Warping machine
Warping machines serve as beaming machines producing warps .
A warping machine consists of a frame or drum with a circumference of up to 58 meters. The most widespread is the conical warping machine. Here a group of threads in the thread density of the later warp is wound onto the drum and warped. In order to prevent the edge threads from sliding down from the underlying thread after several turns and thus after a certain thickness of the thread layer, it is warped along a cone. This creates a new cone on the opposite side of the original cone. This is used for the next group of threads like the first. When the warp has the final thread count, it is unwound again from the warping frame or drum and wound onto a warp beam. Nowadays the warp beam has two warp beam discs that prevent the edge threads from slipping off.
Once the warped chain is made from twine , it is ready and can be delivered to the weaving mill. If it consists of simple yarn , it is sized , i.e. strengthened, in the sizing machine .
