Abstract
A coating apparatus in which a coating film is transferred from a film carrying roll leaf, onto the surface of a product. A positioning platform, together with a pressure member which acts against the platform, define a transfer station at which the roll leaf and product are concurrently aligned. A continuously moving and guided thermal belt preheats the foil sufficiently to effect separation of the roll leaf decorative layer from the carrier, and assure its transfer to the product surface.
Claims14
Apparatus for applying a decorative roll leaf to the surface of a product 11, from a foil comprising a carrier strip having said decorative roll leaf detachably adhered with a thermally meltable adhesive to one side thereof, which apparatus includes;
- a platform 16 adapted to support said product 11,
- a pressure member 24 having an outer surface positioned adjacent to said platform 16 and being operable to exert a force in the direction of the latter, and to define a transfer station 13 therebetween,
- product handling means positioned adjacent to said transfer station whereby to guide said product into said station,
- foil transfer means 37, 39 positioned to introduce said foil into said transfer station 13 and into registry with said product 11 surface,
- a thermal belt 41 defining a closed loop,
- a heat source 44,
- belt guide means engaging said thermal belt 41 to progress the latter along said closed loop, and to guide a belt section sequentially into heat exchange relationship with said heat source 44, and thence into heat exchange contact with at least a part of the outer surface of said pressure member, whereby to melt said adhesive and to cause separation of said decorative roll leaf from said carrier strip and transfer thereof to the product surface at said transfer station 13.
