DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an arrangement for production of sections cut out from a material web, such as sections for articles of clothing.
In the manufacture of articles of clothing in the clothing industry, work is essentially carried out in a cycle involving the following steps:
1. Determining the configuration of the cloth sections for the garments which are to be produced; thus the pattern work, which results in a number of garment sections for different sizes of different designs.
2. Positioning the pattern sections on a cloth web, with account being taken of the following factors correct side of the garment section in relation to its position in the garment (many garment sections occur twice in the same configuration, but in right and left design) relation to the structure of the cloth (such as its thread direction, in order for the desired lie to be achieved). pattern matching, they are placed on the pattern of the cloth according to the pattern matching. patterned cloths, also c, an as economic as possible positioning of the garment sections on the cloth web should be achieved; thus, they will be set out together in such a way that the intermediate spaces, which constitute the cloth wastage, have as small a surface area as possible. In this connection the best result can often be obtained by the sections of several garments being mixed with each other along the cloth web or even being mixed with garment sections of another size or of another garment design. A mixing, along a defined stretch of the cloth web, of garment sections from several garments thus very often gives a better yield than is achieved by placing all the garment sections of one garment along a defined stretch of the cloth web. However, no further improved effect is obtained, in terms of the wastage, if garment sections are mixed from more garments than a certain optimum number. In addition, a mixing along an excessively long stretch is difficult to monitor.
3. Cutting the garment sections out in the predetermined position.
4. Gathering together, into a set, all the garment sections which are to be sewn together.
5. Sewing together of the garment sections.
It is of course desired that the said operations and the necessary transport work associated therewith should be carried out as efficiently as possible by mechanical means.
Prior art:
As regards the preparatory stages, patent publication GB 2,129,282 discloses data programming of the configurations of the various garment sections in a cutting apparatus which operates with an automatic cutter. Thus, in this connection, the garment sections are cut out from a cloth web and can thereafter be gathered together into the sets.
How the garment sections are to be positioned on the cloth web is determined manually, but it is known to use computer support in this respect. This means that, by simulation on a display screen, it is possible to position the garment sections on the cloth web, after which the computer provides information on what degree of utilization of the cloth has been achieved, and thereafter a rearrangement can be carried out manually etc with successive adjustment to a suitable degree of utilization of the cloth.
The computer program then controls both the shape of the cutting contours and their position on the cloth web.
Thus, the garment sections are cut out after the shape of the garment sections has been determined and programmed in a computer device, and also, thereafter, their position in relation to each other on the cloth web.
The cutting-out itself can be carried out as in the installations for mechanical implementation known from U.S. Pat. Nos. 1,136,048 and 3,572,202, by means of several layers of cloth being laid one upon the other, after which a cutting member is passed through all the layers In this way a number of identical sections are obtained, and such an installation is thus designed for series production of a number of identical garments. The cloth web is laid out , as is also known, on a cutting table by means of a
