Abstract
A trimming shears for sheets and strips having two shears frames arranged opposite one another and on supports and being rotatable about a central vertical axis. A pair of vertically stacked adjustable roll blades are mounted in each shears frame at diagonally opposite horizontal corners of the shears frames. The roll blade pairs are rotary driven by gears and couplings to cut the sheet or strip edges. The roll blade pairs are adjustable both vertically and horizontally to accommodate different material thicknesses and widths. The roll blade pairs are arranged in the shears frames such that when the shears frames rotate 180.degree. about the central vertical axis, the position of the roll blade pairs is transposed--with the first roll blade pair taking the position of the second roll blade pair.
