Blank joining module with register control

A blank joining module comprising:

• an upper feeder device configured to feed an upper blank,
• a lower feeder device configured to feed a lower blank,
• an upper conveyor system configured to transport the upper blank from the upper feeder device,
• a lower conveyor system configured to transport the lower blank from the lower feeder device, the upper and lower conveyor systems being configured to transport the upper and lower blanks towards a junction point where the upper blank is positioned onto the lower blank, and
• a register control arrangement comprising a sensing system and a position correction device, wherein the sensing system comprises an upper transfer sensor configured to detect a passage of the upper blank and a lower transfer sensor configured to detect a passage of the lower blank, and
• wherein the register control arrangement further comprises a control unit and a memory, the control unit being configured to receive detection signals from the upper and lower transfer sensors and calculate a total relative displacement between the upper blank and the lower blank, the control unit being further configured to activate the position correction device to provide a correction displacement to the upper blank such that the upper blank is displaced to be aligned to the lower blank.
