Abstract
A labeling machine for heat-shrink labels, comprising, arranged progressively along the path of the bottles: a first adhesive bonding device, which applies to the surface of a bottle a film of adhesive at a strip of limited dimensions; a transfer drum, which conveys a label from a second adhesive bonding device, which arranges a film of adhesive that polymerizes as a consequence of exposure to UV rays on the trailing edge of the label, until contact occurs with a bottle so that the leading edge of the label is located at the film of adhesive; and at least one UV-ray emission lamp.
Claims3
A labeling machine for heat-shrink labels, comprising a rotating carousel provided with means for supporting bottles to be labeled with circumferential labels, said means being adapted to turn the bottles about their axis so as to produce adhesion, on a surface of said bottles, of the labels with an overlap region at leading and trailing edges of the label, comprising, arranged progressively along a path of the bottles:
- a first adhesive bonding device, adapted to apply to the surface of the bottle a film of adhesive at a strip of limited dimensions;
- a transfer drum, adapted to convey a label from a second adhesive bonding device, adapted to arrange a film of adhesive of the type that polymerizes as a consequence of exposure to UV rays on a strip located at the trailing edge of the label, until contact occurs with a bottle so that the leading edge of said label is located at the film of adhesive applied previously;
- at least one UV-ray emission lamp, located at the path traced by a bottle with the label permanently applied thereto and facing the overlap region of the leading and trailing edges of said label, which is provided with the film of adhesive arranged by the second adhesive bonding device.
