Machine for producing a cup

A machine for producing a cup made of composite material, namely from an outer shell and an inner cup, comprising:

• a plurality of first holding devices, which are arranged on a first rotatably mounted star- or wheel-like holding device carrier,
• a plurality of second holding devices, which are arranged on a second rotatably mounted star- or wheel-like holding device carrier,
• at least one first workstation arranged in the region of the first holding devices for performing at least one of the steps:
• providing a winding for forming the outer shell, winding the winding onto or into one of the first holding devices, compressing and/or adhering ends of the winding wound onto or into one of the first holding devices, with the ends forming a seam area of the outer shell,
• a transfer station for transferring a finished outer shell from one of the first holding devices of the first holding device carrier to one of the second holding devices of the second holding device carrier,
• at least one second workstation arranged in the region of the second holding devices for performing at least one of the steps:
• pushing the outer shell into one of the second holding devices or pushing the inner cup onto one of the second holding devices, pushing a finished inner cup into the finished outer shell or pushing the finished outer shell onto the finished inner cup, checking finished cups, rejecting defective cups, removing the finished cups from the second holding device, and
• a preparation station for, prior to providing the winding for forming the outer shell, prebending one of the ends of the winding for forming an adhesive tab in the seam area and performing at least one of the following steps:
• separating one of the windings for forming the outer shell from a stack, heating the seam area or the entire winding, applying an adhesive in the seam area.
