Patent ID: 6948414

Claim:
A cutting subassembly for machines by means of which a workpiece is machined in order for edge-material overhangs projecting beyond at least the front or rear transverse sides of the workpiece to be cut off, said transverse sides of the workpiece being oriented substantially transversely to a movement direction of the workpiece, which cutting subassembly is provided on longitudinal sides of the workpiece, said longitudinal sides running parallel to the movement direction, said cutting subassembly comprising: a saw unit which comprises a motor-driven saw blade being mounted for displacement between a position above the workpiece and a position beneath the workpiece; a contact element associated with the saw blade and having a first contact surface for engaging against a front transverse side of the workpiece as seen in the movement direction and a second contact surface for engaging against a rear transverse side of the workpiece as seen in the movement direction; and a piston/cylinder subassembly for pivoting of the saw blade; wherein: the saw blade is mounted such that it can be pivoted in relation to both the front and rear contact surfaces, between a first operating position for each contact surface, in which a cutting plane of the saw blade is oriented in alignment with a respective contact surface, and a second operating position for each contact surface, in which the cutting plane of the saw blade is obliquely in relation to the respective contact surface; the cutting subassembly comprising adjustable stops for orienting the saw blade in its first, aligned operating position and its second, obliquely oriented operating position; and the contact element and the saw blade are mounted such that they can be displaced in relation to one another.
