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 position between two extreme positions for pile selection before moving to a next position for color selection.
