Claim 6

Apparatus as in claim 4 wherein each of said pairs of feeder elements comprises a pair of arcuately shaped elements which conform to said cylindrical support on their inward surfaces and are adapted to bear against such sheet material on their outward surfaces and which attach to each said pair of adjacent slots in overlapping telescopic relation for spanning a variety of spaCings from the length of one of said elements to the combined lengths of said pair of elements.

Claim 7

Apparatus as in claim 4 wherein said pair of slots extend circumferentially about the perimeter of said support at each end.

Claim 8

Apparatus as in claim 1 wherein said scoring portions comprises an elongated frame means captively retaining a plurality of acerose perforators in substantially in-line relationship to one another, said frame means supporting said perforators, such that the points thereof extend beyond said frame means for engaging and scoring such sheet material.

Claim 9

Apparatus as in claim 1 wherein said scoring portions secured to one of said bars includes a blade element and inwardly angled supplemental blades for forming a truncated V-shape score in such sheet material.

Claim 10

Apparatus as in claim 1 wherein said cylindrical support means includes a plurality of disc members each comprising a pair of semicircular parts adapted to be fastened to one another.

Claim 11

Apparatus as in claim 1 wherein said scoring portions on an adjacent pair of said elongated mounting bars are fastened to adjacent sides of the respective mounting bars such that a pair of said scoring means may be positioned at a variety of closely spaced adjacent positions by adjusting said mounting bars on said support means.

Claim 12

In an envelope making machine including a horizontal guide bed over which paper envelope stock is moved during processing and an envelope feeding and scoring system having juxtaposed elements above and below said bed and transverse thereto wherein one of said elements is the feeding and scoring apparatus and the other of said elements presents a resilient pressure surface defining therebetween a locus or paper line at the pitch diameter of the feeding system through which the paper stock passes, the improvement comprising: said feeding and storing apparatus including a cylindrical support drivingly mounted for rotation about an axis transverse to said guide bed, paper stock feeding members attached to said support and having arcuately shaped bodies conforming to said support and further having protruding surfaces radially extending to said pitch diameter for capturing paper stock against said resilient pressure surface, a plurality of paper stock scoring elements attached to said support and each including a mounting portion and a scoring portion, said mounting portion being an elongated bar extending generally parallel to said axis and attached to said support, said bar being of substantial width circumferentially of said support, feeding means extending across the width of said bar and extending radially to said pitch diameter for capturing paper stock against said resilient pressure surface, said scoring portion being an elongated narrow member mounted on said mounting portion and including an outwardly disposed edge for scoring such stock, said edge protruding radially beyond said pitch diameter defined by said feeding members, said support formed with axially spaced mounting ways extending annularly about the circumference thereof, threaded fasteners including first components captured within said ways, and cooperating threaded components adjustably attaching said mounting portions and said feeding members to said first components whereby said scoring elements and feeding members may be readily adjusted about the circumferential periphery of said support by loosening said fasteners and sliding said fasteners along said ways such that a pair of said scoring portions may be positioned at a variety of circumferentially spaced adjacent positions by adjusting said scoring elements on said support, and said feeding means and members forming a continuous paper stock feeding engagement with said resilient means from one scoring edge to the next scoring edge such that paper stock is continuously engaged at said pitch diameter during scoring between said juxtaposed elements.

Claim 13

In an envelope making machine including a horizontal guide bed over which paper envelope stock is moved during processing and an envelope feeding and scoring system having juxtaposed elements above and below said bed and transverse thereto wherein one of said elements is the feeding and scoring apparatus and the other of said elements presents a resilient pressure surface defining therebetween a locus or paper line at the pitch diameter of the feeding system through which the paper stock passes, the improvement comprising: said feeding and storing apparatus including a cylindrical support drivingly mounted for rotation about an axis transverse to said guide bed, paper stock feeding members attached to said support and having arcuately shaped bodies conforming to said support and further having protruding surfaces radially extending to said pitch diameter for capturing paper stock against said resilient pressure surface, a plurality of paper stock scoring elements attached to said support and each including a mounting portion and a scoring portion, said mounting portion being an elongated bar extending generally parallel to said axis and attached to said support, said bar being of substantial width circumferentially of said support, feeding means extending across the width of said bar and extending radially to said pitch diameter for capturing paper stock against said resilient pressure surface, said scoring portion being an elongated narrow member mounted on said mounting portion and including an outwardly disposed edge for scoring such stock, said edge protruding radially beyond said pitch diameter defined by said feeding members, said support formed with axially spaced mounting ways extending annularly about the circumference thereof, threaded fasteners including first components captured within said ways, and cooperating threaded components adjustably attaching said mounting portions and said feeding members to said first components whereby said scoring elements and feeding members may be readily adjusted about the circumferential periphery of said support by loosening said fasteners and sliding said fasteners along said ways such that a pair of said scoring portions may be positioned at a variety of circumferentially spaced adjacent positions by adjusting said scoring elements on said support, and said feeding means and members forming a continuous paper stock feeding engagement with said resilient means from one scoring edge to the next scoring edge such that paper stock is continuously engaged at said pitch diameter during scoring between said juxtaposed elements.
