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.
