Abstract:
A driving cam for seaming a container configured to cooperate with a rotating drive follower to generate signals to be processed by an analytical device, the driving cam comprising:a cam base; an annulus defined by an internal profile and an external profile and being formed with an active sector, said active sector having a first end and a second end and being defined by said internal profile and said external profile where: said external profile is formed with an ascending ramp at said first end and a descending ramp at said second end with a plateau located between said ascending ramp and said descending ramp; and said internal profile is formed with a first recess at said first end and a second recess at said second end with a flat inner face located between said first recess and said second recess; a bar connected to said cam base and located within said annulus below said active sector; a first load cell connected between said bar and said flat inner face adjacent to said first recess; and a second load cell connected between said bar and said flat inner face adjacent to said second recess, wherein said first and second load cells are configured to generate electrical output signals for processing by the analytical device that represent a force exerted by said annulus on the drive follower.
