Purpose: monitoring the seaming process to eject the bad cans and control the seamer deviation.
The technique consists in examining the quality of the seaming of each can in real time as it passes through the seamer.
This technique is based on measuring the instantaneous seaming force on each can and analysing this force signal using a microprocessor and specific fast-processing software.
This means that when the cans emerge from the seamer, the system identifies whether they have been weel or badly seamed.
In order to achieve this, the cam must be modified slightly so that the sensor devices, which will give rise to an electrical signal proportional to the force being tested, can be built into it.
