Abstract
The corrugated boards contained in a hopper are individually kicked out onto conveyor belts on which each board firmly sticks thereto under suction from below, and are fed to a subsequent processing station, such as a printing station, thereby enabling the individual boards be fed in their right posture to a right place in the processing station.
Claims3
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.

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.
