Abstract
Abstract A continuous printer including a framework supporting an endless platen and means to move material onto the platen for movement therewith. Printing means comprising an endless stencil screen mounted on spaced rolls are disposed adjacent to one run of the platen for printing the material and includes ink distributing means. The ink distributing means includes a housing removably supported on the framework and defining a substantially enclosed ink cavity disposed about an applicator roller journalled in the housing. A table supports the run of the platen opposite the printing means and a friction reducing band of a material of a lower surface friction coefficient than that of the material of the platen is disposed between the rungs of the platen and has a run which extends between the platen and the table and is movable with the platen for reducing friction between the platen and the table. Toothed means are provided for movement with the platen and mesh with toothed means on the screen supporting rollers to drive the rollers and to insure continued registration between the stencil screen and the material to be printed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
In an apparatus for continuously printing on a moving flexible material comprising a platen for receiving said material to be printed, said platen comprising a movable endless web having a top run and a bottom run, means for moving said material over said platen for movement therewith, printing means adjacent one of said runs of said platen for continuously printing said material supported by said platen, and a table supporting that portion of said one of said runs disposed opposite said printing means, the improvement comprising a movable endless friction reducing band of substantially planar sheet-like material having a surface friction coefficient less than that of said Platen disposed within said endless platen and having a run extending between said platen run and said table and movable with said platen, thereby reducing friction between said platen and said table.
Claim 2
Dependent Claim
139 words
In an apparatus for continuously printing on a moving flexible material comprising a platen for receiving said material to be printed, said platen comprising a movable endless web having a top run and a bottom run, means for moving said material over said platen for movement therewith, printing means adjacent one of said runs of said platen for continuously printing said material supported by said platen, and a table supporting that portion of said one of said runs disposed opposite said printing means, the improvement comprising a movable endless friction reducing band of substantially planar sheet-like material having a surface friction coefficient less than that of said Platen disposed within said endless platen and having a run extending between said platen run and said table and movable with said platen, thereby reducing friction between said platen and said table.
Claim 3
Dependent Claim
63 words
The apparatus of claim 1 and including a second endless platen vertically spaced from said first platen with said printing means being disposed therebetween, and a second supporting table and a second friction reducing band for said second platen disposed in relation to said second platen as said first supporting table and first friction reducing band are disposed relative to said first platen.
Claim 4
Dependent Claim
230 words
In an apparatus for continuously printing on moving flexible material having lateral edge portions, comprising a platen for receiving said material to be printed having a lateral width less than that of said material, said platen comprising a movable endless web having lateral side portions and having a top run and a bottom run, means for moving said material into contact with and over said one of said runs of said platen, with said edge portions overlying said side portions of said one of said runs, printing means mounted adjacent said one of said platen runs for continuously printing said material as it passes between said one of said runs of said platen and said printing means, said printing means including a pair of drums, an endless screen mounted for movement over said pair of drums, a table supporting that portion of said one of said runs adjacent said printing means, resilient strip means mounted adjacent the side portions of said one run of said platen and movable therewith for engaging and holding said edge portions against said side portions of said one of said runs, the improvement comprising gear means peripherally disposed about at least one end of each of said drums, and teeth means on said resilient strip means for driving interengagement with said gear means, whereby accurate registration between the printing means and said material is maintained.
Claim 5
Dependent Claim
230 words
In an apparatus for continuously printing on moving flexible material having lateral edge portions, comprising a platen for receiving said material to be printed having a lateral width less than that of said material, said platen comprising a movable endless web having lateral side portions and having a top run and a bottom run, means for moving said material into contact with and over said one of said runs of said platen, with said edge portions overlying said side portions of said one of said runs, printing means mounted adjacent said one of said platen runs for continuously printing said material as it passes between said one of said runs of said platen and said printing means, said printing means including a pair of drums, an endless screen mounted for movement over said pair of drums, a table supporting that portion of said one of said runs adjacent said printing means, resilient strip means mounted adjacent the side portions of said one run of said platen and movable therewith for engaging and holding said edge portions against said side portions of said one of said runs, the improvement comprising gear means peripherally disposed about at least one end of each of said drums, and teeth means on said resilient strip means for driving interengagement with said gear means, whereby accurate registration between the printing means and said material is maintained.
Claim 6
Dependent Claim
302 words
In an apparatus for continuously printing on moving flexible material having lateral edge portions, comprising a platen for receiving said material to be printed having a lateral width less than that of said material, said platen comprising a movable endless web having lateral side portions and having a top run and a bottom run, means for moving said material into contact with and over said one of said runs of said platen, with said edge portions overlying said side portions of said one of said runs, printing means mounted adjacent said one of said platen runs for continuously printing said material as it passes between said one of said runs of said platen and said printing means, a table supporting that portion of said one of said runs, resilient strip means mounted adjacent the side portions of said one run of said platen and movable therewith for engaging and holding said edge portions against said side portions of said one of said runs, bearing means secured to said table on each side of said one run of said platen for forcing said strip means toward said side portions to grip said edge portions of said material, said bearing means comprising rollers mounted on verticle axes, framework adjacent said strip means for supporting said rollers, the improvement comprising an endless friction reducing band mounted around said rollers and extending substantially the length of said one run of said platen, said band having one face in contact with said strip means for movement therewith, and a second movable endless friction reducing band having a surface friction coefficient less than that of said platen disposed within said endless platen and having a run extending between said platen run and said table and movable with said platen thereby reducing friction between said platen and said table.
Claim 7
Dependent Claim
