摘要

The appts. to stamp mounting eyelet holes in fabric or plastics claddings, for the bonnet and boot lid sections of vehicles, has the cylindrical zone for the inner piston contained within the outer piston. A single hydraulic feed serves the cylinder chamber of the outer piston with a bypass to lead to the cylinder chamber of the inner piston to bring the upper tool down to the lower tool. When the cutting position has been reached, by the inner piston, the outer piston with the flanging section of the upper tool is further depressed.
