Abstract
A printing press is provided having an improved register cam incorporated therein, the printing press also including a transverse alignment mechanism for aligning the printing medium prior to printing thereon. The improved register cam includes adjustment means associated therewith for selectively adjusting the linear position of the alignment member responsible for engaging and the aligning the printing medium.
Claims10
An improved register cam for use on a printing press having alignment means for transversely aligning the printing medium, said register cam comprising:
- a body;
- a camming member extending outwardly from said body;
- mounting means for operatively mounting said register cam on said printing press;
- and
- adjustment means for selectively moving at least a portion of said alignment means relative to said camming member, whereby the transverse position of said alignment means is adjustable in response to the operation of said adjustment means.
An improved register cam for use on a printing press having alignment means for transversely aligning the printing medium, wherein said alignment means includes a driving portion and a driven portion, said register cam comprising:
- a body, having transverse adjustment means incorporated therein;
- a cam member extending outwardly from said body, said cam member having a bearing surface for operatively engaging said driving portion of said alignment means, said driving portion being alternatingly positionable between first and second positions;
- and
- mounting means, for pivotably mounting said register cam on said printing press, said register cam being pivotable between first and second positions corresponding to said first and second positions of said driving portion of said alignment means;
- wherein
- said adjustment means are operatively securable to said driven portion of said alignment means, such that the pivoting of said register cam between said first and second positions thereof operates to move said driven portion between corresponding first and second positions;
- said adjustment means being operative to provide for selective transverse placement of said driven portion of said alignment means in said first and second positions thereof.
An improved printing press, comprising:
- a platen;
- alignment means for transversely aligning the printing medium on said platen prior to printing, said alignment means including a driving portion and a driven portion, said driven portion including an alignment member for engaging a portion of said printing medium and moving said printing medium to a pre-selected location on said platen;
- and
- a register cam having adjustment means incorporated therein, said register cam comprising:
- mounting means for pivotably mounting said register cam near said platen;
- a bearing surface for slidingly engaging a portion of said driving portion of said alignment means;
- and
- attachment means for operatively securing a portion of said driven portion of said alignment means;
- wherein
- said register cam provides for mechanical communication between said driving and driven portions of said alignment means, whereby alternating rotational movement of said driving portion is converted into alternating linear movement of said driven portion, said adjustment means being operative to provide for selective linear positioning of said alignment member.
An improved printing press, comprising:
- a platen;
- alignment means for transversely aligning the printing medium on said platen prior to printing, said alignment means including an alignment member for engaging a portion of said printing medium and moving said printing medium to a pre-selected position on said platen;
- a register cam associated with said alignment means;
- and
- adjustment means, associated with said register cam, for selectively adjusting the transverse position of said alignment member relative to said platen.
