Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 107 words
An apparatus for feeding corrugated boards to a printing station comprising: a hopper for containing a stack of said boards; means for conveying one of said boards from said hopper to said printing station; said means for conveying having a plurality of belts including porous portions longitudinally interspersed with other portions; one guide bar intermediate each adjacent pair of said plurality of belts; and said porous portions projecting above a top surface of said guide bars and said other portions being depressed below said top surface; means for applying suction through said porous portions whereby said one of the boards is adhered to said plurality of belts.
Claim 2
Independent Claim 107 words
An apparatus for feeding corrugated boards to a printing station comprising: a hopper for containing a stack of said boards; means for conveying one of said boards from said hopper to said printing station; said means for conveying having a plurality of belts including porous portions longitudinally interspersed with other portions; one guide bar intermediate each adjacent pair of said plurality of belts; and said porous portions projecting above a top surface of said guide bars and said other portions being depressed below said top surface; means for applying suction through said porous portions whereby said one of the boards is adhered to said plurality of belts.
Claim 3
Independent Claim 128 words
An apparatus for feeding box-making corrugated boards to a subsequent printing station, the apparatus comprising: a plurality of guide bars located in a feeding direction; said guide bars extending from under a hopper to said printing station; a plurality of conveyor belts located alternately with said guide bars; each of said conveyor belts including porous parts adapted to allow a sucking pressure to pass through, wherein the top surfaces of said porous parts rise above those of said conveyor belts; said porous parts being located at intervals of a distance equal to the circumference of an impression cylinder in said printing station; and means for allowing a sucking pressure to apply to said porous parts of said conveyor belts, wherein said means is located under said conveyor belts.
Claim 4
Independent Claim 128 words
An apparatus for feeding box-making corrugated boards to a subsequent printing station, the apparatus comprising: a plurality of guide bars located in a feeding direction; said guide bars extending from under a hopper to said printing station; a plurality of conveyor belts located alternately with said guide bars; each of said conveyor belts including porous parts adapted to allow a sucking pressure to pass through, wherein the top surfaces of said porous parts rise above those of said conveyor belts; said porous parts being located at intervals of a distance equal to the circumference of an impression cylinder in said printing station; and means for allowing a sucking pressure to apply to said porous parts of said conveyor belts, wherein said means is located under said conveyor belts.
Claim 5
Dependent Claim 29 words
An apparatus as defined in claim 2, further comprising a means for adjusting said front wall of said hopper with respect to the size of boards to be processed.
