MASSACHUSETTS-BEEHIVE OF BUSINESS 217 O Underwood & Underwood A WARPING-MACHINE ]N AN UP-TO-DATE TEXTILE FACTORY Here is shown the process of assembling the warp threads on the "loom beam" ready for weaving cloth. After the yarn has been sufficiently twisted to give it the required strength for warp, it is wound on spools. The contents of these spools, in turn, are wound upon the large rolls seen in the foreground, some 400 threads to the roll. These rolls are placed in the creel, or frame shown at the left in this picture, perhaps six at a time. There the threads are unwound from them, and, passing through a "slasher," or stretching and drying machine, they are consolidated on one great roll known as the loom beam. The loom beam may be seen on the right. With its load of thread, perhaps 2,400 individual strands, this loom beam is put into the loom (see next page, 218), and each thread through its particular "eye" in the loom harness, and then the conversion of thread into cloth-weaving-is ready to begin (see text, page 220).
