Abstract: A machine is on a first side of a plate (20) and a rod (50) passes along or through the plate (20). The plate (20) is susceptible to vibrations arising from operation of the machine. An active vibration suppressor (60) is mounted on the rod (50), and a controller is configured to control the active vibration suppressor (60) to suppress vibrations of the plate (20).

Abstract: A process and a device for operating a synchronous winding machine, includes an assembly of shafts for driving packages, shafts for driving fliers and a device for pre-feeding yarns. The process comprises controlling with an electronic device a driving in synchronism of the pre-feeding device and the drive shafts of packages, as well as drive shafts for the fliers of packages, with adjustment or variation of the angle of crossing of the yarns by wobulation or electronic scrambling/jamming or by any other signal of variation of the angle of crossing. The invention is most particularly applicable to the field of the textile industry, in particular winding machines for yarns and particularly synchronous winding machines.
Abstract: An open-end rotor spinning machine having a plurality of work stations, wherein each work station comprises an open-end spinning device for manufacturing a yarn, a winding device with a creel, a yarn traversing device for producing a cheese, a pivotably supported, vacuum-chargeable suction nozzle, an individual drive for pivoting the suction nozzle between a yarn take-up position in the area of the winding device and a yarn transfer position in the area of a spinning piecing member, and a device for preparing a yarn end required for restarting spinning. Each work station comprises a winding device with a drive drum driven by a reversible individual drive for driving a cheese and with a yarn traversing device driven by an individual motor for defined placement of the yarn running up onto the cheese, a yarn withdrawal device, and a work-station computer for controlling the individual drives and individual motors.
