Abstract
Abstract Apparatus for mounting a matrix on a plate cylinder in a dyetransfer apparatus, wherein the plate cylinder is provided with a cut away portion, and a cover member has a shape that is complementary with the shape of the cut away portion. A register pin is provided on the surface of the cut away portion for engaging one end of a matrix mounted thereon, and a fixture is provided for fixing the other end of the matrix to the surface of the cut away portion. A cylindrical member, mounted within the plate cylinder or the cover, is urged toward the surface of the cut away portion by spring means to tension the matrix when the cover member is fixed to the cut away portion of the plate cylinder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
An arrangement for mounting a matrix on a hollow plate cylinder in a dye-transfer apparatus, said arrangement comprising: a plate cylinder having a surface plane formed by an axially cut away portion, a cover member having a shape mating with the cut away portion of the plate cylinder, at least one register pin provided on the surface plane of the cut away portion for engaging one end of a matrix mounted thereon, a fixture for fixing the other end of the matrix to the surface of the cut away portion, and a member urged toward the surface plane of said plate by spring means, said fixture being on one lateral side of the member urged and on the same side of said member urged as said at least one register pin so that the member urged can be used for tensioning the matrix by contact therewith when the cover member is fixed to the cut away portion of the plate cylinder.
Claim 2
Dependent Claim
161 words
An arrangement for mounting a matrix on a hollow plate cylinder in a dye-transfer apparatus, said arrangement comprising: a plate cylinder having a surface plane formed by an axially cut away portion, a cover member having a shape mating with the cut away portion of the plate cylinder, at least one register pin provided on the surface plane of the cut away portion for engaging one end of a matrix mounted thereon, a fixture for fixing the other end of the matrix to the surface of the cut away portion, and a member urged toward the surface plane of said plate by spring means, said fixture being on one lateral side of the member urged and on the same side of said member urged as said at least one register pin so that the member urged can be used for tensioning the matrix by contact therewith when the cover member is fixed to the cut away portion of the plate cylinder.
Claim 3
Dependent Claim
22 words
An arrangement for mounting a matrix on a plate cylinder as defined in claim 1 wherein said spring-urged member is a roller.
Claim 4
Dependent Claim
24 words
An arrangement for mounting a matrix on a plate cylinder as defined in claim 2 wherein said roller is provided within the plate cylinder.
Claim 5
Dependent Claim
25 words
