Definitions

  • the invention relates to a device for the production of bags by means of a stepwise rotating mandrel wheel cooperating with folding members, whereby said mandrel wheel has arranged thereon groups comprising each two parallel folding mandrels, and in which bag material blanks are placed at a treatment station on the two parallel folding mandrels to be formed by the latter into hose-like jackets, covers, or wrappings.
  • the size of the folding boxes is determined by the dimensions of the bag material blanks, which on their part depend on the size of the bags to be produced.
  • the invention is characterized by two folding boxes pressing the blanks on the mandrels moved consecutively out of the inclined or arcuate path.
  • the two folding boxes may be arranged in I their feeding position, in which one blank at a time is fed to them, adjacent one another, while each folding box may engage in its contact pressure position partially in thespace which is required by the other folding box.
  • the production loss through the treatment step at this station, stacked as to time, is substantially less than upon utilization of a mandrel wheel with solely one folding mandrel per treatment station.
  • the drawing illustrates by way of example an embodiment of the device of the invention.
  • FIG. I is a plan view of a portion of a mandrel wheel, with each two parallel folding mandrels and at one treatment station with two folding boxes;
  • FIG. 2 is a side elevation view of the treatment station shown in FIG. 1;
  • FIGS. 3a, 3b and 3c illustrate diagrammatically each a dif- I ferent working position of the two folding boxes.
  • the mandrel wheel 1 of which only a portion is shown in FIG. I rotates with each twoparallel outwardly extending folding mandrels 2a, 2b stepwise or intermittent in direction of the arrow, in such manner that the folding mandrels 2a, 2b
  • the plates 1 la, Ilb are arranged on the upper ends of. vertical rods 12a, 12b, which are guided coaxially in vertical posts 13a, 13b which on their part may perform a lifting movement independently of the rods 12a, 12b.
  • the posts l3a,'l3b carry on their upper ends folding forks 14a, 14b which serve for placing the blanks against the side walls of the folding mandrels.
  • the folding forks 14a, 14b are moved through recesses 17 in the folding boxes 3a, 3b.
  • compressed air conduits 15 are provided which terminate in nonles 16.
  • the jets of air issuing from these nonles serve for the alignment of the blanks in front of the folding forks 14a, 14!), so that the latter during their operating stroke place the blanks firmly against the side walls of the mandrels 2a, 2b.
  • the modus operandi of the device is as follows: As shown in FIG. 30, there is conveyed in the illustrated feeding position to each folding box in a manner known'per se a blank of the packaging material shown in dotted-dash lines. Now first the folding boxes 3a are lifted or transferred to the contact pres sure position shown in FIG. 3b. Practically simultaneously the folder plate 11a and the folding fork 14a are moved upwardly. The folder plate 11a presses the blank against the bottom surface of the folding mandrel 2a, while the folding fork 14a moves further upwardly so that the blank is placed against the side surfaces of the folding mandrel 2a. As soon as, however, the folder plate engages the folding mandrel 2a, the folding box 3a moves back again into its starting position. Now the left-hand folding box 3b is lifted and the operation described is repeated on the folding mandrel 2b. Y
  • folding boxes instead of being guided by double levers 4, 5, could also be guided in another manner, for example by means of inclined slide-ways. In such a case, thefolding boxes 3a, 3b would then not bemoved along an arcuate path, but along a rectilinearly inclined path.
  • a bag making apparatus including an intermittently rotating wheel having angularly spaced groups of two spaced parallel folding mandrels said groups of spaced mandrels, upon rotation of said wheel, being movable to an operating station having folding means for supporting and transferring blanks of bag material into contact pressure with said folding mandrels to form a tube-like wrapping
  • said folding members comprise two laterally spaced folding boxes for supporting and transferring two blanks of bag material into contact pressure with respective ones of said mandrels, means for sequentially moving said folding boxes between a feed position in which the bag material is fed thereon and a fold position in which the blanks are in contact pressure with an associated mandrel to fold said blanks, and means mounting said folding members so that the movement of each of said folding members follows an arcuate path between said feeding position and said pressure contact position, said means mounting said folding members comprising a bearing support, a pair of guide levers each pivotally connected at one end to said bearing support and pivotally connected at the other end to said folding boxes,
