Par la demande de brevet allemand publiée sous le N O 40 22 715, on connaît un procédé d'essorage de ce type dans lequel la phase de fonctionnement consécutive du cycle d'essorage se déroule avec une The German patent application published under No. 40 22 715 discloses a spinning method of this type in which the consecutive operating phase of the spinning cycle takes place with a

vitesses de rotation réglées jusque là, est déclenché. rotational speeds set so far, is triggered.
Un procédé d'essorage connu de ce type présente l'inconvé- A known spinning method of this type has the disadvantage
nient de suivre une courbe fixe préétablie pour le cycle d'essorage principal Toutes les charges de linge sont traitées de la même manière deny following a fixed curve preset for the main spin cycle All laundry loads are treated in the same way

ges de linge mal adaptées à cette courbe préétablie, un résultat d'es- laundry that is ill-suited to this preset curve, a result of
sorage ou une durée de traitement qui laisse à désirer Par ailleurs, les dispositifs amortisseurs montés dans un lave-linge doivent être conçus pour le rapport le plus défavorable entre courbe d'essorage principale fixe et charge de linge correspondante, d'o des dépenses importantes qui pourraient être évitées. L'objet de la présente invention est d'améliorer un procédé d'essorage décrit en introduction de telle sorte que l'on puisse adapter le profil des phases d'essorage individuellement aux charges de linge à traiter de manière à permettre d'une part de ménager le linge et d'autre part d'obtenir un meilleur essorage et de réduire les dépenses pour des sorage or a treatment duration which leaves something to be desired Furthermore, the damping devices mounted in a washing machine must be designed for the most unfavorable ratio between the fixed main spin curve and the corresponding laundry load, resulting in significant expenditure that could be avoided. The object of the present invention is to improve a spinning process described in the introduction so that the profile of the spinning phases can be adapted individually to the loads of laundry to be treated so as to allow on the one hand to save the laundry and on the other hand to get a better spin and reduce expenses for
dispositifs amortisseurs dans les lave-linge. damping devices in washing machines.
Le problème est résolu selon l'invention par le fait que l'on fait varier également la raideur de la rampe de montée en vitesse et la durée d'essorage au cours de la ou des phases de fonctionnement du The problem is solved according to the invention by the fact that the stiffness of the speed-up ramp and the spin time are also varied during the operating phase or phases of the

Des interdépendances analogues existent également lorsqu'on atteint la vitesse de rotation finale du cycle d'essorage principal l est par conséquent judicieux de régler la vitesse de rotation finale en fonction de la quantité et/ou de la nature de la charge du tambour ainsi que de la valeur du balourd Un balourd relativement élevé pondéré Similar interdependencies also exist when the final rotation speed of the main spin cycle is reached. It is therefore advisable to adjust the final rotation speed as a function of the quantity and / or the nature of the load of the drum as well as of the unbalance value A relatively high weighted unbalance
