DE3140533C2 - Cut-to-size parts made from upper and lining material to form a finished bag-making item - Google Patents

Abstract

To reduce the total number of leather blanks for small bags, such as purses, wallets and the like, blanks are used in particular in the plan dimension of the finished bag with cuts limited within the cut part, which are essentially linear to form a slot-like passage to a compartment, or which are essentially linear to form a fold-out one Are cut at an angle. For example, the finished bag-making item according to FIG. 1 is formed from the leather blanks (1 to 4) and the lining blanks (5 to 8). The essence of the invention lies in part 2, each of which incisions (9) can be spread to form a compartment for the passage. The leather blanks are made under extensive pressure that avoids distortion of the material in a single operation that includes the contour-shaping punching or re-punching, the cutting of the incisions (9) and the embossing of imitated stitching (17) and of Reifelstrichen (18) includes, made to fit. The accuracy of fit and the small total number of leather cuttings allow the completion of a flawless, fine finished handbag item with open edges that cannot be reworked.

Description

The invention relates to cut parts made of upper and lining material for the formation of a finished handbag item, in particular made of leather, such as purses, wallets, combination purses (purse and wallet), neck pouches and similar articles.

The invention aims on the one hand to facilitate the professional craftsmanship of the Finished products of the type mentioned, on the other hand, it particularly aims at the private consumer Cut-to-size parts for self-production without specialist knowledge and skills of fine bag-making goods of the outline genre at hand.

For self-production, cut-to-size parts are simple, unlined and comparatively tough LCD pouches are known to meet aesthetic needs in terms of appearance for fine leather goods however, cannot satisfy, especially not because of the intended way of sewing the seams pre-punched lcdertcilc in the wrong Saulerstich with a very strong thread or with a plastic rod Leather cord.

Cut-to-size parts for making such finer ones Leather bag-making goods with extensive subdivision into compartments or pockets, which when carefully ■ bau finished products manufactured by skilled workers are not known.

Fine leather goods are not only characterized by the quality of the leather but also by the care taken Processing from, whereby on the cleanliness of the edges or the joint of edges of the finished goods special value is to be attached.

For the conventional, professional production of fine handbag goods, the for Finished leather items to be assembled first mechanically with a normal punching knife punched out and then »sharpened» at the edges d. H. made thinner at the edges towards the edge step-shaped or wedge-shaped, in order to be later

J (I Quilting of the leather parts with one another to avoid a bulge in the edge. The mechanical stress on the leather during punching and sharpening regularly leads to slight distortions of the blanks, so that they have to be reworked, e.g. re-cut or re-ground, for exact adaptation to each other either before or after their assembly (by machine quilting), for which a specialist and Specialist equipment is required. Special care requires clean production "o ^r fenkantig" goods exported, which is why the vast majority of the designated fine leather goods "" taken are working. Furthermore, it applies to the conventional construction that the more individual leather parts have to be assembled, the more diverse the finished piece is to be divided into pockets or compartments. Finally, collapsible articles, e.g. B. wallets and purses, conventional design for tension-free folding on a continuous leather outer part (blanket), which is larger than the plan of the stretched out article, but which is compressed to the floor plan with the inner parts to be sewn so that in the area of the break an outwardly protruding fold is formed to compensate for tension when it is folded up. A skilled worker is essential for this production process too.

The object of the invention is thus to simplify the production of fine handbag goods from their Individual parts to a level of requirements for the manufacturer of the goods, which is also briefly semi-skilled, yes even anyone can assemble it into a flawless finished piece.

In the case of blank parts of the generic type, this object is achieved by the characterizing features of claim 1. By reducing the number of items to be joined together while maintaining the wealth of designs of a comparable conventionally manufactured piece and by precisely cutting the individual leather parts to be quilted, reworking of the finished piece is no longer necessary.

The reduction in the number of individual leather parts is surprisingly simple and useful achieved by the fact that instead of a series staggered over or individual parts to be placed together and sewn together at the edges, only one incised only part is provided, the limited incisions of which engage the pockets or Form subjects, for their full training additional parts such. B. from lining, in the same Arrangement as in the conventional construction of the finished piece to serve.

For the accuracy of fit of the leather blanks, the leather is closed and under the action of a press ram cut, which avoids distortion of the leather when it is cut and / or punched.

Further developments of the invention are given in the subclaims.

For a more detailed explanation of the invention - purely exemplary - figures used. It shows

Fig. 1 in perspective representations of a wallet as a finished piece and in plan view all of its components, d. H. a full set of blanks according to the invention;

Fig. 2 is a perspective view of a cut leather cut according to the invention as Semi-finished part, namely the inner part of a combination exchange with an indication of "opened" intervening

open the door.

1 in the top row of figures on the left folded from the outside and unfolded on the right from the inside is made up of the leather blanks or parts 1 to 4 and from the leather blanks or parts 5 to 8 . B. from non-fraying impregnated lining, assembled. Parts 1 to 8 are to scale among themselves. The leather parts I ₁ 3 and 4 and the lining parts 5 to 8 are essentially conventional. The essence of the invention lies in the leather part 2 and in particular in its incisions 9, which are each limited here at their ends. Strips or sections 10 to 15 are formed by these incisions. Part 1. the outer part or the ceiling, and part 2, the inner part, are congruent with each other, but with the exception of the recess 16 of the inner part 2. Parts 3 and 4 are intended for the formation of the coin compartment.

For the rough shaping, the cut pieces 1 to 4 are first - conventionally - punched out of the skin with a punching knife on a conventional punching machine. The exact shaping and preparation of the functionally finished and precisely fitting piece is then carried out in one operation using a special tool, in which the raw blank is simultaneously trimmed and, if provided, incised and imitated quilting seams 17 and, if necessary, marking lines 18 are embossed. Sharpening can be dispensed with. By means of the special tool, _{I have the leather blanks} punched out of the skin with simultaneous cutting and / or embossing of imitation quilted seams and stripes, also directly to fit. As a result of the surface-covering pressure applied, the required accuracy of the _J5 outline form or the edges and the incisions is produced or maintained. Cutting under pressure is a method known in the art. The imitated quilting seams 17 indicate the position of the later seam or the later seams for the assembled finished product, denote the reifel lines 18 and facilitate the later breaking of folds of the leather part; Reifel lines 18 along cut or cut edges (not shown in FIG. 1; see, however, FIG. 2) at the same time solidify the leather material and prevent "softening" of the edges when the finished product is used; they also have an aesthetic effect.

In order to assemble the individual parts prepared in this way into a perfect finished piece, a (household) sewing machine and glue are required. For example, the finished article according to FIG. 1 is to be manufactured in the following production stages (the location information relates to the positions shown in FIG. 1):
On the back of the inner part 2

55

1. Glue the lining part 8 with its upper edge onto the lower • half of the strip 13 and the rest of it

Glue the edges flush with section 14; _b0

2. Glue the lining part 7 with its upper edge along the upper edge of the strip 13, facing outwards fold over and glue the lower edge to the lower half of the strip 12 (sack);

3. Lining part 6 with its upper edge along the common edge of the strip 12 and the Glue on section 15 and glue the remaining edges on butt.

4. 18 folds on leather part 4 along the reifel lines break and knock this, the folded part 4 at its edges on the side and below on the leather part! 2 (Section 5) and stitch on the left edge of the part of the pocket 4. then the parallel to this, the second Miltensteg of the Ledeneils 2 quilting;

5. Glue leather part 3 / with its upper edge onto leather part 2 (section 5), stitch in place and sew the seam continue along the upper edge of the section 12 to the left outer edge of the leather part 2;

6. Glue the lining part 5 with the common upper edge behind strip 11 and attach the remaining edges Bring push and glue;

7. Bring leather part 1 with the previous arrangement and glue it to the edges;

8. Quilt the border and finish with it.

The left compartment part of the finished product has a perfectly flat inner surface and its edges are not made up of more than two leather layers at any point, as there are no overlapping leather parts (such as occurring in the previous construction) are arranged. Because of the relief recess 16 in the leather inner part 2, the prefabricated piece can also be folded up almost without tension, so that the ceiling or the leather outer part 1, in contrast to the conventional design, cannot be processed in a compressed manner.

This bill pocket now shows - in consideration of the surfaces adjacent to the inserted objects - on: a banknote compartment, formed from the leather part 1 and the strip 10 at the back and the fabric part 5 at the front; another bill compartment, formed from the sofa part 3 and the strip 11 at the back and the fabric part 6 at the front; a pocket (z. B. for a check card), formed from the fabric part 7 turned into a sack and from the Strip 12 at the back; another pocket, formed from the fabric part 8 and the strip 13 at the back and the Section 14 front; and the coin compartment, for which a lock, e.g. B. a snap fastener, can be provided.

Apart from the conventionally built coin compartment, this bill pocket requires according to the Invention of only two leather cuts. A conventional bill pocket with the same functions would also worked with open edges, but require six individual leather cuts; the ceiling that owes the compression fold along the break, however, would be larger than the plan of the pocket would have to be cut, one of the integrated strip 10 corresponding independent glare strips; one of the integrated strips U corresponding independent and advantageously wider engagement strips; one of the area coverage of the integrated strips 12 and 13 and the integrated sections 14 and 15 corresponding inner part (without Recess 16), an independent and advantageous corresponding to the strip 13 placed thereon wider engagement strips and one that is in turn placed on, or possibly attached, the integrated one Section 14 corresponding independent part; even in the struck version, for the one There would be no separate cover strip if five instead of two individual leather parts were required.

Because of the larger number and width of the individual parts for conventionally built bag-making goods this results in a higher demand for leather and, at the same time, a larger waste. These disadvantages will also be through the cuts according to the FrfinHnno vprmioHon

Fig. 2 shows an again one-piece inner part with integrated strips or transcripts according to the invention. A new incision variant is shown, by not only in more or less only one surface direction incisions 9 for engagement slots 19 now also surface-delimiting over two Incisions 20 guided in spatial directions are provided, which allow sections 21, 22 allow without a fold-out independent item would have to be arranged.

This shown blank of an inner part of a combination purse also has a complete one Cutout, a window 23 of the fold-out section 21, which is covered with a transparent film can be deposited to form a visual compartment. The return ropes can also be made with a similar film of section 21 and the top view of the corresponding "frame part" to form a compartment for Recording z. B. a document of a length that is about twice the height extension of the part 21 matter, deposit. By stitching side gussets and stitching an upper flap, the Section 22 a coin compartment, which by means of a

Push button, one half part 24 of which is already arranged on section 22, closed can be.

The imitated quilting seams 17 and tread marks 18 are also shown. As a finished product, the the illustrated inner part made combination exchange have a this underlaid cover that on three edges is quilted; is the ceiling with Stauchfalic formed along the break 24, the inner part does not require a recess 16.

With regard to the within the area of the blank Finally, with limited incision, the invention is not limited to leather as the upper material; even Imitation leather and other upper materials customary in the field of bag-making can be found in the described Manner, including the embossing of imitation stitching as a symbol for the Arrangement of the final quilting seam for the finished bag-making item and of ripening lines for Facilitating the breaking of folds or for reasons of strengthening incision, cut-out or cut edges.
