Abstract
Abstract Apparatus for producing a superposed collated assemblage of sheet material on a conveyor, wherein the individual sheets are transported from sources of supply along angled paths intersecting the conveyor, and result in the deposit of the sheets on top of each other and on the conveyor in the desired collated condition as noted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A collator comprising a conveyor defining an essentially straight movement path along which plural sheets of material are adapted to be collated in superposed relation to each other, separate supplies of sheet material operatively arranged in side-by-side relation to each other and in lateral offset relation to said conveyor movement path, said conveyor and said supplies of material cooperating to bound in the angle subtended therebetween a triangular-shaped work station for performing said collation of said sheet material, and sheet-conveying means disposed at said work station operatively effective to move individual sheets fed thereon from said supplies thereof along plural angled paths intercepting said conveyor at selected locations in successively spaced relation therealong, whereby at each said intersecting location a different one of said individual sheets is deposited on said conveyor to thereby contribute to the build-up thereon of an assemblage of said sheets in a superposed collated condition.
Claim 2
Dependent Claim
149 words
A collator comprising a conveyor defining an essentially straight movement path along which plural sheets of material are adapted to be collated in superposed relation to each other, separate supplies of sheet material operatively arranged in side-by-side relation to each other and in lateral offset relation to said conveyor movement path, said conveyor and said supplies of material cooperating to bound in the angle subtended therebetween a triangular-shaped work station for performing said collation of said sheet material, and sheet-conveying means disposed at said work station operatively effective to move individual sheets fed thereon from said supplies thereof along plural angled paths intercepting said conveyor at selected locations in successively spaced relation therealong, whereby at each said intersecting location a different one of said individual sheets is deposited on said conveyor to thereby contribute to the build-up thereon of an assemblage of said sheets in a superposed collated condition.
Claim 3
Dependent Claim
33 words
A collator as defined in claim 1 wherein said conveyor is an endless pulley belt entrained at spaced apart locations about pulleys so as to define between said pulleys said straight movement path.
Claim 4
Dependent Claim
40 words
A collator as defined in claim 2 including an additional conveyor operatively disposed below the level of the discharge end of said pulley belt, to thereby facilitate the exiting removal of said collated material from said conveyor for further processing.
Claim 5
Dependent Claim
78 words
A collator as defined in claim 3 wherein said sheet-conveying means are spaced apart rollers cooperating to define plural angularly oriented material-conveying paths terminating in said intersecting relation with said conveyor, said rollers being effective to move the sheets simultaneously forwardly and progressively laterally onto said conveyor along said angled paths with optimum minimum difficulty in providing these two directions of movement because of the corresponding minimum surface contact established between the rollers and said sheets of material.
Claim 6
Dependent Claim
47 words
A collator as defined in claim 4 wherein said rollers are operatively arranged as cooperating pairs bounding said angled paths therebetween, whereby said rollers are adapted to exercise effective control over the movement of sheets of material interposed therebetween being urged in movement along said angled paths.
Claim 7
Dependent Claim
48 words
A collator as defined in claim 5 including a guide rail operatively arranged in parallel relation along the remote side of the conveyor movement path effective to limit the progressively lateral movement of the sheet material to thereby cause the deposit of said sheet material onto said conveyor.
