Method for manufacturing a suspension bag with suspension hole

#The present invention relates to a method for manufacturing a bag with enclosed goods to be packaged and with a suspension having a suspension hole, wherein the goods to be packaged are introduced into a foil hose which is supplied transverse to the transport direction, is deflected by a deflecting device, and is then further transported in the transport direction together with the goods to be packaged on a transport path, and is then separated from the foil hose and simultaneously welded by means of a transverse welding unit.

#Such bags, so-called polybags, are generally known. They are suitable to be suspended from a hook or from rods projecting from a wall, wherein the packaged goods are arranged below the suspension within the bag. The suspension hole is usually a so-called “Euro hole”, i.e., a suspension hole which is standardized within Europe.

#These known bags have the disadvantage that the suspension hole, especially the Euro hole, can easily tear because of the weight of the enclosed packaged goods.

#In the following, the method will be explained with the aid of the accompanying drawings, wherein:

#FIG. 1 shows the basic features of the present invention; and

#FIG. 2 shows the packaging bag with a reclosing flap produced according to the method of the present invention.

#The foil semi-hose 1 is supplied transverse to the transport direction of the goods 2 to be packaged and is deflected in a manner known in the art by means of a forming shoulder 3 and then combined with the supplied goods to be packaged. The reinforcement strip 4 is introduced along the longitudinal edge 5 of the forming shoulder 3 into the foil semi-hose 1 and is thus positioned in the folded edge area of the foil hose. First, by means of a sealing welding action 6 a welding seam 14 is provided between the goods 2 to be packaged and the reinforcement strip 4. In the next step, the Euro hole welding is carried out by a welding or stamping device 15 and, at the same time, a separation of the bag by means of a transverse welding device 7 is performed. In the process sketch a lateral welding device 8 is indicated in an exemplary fashion by which the third side of the packaging bag 9 is closed.

#FIG. 2 shows a packaging bag 9 with introduced goods 2 to be packaged which is closed by a reclosing flap 10. In the area of the suspension the packaging bag is formed of three layers and comprises an upper and a lower foil layer as well as an interposed reinforcement strip 4 which may be printed. Between the reinforcement strip 4 and the goods 2 to be packaged a sealing welding seam 14 is arranged in order to provide the desired shape to the packaging bag and to prevent sliding of the introduced objects. In the area of the reinforcement strip 4 the suspension hole 13 the form of a Euro hole is arranged.
