ABSTRACT:
In the case of a mounting for an opening roller comprising a plurality of teeth, all the tooth faces and the tooth backs are inclined in rotational direction. At their tips, the tooth faces form an angle relative to an opening roller radial plane of between 10.degree. and 30.degree. . The tooth backs are more inclined to the radial plane at the tooth tips than at the tooth bases. The tooth backs are inclined at the tooth tips in such a way that an extension of the tangent to the tooth back at the tooth tip intersects the tooth face of the following tooth at an intersecting point which is between one-fifth and four-fifths of the tooth height of the following tooth. At least one-half of a tooth height from the tooth tip to the tooth base has a roller circumferential direction width which is at least as large as the distance between the back of the respective tooth and the face of a next adjacent following tooth.
