Abstract: A driving cam for seaming a container includes a cam base, an annulus, a bar, and first and second load cells. The annulus is defined by an internal profile and an external profile and is formed with an active sector. The active sector has a first end and a second end and is defined by the internal profile and the external profile. The external profile for defining the active sector is formed with an ascending ramp at the first end and a descending ramp at the second end with a plateau located between the ascending ramp and the descending ramp. The internal profile for defining the active sector is formed with a first recess at the first end and a second recess at the second end with a flat inner face located between the first recess and the second recess. The bar is connected to the cam base and is located within the annulus below the active sector. The load cells are connected between the bar and the flat inner face adjacent to the recesses.

Abstract: In this seaming driving cam 1 formed by an annulus, formed on an active sector 2 of which are, on the one hand, an external profile comprising an ascending ramp 3 and a descending ramp 5 and, on the other hand, an internal profile defining a plateau zone 10 between two deep recesses 6, there are load cells 13 held against the plateau zone 10 by an adjustable bearing part 14 in such a way that their electrical output signals are processed by an analytical device to produce a signal representing the force exerted by the cam 1 on a drive follower that rolls against it.

Abstract: Metal section for making a conductor element with double contact face, adapted to be cut into portions, or electrical contacts.This section comprises a base arranged to abut and be fixed on a face of the conductor element, and a body, extending on either side of the base, and having two opposite contact surfaces.
