Abstract
The device for packaging continuous webs of materia1, such as selvedges generated on thermoforming units, includes an input regulator of webs, driving guide for the webs, a cutting unit and, downstream thereof, a collector for bits of webs. The cutting unit has at least a blade actuated imparted with a reciprocating movement co-operating with a cutting block, and the driving guide is associated with a conveyor by air stream for the webs, preceding immediately the blade and the cutting block.
Claims8
An apparatus for packaging continuous webs of material comprising:
- a means for controlling an input of the webs of material;
- a means for guiding and driving the webs of material positioned downstream of said means for controlling;
- a means for cutting the webs of material into pieces, said means for cutting positioned downstream of said means for guiding and driving;
- and
- a means for collecting the pieces positioned downstream of said means for cutting, said means for cutting comprising:
- at least one cutting block;
- and
- a cutting blade in which the blade is actuated in a reciprocating movement cooperating with said cutting block, and said means for guiding and driving having a means for conveying the webs by an air flow arranged immediately before the blade and said cutting block.
