Abstract

1. Means for joining two material webs (1, 2) of coated resilient plastics for the production of clothes for water sports, such as surfing suits, sailing suits or the like, the material webs (1, 2) lying one upon the other and being connected at their adjacent marginal zones (3) by means of a seam, characterised in that a serged seam (4) is arranged as a nearly water-tight connection, the tension of the thread being chosen such that a contraction (7) of the marginal zones (3), i.e. a decrease in the thickness of the material webs lying upon one another, is achieved, and that the surfaces of the material webs (1, 2) lying upon one another are the outer side of the clothes when being in the position for use, the contraction (7) formed by means of the serged seam (4) forming as a bent off marginal zone (3) a bead at the inner side of the clothes.

Seam casing for connecting two webs of material

The invention relates to a seam training for Connection of two material webs, preferably made of coated elastic plastic, for the production of clothing, in particular for protective clothing for water sports, such as surf suits, sailing suits or the like.

In the case of connections between material webs of this type, there is the problem of being as watertight and as possible to produce a durable seam. So far, this has not been possible with seams alone. It will therefore the material webs are glued on butt and over an attached tape by means of a four-needle chain stitch seam tied together. This known training with a so-called Mauser seam is relatively expensive because it is additional the gluing process is carried out for the sewing process

must become. It must also be taken into account that the stitch holes required in the seam have a capillary effect cause.

The object of the invention is to create, in a simple manner, an almost watertight seam design for a generic area of application, which can be produced in one operation by sewing and which ensures a connection that can be stressed.

The solution to this problem is according to the invention by the use of an overcasting seam as almost marked waterproof connection.

An embodiment of the invention is created in that the material webs with the · in the finished state outer surfaces lying one on top of the other at their adjacent edge zones by means of an overlock seam are connected and the Uberwendlichnaht with a thread tension to constrict the edge zones is made. This makes it possible to create sealing butting zones that are virtually adjacent to one another to obtain a kink of the outermost edge zones in the position of use of the material webs and the To be arranged as a holding element on the inside.

A specific embodiment is created according to the invention in that in the case of material webs made of coated 3 mm thick neoprene overlock seam with thread tension in the area is made from about 20 to 90 g.

A favorable training is created in that an im between the adjacent edge zones

finished state outwardly protruding piping is arranged from the overcast seam with is captured.

To complete it, it is proposed that the piping has a core thread.

This makes it possible to better drain the water in the area of the seams and, in particular, through the soul thread to bring about a covering of the seam.

Exemplary embodiments of the invention are shown schematically in the drawing. Show it:

1 material webs in the processing position for applying an overcast seam,

Fig. 2 connected webs of material in the position of use and

Fig. 3 connected webs of material

with a piping with a core thread in the position of use.

To connect the material webs 1 and 2, the outer surfaces in the finished state are placed on top of one another and connected on their adjacent edge zones 3 by an overcast seam 4, here the thread tension is chosen so that there is a constriction 5 in the edge zones 3 and thus the opposing joint zones are pressed together to form a seal.

When the material webs 1 and 2 are taken apart in the position of use, the outer edge zones 3, the butt zones virtually forming a bead that is created by the overlock seam 4 is held. The Überwendl ingsnäht 4 lies on the water-protected inside of the formed Garment.

According to FIG. 3, a piping 5 is additionally arranged, which in the edge zones 3 of the material webs 1 and 2 held by the overcasting seam4 will. A core thread 6 covers the actual seam between the material webs lind provides additional protection.
