ABSTRACT:
Apparatus for making corrugated sheet comprises a pair of meshed flexure compensating grooved rolls and laying-on means for applying a cover sheet to a corrugated web. Hydraulically-operated flexure compensating means are employed, advantageously pistons with hydrostatic lubrication. One of the grooved rolls cooperates with the laying-on means, which may be a pressure roll, a pneumatic hood with a suction chamber, or a traveling belt, and the grooved roll has flexure compensating means acting against the laying-on means. With a pressure roll, flexure compensating means may be employed therein which acts against the cooperating grooved roll. The axis of rotation of the roll shell of one grooved roll may be fixed, and the other grooved roll which cooperates with a pressure roll may have a roll shell disposed for radial or linear translation. The plane of the axes of the cooperating pressure and grooved rolls may be at a substantial angle to the plane through the axes of the pair of grooved rolls, preferably 90.degree.. One or more rolls may be heated by heated hydraulic fluid, or heated air may be used in the pneumatic hood, or heat applied otherwise for setting an adhesive.
