DE1129812B - Device for producing shoulder pads - Google Patents

Description

The invention relates to a device for serial sewing, stapling or welding of molded parts, which are at least partially made of multi-layer textile material or plastic and preferably a filler, e.g. B. also foam exist. In particular is the new device intended for the manufacture of shoulder pads.

In the production of such molded parts, so z. B. shoulder pads, as is well known, one must be made textile material or plastic consisting of upper and lower cover layers together with filling layers, Art foam or the like. Be sewn.

Shoulder pads and molded parts of this type have hitherto been manufactured exclusively by hand, i. h., the Shoulder pads were used both for quilting the individual cover layers and for sewing these cover layers are guided by hand in the area of the needle of a machine and in this way sewn or quilted. This production method is not only in view of the high wage share expensive to manufacture, but the individual upholstery or molded parts are at least individual slightly different.

It is known, for the production of certain patterns on workpieces to be sewn, to clamp the workpieces in a carriage and to move them clamped by the carriage in the area of the needle that the desired pattern is created on the workpiece. The invention is based on the knowledge that such a mode of operation can in principle also be used for the production of shoulder pads or similar molded parts. The use of this working principle in the manufacture of shoulder pads means that the parts to be sewn together are clamped in a holding device with which they are moved in the area of the needle of the sewing machine or the welding device of a welding machine. According to the invention, this holding device for the parts to be sewn is designed in such a way that the sewing material is curved at least with regard to a surface extension. Furthermore, the holding device is mounted in such a way that it can be pivoted about an axis lying parallel to the sewing plane in such a way that the curved sewing material is rolled off in the area of the sewing needle on the sewing plane.

According to a further development of the inventive concept, this holding device is then on known control means for automatic and common rotary movement and longitudinal movement the holding device moves.

The device according to the invention can e.g.

for the production of spherical moldings, as they are, for. B. approximated shoulder pads in raglan cut represent, can also be realized in such a way that the insert shell itself is designed as a spherical shell and is accordingly pivoted about two mutually perpendicular axes so that the plane of proximity in every position of the insert shell tangential to the spherical surface, i.e. to that through the sewing material formed areas come to rest. In this case too, the sewing or welding device every single point of the sewing material by swiveling the tray in two dimensions can be achieved.

Together with the new manufacturing device, a automatic control is used, so that by the forced guidance of each seam to be produced Uniform shoulder pad that is no longer dependent on the individuality of the operator arises. About the automatic guidance of the shoulder pad to be sewn in the area of the sewing needle to be able to achieve with simple control processes, as will be explained in detail, are one pivotable tray and a slide provided, the tray in a completely new way be pivoted about an axis running parallel to the plane of movement of the slide can.

It is known per se to clamp the material to be sewn in a holding device in sewing machines and to move together with the holding device in the needle area. In the known institutions takes place however, there is no pivoting movement about an axis perpendicular to the needle axis.
