Abstract
Paper drive apparatus for multi-ply unglued paper wherein a centrally disposed pin wheel member is rotatable in contact with a backup member the latter having a central groove or slot into which the pins of the pin wheel member are rotatably receivable. Unglued, multi-ply paper is fed into the nip between the pin wheel member and the bifurcated backup roller across a demountable, flexible paper guide, the latter ensuring the proper angle of entry of the unglued paper with respect to the nip between the pin wheel and backup roller.
Claims4
In printing apparatus having printing means including fixed data thereon and impact imparting means for printing on paper stock interposed between said impact imparting means and said printing means and wherein paper stock is fed from a supply to said printing means by a web drive means the improvement comprising;
- means mounting multi-ply unperforated unglued paper stock adjacent to said printing means for feed to said printing means;
- means for simultaneously engaging each of the plies of said paper stock so as to feed said stock with each ply in register with the other plies of said stock to said printing means, said means for simultaneously engaging each of said plies comprises a demountable, rotatable, resilient member provided with a circularly disposed ring of paper stock pentrating elements and having a drive engaging member axially aligned therewith for demountable engagement with operably associated web drive means of the printing apparatus
- means conjointly operable with said means for engaging each of the plies and having a longitudinal axial extent greater than said ply engaging means providing intimate longitudinal contact with said paper stock and acting to maintain said stock in a substantially flat condition adjacent to said printing means;
- and
- means for adjusting the entering angle of said paper stock relative to said printing means enabling said ply engaging means to entrap said plies prior to said printing means substantially horizontally eliminating any drag coefficient on the paper
- said means for simultaneously engaging and said means for adjusting being snap-in demountable with respect to said printing apparatus.
