The invention relates to a corrugating roll (2) for a single-facer for corrugated board of the kind comprising a pair of corrugating rolls (1,2) providing meshing fluted surfaces for corrugating a web (3) fed therethrough and in which one face of the corrugated web is attached to a liner web.
<??>An object of the invention is to provide a single-facer of this kind which, compared with known arrangements, is simple to manufacture and easy to maintain.
<??>The invention is characterized in that said corrugating roll is in the form of a roll cell fluted on its outer peripheral surface, a plurality of grooves are provided at appropriate spaced intervals along the outer peripheral surface of said roll cell so as to encircle said roll cell in the circumferential direction at right angles to said flutes, a plurality of bores (24) are provided in said roll cell which extend almost over its entire length, which bores respectively open into one common end surface of said roll cell and partly communicate with the bottoms of said grooves, and suction means disposed at said common one end surface of said roll cell for applying suction via said bores and grooves. |
