ABSTRACT OF THE DISCLOSURE The present invention provides a device for controlling the sealing of wraps of thermoplastic material, particularly on machines that overwrap, for example, packets of cigarettes in succession along a wrapping line at various operating speeds and in a plurality of sealing stations for one single position to be sealed on the individual packets by means of sealing devices provided with complementary heating means with which to seal the wrap at a speed compatible with the individual speeds. The sealing devices are connected to cam means adapted to cause the sealing devices to operate with a reciprocating motion and which work in conjunction with control means connected to means sensitive to variations in the speeds of the machine, which trip the aforementioned operating means so that the sealing action of the sealing devices is put into or out of operation to suit the operating speeds of the machine detected by the means that are sensitive to variations therein. The device is provided with heat-sensitive control means connected to the sealing devices and arranged following the switching in of the said sealing devices in their respective operative sealing positions when the corresponding speed of the machine has been restored, to operate means that follow up the reciprocating motion cam operating means provided with differentiated operating time multiple tracks, so as to operate the said sealing devices in a differentiated succession commensurate with the temperature detected in the said sealing devices by the said heat-sensitive control means.
