摘要

Method and device for aligning the blades of a tool head of a granulating device for thermoplastics. BR/ We very gradually bring the head (4) tool holder and a lapping plate (3) covered with a layer (9) of abrasive material together, and align the blades (6) in a same plane of rotation by running in. In the device, the head (4) tool holder, stationary and driven in rotation, is mounted, with the bell (2) which surrounds it, on a receiving plate (1) and the lapping plate (3) is fixed to the free end of the bell (2). BR/ Application in particular to the maintenance of devices for manufacturing granules of thermoplastic materials.
