Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
202 words
A hot stamping die construction for decorating under heat and pressure an irregular surface of a plastic part to be decorated, said construction comprising a relatively thin, flexible first metal plate having substantial shear strength and having a stamping surface adapted to bear against said irregular surface of said part, said plate being of such flexibility as to enable it to be deformed temporarily to conform to the irregular surface of said part; a second metal plate spaced from said first metal plate; a layer of resilient, heat-conductive, synthetic rubbery material of substantial thickness relative to that of the first metal Plate and sandwiched between and secured to said first and second plates; means for mounting said second plate on a platen adapted to be moved toward and away from said part and operable to press said first plate against said part under sufficient pressure to conform said first plate to said surface of said part; and means for applying sufficient heat to said first plate through said second plate and said rubbery material while said first plate bears against and conforms to the surface of said part to enable heating and decorating of said surface of said part by deforming same.

Claim 3
Dependent Claim
13 words
The construction set forth in claim 1 wherein said first plate is steel.
Claim 4
Dependent Claim
13 words
The construction set forth in claim 1 wherein said first plate is copper.
Claim 5
Dependent Claim
13 words
The construction set forth in claim 1 wherein said first plate is aluminum.
Claim 6
Dependent Claim
32 words
The construction set forth in claim 1 wherein said stamping surface of said first plate has a coating thereon of metal harder than the metal of which said first plate is formed.
Claim 7
Dependent Claim
20 words
The construction set forth in claim 1 wherein said first plate has secured to its stamping surface a copper plate.
Claim 8
Dependent Claim
20 words
The construction set forth in claim 1 wherein said first plate is heated to a temperature not exceeding 500* F.
Claim 9
Dependent Claim
14 words

Claim 10
Dependent Claim
222 words
A hot stamping die construction for decorating under heat and pressure an irregular surface of a part to be decorated, said construction comprising a relatively thin, flexible first metal plate having substantial shear strength and having a stamping surface adapted to bear against said irregular surface of said part, said plate being of such flexibility as to enable it to be deformed temporarily to conform to the irregular surface of said part; a second metal plate spaced from said first metal plate; a layer of resilient, heat-conductive, synthetic rubbery material of substantial thickness relative to that of the first metal plate and sandwiched between and secured to said first and second plates; a thin layer of film having a release coating thereon interposed between said first plate and said part to be decorated; means for mounting said second plate on a platen adapted to be moved toward and away from said part and operable to press said first plate against said part under sufficient pressure to conform said first plate to said surface of said part; and means for applying sufficient heat to said first plate through said second plate and said rubbery material while said first plate bears against and conforms to the surface of said part to enable the release coating on said film to be transferred to said part.
