Abstract (en)

[origin: EP0649931A1] Before and/or during the execution of a spinning programme, the laundry drum is operated in a mass-determining segment M within three phases A. The first phase is characterised by a delayed increase in speed to a final speed n1 above the starting speed and below the resonant speed. The second phase B has a constant desired speed equal to the final speed n1 of the ramp. In the third phase C, the laundry drum runs down drivelessly to a minimum speed n2 which is still higher than the laundry breakaway speed. From the moment t1 when the drive is switched off to the moment t2 when the minimum speed is reached, the time span TC, which is a measure for the mass of the laundry, is measured. This detection of the loading can be carried out in an extremely simple way, is considerably more accurate than conventional methods and can be repeated at any time. A measurement of residual moisture for the purpose of checking the spinning result is likewise possible. <IMAGE>
