Definitions

  • the subject of the present invention is a process for forming the bottom of a flexible plastic bag from a plastic cushion filled with liquid, and for giving it stability.
  • the subject of the invention is also the sachets obtained according to this method and the device for its implementation.
  • one of the problems posed is that of the stability of the bag, obtained by a specific conformation of the bottom of the bag to allow it to be placed on a flat surface.
  • the bottom of the sachet is shaped like a W by folding the plastic film before filling.
  • French patent 71.20879 proposes to shape the bottom by welding and cutting the angles forming ears after folding the bottom. In these embodiments, it is imperative that the bag is empty.
  • the two proposed embodiments are necessarily made from empty bags, at a given stage of their conformation.
  • this result is obtained with a process for forming the bottom of a flexible synthetic bag, from a cushion of synthetic material filled with liquid, and for giving it stability, which consists in pinch each of the two lower corners of the cushion with pliers, to wrap said corner around itself around the axis supporting the pliers, according to a determined number of rotations, then finally, after immobilization and removal of the pliers, to weld the roller thus formed.
  • a cushion (1) filled with liquid (2) is intended to be shaped into a sachet, from a continuous vertical or horizontal path, in this case preferably vertical.
  • each of the corners (3,4) is grasped using a clamp (5) integral in rotation with an axis, shown, driven by a motor; the clamp opening and closing controls are inside the axis.
  • a device allows the release of the axis and the clamp after winding.
