Abstract
Flying cropping shears for hot strip for two horizontally spaced pairs of cutters. The cutters are driven by parallel crank drives through connecting members which maintain parallelism of the cutters. Means are provided for selectively bringing the pairs of cutters into and out of the cutting position. In this way only one pair of cutters is operative during rotation of the crank drives so as to crop either the front or the rear end of the hot strip.
Claims6
In a parallel crank flying cropping shear for hot strip including upper and lower parallel connecting members, each of said connecting members including means synchronizing one connecting member with the other connecting member for synchronous counter-rotation of the connecting members, said parallel crank cropping shear further including the improvement comprising:
- two pairs of cutters, one of each pair being mounted on the upper connecting member and the other of each pair being mounted on the lower connecting member, said synchronizing means including means for maintaining parallelism of said upper and lower cutters in a pair;
- and
- means for selectively bringing one of said pairs of cutters into a cutting position and for bringing the other of said pairs of cutters out of the cutting position.
