Open the CIPO recordAbstract From the Canadian patent
A waste stripping tool comprises a grid of bars consisting of traverses held side by side by a flange. The flange consists of a strap within which are arranged two jaws having two triangularly profiled teeth engaging in the grooves existing on the upper and lower faces of the traverses. A screw engages in the intermediate plate and presses on the upper jaw in such a way that, owing to the wedge effect the traverses, are strongly pushed against one another. The tool is utilized in the stripping station of a sheet diecutting machine and allows the number of bars of which the stripping frame consists to be reduced.
