Abstract: A device for a woodworking machine (13) adapted at a number of consecutive working stations (14) for processing workpieces which are fed through the machine. The required working of the workpieces can be effected with at least one working station out of operation. The working stations are separated from each other by partitions (20) which extend between external walls (11), a roof (12) and a base and which are closely associated with the machine on either side of the working stations (14) and, like the external walls and the roof, are sound-proof. The tool or tools at each working station can be driven independently of the tools at the other working stations, and each compartment (22) defined by the partitions has a door (21) in the external wall (11). The path of travel of the workpieces through the machine is laterally limited by vertical walls and at the working stations the walls can be provided with covers for forming tunnel portions at these locations.

Abstract: The disclosure relates to a tool consisting of a tool body and cutter bits which are each secured in a slot in the body. By means of a tension screw which engages with the end portion of the bit located most proximal the bottom of the slot, the bit is fixedly retained in the slot under the application of a torque, the bit engaging with the slot walls at, in particular, three points; namely a point on the chipping face of the bit above a clearance disposed between this face and the slot face adjacent the bottom of the slot, a point on the rear face of the bit adjacent the periphery of the tool body, and, finally, the bottom of the slot. The tension screw engages with a surface on the bit which is located beneath a plane at right angles to the longitudinal direction of the bit through the abutment point on the chipping face of the bit, the surface preferably making an angle of approximately 45.degree. with this plane.
