Abstract

Abstract A machine for mounting a printing plate on a plate roll having an adhesively coated face. The machine includes a frame, means for rotatably mounting a plate roll on the frame in a selected position, a tilting framework swingably mounted on the frame and a pair of table sections mounted on the tilting framework on which the printing plate can be slideably mounted. A transparent grid plate is hingedly mounted on the tilting framework and can overlie the printing plate on the table sections. The printing plate can be advanced across the table section until the grid shows that the printing plate is properly aligned with the plate roll. Then a movable one of the table sections can be withdrawn and the printing plate can be advanced downwardly to bring a portion of the printing plate into engagement with the plate roll for attaching the printing plate to the plate roll. The plate roll can be turned to bring the rest of the printing plate into engagement with the adhesively coated face of the plate roll.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 152 words
A machine for mounting a printing plate on a plate roll having an adhesive coated face which comprises a frame, means on the frame for rotatably mounting the plate roll in a selected position, a tilting framework swingably mounted on the frame, a pair of table sections mounted on the tilting framework and overlying the plate roll for supporting the printing plate, means on the tilting framework for aligning the printing plate with the plate roll while the printing plate is supported on the table sections, there being a space between the table sections, the tilting framework swinging to a position at which the adhesive coated face of the plate roll engages the printing plate through the space, and means for turning the plate roll to cause the printing plate to engage flatwise the adhesive coated face for causing adhesion of the printing plate to the adhesive coated face in proper registry.
Claim 2
Dependent Claim 152 words
A machine for mounting a printing plate on a plate roll having an adhesive coated face which comprises a frame, means on the frame for rotatably mounting the plate roll in a selected position, a tilting framework swingably mounted on the frame, a pair of table sections mounted on the tilting framework and overlying the plate roll for supporting the printing plate, means on the tilting framework for aligning the printing plate with the plate roll while the printing plate is supported on the table sections, there being a space between the table sections, the tilting framework swinging to a position at which the adhesive coated face of the plate roll engages the printing plate through the space, and means for turning the plate roll to cause the printing plate to engage flatwise the adhesive coated face for causing adhesion of the printing plate to the adhesive coated face in proper registry.
Claim 3
Dependent Claim 35 words
A machine as in claim 1 in which one of the table sections is slideably mounted on the tilting framework for removal from the path of the printing plate as the plate roll is turned.
Claim 4
Dependent Claim 56 words
A machine as in claim 1 in which the means on the tilting framework for aligning the printing plate with the plate roll includes grid sheet means for overlying the printing plate on the table sections so that the printing plate can be adjusted to aligned position while held in position below the grid sheet means.
Claim 5
Dependent Claim 79 words
A machine as in claim 1 in which the means for mounting the plate roll in a selected position includes a rotatable shaft, index disc means mounted to turn with the shaft, latch means for engaging the index disc means to hold the index disc means in selected position, a clutch disc mounted on the shaft for turning therewith, and clutch means on the plate roll engageable by the clutch disc to hold the plate roll in selected position.
