View Patent ↗A transfer device for adhering a transferable material to a target substrate is disclosed. The transfer device includes a supply of transfer substrate. The transfer substrate has a carrying surface and an adhesive-type transferable material provided on the carrying surface. A pressure applicator member has an engaging surface with a release characteristic and is positioned in pressure applying relation adjacent the carrying surface of the transfer substrate. The target substrate may be passed between the transfer substrate and the pressure applicator member so that the adhesive is transferred to the target substrate. The transfer device also includes a take-up roll for winding up spent portions of the transfer substrate from which the transferable material has been transferred to the target substrate.
1. A transfer device for adhering a transferable material to a target substrate, the device comprising:
a supply of transfer substrate, the transfer substrate having a carrying surface and an adhesive-type transferable material provided on the carrying surface;
a pressure applicator member positioned in pressure applying relation adjacent the carrying surface of the transfer substrate so as to enable the target substrate to be advanced in a feeding direction between the pressure applicator member and the transfer substrate for transferring at least a portion of the transferable material from the transfer substrate to the target substrate;
the pressure applicator member having an engaging surface that engages the carrying surface of the transfer substrate and the transferable material thereon, the engaging surface having a release characteristic for essentially preventing the transferable material from adhering thereto so that, as the transferable material is being transferred to the target substrate, any excess transferable material adjacent the target substrate will remain on the transfer substrate;
a take-up roll for winding up spent portions of the transfer substrate from which the transferable material has been transferred to the target substrate; and
a biasing structure biasing the supply and the pressure applicator member towards one another such that the carrying surface of the transfer substrate and the engaging surface of the pressure applicator member are pressed into engagement with one another to create the pressure applying relationship,
the biasing structure continuing to bias the supply and the pressure applicator member towards one another as the transfer substrate is depleted from the supply to thereby maintain the pressure applying relationship.
2. A transfer device according to claim 1 , wherein the pressure applicator member is a rotatable nip roller.
3. A transfer device according to claim 1 , further comprising an actuator operatively connected to at least the take-up roll to affect rotation of the take-up roll for winding up of the spent transfer substrate.
4. A transfer device according to claim 1 , wherein the supply of transfer substrate is wound in a roll.
5. A transfer device according to claim 1 , further comprising a peel plate disposed between the supply of transfer substrate and the take-up roll, the peel plate providing an edge over which the transfer substrate is bent for facilitating delamination of the target substrate from the transfer substrate.
6. A device according to claim 5 , wherein the peel plate is disposed downstream from the pressure applicator member in the feeding direction.
7. A device according to claim 5 , wherein at least a portion of the peel plate is disposed in pressure applying relation to the pressure applicator member such that the transfer substrate and the target substrate pass in between the pressure applicator and the peel plate.
8. A device according to claim 5 , wherein the peel plate and the take-up roll are positioned so that the transfer substrate is bent over the edge of the peel plate at an angle between 90° and 180° relative to the feeding direction.
