ABSTRACT:
A single-face corrugating machine comprising two cooperating serrated rollers and a pressure roller cooperating with one of said serrated rollers. The tooth root contour of at least one serrated roller is designed as a concave curve; the corrugating impression from the machine takes place mainly when the central lines of the tooth tips and tooth roots coincide with the connection line of the roller axes. The toothing of the serrated rollers and the shape of the pressure roller is such that the respectively cooperating zones of tooth tip and tooth root are designed with a constant axial spacing of the respectively cooperating serrated rollers. At least two teeth are simultaneously in impression engagement over the entire length of engagement with constant axial spacing of one serrated roller with the pressure roller. The pressure roller comprises axially parallel longitudinal grooves whose contours are rolling curves of the tooth tip of the second serrated roller cooperating with said pressure roller.
