ABSTRACT:
A device for controlling the sealing of seams of thermoplastic overwraps for packets of cigarettes. A wrapping wheel has a plurality of sealing stations for heat-sealing one single seam of the overwrap of each packet. In each station a heat-sealing contrivance can contact the seam during a halt of the wheel. The total contact time, that is, the sum of the individual times of contact between the several sealing contrivances and the overwrap, is controlled in response to the operating speed of the machine. For this purpose the several sealing contrivances, each connected for a reciprocating motion, are installed, one in each sealing station, and have a control system sensitive to variations in the operating speed of the machine, to trip the means for reciprocating them individually, to suit different speed levels of the machine.
