Abstract
A loading device (10) is used to adjust the size of a blade gap (9) in processing equipment for processing fibrous material. The loading device has a gearing (12) coupled in connection with a processing element (5, 6) to move the processing element (5, 6) in respect of another processing element (5, 6) for adjusting the size of the blade gap (9) between the processing elements. A cage induction motor (14) has a shaft (15) coupled to the gearing for operating the gearing, a position sensor (16) for measuring a rotational position (M-RP) of the shaft of the motor for indicating a position of the processing element in respect of the another processing element, and a frequency converter (17) coupled to the position sensor and to the motor for controlling the operation of the motor based on the measured rotational position of the shaft of the motor.
