Abstract

A method of continuously deforming a sheet or strip of thermoplastics, to give an undulating or corrugated sheet, consists of passing the seet between two opposite, moving rows of blocks possessing rows of combs or projections which mesh together and thus deform the sheet into an undulating pattern between them; the envelope around any projection overlaps that around an adjacent projection, the projections being non-linear, in partic. zigzag or sine-wave shaped. The basic principle is that the sheet is continuously advanced and deformed without being laterally clamped, the front along which the oposite sets of projections engage the sheet being a non-straight line. Used for mfg. all kinds of undulating or corrugated thermoplastics sheet which might otherwise be made, e.g., by vacuum for ming.
