Disclosed is a weaving machine, including: In addition, disclosed is an associated method for detecting abnormal variations in pile-forming in a weaving machine.

Weaving machine with device and method for detecting variations in pile-forming

Disclosed is a weaving method with which the yarn tension of several part groups with at least one warp thread per part group is controlled or adjusted separately, in order to follow a respective reference yarn tension profile during weaving, where, for at least one part group, the reference yarn tension profile is changed during weaving, where the reference yarn tension profile is determined and changed separately for at least two part groups, and where each reference yarn tension profile is selected from a collection of different reference yarn tension profiles. Also disclosed is a weaving machine provided with yarn tensioning elements, a storage unit in which said collection is provided, and a control or steering unit in order, in cooperation with the yarn tensioning elements, to adjust or control the yarn tension in separate warp threads using the indicated weaving method.

Disclosed is a yarn tensioning system for keeping at least one yarn, which is taken from a yarn storage system to a yarn take-off system of a weaving machine, under tension. The system includes a brake roller around which the yarn is at least partially wound, and a motor for supplying a torque to the brake roller, the motor being actuable in generator operation to keep the yarn under tension between the brake roller and the yarn take-off system. Also disclosed is a weaving machine including such a yarn tensioning system, as well as a method for keeping at least one yarn under tension, the at least one yarn being taken from a yarn storage system to a yarn take-off system.

A method and a device for controlling a winder, where the winding torque (T ), 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 (V ), influencing the winding torque (T ), has to adopt in order to obtain a desired tractive force (F ), and an adjustment of the said quantity (V ) 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 (F ), 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 ( ), ( ) for winding a material, a drive device ( ),( ) for driving this winding body ( ), ( ) an a control device.
