A heald loom comprises a weaving machine (1) and a dobby (2) which can be coupled to one another via a mechanical transmission apparatus (3) and have a common drive train in the coupled state which can be driven by a main drive (5) It further comprises an auxiliary drive (6) which is arranged to act at least on the part of the drive train driving the dobby. The heald loom further comprises at least one sensor (7, 8) which measures the torque actually present at the drive train and which is arranged along the drive train in the region between the weaving machine (1) and the dobby (2) or in the end region of the weaving machine (1) or the dobby (2) respectively bordering on this region. This sensor (7, 8) is connected to a control system (9) which actuates the auxiliary drive (6) in such a manner that the torque and/or fluctuations in the speed of rotation present between the weaving machine (1) and the dobby (2) are reduced.
Heald loom system comprising a weaving machine and a dobby coupled to one another by a mechanical transmission apparatus driven by a main drive to effect a common drive train in the coupled state which is subjected to torque and/or fluctuations in a speed of rotation present between the weaving machine and the dobby, the loom system further comprising an auxiliary drive which is arranged to act at least on a part of the drive train driving the dobby, and at least one sensor which measures the torque encountered at the drive train and arranged along the drive train in a region between the weaving machine and the dobby or in an end region of the weaving machine or the dobby respectively, bordering on the region;
A method for controlling a torque and/or fluctuations in a speed of rotation between a weaving machine and a dobby of a heald loom, the weaving machine and the dobby being coupled to each other by a mechanical transmission apparatus driven by a main drive to effect a common drive train in their coupled state, the heald loom including an auxiliary drive acting at least on a part of the drive train driving the dobby, the method comprising the steps of monitoring the torque encountered at the drive train;
