ABSTRACT:
In a method and apparatus for cutting a chain of longitudinally joined elongate products into pieces of a desired length, the chain of elongate products is intermittently fed by a feed unit through a first distance equal to the length of each piece to be severed, along a path through a detector and a cutting unit downstream of the detector and the chain is cut successively into pieces of the desired length at the cutting unit while the feed unit is inoperative. As the chain is advanced, the joint portion of each adjacent pair of the elongate products is detected by the detector. Upon detection of the joint portion, a control unit computes the number of prospective pieces of the desired length producible by severing from a longitudinal portion of the chain which extends from the present leading end of the chain toward the detected joint portion and terminates short of the detected joint portion. When the computed number of pieces have been severed, the chain is advanced by a second distance until the detected joint portion is located downstream of the cutting unit. The chain is cut to produce a severed piece including the detected joint portion which is received in a reciporcably movable container.
