ABSTRACT:
A force limiting cartridge comprises a housing and end cap which screw together to contain a slidable piston biased by a coil spring. The cartridge surrounds a conventional pull-up clamp. The bottom end of the cartridge pushes against the top layer of the laminate. The piston is pushed against the spring when the clamp screw is tightened. The piston is provided with a cross mark which when aligned with cross hairs on the housing indicate a desired clamping pressure has been attained. The cartridge can be calibrated to any desired pressure (depending on the spring's performance characteristics) by adjusting the total length of the housing/end cap assembly.
