Abstract

The device according to the invention is used for the efficient production of large-area textile structures, such as inflatable halls, tarpaulins and tents. The aim of the invention is to avoid heavy physical work during the production of edge seams and to enable a more rational production with high seam quality. The technical task is to design a corresponding device in such a way that the edge seams are produced in a working process by coordinated movement sequences of the device elements. According to the invention, two sewing machines are arranged at right angles to the sewing direction so as to be movable between two parallel transporting rolls. A transport device can be arranged between the sewing machines. Also expedient is the arrangement of movable in Fuehrungsprofilen connected by straps Ablagestaeben between Naehmaschinen. Fig. 1

Description

a) Title of the invention

Device for producing edge seams on, in particular, curved, large-surface confection products

b ) Field of application of the invention

The invention relates to a device for the rational production of large-scale textlien structures such as air halls, tarpaulins, tents, etc.

c) Characteristic of the known technical solutions

In the production of large canvas seams' and / or ösenleisten are usually after the completion of sewing together of the individual webs at the front ends · For this purpose, the ready-made product must be passed manually past the sewing machine and rotated. At the same time, labor productivity is very low and, in addition, is impaired by the auxiliary personnel required. · Auxiliary work, in particular, requires physically high labor input. Due to the curvature of the web edges, it is very difficult to ensure a high seam quality with this method of operation.

d) The aim of the invention

The aim of the invention is to provide _for an apparatus for making seams on the edge in particular curved large-area Konfektionserzeugnissea avoided in the heavy physical labor and a Rationel IeYe-production is possible at high quality seam ·

e) essence of the invention

Technical object of the invention is _{f to design} a corresponding device so that the edge seams are made in a working process by coordinated movement of the device elements.

According to the invention this object is achieved in that two sewing machines are arranged at right angles to the sewing direction movable between two parallel transport rollers · A transport device can be arranged between the sewing machines ·

Also useful is the arrangement of sliding in guide profiles connected by straps storage bars between the sewing machines.

A z. B · a large confectionery product produced by an upstream clothing plant is placed between the two sewing machines on the transporting device or the transporting rollers. The sewing machines are located on platforms that can be moved between the transport rollers. During the sewing process, the transport device is actuated synchronously. The sewing machines are moved at right angles to the platforms in accordance with the curved path.

The transport rods extending in the guide profiles prevent the web from sagging between the transport rollers. N '

The solution according to the invention avoids the need for any auxiliary forces during the sewing process. The large tarpaulins, 2. 3 of air-inflated halls, are provided with hems / grommets on both front sides in one operation. While the sewing and transport processes are coupled, the sewing machine is continuously B. electromechanical, positioned by the seamstress depending on the seam ·

f) Ausführunqsbeispiel

The invention will be explained in more detail below with reference to an exemplary embodiment. In the accompanying drawings:

FIG. 1 shows the entire device in plan view, FIG.

Fig. 2 shows a mobile sewing machine in side view and

3 shows the arrangement of the storage rods ·

For frontal sewing of hems / Ösenleisten a tarpaulin S, z. B, for an air-inflated hall, past a transport device 1 on the front side arranged in the direction of the longitudinal axis of the transport device 1 movable sewing machines 2 · The conveyor belt consisting of conveyor 1 forms a central part between the sewing machines 2 and is moved by the transport rollers 4. The transport rollers 4 are interrupted in the middle. As a result, only the adjacent half of the transport device 1 is moved by each sewing machine. For larger differences, the still working machine is also switched off. The sewing pedal is coupled to the transport rollers 4 via a switching element 3. Due to the change in length (curvature) of the plane edge, the two sewing machines 2 must

see the transport rollers 4 are moved according to electromechanical · λ

When moving in the direction of the outer end position, the storage rods 6 connected by the belts 5 to the sewing machines 2 are moved between the guide profiles 7. Outside the area of the transport device 1, the storage rods 6 prevent the tarpaulin 8 from sagging.
