Description

Knife for punching out individual parts for items of clothing ie the invention relates to knives (a set) for punching out pieces of clothing (e.g. for front parts, back parts and the like of a jacket) from a large number of layered layers of fabric.

The purpose of the invention is the punching out of individual parts for items of clothing, which are then sewn together to make a jacket or the like, for example.

To cut items for clothing items, one uses Round, sto and band knives. On the top layer of layers of fabric stacked one on top of the other individual parts are drawn and fitted according to the outline (contours) cut out the aforementioned knives. The disadvantage here is that there is no exact cutting out possible.

is.

Knives that are closed in themselves are also known, with knives stacked one on top of the other Punch out layers of fabric. This procedure is relatively simple, but has the disadvantage that for every other shape, every other size and for every other speed a separate, closed knife required. One time is the creation of this knife for one ; 2orm very expensive, because an average of seventy degrees are required. Furthermore but storage is not even conceivable. One therefore helps oneself by being manufactures closed knives for some common boys.

The object of the invention is to create a knife set that largely is suitable for other shapes and other sizes.

The given task is solved. by a plurality of knives according to the respective contours of the item to be manufactured for the items of clothing, i.e. it will be broken down into individual parts to be put together when used Punch knife created according to the basic idea of the invention.

The essential idea of the invention is thus to be seen in the closed, Knife manufactured exactly according to the contours of the individual part to be produced to dissolve, i.e. not only create in partial knife ZU, but extended in at least one direction, so that - starting from the smallest size - Any other size can also be created. According to the respective contours should This means that the knife shape corresponds to the outer boundary - the contour of the individual part. You can use more than one knife for one edge length.

Any breakdown in the appropriate sense is conceivable.

According to a further feature of the invention, at least one esser should be shaped according to the respective (assigned) contour, preferably the largest size of the item.

The invention is further characterized by the feature that all Knives lined up in the correct order according to the respective contours are longer (have a larger circumference) than a known, self-contained one Knife with the same contour.

The procedure is such that the contour of the Individual part on the top layer of fabric e.g.

recorded, then the knives are placed according to the line, and preferably at two approximately opposite one another Contours (but not mandatory), and that the first punching process is then carried out, and that then the knife is placed according to the not yet punched out contours and the last punching operation is carried out; of course you can choose between the first and also further punching processes according to the punching process indicated last invention be interposed.

The invention has the advantage that a saving is achieved Knife costs in the ratio 1: 12 (approximately) is recorded. Now is that too Storage of knives became possible in the first place, and ultimately the bridge punch used for this purpose be lighter, so that these operations can also be carried out in higher floors are feasible.

There is the further advantage that the knife sets according to the invention Can be used for other shapes and other sizes (usually not for other parts).

further details of the invention emerge from the drawing and writing, namely shows: Fig. 1 is a plan view of an individual part (here a front part of a jacket lining) and tig. 2 in section a punch knife in Original size.

When the layers of fabric to be used are stacked, the contours are recorded.

Then, for example, knives 1 and 3 are used, which are a little longer are as needed here.

If you want to punch out another size (larger size), then you can for example knife 1 (knives 1 to 4 are represented by lines) use, places the bulge correctly on the fabric and reached through the greater length (see the overhangs on both sides) that the cut length is sufficient is.

In the following, the knives 2 and 4 are put on and the Stacked layers of fabric are punched out. These knives are also longer as needed; they have, for example, at least the length of a contour corresponding to the largest size.

In Fig. 4 a knife is shown at an angle, the knife steel can be seen 5, to which a knife back plate 6 is attached. Between this so educated Angles are Stabilizing bars 7 are expediently provided, namely at greater distances from each other. The ejector rubber 8, which has two tasks, is glued on has to fulfill, namely the attached knife to bring n standing and after to bring the knife back into its original position after the punching process, i.e. to release the punched layers of fabric.

The individual knives (partial knives) 1 to 4 shown in FIG. 1 can be divided, i.e. the single knife 4 could consist of two or more single knives be manufactured if necessary.

In this context it should also be mentioned that individual knives as shown in Fig. 2 shown in the basic structure are known; but they are used for matched Length for shaping, i.e. for solving another problem; one also needs here only one knife at a time and no sets of knives.

Claims (4)

Claims Knife (set of knives) for punching out individual parts for clothing (e.g. a front part of a jacket) made up of a multitude of layers one on top of the other Fabric layers, characterized by a plurality of knives (1 to 4) accordingly the respective contours of the individual part. 2. Knife (knife set) for punching out individual parts for items of clothing according to claim 1, characterized in that at least one (or some) knives (1 to 4) is shaped according to the respective contour, preferably the larger one Size. 3. Knife (knife set) for punching out individual parts for items of clothing according to at least one of the preceding claims, characterized in that all Knives (1 to 4) lined up in the correct sequence, according to the «respective contours are longer (have a larger circumference) than a known, closed one Knife of the same contour. 4. The method in particular according to claim 1 for punching out individual parts for items of clothing (e.g. a front part of a jacket) from a large number of layers of fabric stacked on top of one another, characterized in that the contours of a E.g. recorded on the top layer of fabric, then the knives accordingly the line are placed, preferably on two approximately opposite one another Contours, and that the first punching process is then carried out, and that afterwards the knives are placed according to the not yet punched out contours and the last punching process is carried out.
