Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
A multiple station screen stencil printing press apparatus for stencil printing repeat images of multiple colors on generally continuous web stock, comprising: a plurality of webreceiving operative stencil screen printing stations spaced by web slack receiving zones, arranged to enable a continuous web to pass consecutively therethrough; web advancing means at each of said printing stations; at least two spaced registry tab applicator means upstream of said stations on opposite sides of the center line of the web travel path for applying at least two spaced tabs to the web on opposite sides of the centerline of the web; and at least two tab engaging registry means at said stations, positioned to engage consecutive tabs on the web for web registry at the successive stations, thereby enabling a multiple of colors to be printed on the web in accurate registry through the successive stations.
Claim 2
Dependent Claim
