Abstract:
A machine for producing so-called strip packs, the machine including:a station for feeding products to a packaging group, situated in cascade, said packaging group comprising counter rotating rolls to place and seal each of said products in relative heat-welded pockets, arranged on a continuous band forming corresponding longitudinal and transversal rows of said pockets in a continuous non-stepwise operation; an operating station, situated in cascade with respect to said packaging group, aimed at supplying, at the outlet, a plurality of strip packs of predetermined longitudinal and transversal dimensions, said operating station being equipped with: means for printing and/or applying codified data and/or information on each pocket of said continuous band; feeling detecting means for verifying the presence of corresponding products inside each pocket of said continuous band; pre-cutting groups for transversal precutting of said continuous band in portions included between adjacent transversal files; cutting groups, a first cutting group and a second cutting group, respectively for longitudinal and transversal cutting of said continuous band in portions included between adjacent longitudinal and transversal rows; means for pulling the continuous band; a compensation magazine interposed between said packaging group and said operating station, for accumulating, at least partially and upstream of said operating station, said continuous band, so as to allows a variable configuration thereof; meaning for moving said continuous band stepwise and in step relation with the intermittent and synchronous operating of said, printing means and pulling means, said feeling detecting means, said pre-cutting groups and first cutting group and second cutting group, working in said operating station downstream of said packaging group.
