Abstract
A method of warp thread drawing-in for warp thread machines having at least one warp thread magazine, heald frame, and reed comprises the steps of placing the warp thread magazine, heald frame and reed from the warp thread machine on a warp thread charging device which is separate from the warp thread machine; passing warp thread groups, comprised of one or more warp threads, in stages through a respective heddle of a heald frame; assigning each of the warp thread groups a space in the reed; drawing each of the warp thread groups through its respective space with an automatic reeding device, the automatic reeding device being movable along a width of the reed as the drawing step is carried out; transferring the warp thread magazine, heald frame and reed from the warp thread charging device to the warp thread machine and returning the warp thread magazine, heald frame and reed to their operational positions in the warp thread machine. A warp thread charging apparatus is also disclosed.
