Method for applying and fastening a décor layer

A method for applying and fastening a decorative layer on a preform for the formation of a support part, wherein the preform comprises:

• a first section which is to be laminated with the decorative layer;
• a second section;
• and
• a connecting section connecting the first section and the second section along a groove extending in a longitudinal direction and in a groove depth direction, wherein the connecting section comprises a first region adjoined to the first section of the preform and a second region adjoined to the second section of the preform, and
• wherein the method comprises the steps of:
• connecting the first section of the preform to the decorative layer by closing a first tool,
• wherein an end section of the first tool bends and disposes an end section of the decorative layer against at least a portion of the first region of the connecting section,
• moving the first and a second tool, onto which the second section of the preform is placed, relative to one another in the groove depth direction, whereby the second region of the connecting section is deformed and the end section of the decorative layer is introduced in the groove depth direction into the groove, and
• moving the first and the second tool relative to each other across the groove depth direction and thereby pressing together side walls of the groove to fix the end section of the decorative layer in the groove.
