<p>FIELD: printing arts. SUBSTANCE: cell drum rotating about the central axis carries cells separated from one another by spokes. Knives are secured on the spokes in such a manner that each cell on two opposite ends of the cell drum is respectively confined by a knife. Each end face of the cell drum carries at least one fixed counter-knife, which is engaged with the rotating knives. In the plane normal to the central axis the cell drum is divided into two halves of the cell drum, which are respectively installed on a supporting body. Both supporting bodies can move relative to each other along the central axis. The counter-knives participate in movement, since they rest on one of the supporting bodies. EFFECT: simplified procedure of adjustment of cell drum to items of different formats. 10 cl, 13 dwgn</p> |
