Abstract
A blade (6) for underwater granulation of an extruded polymer, this blade has a plate (60) bounded by a contour including a cutting edge contour (61) having a first end (62) and a second end (63), and an outer contour (64) linking the first end (62) and the second end (63) of the cutting edge contour (61). The outer contour (64) has at least a first bearing portion (65) and a second bearing portion (66), the first bearing portion (65) and the second bearing portion (66) diverging while extending away from the cutting edge contour (61) and configured to be received in a dovetail housing (13).
Claims15
A blade for underwater granulation of an extruded polymer, the blade comprising a plate that extends in a longitudinal direction, bounded longitudinally by a contour including:
- a cutting edge contour having a first end and a second end, the cutting edge contour extending in the longitudinal direction, and
- an outer contour linking the first end and the second end of the cutting edge contour,
- wherein the contour, including the cutting edge contour and the outer contour, is of a trapezoidal shape and the outer contour comprises at least a first bearing portion and a second bearing portion, the first bearing portion and the second bearing portion diverging while extending away from the cutting edge contour and being configured to be received in a dovetail housing.
A blade for underwater granulation of an extruded polymer comprising a plate comprising:
- a length extending in a longitudinal direction of the plate that is longer than a width extending in a transverse direction with respect to the longitudinal direction of the plate;
- a first side defining a top surface and an opposite second side defining a bottom surface;
- a first bevel extending in the longitudinal direction and extending from the second surface to the first surface at an oblique angle with respect to the second surface, the first bevel defining a cutting edge in the longitudinal direction, the cutting edge having a first end and a second end;
- and
- a second bevel extending in the longitudinal direction and in the transvers direction so as to define a contour around three sides of the plate and link the first end and the second end of the cutting edge, the second bevel extending from the first surface to the second surface at an oblique angle with respect to the first surface;
- wherein the contour defines a first bearing portion and a second bearing portion, the first bearing portion and the second bearing portion diverging while extending along the transverse direction and configured to be received in a dovetail housing.
