Abstract
Abstract A method and apparatus for adhering foil to a given surface. The foil is initially supported at one face of a flexible carrier which must be stripped from the foil subsequent to the adhering thereof to the surface. The foil is adhered to the surface by heat-ironing brought about through suitable rollers, and subsequent to the adhering of the foil to the surface the carrier is continuously wound onto a stake-up roll so that the carrier is progressively from the foil to carry out the stripping operations. These stripping operations are brought about in part by movement of the surface and foil with respect to a stripping roll and in part by movement of the stripping roll with respect to the surface to which the foil is adhered, so that the extent to which the surface and foil must be fed is diminished by the extent to which the stripping roll is moved with respect to the surface and the foil adhering thereto. Also the carrier and foil are derived from a supply roll supported on a swingable frame which moves the supply roll from a given starting position to a given end position during the adhering of the foil to the surface, and a return structure returns the swingable frame back to its starting position after the operations are completed, so that in this way the edge of the foil which is first displaced toward the surface is backed up from the region of the last of the series of heat-ironing rollers to the region of the first thereof, thus reducing waste of foil.

Total Claims: 12
Claim 1
Independent Claim
181 words
In a method of adhering to a given surface a foil which is initially carried by a flexible carrier at one face of the latter, the steps of heat-irOning the foil to the surface by applying heat and pressure through the carrier to the foil while the foil engages but does not move with respect to the surface, and continuously winding the carrier onto a take-up roll while progressively peeling the carrier from the foil subsequent to heat-ironing thereof to said surface, so that said carrier is progressively stripped from the foil while the latter adheres to the surface, said heat-ironing being brought about by a plurality of rollers which sequentially bring about heat-ironing of the foil to the surface and with the edge of the foil at the end of one complete cycle of operation being situated in the region of the last of the rollers which is actuated, and backing said edge of the foil to the region of the first of the rollers to be actuated prior to the next operating cycle so that foil waste is reduced.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
197 words
In a method of adhering to a given surface a foil which is initially carried by a flexible carrier at one face of the latter, the steps of heat-ironing the foil to the surface by applying heat and pressure through the carrier to the foil while the foil engages but does not move with respect to the surface, and continuously winding the carrier onto a take-up roll while progressively peeling the carrier from the foil subsequent to heat-ironing thereof to said surface, so that said carrier is progressively stripped from the foil while the latter adheres to the surface, the stripping of the carrier from the foil being carried out in two operations during one of which the surface and foil are moved together with respect to a stripping roll around which the carrier moves to the take-up roll and during the other of which the stripping roll is moved with respect to the surface and foil which remain stationary, during the continuous take-up of the carrier onto the take-up roll, whereby the stroke required for the surface and foil is diminished to the extent that the stripping roll moves with respect thereto during said other operation.
Claim 4

In a method of adhering to a given surface a foil which is initially carried by a flexible carrier at one face of the latter, the steps of heat-ironing the foil to the surface by applying heat and pressure through the carrier to the foil while the foil engages but does not move with respect to the surface, and continuously winding the carrier onto a take-up roll while progressively peeling the carrier from the foil subsequent to heat-ironing thereof to said surface, so that said carrier is progressively stripped from the foil while the latter adheres to the surface, the stripping of the carrier from the foil being carried out in two operations during one of which the surface and foil are moved together with respect to a stripping roll around which the carrier moves to the take-up roll and during the other of which the stripping roll is moved with respect to the surface and foil which remain stationary, during the continuous take-up of the carrier onto the take-up roll, whereby the stroke required for the surface and foil is diminished to the extent that the stripping roll moves with respect thereto during said other operation.
