DE3232941C2 - Method for connecting the end area to a new starting area of a filling material made of wadding - Google Patents

Abstract

In order to connect the end area with the beginning area of a stocked filled filling material for the pipes of an upholstery cover, it is proposed to place the end area of the almost used cotton sheet and the starting area of the new cotton sheet flush on top of one another and to make holes outside of the later longitudinal seam. In the extended position of both cotton sheets, these temporarily connecting fastening parts, e.g. in the form of cable ties, are then pulled into the holes of the two cotton sheets that are assigned to one another. After passing through a multi-needle sewing machine, the connection area is separated again by a double cut.

Description

The invention relates to a method for connecting the end area to a new starting area of a Filling material consisting of wadding according to the preamble of claim 1.

From DE-O3 32 12 570 it is already known in the production of a whistled upholstery cover the required sub-materials as strips of Peel off the rolls and use a multi-needle sewing machine to sew the outer fabric blanks To connect sub-materials. With this largely mechanized production method, the Ask how the end of the respective path section is connected to the beginning of a new path can be that a trouble-free continuous operation is made possible.

The preferred pipe filling material is due to its air-permeable properties The upholstery wadding used has difficulties, as this material is due to its relatively low compressibility not sewn together, such as B. nettle, can be passed through the system in two layers. Also a butt gluing, as it is, for. B. is possible with foam, is ruled out because the bond is only on the outer fibers are limited and these are separated from the adjacent ones during the material pull-through Loosen fibers. Suturing the butt joint areas has turned out to be unsatisfactory, because the workload is too great and the workflow is interrupted for too long.

It is the object of the invention to create a durable connection between the areas mentioned can be produced quickly and inexpensively, with operational disruptions during the passage of the

Association are excluded by the system.

This object is achieved by the characterizing features of claim 1

Multiple use of the fastening part is possible if it is designed as a cable strap

The subject of the application is explained in more detail below with the aid of an exemplary embodiment shown in the drawing

F i g. 1 is a simplified production process of an upholstery cover with a device for Filling material perforation and

F i g. 2 shows a plan view of a start and end area of a cable straps held together Cotton wool pad.

According to FIG. 1 are used for the manufacture of upholstery covers 1 required sub-materials such as nettle 2 and moltoprene 3 each from a roll 4 or 5 withdrawn, while in addition to moltoprene 3 used as filling material for the pipes, 6 a container 7 is removed. The web of Moltopren 3 and 6 wadding is brought together and the wadding 8 through a cutting device 9 lengthwise into individual pieces, divided into strips corresponding to the number of pipes

Before reaching the table top 10, the Nesselbahn 11 is under the sheet of Moltopren 3 and Wadding 6 out An operator 12 successively places outer fabric blanks 13 on, following a feed path is connected to the underlying webs by means of a multi-needle sewing machine 14. By means of a downstream separating device 15, the sewn workpieces are each cut between the outer fabric 13 separated from each other and then stacked

When the lap 8 comes to an end, its end area 16 and the beginning area 17 become the following Cotton web 18 placed flush on top of one another and guided under the multiple star pel 19 of a hole device 20 This provides the two webs with spaced apart areas outside of the later course of the seam Holes 21, as indicated in Fig. 2 is off This figure also shows that <i "<ß in the extended position of the cotton sheets 8 and 18 in assigned holes 21 each have a fastening part 22 in the form of an easy-to-assemble and removable cable tape 23 is pulled in. About this multiple cable tape arrangement, the Wadding web 18 pulled effortlessly through the system until by means of the separating device 15 the so created, between two outer fabric blanks 13 lying connection area separated in the course of a double cut will. The cable straps 29 can now be dismantled and reused.

Claims (2)

Patent claims: 1. Method of connecting the end area with a new starting area of an existing one made of cotton wool Filling material for the whistle; an upholstery cover, the necessary sub-materials for its manufacture be supplied in stock and the web created in this way with individual, successive Outer fabric blanks is occupied, whereupon the individual layers are joined by means of a Multi-needle sewing machine and finally a separation between the outer fabric blanks takes place, characterized in that the end region (16) of the almost used up wad of cotton wool (8) and the starting area (17) of the new wadding web (18) placed flush on top of one another and with a distance holes (21) arranged outside of the later seam path are provided, that in the stretching position of the two cotton wool webs (8, IS) in the respective, mutually associated holes (21) of the two cotton swabs (8, 18) temporarily connecting them Fastening parts (22) are drawn in, and that the created in this way, not through an outer fabric blank (13) Covered connection area after passing through the multi-needle sewing machine (14) is separated by a double cut. 2. Fastening part for use in the method according to claim 1, characterized in that this is designed as a cable strap (23)
