Corrugator

The present invention relates to a corrugator, which includes a machine table; a first rolling mechanism disposed on one side of the machine table, at least having a plurality of correspondingly-arranged straight line generating roller sets; and a second rolling mechanism disposed on another side of the machine table, at least having a corrugating roller, a transverse line generating roller and a prickle-surfaced roller respectively meshed with the two sides of one end of the corrugating roller, a glue spraying unit installed between the corrugating roller and the transverse line generating roller, and a planar roller and a glue coating unit correspondingly disposed on the two sides of another end of the corrugating roller. Accordingly, the first and second rolling mechanisms are used to perform required pattern embossing and combining on at least three working materials, so as to achieve the objectives of increasing structural strength after combination of working materials, while increasing pressure resista
