Abstract

Apparatus for the longitudinal corrugation of thermoplastic sheet material in the plastic state has two series of movable shaping belts which progressively overlap each other, the belts moving with the sheet and following a straight path in the cooling zone for the shaped sheet, and being supported and guided by the plates of an endless chain acting on their face which is not in contact with the sheet. Gives corrugated plastic sheet for use as a constructional material. High quality corrugated sheet is produced continuously and economically. The corrugations may be curved or polygonal. The shaping belts are pref. made from a material with a thermal conductivity below 10-3 cal/cm. sec. degree C., a hardness above 45 shore A units, an elastic elongation >0.3% and abrasion wear 300 mm3 (DIN 53516), esp. of rubbers, polyamides, polyolefins polyaldehydes, or polycarbonates.
