VARIABLE GEOMETRY PROTECTOR DEVICE FOR WOOD FORMING MACHINES.

摘要

The device is provided to be applied to wood forming machines, called "shapers" or millers, machines which perform the milling of regular or irregular profiles of wood parts. The protector is mounted as a whole on a pair of vertical columns (14) previously fixed to the corresponding working table or platform of the machine, the device being comprised of a pair of rings (1) mounted rotationally between two parts (2 and 3) forming an assembly or headstock which is fixed to said columns (14) by means of a pair of parts (10 and 11) slidingly mounted on two emerging bars (9) integral with the headstock, said parts (10 and 11) being complemented with other parts (12 and 16) which, by means of fixing and regulating screws, allow to displace the headstock assembly with respect to the milling cutter, in order to regulate the bite depth of the milling cutter. The rings (1) which are provided with tangential arms (6) having at the ends thereof cylindrical stops or rollers (7) appropriately positioned by the machine operator ensure a smooth and safe admission of the wood part for the operation of the milling cutter.
