摘要

The roller for transporting sheets or lengths of material, especially a folding drum, has a surface made of the same material as the basic part of the roller, with elastic, non-slip coatings inset into grooves in the roller base material. Easily deformable, hardening materials (7) are inserted between the grooves (2) of the basic part of the roller (1) and form a tight join with the elastic annular coatings (4). The bottom of the grooves (2) and/or coatings (4) have recesses (5, 8, 9) in them. USE/ADVANTAGE - The roller for transporting sheets of paper turns securely and improves the quality.
