Definitions

  • the invention relates to a method of forming tube-like bags made of a single roll of a band-shaped package material in particular to the bags having stiffened welded edges including bags provided by closures and to a device for carrying out this method.
  • the object thereof is in particular the configuration of longitudinal jaws where two jaws are disposed on one side of a filling pipe and form welded edges stiffening the bottom of the bag while one jaw is located on the other side of the filling pipe and forms a weld on the upper bag wall.
  • the published patent application DE 101 59 053 A1 discloses a method of making bags having lengthwise welded edges. Its object is particularly a structure where all welded edges of a package material are made before the rolling of this material into a tube.
  • Said disadvantages are to a substantial extent eliminated by using a method of forming tube-like bags provided with stiffening lengthwise welded edges formed from a single role of a band-shaped package material.
  • the object of the invention is that primarily a first stiffening lengthwise welded edge is formed on the band-shaped package material. Thereafter, the package material including the first stiffening lengthwise welded edge is rolled into an unclosed tube on which a second stiffening lengthwise welded edge and a third stiffening lengthwise welded edge is formed.
  • the third stiffening lengthwise welded edge may be situated in the bottom or on the top of the bag.
  • the closure is inserted between the inner surfaces of the band-shaped package material, whereupon the third stiffening lengthwise welded edge is formed. In this way the closure is tightly joined to the inner surfaces of the band-shaped package material and a bag provided with the stiffening welded lengthwise welded edges and the closure is formed.
  • a device for performing said method comprises a station for forming and welding the first stiffening lengthwise welded edge, a profiling collar for profiling the tube, a filling pipe including a spacing member for forming the second stiffening lengthwise welded edge, first longitudinal welding jaws for welding the second stiffening lengthwise welded edge, second longitudinal welding jaws for welding the third stiffening lengthwise welded edge, a tube feeding equipment and transversal welding jaws provided with a separating knife.
  • the station for forming and welding the first stiffening lengthwise welded edge is located ahead of the profiling collar.
  • the spacing member, the first longitudinal welding jaws for welding the second stiffening lengthwise welded edge and the second longitudinal welding jaws for welding the third stiffening lengthwise welded edge are located behind the profiling collar.
  • the device for forming and welding the tube-like bags having the stiffening lengthwise welded edges provided with a closure comprises a feeder including a supply line for the supply of closures.
  • the station for forming and welding the first stiffening lengthwise welded edge, the first longitudinal welding jaws, the second longitudinal welding jaws, the feeder, the tube feeding equipment, and the transversal welding jaws including the separating knife are adapted for both the discontinuous and continuous passage of the package material through the device.
  • One advantage of the method and device according to this invention is that in the area surrounding the filling pipe not all longitudinal welding jaws are situated what enables to produce even very small bags of a package material capable to be welded on one side only or on both sides using both the discontinuous or continuous movement of the package material.
  • Another advantage is the possibility to use a suitable closure inserted into the third stiffening lengthwise welded edge.
  • the closure may be located either on the top or in the bottom part of the bag.
  • the bag provided with a closure is suitable specifically for packing liquids.
  • a first longitudinal fold is formed on a band-shaped package material 1 (Fig. 1), which fold is welded and a first stiffening lengthwise welded edge 5 is formed.
  • the package material 1 including the first stiffening lengthwise welded edge 5 is formed into a tube 6 which remains unclosed in its longitudinal direction and is rolled around a filling pipe 4.
  • a second longitudinal fold is then formed on the filling pipe 4 and this fold is subsequently welded to form a second stiffening lengthwise welded edge 8.
  • the tube 6, which is still being unclosed in its longitudinal direction is welded in the longitudinal direction and in the bottom of the bag 15 a third stiffening lengthwise welded edge 12 is formed.
  • a band-shaped package material 1 In forming tube-like bags made from a single role of a band-shaped package material 1 , more specifically bags 20 stiffened by three stiffening lengthwise welded edges 5, 8 and 12 (Fig. 6), primarily the first longitudinal fold is formed on the band-shaped package material 1 (Fig. 4), which fold is welded and the first stiffening lengthwise welded edge 5 is formed.
  • the package material 1 including the first stiffening lengthwise welded edge 5 is formed into the tube 6 which is still unclosed in its longitudinal direction and is rolled around the filling pipe 4.
  • the second longitudinal fold is then formed on the filling pipe 4 and this fold is subsequently welded to form the second stiffening lengthwise welded edge 8. Simultaneously, the tube 6, still being unclosed in its longitudinal direction is welded lengthwise and the third stiffening lengthwise welded edge 12 is formed on the top of the bag 20.
  • a closure 16 In forming tube-like bags 19 stiffened by three stiffening lengthwise welded edges 5, 8 and 12 and provided with a closure 16 (Fig. 8) primarily the first longitudinal fold is formed on the band-shaped package material 1 (Fig. 7), which fold is welded and the first stiffening lengthwise welded edge 5 is formed.
  • the package material 1 including the first stiffening lengthwise welded edge 5 is formed into the tube 6 which is still unclosed in its longitudinal direction and is rolled around the filling pipe 4.
  • the second longitudinal fold is then formed on the filling pipe 4 and this fold is subsequently welded to form the second stiffening lengthwise welded edge 8.
  • the closure 16 Before welding the third stiffening lengthwise welded edge 12 the closure 16 is inserted between the inner surfaces of the band-shaped package material 1. Subsequently, upon welding the second stiffening lengthwise welded edge 12 the closure 16 is tightly joined to the inner surfaces of the band-shaped package material 1 .
  • a device for forming bags 15 stiffened by three stiffening lengthwise welded edges 5, 8 and 12 comprises a formation station 2 (Fig. 1) for forming and welding the first stiffening lengthwise welded edge 5 on the band-shaped package material 1 .
  • a profiling collar 3 is situated to form the band-shaped package material 1 into an unclosed tube 6 comprising the first stiffening longitudinal edge 5 .
  • a profiling collar 3 is connected with the filling pipe 4 which is disposed below the profiling collar 3.
  • To the filling pipe 4 in the area below the profiling collar 3, a forming spacing member 7 for forming the second stiffening longitudinal welded edge 8 is fixed. Below the spacing member 7 first longitudinal welding jaws 9 for welding the second stiffening lengthwise welded edge 8 are situated.
  • second longitudinal welding jaws 11 (Fig. 2) are disposed to weld a third stiffening welded edge 12.
  • a feeding equipment 1 0 for moving the tube 6 is situated below the filling pipe 4 .
  • transversal welding jaws 13 for making a transverse weld 14 are situated below the filling pipe 4 transversal welding jaws 13 for making a transverse weld 14.
  • the transversal welding jaws 13 include a separating knife for the separation of the filled up bag 15 from the remaining part of the tube 6.

  • transversal welding jaws 13 for making a transverse weld 14 are situated.
  • the transversal welding jaws 13 include a separating knife for the separation of the filled up bag 20 from the remaining part of the tube 6.
  • a device (Fig 7) for forming bags 19 (Fig. 8) stiffened by three stiffening lengthwise welded edges 5, 8 and 12 and provided with a closure 16 includes in addition a feeder 17 comprising a supply line 18 for supplying the closures 16.
