DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a method for attaching ready-made pieces of material, particularly collars, cuffs, button and buttonhole tapes and other trimmings to a further piece of material, the ready-made piece of material being made from at least two material portions and is ready to be attached, a selvedge of the further piece of material then being connected to the ready-made piece of material.
BACKGROUND OF THE INVENTION
In the clothing industry, parts such as shirt, blouse and clothing collars, cuffs, button and buttonhole tapes, etc are made in separate operations and are subsequently attached by means of further operations. A relatively large number of operations cannot be avoided, so that the expenditure is relatively high. It is particularly difficult to sew the open selvedge of the ready-made piece to the selvedge of another piece of material and it must therefore be carefully performed by trained personnel.
SUMMARY OF THE INVENTION
The problem of the invention is to so develop a method of the aforementioned type that the number of sewing processes are reduced and these processes can be performed without careful matching of the parts to be sewn.
According to the invention, this problem is solved in that selvedges of the parts of the ready-made piece of material which are to be sewn together with the further piece of material are bent round in opposite directions, folded and fixed in the folded state.
The invention also covers an apparatus for performing the method according to the invention having guide means for guiding the piece of material, folding means for folding the selvedges of the parts of the ready-made piece of material, supply means for supplying an adhesive to the vicinity of the folding means and fixing means for fixing the folded selvedges.
Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
The invention is described in greater detail hereinafter relative to two embodiments shown in the drawings, wherein represent:
FIGS. 1a-e the attaching of a shirt collar in diagrammatically represented cross-sections of FIGS. 1a-d and its sewing to the shirting in a diagrammatically represented cross-section of FIG. 1e according to the prior art.
FIGS. 2a-c the attaching of a shirt collar and its sewing to the shirting in diagrammatically represented cross-sections.
FIG. 3 a block diagram of an apparatus for preparing a ready-made piece of material for attachment to a further piece of material.
FIG. 4 a diagrammatic view of the apparatus of FIG. 3.
FIG. 5 a section along line V--V of FIG. 4.
FIGS. 6a-g the attaching of a further, partly shown shirt collar up to the fixing of the selvedges provided for sewing to the shirting in diagrammatically represented cross-sections.
FIG. 7 a diagrammatic view of a further apparatus for preparing a ready-made piece of material for attachment to a further piece of material .
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
According to the prior art shown in FIGS. 1a-e, for attaching a shirt collar, initially an insert E of random design is joined to an outer layer of material 01. According to FIGS. 1a-e, insert E can be formed from insert parts. However, it is also possible to stiffen to a varying degree by means of a stiffener at different points the said insert E. However, the design of insert E is unimportant. After joining insert E and the outer layer of material 01, the material which projects downwards by about 6 to 12 mm is wrapped around the lower edge of the insert and sewn by a seam 1 (cf FIG. 1a).
According to (b) a lower layer of material 02 is placed on the outer layer 01 and the collar is presewn with a seam 2. According to FIG. 1c, the presewn collar is then turned and after turning is stitched by a seam 3. According to FIG. 1d, the open selvedge S of material 02 of the underside of the collar is sewn by a seam 4 to shirtin
