Abstract

An apparatus and method is provided for forming a textured pattern on a heated substrate. An extruder forms the heated substrate. A textured pattern is applied to a transfer sheet by rotary screening. Thereafter, contact is made between the textured pattern and the substrate for adhering the textured pattern to the substrate. Since the textured pattern has a greater affinity for the substrate than for the transfer sheet, the transfer sheet can be removed from the textured pattern adhered to the substrate. In a preferred application, the textured pattern formed on the substrate can be used as a vertical, horizontal or venetian blind.

Claims

1. A method for forming a textured pattern on a blind comprising the steps of:

applying said textured pattern to a releasable transfer sheet by rotary screening, said transfer sheet being substantially flat, said textured pattern having a thickness between 5 and 10 mm;

presenting a heated blind to said textured pattern;

contacting said heated blind with said textured pattern for causing said textured pattern to adhere to said blind; and

releasing said transfer sheet from said textured pattern adhered to said blind,

wherein said pattern has a greater affinity for said blind than for said transfer sheet.

2. The method of claim 1 wherein said heated blind is formed by an extruder.

3. The method of claim 2 wherein said blind is heated to a temperature of at least 270°

F.

4. The method of claim 3 wherein said blind is formed of a material chosen from the group of thermoplastic, polyvinyl chloride and polyethylene.

5. The method of claim 4 wherein said transfer sheet is chosen from the group comprising silicone release paper, quilan, release paper and polyester.

6. The method of claim 5 said blind has a width of between about 0.5 and 5.0 inches.

7. The method of claim 6 wherein said textured pattern is formed of thermosetting material.

8. The method of claim 6 wherein said textured pattern is formed of rubber.

9. The method of claim 6 wherein said textured pattern is formed of an expandable material.

10. The method of claim 6 wherein said textured pattern is formed of plastic.
