Horizontal packaging machine with adjustable cut-sew group

Abstract

A horizontal packaging machine for packaging a product fed in a horizontal direction comprising a control panel and a cut-sew group to make on a packaging film transverse welds and a cut to close and separate from each other two successive packs. The cut-sew group comprises a plurality of cut and sew tools to make said transverse welds and the cut. The transverse welds define the edges of the packs according to different packaging sizes for said product. The horizontal packaging machine can change the size of the aforesaid packs simply by selecting through the control panel one of the cut and sew tools of the plurality present in the cut-sew group, and by positioning said cut-sew group so that the product to be packaged is fed at said cut and sew tool selected to make the packs according to a prefixed and set size through the control panel. The cut-sew group comprises an upper shaft and a lower shaft independently controlled in rotation by means of a respective upper motor and a respective lower motor. Each shaft mounts on it said plurality of cut and sew tools and wherein each cut and sew tool consists of an upper tool and a corresponding lower tool. Each cut and sew tool comprises one or more heat-sealing spatulas to make said transverse welds for closing the packs and one or more cutting elements to make said cut which mutually separates two successive packs.
