Abstract
PURPOSE: To make possible the continuous manufacture of wide and long corrugated sheet for use of lining the tank, etc., through one pass, by cutting the tip of the blank into an angle, and by feeding it into the multiple-corrugation former.
CONSTITUTION: The blank S is uncoiled, and its tip is cut to form an angle whose lateral middle is projecting forward. The top width H of this angle is specified to be a little larger than the pitch of corrugations formed in the corrugated sheet. This blank S is fed into the multiple-corrugation former 5 from the tip part 14. The multiple corrugations are formed in the blank S by the forming roll groups 17A, 17B, arranged at constant pitch in the feeding direction into the multiple stages. The setting pitch for unit rolls 17a, 17b, between respective forming roll groups 17A, 17B, is made gradually smaller toward the latter stage, and the wave height of the formed corrugation is made gradually higher toward the latter stage. According to this shape of the tip of the blank S, the lateral slip against the forming roll becomes minimum, and besides, te corrugated sheet with accurately pitched corrugations are easily manufactured.
