Abstract
A rotary shear for trimming sheet metal has a main support beam extending perpendicular to a normal workpiece transport direction and symmetrical about a central upright plane extending in the transport direction, a pair of symmetrically identical housings carried on the beam and each displaceable therealong transverse to the direction, and respective pairs of upper and lower rotary trimming blades carried on the housings. The upper and lower blades are rotatable about respective common axes substantially perpendicular to the transport direction. The beam is of trapezoidal hollow section and has a generally planar upper surface formed by a family of parallel and horizontal lines and inclined downward against the transport direction. The housings are each provided with a slide having a planar lower surface lying generally flatly on the beam surface, and the housings and beam are provided with guides engageable parallel to the surfaces with each other. These guides extend horizontally perpendicular to the transport direction.
