Abstract

A heat transfer sheet assembly and method is disclosed for improving the process of removing the carrier layer from a facestock layer. The heat transfer sheet assembly may include a heat transfer facestock layer and a carrier layer. The facestock layer may be attached to the carrier layer and include an indicia receptive surface along a side opposite the carrier layer. The carrier layer may include at least one peel line that extends from opposite edges of the assembly wherein the peel line assist to remove the carrier layer from the heat transfer facestock layer once indicia is printed on the facestock layer.

First claim

We claim:

1. A heat transfer sheet assembly comprising:
a heat transfer facestock layer including a first side to receive indicia thereon;
a carrier layer attached to the heat transfer facestock layer opposite from the first side; and
at least one peel line positioned along the carrier layer wherein the peel line allows a portion of the carrier layer to be removed from the heat transfer facestock layer after receiving indicia from a printer wherein said at least one peel line is formed in the carrier layer as the heat transfer facestock layer is attached to the carrier layer.

2. The heat transfer sheet assembly according to claim 1 , wherein the heat transfer facestock layer and the carrier layer share a plurality of edges and include a plurality of peel lines, the plurality of peel lines being generally parallel relative to each other and having a generally wavy shape relative to the plurality of edges along a feed direction of the sheet assembly.

3. A heat transfer sheet assembly comprising:
a heat transfer facestock layer for receiving indicia thereon, the facestock layer includes a first edge with an opposite second edge, and a third edge with an opposite fourth edge such that the edges intersect to form a generally rectangular sheet assembly wherein the third and fourth edges define a feed direction such that the heat transfer sheet assembly is configured to be fed into a printer from the first edge or the second edge,
a carrier layer is attached to the heat transfer facestock layer without an adhesive layer between the carrier layer and the heat transfer facestock layer; and
at least one peel line positioned along the carrier layer to allow at least one portion of the carrier layer to be removed from the heat transfer facestock layer after receiving indicia thereon.

4. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line extends from the first edge to the second edge.

5. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line extends from the third edge to the fourth edge.

6. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line is a generally straight cut line.

7. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line has an elongated wave form.

8. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line has a short wave form.

9. The heat transfer sheet assembly according to claim 3 , wherein the at least one peel line includes a plurality of peel lines that are generally parallel relative to one another along the feed direction of the sheet assembly.

10. A method of manufacturing a heat transfer sheet assembly comprising:
providing a heat transfer sheet assembly having a heat transfer facestock layer and a carrier layer;
cutting at least one peel line into the carrier layer such that the heat transfer sheet assembly may be fed into a printer to print indicia thereon;
wherein the peel line assists to remove portions of the carrier layer from the heat transfer facestock layer after it receives indicia thereon.

11. The method of claim 10 , further comprising cutting the at least one peel line into the carrier layer along a feed direction of the heat transfer sheet assembly.

12. The method of claim 10 , further comprising cutting the at least one peel line into the carrier layer along an axis perpendicular to a feed direction of the heat transfer sheet assembly.

13. A method of applying a heat transfer sheet assembly to an article, comprising:
generating an indicia;
providing a heat transfer sheet assembly having a heat transfer facestock layer and a carrier layer at a printer;
printing by the printer the indicia onto an indicia-receiving surface of the heat transfer facestock layer;
separating carrier portions along at least one peel line of the carrier layer to remove the carrier layer from the heat transfer facestock layer;
placing the heat transfer facestock layer on an article with the indicia-receiving surface facing outwardly therefrom; and
applying heat to the heat transfer facestock layer placed on the article to intermesh the heat transfer facestock layer and indicia to the article.

14. The method of claim 13 , further comprising cutting along a perimeter of a shape of the indicia after the indicia has been printed on the heat transfer facestock layer.

15. The method of claim 13 , further comprising placing an overlay support over the heat transfer facestock layer having the indicia thereon and providing heat through the overlay support to intermesh the facestock layer with indicia to the article.

16. The method of claim 12 , further comprising providing an overlay support over the heat transfer facestock layer after separating carrier portions along at least one peel line of the carrier layer.

17. The method of claim 12 , further comprising separating carrier portions along a feed direction of the heat transfer sheet assembly.

18. The method of claim 12 , further comprising separating carrier portions along at least one peel line of the carrier layer having at least one peel line with an elongated wave form.

19. The method of claim 12 , further comprising separating carrier portions along at least one peel line of the carrier layer having at least one peel line with a short wave form.

20. The heat transfer sheet assembly according to claim 1 , wherein said at least one peel line is formed as a generally wavy shape relative to the plurality of edges.
