Abstract

733,172. Shearing; angular bending. DUNLOP RUBBER CO., Ltd. July 14, 1953 [July 15, 1952] No. 17793/52., Class 83 (4). Apparatus for cutting successive predetermined lengths from metal strip or wire comprises means for continuously feeding the strip to cutting means, means for moving the cutting means in the direction of feed of the strip at the speed of the strip feed and for returning the cutting means to its initial position, and means for operating the cutter while the cutting means is moving in the direction of the strip feed, which comprise a block which may be rocked to a position inclined to the direction of strip feed and is engaged by a member secured to the cutter. Metal strip passes between guide rolls 1a, rolls 1b which partly shape it into channel section and rolls 1c which complete this shaping to a severing die assembly 2, reciprocable by cam-operated lever and link means 18, 21, on guides 11 in the direction of travel of the strip, which severs predetermined lengths from the shaped strip. The die assembly 2 comprises a block 10 carrying a fixed die 7 and a vertically reciprocable die 8, which co-operates with the die 7 to sever strip passing through the dies. A rod 12 extending downwardly from the die 8 carries a roller 13 engaged in a slot 14 in a pivoted block 15. The block 15 is rocked by cam-operated lever and link means 24, 27 to incline the slot 14 downwards and forwards as the die assembly 2 is moved forward with the strip, so that the die 8 is caused to sever the strip. Before the die assembly 2 reaches the limit of its forward position the slotted block 15 is returned to the horizontal, and as the assembly reaches its forward limit a tapered aperture 31 in the die member 8 is engaged by a spring pin 29 on the machine frame to ensure exact alignment of the apertures of the dies 7, 8 so that as the assembly 2 moves back the strip is allowed to pass unhindered through the dies.
