Definitions

  • the present invention relates to the field of the manufacture of bags, in particular with coating of synthetic material, and relates to a method of manufacturing a bag with coating of expanded PVC, in particular a schoolbag.
  • the present invention aims to overcome these drawbacks.
  • a process for manufacturing a bag with synthetic material covering in particular a satchel, characterized in that it essentially consists in gluing on a cardboard plate a sheet of expanded synthetic material and to carry out by stamping a flat cutout of the bag body with simultaneous printing of the fold lines between the different parts, to optionally carry out, separately, by stamping, a cutout of a pouch to be pressed in expanded synthetic material with simultaneous printing of its fold lines by high frequency welding, then welding the adjacent ends of the free edges of this cut therebetween and providing the pouch obtained, at its upper part, simultaneously, by sewing a decorative strip of synthetic material, and with a zipper extending inside said strip, to provide the part of the cutout corresponding to the front face of the bag, by welding, on each line of folding between this part and the corresponding side parts of a decorative strip of synthetic material, and, where appropriate, near its fold line with the bottom part, of the pocket to be plated, to simultaneously carry out a welding operation two decorative plastic strips on the fold lines between
  • the method of manufacturing a bag with plastic coating in particular a satchel, consists essentially to glue a sheet 2 of expanded synthetic material onto a cardboard plate 1, then to stamp the assembly obtained in order to cut the bag body flat, a simultaneous printing of fold lines 3 being carried out between the different parts of said body ( Figure 2).
  • the printing of the fold lines 3 is carried out by means of a hollow tool having two parallel edges intended to crush the cardboard assembly 1 - sheet 2 during the stamping along the separation lines between the various parts of the bag , and thus favor their folding down along said lines to constitute the body of the bag.
  • a flat pocket 4 can be produced separately, also by stamping a cut out of expanded synthetic material, with simultaneous printing of its fold lines 5 by high frequency welding. The free edges of the pocket cutout obtained are then connected by their adjacent ends by welding, and the resulting pocket blank is simultaneously provided at its upper part with a decorative strip 6 of synthetic material sewn together with a zipper. 7 which extends inside the strip 6.
  • the part of the cutout which corresponds to the front face of the bag is then provided by welding, on each fold line 3 between it and the corresponding side parts with a decorative strip 8 of synthetic material.
  • This front face can, moreover, be provided, according to the desired embodiment of the bag, near its fold line 3 with the bottom part, of the pocket to be pressed 4, the welding of this pocket being then carried out simultaneously with that of the strips 8.
  • strips 8 identical are also welded simultaneously with the first on the fold lines between the part corresponding to the rear face of the bag and the corresponding side parts, just as a back padding 9 is welded near the fold line 3 with the bottom part.
  • the front face of the cutout is then provided with female clasp elements 10 by stapling or by riveting, and the bottom part is provided by riveting hooking elements 15 for carrying straps and the free ends of the cutout , which correspond to the opening of the bag, are provided by sewing with a protective strip 11.
  • the cutout is then ready to be assembled by folding along the lines 3, the free edges of the parts on each side being interconnected by introduction into grooves of an H-shaped element 12 made of synthetic material. At their lower part, the edge parts have protruding tabs 13 which are folded down after folding under the bottom part.
  • Protective elements 14 are then put in place, on the one hand, at the level of the opening of the bag on the sides, and slightly astride the front and rear faces, and, on the other hand, along the sides , on the bottom corners of the bag and on the tabs 13, by riveting or by welding.
  • a flap 16 is produced by gluing on the internal and external faces of an intermediate element of a sheet of expanded synthetic material, then by marking fold lines 17 by high frequency welding, the flap 16 then being provided by sewing with a protective strip 18.
  • the flap 16 On the flap thus obtained are mounted by riveting a carrying handle 19 as well as male clasp elements 20. Then, the flap 16 is fixed to the upper edge of the rear face of the bag by riveting, a suspension handle 21 and a hooking loop 22 for carrying straps 23 being fixed simultaneously on said rear part together with the flap 16.
  • a badge 24 in the form of a mark or decoration is applied by welding to said pocket.
  • Another escutcheon 25 can also be fixed, simultaneously with the marking by welding of the fold lines 17 of the flap 16 on said flap 16.
  • the expanded synthetic material forming the sheet 2 for covering the carton 1 as well as the pocket 4 to be attached and the internal and external faces of the flap 16 is advantageously polyvinyl chloride.
  • the lower protective elements 14 preferably have studs 26 for supporting the ground. These studs 26 allow good support of the bag on the ground without risk of overturning and effective protection of the fastening elements 15.
