Abstract
A smooth press implements the application of a covering paper against a corrugated paper passing around a ribbed cylinder or roll of a single corrugator. The smooth press comprises a series of identical support arrangements arranged side-by-side along the ribbed cylinder or roll. Each arrangement has a pad whose support surface is urged against the ribbed cylinder and is curved according to a radius approximately equal to that of the ribbed cylinder in order to cover a plurality of ribs. Each pad is movable between a position disengaged from the corrugated paper and a second position biasing the cover sheet onto the corrugated paper on said ribbed cylinder and is movable individually in a controlled fashion.
