[0004] However, the ribbing method of the known type is not without its drawbacks, which include the fact that said seam between one rib and the adjacent rib of the covering is visible and therefore unaesthetic, especially from the point of view of the end consumer to see
[0005] Another disadvantage of known types of ribbing methods is that they allow exclusively to provide coverings with ribs having a substantially circular cross-section

Embodiment Construction

[0026] Referring to the drawings, the ribbing method according to the invention, in particular for providing leather coverings, generally indicated by the reference numeral 10, essentially comprises the following steps.

[0027] Initially, in step 12 , a treated covering material 32 , such as a portion of leather or fabric, is spread over a form 34 .

[0028] Formwork 34 comprises a plate-like base 36 having a variable extension and a plurality of longitudinally extending and preferably mutually parallel crests 38 of variable height and mutual distance.

[0029] Preferably, template 34 is made of metal. Even more preferably, formwork 34 is made of aluminum or its alloys.

[0030] Formwork 34 includes a plurality of longitudinally extending, preferably parallel to each other, abutments 40 shaped and bounded by a plate-like base 36 and a plurality of longitudinally extending, preferably parallel to each other, ridges 38 .

[0031] The height of each abutment 40 corresponds sub...

Abstract

A ribbing process (10), particularly for providing leather coverings, comprising the steps of: applying (12) a covering material (32) on a template (34) that comprises a plurality of longitudinally extended seats (40), inserting (14) a plurality of longitudinally extended forming rods (42) in the plurality of seats (40) of the template (34), making the covering material (32) adhere to the template(34) and providing a plurality of seats (33) in the covering material (32), hot pressing (16) a first assembly that comprises the template (34), the covering material (32), and the plurality of forming rods (42), thermoforming the covering material (32), removing (18) from the first assembly the plurality of forming rods (42), cooling (20) the template (34) and the covering material (32).

Description

technical field [0001] The present invention relates to a method of ribbing, particularly but not exclusively useful and practical in the production of leather coverings, such as can be used in the field of furniture for the manufacture of armchairs, sofas and the like. Background technique [0002] In the terms of the trades in which the textile and furniture sectors operate, ribbing means forming a more or less raised rib obtained by suitable working effects in a material such as leather or fabric. [0003] Ribbing of leather or fabric coverings is currently done with a variety of stitches applied to the material being processed. These stitches separate one rib from the adjacent ribs and allow for the rib's typical visual and aesthetic appearance. [0004] However, the ribbing method of the known type is not without its drawbacks, which include the fact that said seam between one rib and the adjacent rib of the covering is visible and therefore unaesthetic, especially fro...
