Abstract (en)
Apparatus suitable for the continuous flow formation of tubular bags, starting with a film, for example, made of heat-sealable plastic synthetic material, particularly for the packing of loose foodstuffs supplied by a pre-packed filling and forming pipe obtained from tubular bags of the type with the longitudinal corners reinforced by sealing, said film unwound from a coil or extrusor upstream of the apparatus is forced by means of a collar to be turned, in such a way as to wrap the vertical filling pipe, and in which the forming of the corners takes place starting with the film that first assumes a rectangular section generated by the collar, and then, by means of deforming plate components that make provision for the entry of four sides, generating the four corners with folded flaps that once folded and sealed form the four longitudinal reinforcements.
