Title: FLEXIBLE PACKAGE-FORMING MACHINE FOR HORIZONTAL PACKAGING BY MEANS OF FOLDING AND WELDING A FLEXIBLE BAND AND METHOD
Abstract:
The present invention relates to a machine comprising: an unwinding unit (11) for unwinding a flexible band (1), a folding unit (14) of a flexible band (1), a drive unit (31) configured for moving the flexible band (1) in a forward movement direction (DA), a welding unit (16) and a cutting unit (17) for cutting the flexible band, wherein the cutting unit (17) is a laser beam cutting unit (53) separating each individual flexible package from the flexible band (1) and providing a fill opening in each flexible package by means of at least one fill opening cut. The laser beam cutting unit (53) has associated therewith a separator device, movable in a vertical direction and including an insertable separator element (41), interposed between the opposite faces of the folded flexible band (1), in an area adjacent to the fill opening (3), for separating the opposite faces of the flexible band (1) during cutting operations to prevent the fusion thereof.
