Title:
METHOD OF CUTTING LONG-SIZED PRODUCT WITH JOINT
Document Type and Number:
Japanese Patent JPS62152695
Kind Code:
A
Abstract:
In a method and apparatus for cutting a chain of longitudinally joined elongate products (ll) into pieces (l2) of a desired length, the chain of elongate products (ll) is intermittently fed by a feed unit (l6) through a first distance equal to the length of each piece (l2) to be severed, along a path through a detector (l5) and a cutting unit (l7) downstream of the detector (l5) and the chain (ll) is cut successively into pieces (l2) of the desired length ( l) at the cutting unit (l7) while the feed unit (l6) is inoperative. As the chain (ll) is advanced, the joint portion (l3) of each adjacent pair of the elongate products (ll) is detected by the detector (l5). Upon detection of the joint portion (l3), a control unit (35) computes the number of prospective pieces (l2) of the desired length ( l) producible by severing from a longitudinal portion (L) of the chain (ll) which extends from the present leading end of the chain toward the detected joint portion (l3) and terminates short of the detected joint portion (l3). When the computed number of pieces (l2) have been severed, the chain (ll) is advanced by a second distance until the detected joint portion (l3) is located downstream of the cutting unit (l7). The chain (ll) is cut to produce a severed piece (l2 a) including the detected joint portion (l3) which is received in a reciporcably movable container (33).
