Knot tying

Once a warp beam has run out of yarn, the next beam with its yarn must be tied in. This is performed by the means of a knotting-machine, a precision job where each thread must be aligned correctly. By doing the knot tying you save an excessive amount of time compared to setting up all the threads through the loom all over again. The knot tying, when installing a new warp, consumes about 2 hours of work which includes pulling the threads with the knots all the way through the loom to make it ready to start weaving again.
