Definitions
- This invention relates to a method for producing an end closure for a vacuum cleaner dust bag by manufacturing in a first stage a tube shaped work piece comprising an outer layer and one or several lined layers.
- a seperate sealing piece comprising a layer of a rather non porous but air pervious material, such as the outer layer material of the bag, is glued on the outside of the bottom part or the top part of the bag.
- These sealing pieces are, when they are glued to the outer layer, so flexible that they easily follow the contour of the outside layers.
- the purpose of this invention is to fascilitate the production process by eliminating these sealing operations . This is achieved by means of a method having the characteristics mentioned in the claims.
- FIG. 1 is a perspective view of a bag for which the method according to the invention is used
- Figs. 2-6 are three separate projections of different stages of the manufacturing procedure (where a and c are side views and b are end views)
- Fig. 7 is a perspective view of a part of the bag as shown in Fig. 5.
- Fig. 1 shows the finished dust bag which is produced from a tube shaped work piece having several layers of air pervious material 10.
- the bag has an upper mainly flat top part 11 on which a plate 12 of comparatively stiff material such as cardboard or plastic is fastened.
- the plate 12 as well as the top part 11 has an opening 13 through which a sleeve arranged on the vacuum cleaner is inserted in order to distribute the dirty air into the bag.
- the opening 13 might be provided with an elastic membrane 14 partly covering the opening 13 and forming a seal against the sleeve.
- the bag is also provided with a bottom part 15. At least one of the end parts 11, 15 described above is manufactured in accordance with the principle described below.
- a tube shaped work piece 16 comprises an outer layer 16a and one or several inner lined layers 16b together forming the air pervious material 10.
- the outer layer serves as a fine filter having a larger flow resistance and being tighter than the inner layers who serve as a porous coarse filter.
- the work piece is cut into suitable lengths in order to form the finished bag by successive folding and glueing operations.
- Fig. 2 one end of the cut work piece is shown in the flattened out position the work piece having two opposite, inwardly directed folds 17 extending in the length direction.
- Two recesses 18 and 19 respectively which together form the opening 13 in the finished bag might be provided. If the end is used to form the bottom no recesses are produced.
- the far away side of the work piece according to Fig. 2a is also provided with two cuts 20 extending in the length direction through the outer layer 16a.
- the work piece is then, according to what is shown in Fig. 3, provided with folding lines 21, 22 and 23 resp. thereby forming a rectangular collar shaped part 24 having four wall parts 24a, 24b, 24c and 24d.
- the wall parts 24b and 24d are folded inwardly as appears from Fig. 4 after which one side of the wall part 24a is provided with glue on the areas which do not have any lined layers and is according to what is shown in Fig. 5 is folded inwardly so that it partly covers the two wall parts 24b and 24d and is secured to them.
- the inner lined layer 16b will be folded twice within the triangular areas 25 (Fig.
- the plate 12 might then be applied on the end part whereas the other end of the work piece is closed by the same method or in some other way.
- the advantage with the arrangement according to the invention is that glueing takes place directly between the outer layers at the area 27 which gives a sealed connection without using special sealing pieces or by admitting the glue to penetrate the porous lined material.
