Abstract
The device for embossing and perforating foils for tobacco goods includes: a pair of embossing rolls, one of the embossing rolls having teeth for perforating the foil, the counter roll to the embossing roll with the perforating teeth being a matrix roll which has recesses that correspond to the teeth on the patrix roll, both embossing rolls being arranged in a perforation device, and the device being designed in order to be operated directly or indirectly online in a machine for producing tobacco goods. The use of patrix-matrix embossing rolls allows for a large variety of perforations, the device having a control unit designed to control the exact position, size and arrangement of the perforations on the basis of the quality of the foil to be processed.
Claims16
A device for embossing and perforating foils for tobacco goods, comprising:
- a perforating apparatus including a pair of embossing rolls, one of the embossing rolls is a male embossing roll having teeth for perforating the foil, an opposing roll to the male embossing roll is a female embossing roll, which has depressions assigned to the male embossing roll, the perforating apparatus configured to operate online directly or indirectly in a production machine;
- a first control unit configured to control a precise location, a size and an arrangement of perforations of the perforating apparatus as a function of a character of a foil to be processed;
- and
- a sensor for detecting the character of the foil, the sensor configured to signal to the first control unit to detect and to define a position of LIP (Low Ignition Propensity) zones, embossed patterns, or printed patterns, to control the perforating apparatus in such a way that the perforations are made at desired points with respect to the LIP zones, embossed patterns, or printed patterns, by adjusting an operating cycle of the perforating apparatus.
