Abstract

A printed product transfer assembly for supporting and carrying printed product from one station in a printer apparatus to another station includes a transfer structure including a product conveying surface, a blanket including fiberglass having several outwardly protruding fiberglass fibers and being secured snugly over the conveying surface; a flexible resilient material secured snugly over the blanket and engaged against circumferential movement relative to the blanket by the fiberglass fibers, and having several ridges for engaging and conveying the printed products and for cushioning the printed products to prevent marring of printing ink. The printed product transfer assembly preferably still further includes a delivery shaft; a transfer cylinder including releasibly interconnected first and second longitudinal cylinder half portions, each half portion including an arched outer shell segment forming a portion of a printed product conveying surface and first and second shell segment half hub structures secured respectively within and to the first and second longitudinal cylinder half portions, the half hub structures including delivery shaft receiving structure and hub inter-connection elements releasibly joining the first and second half hub structures together; and a transfer cylinder anti-rotation collar for fixing the transfer cylinder against rotation about and relative to the delivery shaft.

Independent Claims | See all claims (10)

1. 1. A printed product transfer assembly for supporting and carrying printed products from one station in a printer apparatus to another said station, comprising:a transfer structure comprising a product conveying surface,a blanket comprising fiberglass having a plurality of outwardly protruding fiberglass fibers and being secured snugly over said conveying surface;a flexible resilient material secured snugly over said blanket and engaged against circumferential movement relative to said blanket by said fiberglass fibers, and having a plurality of ridges for engaging and conveying said products and for cushioning said products to prevent marring of printing ink.
2. 7. A method of preparing a printing press transfer structure having a product conveying surface for transferring printed products from one station of a printer apparatus to another station, comprising the steps of:covering at least part of said conveying surface with a flexible blanket comprising fiberglass fibers;covering at least part of said blanket with yielding ridged material;tightening said ridged material over said conveying surface to a tension level sufficient to take up slack in said material but insufficient to Pull out said ridges; andwire brushing said blanket to cause fiberglass fibers to protrude, to more securely hold said ridged material against motion relative to said blanket.
3. 8. A printed product transfer assembly for supporting and carrying printed products from one station in a printer apparatus to another said station, comprising:a transfer structure comprising a product conveying surface, a blanket comprising fiberglass having a plurality of outwardly protruding fiberglass fibers and being secured snugly over said conveying surface;a flexible resilient material secured snugly over said blanket and engaged against circumferential movement relative to said blanket by said fiberglass fibers, and having inward and outward material faces and a plurality of wrinkles with crests in said outward material face producing corresponding troughs in said inward material face, wherein said crests define collapsible ridges for engaging and conveying said products and for cushioning said products to prevent marring of printing ink.
4. 9. A printed product transfer assembly for supporting and carrying printed products from one station in a printer apparatus having a delivery shaft to another said station, comprising:a transfer cylinder comprising releasibly interconnected first and second longitudinal cylinder half portions, each said half portion comprising an arched outer shell segment forming a portion of a product conveying surface and first and second shell segment half hub structures secured respectively within and to said first and second longitudinal cylinder half portions, said half hub structures comprising delivery shaft receiving means, said first half hub structure delivery shaft receiving means comprising hub interconnection means releasibly connecting said first and second half hub.sup.2 structures together;and transfer cylinder anti-rotation collar means, for fixing said transfer cylinder against rotation about and relative to said delivery shaft, said anti-rotation collar means comprising first half hub structure releasible engaging means for releasibly connecting said first half hub structure to said delivery shaft while said second half hub structure is secured to said first half hub structure.
