  • the working surface 10 is formed in one piece by the associated working projection 9, which in turn is formed in one piece with the associated supporting body 11, as a result of which the one-piece working member 3 to 5 is formed.
  • the working member 6 serving as the only balancing weight has no projection and is also formed in one piece.
  • the outermost circumference of the base body 2 forms a cylindrical support surface 17, which extends over the entire length of the working links 3 to 6.

  • the shanks 33 or the heads 32 of all securing members 28 can be of the same design in terms of length, external width and / or thread pitch, so that only the same screws 28 are required, all of which can be exchanged for one another. Accordingly, all pins 29 are of the same design.
  • the arc distance of the holes 18 associated with the working member 3 or 4 corresponds to the average arc distance of the associated openings 22, so that when the surface 31 of a securing member 28 is immediately adjacent to the associated edge 14 or 15, the surface 31 of the other edge 15 or 14 adjacent securing member takes the greatest distance from this edge or approximately adjoins the inner end of the associated opening 22, but the working member cannot be removed from the base body.
  • a sliding guide 35 is formed between two opposing, concentrically curved or parallel sliding surfaces 17, 31 for each of the two working members 3, 4, which prevent radial play movements of the working member 3, 4 transversely to the sliding surfaces , but allow adjustment movements only in and against the direction of travel 34 of the tool 1 by manually moving the working member 3, 4 relative to the base body 2 without an actuator. Small game movements are also possible in the longitudinal direction. Both or all adjustable working members 3, 4 can be adjusted independently of one another and independently of all other working members 5, 6.
  • the tool 1 or its working surfaces 10 serve to cooperate with the circumference of a counter-tool, which can be rotated about an axis parallel to the tool 1 and forms a width-adjustable gap for the material.
  • the width can be adjusted in particular by radial adjustment of the counter tool.
  • the material is clamped between the work surface 10 and the possibly circumferentially resilient counter circumference and at the same time the groove is embossed with the work surface 10 such that it represents a non-reversible machining or deformation.
  • the counter circumference is continuously cylindrical and smooth, so that the working projection 9 can engage in any circumferential area with the same effect and no counter grooves are required for the engagement of the working surfaces 10.
  • the counter tool and the tool 1 are so drive-connected to one another, for example via a single-stage belt drive, that each work surface 10 meets a different circumferential point of the counter tool in each subsequent revolution than in the preceding revolution in order to protect it.
  • the counter circumference can be formed by an elastomer coating of the continuously smooth cylindrical and dimensionally stable, rigid circumference of a roll core made of steel or the like and have a hardness of approximately 40-80 Shore.
  • the consistently constant thickness of the coating is advantageously about 10 mm.
  • the design and arrangement of the counter tool can also be provided independently of all other designs.
  • the working member 3a can also have two or more immediately adjacent and mutually parallel working projections 9 between the rows of openings 22.
  • the end of the respective projection 9 is expediently set back slightly with respect to the associated end edge 16.
  • the working members 3, 4 can be adjusted so far in both directions that one of their running edges 14, 15 strikes the opposite running edge 15, 14 of the adjacent working member 5, 6 and then there is no gap between these running edges, while the Gap on the leading edge removed from it is enlarged accordingly.
