Abstract

A method and apparatus for generating hot stamped single and multi-colored images wherein a transferable image is generated at a first station and a substrate or container is decorated at a second station. The transferable image is generated via a hot stamping mechanism (a single or multi-head station) onto a transfer film at the first station, and the transfer image is then transferred via hot stamping onto the part or substrate at the second station via a hot stamping transfer technique referred to as foilprint.

Claims

1. A two-stage apparatus for generating an image on a substrate to be decorated, said apparatus comprising:

a) a first stage at which a transfer image is generated on a transfer film, said transfer film comprising a web;

b) means for advancing said transfer film in an advancing direction through said first stage;

c) means for generating said transfer image on one side of said transfer film at said first stage;

d) a second stage at which said transfer image formed on the one side of said transfer film is transferred and bonded to the substrate;

e) means for moving said transfer film having said transfer image formed thereon to said second stage, the substrate being located at said second stage;

f) means, at said second stage, for applying heat and pressure to said transfer film on a side opposite to said one side having said transfer image formed thereon, such that said transfer image is brought into contact with the substrate and is transferred and bonded to the substrate; and

g) a C-shaped frame for supporting said first and second stages, wherein said means for moving moves said transfer film from said first stage to said second stage without advancing said transfer film in the advancing direction.

2. The two-stage apparatus according to claim 15, wherein said first and second stages are disposed side-by-side in said C-shaped frame and are aligned along a first plane, and wherein said means for advancing said transfer film through said first stage is disposed perpendicular to said first plane.

3. The two-stage apparatus according to claim 2, wherein said means for moving said transfer film to said second stage comprises a carriage means, said carriage means movably supporting said means for advancing said transfer film, such that said means for advancing said transfer film is movable between said first and second stages.

4. The two-stage apparatus according to claim 3, wherein said means for advancing said transfer film comprises a transfer film unwind for storing said transfer film, a plurality of nip rollers and a transfer film rewind for taking-up said transfer film after said transfer image has been transferred and bonded to the substrate at said second stage.

5. A two-stage apparatus for generating an image on a substrate to be decorated, said apparatus comprising:

a) a first stage at which a transfer image is generated on a transfer film, said transfer film comprising a web;

b) means for advancing said transfer film through said first stage;

c) means for generating said transfer image on one side of said transfer film at said first stage;

d) a second stage at which said transfer image formed on the one side of said transfer film is transferred and bonded to the substrate;

e) means for moving said transfer film having said transfer image formed thereon to said second stage, the substrate being located at said second stage;

f) means, at said second stage, for applying heat and pressure to said transfer film on a side opposite to said one side having said transfer image formed thereon, such that said transfer image is brought into contact with the substrate and is transferred and bonded to the substrate; and

g) a frame for supporting said first and second stages, wherein said first and second stages are disposed side-by-side with respect to said frame and are aligned along a first plane, and wherein said means for advancing said transfer film through said first stage is disposed perpendicular to said first plane.

6. The two-stage apparatus according to claim 5, wherein said means for moving said transfer film to said second stage comprises a carriage means, said carriage means movably supporting said means for advancing said transfer film, such that said means for advancing said transfer film is movable between said first and second stages.

7. The two-stage apparatus according to claim 6, wherein said means for advancing said transfer film comprises a transfer film unwind for storing said transfer film, a plurality of nip rollers and a transfer film rewind for taking-up said transfer film after said transfer image has been transferred and bonded to the substrate at said second stage.
