PURPOSE: A corrugation forming roller for manufacturing corrugated papers is provided to facilitate manufacture because each air collection groove has a head area and an air connection channel is extended from the head area. CONSTITUTION: A corrugation forming roller for manufacturing corrugated papers comprises a rotary axial line, a corrugation forming unit(5), and an air discharge unit. The corrugation forming unit comprises corrugation forming top parts, corrugation forming gully parts and corrugation forming side parts The corrugation forming side parts connect the corrugation forming top parts and the corrugation forming gully parts each other. The air discharge unit comprises one or more air collection grooves(19), one or more air connecting channels(23), and one or more air suction channels(25). The air collection grooves are outwardly opened to a radius direction. The air collection grooves are partially formed around the rotary axial line. The air collection grooves cross with part of the corrugation forming top parts and are composed of a first side wall(20) and a second side wall(21) facing each other. The air connection channels are extended from at least one of the side walls of the air collection groove. The air suction channels are connected with the flow of at least one air connection channel to receive negative pressure. |
