CA 2299551

A polymer cutter with a rotary cutting head in which the cutting edges are on the circumferential periphery of the head, and in which the cutting edges shear rather than slice the polymer is described. The knife blades on the rotary head have a cutting edge angle of greater than 70°. The apparatus is especially useful for cutting thermoplastics and may be used for preparing polymer granules or pellets.

L'invention concerne un outil de coupe de polymère doté d'une tête coupante rotative dans laquelle les bords tranchants se trouvent à la périphérie circonférentielle de la tête, et dans laquelle les bords tranchants cisaillent le polymère au lieu de le découper en tranches. Les lames de couteau se trouvant sur la tête rotative présentent un angle de bord tranchant supérieur à 70 DEG . L'appareil est particulièrement utile pour couper des thermoplastiques et peut être utilisé pour préparer des granules ou des particules de polymère.
