Abstract
The invention relates to a device for granulating plastic strands having a cutting wheel (15), the individual blades of which graze past a counter blade (2) disposed in a blade carrier (1) when the cutting wheel is rotated, thus cutting the plastic strands (13) being guided over the counter blade into a granulate (14), wherein a rail (3a, 3b) composed of hard material running parallel to the counter blade is disposed adjacent to the counter blade and after said counter blade in the rotational direction of the cutting wheel that collects cut granulate and conducts said granulate into a discharge channel. The rail is held in a guide having an undercut (8, 9) in the blade carrier on both sides, wherein the undercut (9) facing the counter blade forms a separating strip (10), the thickness of which reduces outward in a blade-like fashion such that, along with the other undercut (8), the rail assumes an oblique position relative to the counter blade in the transverse direction, wherein the outer edge (11) of the undercut (9) facing the counter blade is in close proximity to the opposite front edge (12) of the counter blade and the other front edge of the rail protrudes in the direction of the cutting wheel.
