A crimping device has for each crimper an anvil including a conductor anvil provided with a force sensor on which the force that arises in the conductor anvil during the crimping operation acts. The conductor anvil rests on a sensor body which in turn rests on a supporting part of the crimping device. The force sensor measures the force that is required to manufacture the conductor crimp, the quality of the crimped fastening being assessable by reference to the force curve generated by the force sensor.

A laminate is made by first non-crimping or low-crimping continuous filaments to form a first spunbond layer and preconsolidating the first spunbond layer with a heated or calendering roller. Then continuous filaments with a greater crimp than the continuous filaments of the first spunbond layer are deposited as a second spunbond layer over the first spunbond layer to create a two-layer structure. Finally, the two-layer structure of the first and second spunbond layers is consolidated such that a total thickness of the laminate is 0.15 to 3 mm, preferably 0.2 mm to 2.5 mm and especially 0.2 mm to 2 mm.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.
