ABSTRACT:
A cut-off machine for cutting off predetermined lengths from a moving length of roll form material such as tubing adapted to be positioned downstream from a source such as a tube mill for receiving a moving length from the mill and severing plural predetermined lengths from the moving length. The machine comprises a plurality of cut-off assemblies which are reciprocated longitudinally of the moving length of material formed by the mill and operated during the movement to sever plural predetermined lengths. The reciprocating and cutting movements are mechanically derived from a motor driven in synchronism with the speed of movement of the moving length. The apparatus includes mechanisms that permit the length of the tubes to be changed while the machine is operating.
