Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A sheet material processing apparatus comprising: a. a guide member in the form of a chute having a surface curved in the plane perpendicular to the direction in which the sheet material is fed; and b. means for feeding said sheet material in the curved condition resulting from contact with said guide member, and longitudinally extending slots carried by said guide member for accommodating said sheet material feeding means.
Claim 2
Dependent Claim
69 words
A sheet material processing apparatus comprising: a. a guide member in the form of a chute having a surface curved in the plane perpendicular to the direction in which the sheet material is fed; and b. means for feeding said sheet material in the curved condition resulting from contact with said guide member, and longitudinally extending slots carried by said guide member for accommodating said sheet material feeding means.
Claim 3
Dependent Claim
63 words
The apparatus as claimed in claim 1, further comprising an auxiliary guide member in the form of a second chute, concentrically carried within said first chute and defining a narrow arcuate slot therebetween for passage of sheets therethrough, means intermediate said member and said auxiliary guide member guide and adjacent said curved sheet material for subjecting said sheet material to a specific treatment.
Claim 4
Dependent Claim
57 words
The apparatus as claimed in claim 2, wherein said sheet material feeding means comprises a first pair of spaced apart wheels protruding through said slots and into the path of said sheet material and a second pair of spaced apart wheels disposed adjacent to said first pair of wheels for engaging and feeding said sheet material therebetween.
Claim 5
Dependent Claim
56 words
The apparatus as claimed in claim 2, wherein said sheet feeding means comprises a first pair of spaced apart wheels protruding through said slots and into the path of said sheet material, and a second pair of spaced apart wheels disposed adjacent to said first pair of wheels for engaging and feeding said sheet material therebetween.
Claim 6
Dependent Claim
53 words
The apparatus as claimed in claim 4, further comprising longitudinal slots carried by said second chute and overlying the slots carried by said first chute with said first pair of wheels protruding through the slots of said first chute, and said second pair of wheels protruding through the slots of said second chute.
Claim 7
Dependent Claim
90 words
A sheet material processing apparatus comprising: a. a guide member in the form of a chute having a surface curved in the plane perpendicular to The direction in which the sheet material is fed; b. means for feeding said sheet material in the curved condition resulting from contact with said guide member; c. said guide member being waved shaped in the plane perpendicular to the direction in which the sheet is fed; and d. further means adjacent the outer edges of said waved shaped surface for feeding said sheet material.
Claim 8
Dependent Claim
90 words
A sheet material processing apparatus comprising: a. a guide member in the form of a chute having a surface curved in the plane perpendicular to The direction in which the sheet material is fed; b. means for feeding said sheet material in the curved condition resulting from contact with said guide member; c. said guide member being waved shaped in the plane perpendicular to the direction in which the sheet is fed; and d. further means adjacent the outer edges of said waved shaped surface for feeding said sheet material.
Claim 9
Dependent Claim
22 words
The apparatus as claim in claim 6 wherein said guide member is integrally grooved to limit lateral movement of said sheet material.
Claim 10
Dependent Claim
49 words
The sheet material processing apparatus as claimed in claim 1, wherein said sheet material feeding means comprises first roller means protruding through said slots and into the path of said sheet material and second roller means disposed above said first roller for engaging and feeding said sheet material therebetween.
