Abstract
Abstract An apparatus for cutting lengths of fabric pulled from a selected roll on a rotary magazine. A transverse carriage 15 is movable along the side rails 14 of a table 12 and carries grippers 19 for pulling off a selected length of fabric. A transverse cutter 16 severs the fabric at the end of the pull and the stacked fabric layers 10 are held tightly at one end by a clamp 17. As a length of fabric is being drawn out from a selected roll, side edge drifts are sensed and the magazine is automatically moved in a direction opposite to the drift to compensate therefor and maintain the stacked layers neatly aligned.
