Made it to the end!

30 July 2014

end of warp   As you can see , I made it to the end of the warp. No complications due to a full cloth beam, no slats or too many slats. As you can see here , only about 6″ of the warp is unwoven. This was not an obvious out come as the cloth beam looked very full, see previous post.  When I saw the cloth beam so full I stopped adding in the slats  that came off the warp beam. Winding on the cloth beam with out slats was worrisome to me. As you know, the tension on this loom, and many others, goes from where the warp is attached to the warp beam in the back to the cloth beam where it is tied on. Any irregularities in either beam can cause tension problems.  This is true from the beginning to the end of a warp, not just when you start.  The longer the warp the more chances there are for something to happen to the cloth  on the beam when winding on.  You probably know this instinctively.  When I get one loose section in a warp I can tighten it by padding either the back beam or the cloth beam. I usually do the cloth beam because it is in the front and more accessible and secondly , the padding won’t fall out with the next warp advance.  Padding in the cloth beam just becomes part of the beam and continues to do its function until the end. I use slats in both beams to prevent irregularities that cause tension problems.  Irregularities can be caused by knots, ropes, bars, warp threads cutting down to the lower layers or falling off the edge. BUMPS IN CLOTH

Here you can see a small irregularity caused by mending a broken warp.

 

Falling off the edge is by far the most problematic and common cause of tension problems.  Warp beams can be, and are often, wound without slats if the edges are supported.  I have flanges on my AVL that do this.  If you are using slats in your beams you want the slats to be stiff enough to stick straight out over the edge of the bundle  and keep the selvage warps the same length as the warps in the center of the beam.  Some people fold over the edges of the paper they roll into warp beams just to increase the stiffness of the edges.  The same falling off the edges can happen when you wind on the woven cloth onto the front beam. If the edges don’t line up precisely as you wind on the selvedges can become wonky.   So I put the slats into the cloth beam as they fall out of the warp beam.  They stick out of the cloth bundle and support the edges even if the edges don’t line up exactly.  In this project I stopped adding in the slats when I thought that the cloth beam might not hold all of the cloth that could be made with this warp. edge of cloth roll

In the photo you can see that the cloth edges do NOT line up precisely.

 

 

 

And after I stopped adding in the slats this can cause tension problems at the selvage.  Luckily this did not happen on this warp, the yarn is quite elastic and compensated for the uneven winding on.           This falling off the edge is more obvious here: These problems become more evident the longer the warp and with warps that have very little elasticity. I do not unwind the cloth beam during weaving because I don’t want to disturb the even tension that I have for weaving.  I have had gaps develop in my web following and unwinding episode.  There are fairly elaborate schemes to keep your tension as you have established it and cut off a portion of the woven cloth. It is true that if you have only woven one scarf at a time on a rigid heddle loom you may not have seen these problems.  But 40 yards of linen warp will test your mettle.   Back to the project at hand, one reason I chose to use a Rigid Heddle loom for this project was to minimize the waste.  Yet 200 ends of hand-spun yarn X 6″ waste on each gives 1200″ or 33 yards of waste! I hemstitched,  to stabilize the weft, before I cut it off the loom. hemstitched I am quite pleased with the look of the cloth while it is still on the loom.  It took a lot of extra effort to weave with the thick and thin singles  and I did get the look I was looking for. web It will close up some just taking it off the loom.  I will finish it gently to keep this look and just meld the threads together.  The yarn was lightly steamed to calm the twist before weaving.  Even so the twist was still active and the weft took extra attention.  The selvages look good now.  I expect they will look worse after washing because of the unevenness of the twist in the yarn.
