Abstract

For the production of a shoe upper by cutting out of the shoe upper in the form of a layout from a web of material, shaping of the shoe upper with connection of material parts of the layout with formation of seams, a process is used by which such shoe uppers can be produced in a timesaving and efficient manner despite the many individual parts present or to be made visible. For this purpose, a web of material (1) is used to produce layouts (2) by different production measures, such as different styles, yarn material, color, material thickness, single layer or multilayer type of material or the like, at the same time with the production of web of material (1), and with a sole part attached to the layout. The layout is cut from the web as a unit with the sole part and processed into a shoe part having an upper and sole part.

Claims

1. Process for the production of a plurality of shoe shaped parts using a web of material having a plurality of patterns in the form of a layout of a shoe upper thereon, comprising the following process steps:

producing a web of material having an overall construction and having at least portions of patterns thereon which are in the form of layouts of a shoe upper and a sole part, wherein in each layout the shoe upper is directly associated with a sole part by the sole part being attached to the layout in a position of the shoe upper corresponding to an intended location of the sole part relative to the shoe upper in a finished shoe, wherein the layouts of the shoe upper and sole parts are produced by modifying the overall construction of the web of material in the locations of the layouts relative to that in portions thereof where the layouts of the shoe upper and the sole parts are not provided, using one of a different weaving and knitting type for the layouts of the shoe upper than is used for producing the sole parts, said weaving and knitting types being matched to differing requirements for materials of the shoe upper and sole part of a shoe in relation to properties thereof including at least one of the properties of absorptivity, air permeability, softness, extensibility, wear resistance and appearance;

cutting out the layouts from the web of material in a manner leaving the layouts of the shoe upper at least partially connected to the sole parts directly associated therewith as a cut-out unit; and

first stitching parts of the layout of the cut-out unit on provided seams to form an upper of the shoe shaped part, and then fastening the associated sole part of the cut-out unit to an outside edge area of the associated layout by one of stitching and basting.

2. Process according to claim 1, further comprising the step of providing at least one of the layouts of the shoe upper and the sole parts with stiffening means in areas thereof.

3. Process according to claim 1, wherein, during said producing step, the sole part is formed of sole part sections which extend over the entire length of an insole to be formed and which are connected to outside contours of the layout of the shoe upper;

and wherein outside edge portions of the sole part sections are fastened together, by producing a lengthwise seam, to form the sole part

4. Process according to claim 1, wherein, during said producing step, the sole part is formed of forefoot sole part section on one outside contour of the layout of the shoe upper and of a heel sole part section on another outside contour;

and wherein outside edge portions of the sole part sections are fastened together, by producing one of a crosswise, obliquely, and S-shaped seam, to form the sole part.

5. Process according to claim 1, comprising the further step of applying an embroidery at least to the layouts.

6. Process according to claim 5, wherein the embroidery is produced at least partially as English embroidery.

7. Process according to claim 1, further comprising the step of applying one of an insole and a midsole to the sole part after forming of the shoe upper.

8. Process according to claim 1, further comprising the step applying a tongue to the layout by at least one of stitching, gluing and lasting.

9. Process according to claim 8, wherein tongues are produced on a web of material of at least one of different patterns, different types of textiles, colors, and pressures.

10. Process according to claim 9, wherein said tongues are produced on the same web of material as the layouts and sole parts.

11. Process according to claim 10, wherein the tongues are made at least partially in an open space between sections of the layout which later are formed into a heel part of the shoe upper.

12. Process according to claim 10, wherein the tongues are produced on a portion of said web of material which is of at least one of a lower quality, density and weight relative to portions of the web of material on which the layouts are produced.

13. Shoe shaped part produced by the process of claim 10, wherein each layout is produced having at least five patterns of different types of production.

14. Shoe shaped part according to claim 13, wherein each tongue is produced having at least two patterns of different types of production.

15. Shoe shaped part according to claim 14, wherein the sole part has a textile portion made of a material with good moisture-absorbing properties.

16. Shoe shaped part according to claim 15, wherein the material with good moisture-absorbing properties is cotton.

17. Shoe shaped part according to claim 15, wherein the material with good moisture-absorbing properties comprises at least about 25% of the entire material of which the sole part is formed.

18. Shoe shaped part produced by the process of claim 10, wherein each layout is produced having at least five patterns of different types of production.

19. Shoe shaped part according to claim 18, wherein the sole part has a textile portion made of a material with good moisture-absorbing properties.

20. Process according to claim 9, wherein the tongues are produced on a web of material which is of at least one of a lower quality, density and weight relative to the web of material on which the layouts and sole parts are produced.
