DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention is concerned with a method of making belt loops and subsequently attaching them to articles of clothing, comprising the steps of cutting lengths of textile material from a strip thereof and sewing each such length to an article of clothing, the arrangement being such that, in the finished article, the ends of each length are each folded over and sewn directly to the article, wherein the ends of each length are provided with a coating of a fray-prevention binding medium prior to being sewn, and apparatus for carrying out such method.
BACKGROUND OF THE INVENTION
There is disclosed in GB-A No. 1338706 a belt loop for attachment to an article of clothing, which belt loop has, at opposite ends thereof, a coating of a fray-prevention binding medium.
In manufacturing such belt loops, the loops are first cut from a strip or length of material and then the adhesive material (or binding medium) is sprayed or applied by an applicator to the ends of the loops, or alternatively the ends are dipped into the adhesive for the desired extent or penetration. Although not specifically referred to in said specification, it has been conventional for many years to secure belt loops to articles of clothing by sewing, and indeed more specifically by a method generally as set out in the preceding paragraph.
It will be appreciated that such a method of applying the binding medium requires individual handling of the separate loops, which, if carried out by hand, is tedious and time-consuming or, if carried out by machine, requires relatively complicated handling apparatus. Furthermore, since the adhesive has then to be dried prior to attaching to the article of clothing, further handling steps, and possibly storage for a short period, are required.
Thus, the method set out in GB-A No. 1338706 does not readily lend itself to a production line, still less to an automatic production of garments.
It is proposed in FR-A No. 2329787 to apply locally, e.g. by a screen printing technique, a binding medium to sheet material, e.g. textile material, prior to cutting into garment components, with a view to the binding medium subsequently preventing fraying of the edges of such cut components. In this case, however, the cut edge portions are not to be exposed in the finished garment (bearing in mind that the edge treatment is intended merely to replace a conventional overlocking of otherwise raw edges), so that from the point of view of the appearance of the edge portions in the finished garment it would not be considered important to ensure that no loose thread whatsoever could arise. Consequently for example it was considered adequate to apply the binding medium only to one side of the material.
By comparison, belt loops are clearly visible in the finished garment, so that even a small number of loose threads will not be acceptable. Furthermore the effectiveness of the fray-prevention should last for an extended period, viz. throughout the life of the garment, even when subjected to repeated washing.
OBJECTS OF THE INVENTION
It is thus one of the objects of the present invention to provide a method of making belt loops and attaching them to articles of clothing, which method, while on the one hand enhancing the appearance of the finished garment and preventing any unsightly fraying of the belt loops thereof, also on the other hand lends itself to automated production line manufacture.
It is another of the objects of the present invention to provide an improved apparatus suitable for use in carrying out a method in accordance with the invention, which apparatus facilitates automated production.
BRIEF STATEMENT OF THE INVENTION
The first of the above objects is resolved in accordance with the invention, in a method as set out in the first paragraph above, in that, prior to cutting the lengths from the strip material, the binding medium is applied to both sides of the strip material in the form of stripes which extend transversely of the strip material and are spaced apart by a distance corresponding to
