Abstract: The invention relates to a method for driving one or several pile carriers (2) for the selection of one or several pile yarns (15), the pile carriers (2) moving between a first and a second extreme position for pile selection, each pile carrier (2) being directly driven through a drive motor (4), and activating the drive motor (4) for driving the pile carrier (2) occurring either according to the half reset principle, the pile carrier (2), each time being moved over an intermediate position, this intermediate position being a position between two extreme positions for pile selection, and the position of the pile carrier (2) being verified in this intermediate position, or occurring without half reset, one half reset movement being carried out in verification of the fact whether all pile carriers (2) are still in the positions verified, after a number of movements of the pile carrier (2) or after a certain time, said half reset movement being a movement of one or several pile carriers towards an intermediate p

Abstract: A method and a device for controlling a winder, where the winding torque (Tw), during winding, is controlled as a function of the desired tractive force in the material to be wound. During winding, repeatedly is calculated which value a quantity (Vl), influencing the winding torque (Tw), has to adopt in order to obtain a desired tractive force (Fw), and an adjustment of the said quantity (V1) is carried out, the calculated value being used as an objective value. Preferably, the calculation is done by an algorithm, expressing the said quantity as a function of the desired tractive force (Fw), as a function of one or more fixed parameters which are characteristic for winding up material or for the winder, and as a function of one or more variable parameters, being measured or calculated during winding. The device also relates to a winder comprising a winding body (1), (2) for winding a material, a drive device (3,9),(4,10) for driving this winding body (1), (2) an a control device.

Abstract: The invention relates to a device for driving one or several pile carriers (2) for the selection of one or several pile yarns (15), comprising at least one drive motor (4) for driving a pile carrier (2), the pile carrier moving under the motor housing (7) of the drive motor and the motor shaft (5) of the drive motor (4) being provided with driving means (6) for directly driving the pile carrier (2), the pile carrier (2) being provided for performing a linear back and forth movement.
