Claims

[Scope of utility model registration request]

It consists of a pair of forming rollers, each of which has a plurality of protrusions extending in the axial direction on its outer circumferential surface and is formed at regular pitches in the circumferential direction, and which are arranged in an interlocking state and at least one of which is driven. , one of the forming rollers is provided with recesses of a predetermined depth in each of the protrusions so as to form a line in the circumferential direction of the forming roller, and a protrusion is provided at a portion spaced apart from the recesses in the axial direction. Protrusions of a predetermined height are provided in each valley between the strips so as to form a line in the circumferential direction, and the other forming roller has protrusions facing each of the recesses of the one forming roller. At the required part of each valley between the striations,
Protrusions of a predetermined height that can fit into the respective recesses of the one forming roller are provided, and the protrusions of the one forming roller are provided at required portions of the protrusions facing the respective protrusions of the one forming roller. A forming device for a corrugated plate having recesses in the peaks of a corrugated surface, in which recesses of a predetermined depth are provided into which the respective protrusions can fit.
