commercially prepped fibres, as well as how to clean your carder.

First, the basics. What is a drum carder?

A drum carder is a machine which is used to prepare fibre for spinning. It has two drums, one small one (sometimes called a licker-in) which helps guide in the fibre, and then a large one, which the fibre ends up wrapped around. When the larger drum is full, the fibre is removed, and the resulting chunk of smooth fibre is called a batt. There are several ways to spin from batts, and I will cover those in future tutorials.

There are several different makes of drum carder, I have a Strauch carder, which can be seen here. I chose the Stauch because it has finer card cloth than the others available, meaning it can be used for carding finer fibres, because the licker in cloth is of a unique design that doesn’t trap the fibre, and because it is chain rather than belt driven, meaning it will hopefully last as long as I do.

My carder (pre-cleaning as I took the pic to use in my cleaning tutorial):

Tools needed to go with a carder

If your carder doesn’t come with clamps to attach it to the table, then these are a very worthwhile investment to stop it moving around as you card and while you’re removing the batt. Here is a photo of the other tools I use with my carder:

tools

The three on the left came with the carder. They are:

Flick carder. Can be used for opening locks of raw fleece before carding, and also for cleaning the drum. I only use it for the latter, I prefer to open locks on a hand carder laid flat on my knee. To use it to clean the drum, hold it against the large drum while turning the handle the opposite way you’d turn when making batts (normally anticlockwise). Don’t move the flick carder from side to side while the drum is turning, do one rotation of the drum with it in one position, then stop and move it over.

Knuckle saving batt pick. This is used to get the batt off the carder. At one place on the drum there are no teeth. When the carder is full, you use this tool along the toothless part of the carder to separate the fibres, an inch or so at a time, until the batt is no longer joined.

Brush. This small brush looks a little like a nailbrush, and is used for cleaning the licker in drum. Due to the design of the cloth on the Strauch, the drum doesn’t get covered in fibre like some other models, but sari silk and angelina especially seem to want to get trapped on it, so brushing with this brush helps free them.

The other tools are my own, and I find they help considerably with using/cleaning the carder.

Long thin forceps. Even after cleaning the drum with the flick carder, there are sometimes a few stray fibres which remain. These forceps are thin enough to get inbetween the teeth to pick out any fibre left over after cleaning. They are also useful for pulling off any fibres which get wrapped around the axles of the drums. Note that while they are thin, the tips are not sharp, so they don’t damage the cloth.

Large needle. I use this to lift off the fibre from the flick carder after cleaning the drum.

Bristle hairbrush.  I couldn’t afford a carder with a brush attachement, so I run this over the drum between layers to squish down the fibres and enable the carder to take more fibre in one go.

How to use a carder, the basics

Most carders have a tray onto which you place the fibre. As the handle is turned, the licker in drum pulls the fibre in under the drum, and deposits it on the larger drum. The large drum turns faster than the smaller one (mine turns 5 times faster), so the fibres are pulled apart as they are deposited onto the drum, smoothing them out.

Here are a few tips which will help you get the best from your carder:

– Don’t put too much fibre into the feed tray at once. You should just be able to see the tray through the fibre. If you put too much on the handle will be hard to turn and the fibres may tear or get caught between the drums. If you are carding commerically prepped roving, you can use as long a length of roving as you like, just make sure the piece is thin enough that the carder runs smoothly.

– Guide the fibre in with your hand. Place your hand on top of the fibre in the feed tray and gently hold it in place, moving your hand as the carder pulls it in. Don’t pull back on the fibre, this will encourage it to wrap around the smaller drum, instead just gently guide it to keep it pulling in smoothly.

– Turn the handle slowly. After a little use you will be able to feel how fast you can turn it and still have the fibres deposited smoothly on the drum. Turning it too fast will be harder work, and may rip the fibres, causing nepps (lumps) in your batt.

– If your carder doesn’t have a brush attachment, get a bristle hairbrush and run this over the drum while turning it between layers. This will help compress the fibre and allow you to get more on the drum. This is especially useful with very fine fibres like angora, which want to fly away all over the place and don’t embed into the teeth on the drum easily by themselves.

– Don’t allow the fibre to ‘fall off’ the edge of the large drum and wrap around the axles or anywhere else on the carder, as this may damage it. It happens to everyone sometimes, but try and move the fibre as soon as it starts to do this, and pull it off the axle immediately.

– When removing the batt, use your doffing tool (or batt pick, or whatever your one is called) to free up just an inch or so of fibres at a time, if you try to do too much you’ll find it very difficult, and you may rip the fibres. Once the batt is separated, take the end furthest from the small drum, and roll the batt up, keeping your hands close to the drum so more of the stray fibres are kept within the batt. The drum will move by itself as you carry on rolling, until your batt is freed.

That is all I can think of at the moment, if you have any questions, please leave a comment and I will update with answers.
