Problems solved by technology

Therefore, unless the orientation and spacing of the stitches correspond exactly to the existing perforation lines, which is actually unlikely, and even difficult to do, the stitches will tend to travel meandering between the existing perforations, thereby destroying the completed Aesthetic Effects of Seamed Materials

Embodiment Construction

[0020] Figure 1 shows a sheet 1 of perforated leather of the prior art, in which stitch threads 2 penetrate the material. The material 1 is perforated in a regular pattern of perforations evenly spaced on parallel spaced straight lines. By using a conventional sewing machine, a stitch line 2 through the material is formed. The stitches tend to bend and travel between perforations in the material. Therefore, the stitch line is not smooth or straight, and this spoils the appearance of the stitched material.

[0021] See now figure 2 with image 3 The method according to the invention involves supplying a sheet 3 of material, in this case leather, which has one or more perforated areas 4 separated by non-perforated areas 5. In this embodiment, each perforation area is substantially diamond-shaped, formed by a series of parallel and evenly spaced perforation lines. The unperforated area 5 includes a strip of unperforated material extending between the perforated areas to form a di...

Abstract

A method of producing a stitched perforated sheet material including providing a sheet material (3) with a perforated region 4 and an unperforated region (5). The sheet material is then stitched in the unperforated region, but adjacent to the perforated region. This gives an overall perforated appearance whilst avoiding the problems associated with stitching through a perforated material.

Description

Technical field [0001] The invention relates to a method for processing stitched perforated sheet material. The present invention particularly relates, but not limited to, interior decoration and interior decoration for vehicle seats. Background technique [0002] Perforated leather and similar materials are widely used in interior decoration, especially in the interior decoration of automobile seats. Perforations provide the desired decorative effect and can be used to create decorative patterns. It also allows air to pass through the material, and this may be desirable in some applications. [0003] However, when perforated leather or similar materials are stitched, some problems arise. The presence of perforations tends to distort the established line of stitching. This happens because the needle of the sewing machine tends to preferentially enter the existing perforations in the material rather than pierce the material. Therefore, unless the direction and spacing of the st...
