High speed trimming shear

A high speed rod trimming shear includes a pair of eccentrically bored sleeves mounted for rotation about parallel first axes. Carrier shafts are supported in the bores of the eccentric sleeves for rotation about second axes parallel to the first axes and located on opposite sides of the rod path. The carrier shafts have blade holders with attached cutting blades. A primary drive rotates the carrier shafts continuously, and an adjustment mechanism rotatably oscillates the eccentric sleeves to adjust the distance between the carrier shafts between a first setting at which the cutting blades rotate out of contact with the rod, and a second setting at which the cutting blades coact during rotation to sever the product.
