Abstract:
Knife arrangement for a granulator for granulating plastic ropes cooperating with two draw-in rollers and a cutting rotor (9) comprises a counter-knife (2), and a stripper (3) facing one of the draw-in rollers (11), whereby the counter-knife (2) and the stripper (3) are mounted on a common support (1), whereby the stripper (3) is arranged adjustably for adjustment of the distance between the stripper (3) and the draw-in roller (11), and whereby the stripper (3) has a support surface (6) for feeding the plastic ropers (12) to the counter-knife (2) and the cutting rotor (9), and is provided on one side with a stripper edge (18) projecting towards the draw-in roller (11), and on its other side with an end edge (7) projecting towards the counter-knife (2), characterized in that the support (1) has a support surface (4) facing the stripper (3), on which the stripper (3) rests with a counter surface (5) adapted to the support surface (4), whereby the support surface (6) and the counter surface (5) approach each other towards the counter-knife (2) in a converging wedge-shaped manner such that the end edge (7) is formed as a narrow edge, and the stripper (3) together with the support (1) reaches the counter-knife (2) essentially continuously with a minimal gap between the stripper (3) and the counter-knife (2), the counter-knife (2) fitting in a groove, said gap being adjacent to said groove.
