DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. FIeld of the Invention
This invention relates to a method of manufacturing a pocket construction provided with a welt, which comprises
a pocket pouch with an inner panel and an outer panel, whereby the outer panel is closer to a garment,
a slot provided by forming a slit through the garment and the outer pocket panel, the ends thereof being formed into the shape of a V, and by folding the edges of the slot on the outer pocket panel, and
a lower welt partially on the pocket slot and partially on the lower edge of the pocket slot, and is attached by a stitch.
2. Description of the Prior Art
Pocket constructions provided with a welt as described above are very generally used especially as trousers back pockets and jacket side pockets. They are then mostly provided except with a lower welt also with an upper welt or a flap and possibly also a link. A manufacture of such a conventional pocket construction with a welt, which has proved to be good and durable in practice, is, however, difficult and requires many steps including for example the step of turning the pocket pouch with the welts through the slot. An automation of such a process is understandably very complicated and has so far not been possible.
As efforts at manufacturing welt pockets automatically can be mentioned the methods known from U.S. Pat. Nos. 4,315,793 and 4,263,678. The apparatus described in U.S. Pat. No. 4,315,793 is, however, not automatic, but requires a manual removal of a pocket blank from one device unit to another. In the method described in this publication, the welt pocket construction has been simplified and it includes hardly any seams made by sewing, but the seams are manufactured mainly by means of an adhesive technique. This results in that the pocket slot is stiff, and on the other hand, tears easily. A welt pocket construction assembled in a similar manner, i.e. exclusively by adhesive attachment, and reinforced by some stitches only is known from U.S. Pat. No. 4,263,678. The advantage of this construction is that it can be assembled entirely on the reverse side of the garment, but it has also the drawbacks of the above-mentioned constructions attached by adhesive.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a new method of manufacturing a conventional welt pocket construction proved to be good, which method is of that nature that it enables a considerably simpler realization of an automatic production line than would be possible when using a conventional method of manufacturing welt pockets. The most essential feature of the method is that it is at no stage of operation necessary to turn the pocket pouch through the pocket slot, and according to the invention, the manufacture of the pocket pouch can entirely take place with the same side of the garment out, which makes it unnecessary to turn the garment, which would complicate the automation. The accomplished welt pocket construction does not, however, differ from the welt pocket construction found to be good in this field.
This object has been reached by means of the method of the invention:
at the ends of a pocket slot are punched V-shaped slits through both the outer pocket pouch panel and the garment, the points of the slits pointing at each other,
the triangular points formed by the slits mentioned are folded on the outer pocket pouch panel,
the triangular points mentioned are secured in their folded position and simultaneously, the garment and the outer pocket pouch panel are secured to each other within the area of these points,
the pocket slot is cut open and the edges of the slot are folded from the level of the garment on the outer pocket pouch panel,
the lower welt is brought partially on the pocket slot and partially on the lower edge thereof and is secured to this lower edge by means of a stitch, and
the inner pocket pouch panel is placed on the outer pocket pouch panel and secured thereto by means of a stitch to form the pocket pouch.
As the most preferable alternative, though not the only alt
