Abstract
The present disclosure concerns a module (100) for inline embossing of a leather product (1) comprising a leather support sheet (2) having a surface finish layer of one or more partially cured coating layers. The module comprises an application means (10) to apply a protective foil (4) onto the partially cured layer (3) to form a laminate (5). The module also comprises a pressure group (20) including an embossing roller (21) having an outer surface with a relief structure (22) so as to emboss a negative of the surface relief structure into the leather product, across the protective foil.
Claims15
A module (100) configured for embossing of a leather product (1) comprising a leather support sheet (2) having a surface finish layer of one or more partially cured coating layers (3), said module comprising at least:
- an application means (10) configured to, in use, apply a protective foil (4) onto the partially cured layer (3) to form a laminate (5) by feeding the protective foil and leather product between a first pair of rollers, said first pair of rollers including an ironing roller (11) and a first counter roller (12), and
- a pressure group (20) configured to, in use, apply an embossing pressure to the laminate between a second pair of rollers, said second pair of rollers including an embossing roller (21) having an outer surface with a relief structure (22) and a second counter roller (23), so as to emboss a negative of the surface relief structure into the leather product, across the protective foil;
- wherein the module is configured to, in use, convey the leather product from the application means past the pressure group by means of an elongate sheet of the foil conveyed along a conveying trajectory (33) from a foil supply (31) provided upstream of the laminating means to a foil retriever (32) provided downstream of the pressure group and
- characterized in that the second counter roller (23) is provided with a felt layer (24) arranged around said second counter roller to accommodate thickness variation of the leather support sheet.
