Date Sep. 19, 1991.A panel bender which can remarkably improve productivity in a bending process, and can feed in and out works having different widths with a single conveyer without causing interference between a main body and the conveyer has a construction in which a plurality of main bodies (1) are provided at opposite positions across a conveyer (16) for feeding the work (A) to a working position within the panel bender, each of the main bodies being movable in a back and forth direction with respect to the other by a back and force feeding device (13). The conveyer (16) disposed between the main bodies is adapted to expand and contract in the width direction in cooperation with back and forth movement of the main bodies.
