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. A device is provided for indicating the state of operation in each compartment (22) and preventing unintentional activation of tools which are out of operation, such that a tool can be safely exchanged at one working station wh…
