A method for calibrating a thread storage unit that can be arranged at a workstation of a textile machine. The method comprises the calibration steps of: setting of a calibration torque of the electric motor in the control system, wherein the calibration torque is lower than the maximum torque acting on the thread guide arm due to the magnetic repelling effect of the coupling elements; activation of the electric motor of the drive unit for adjusting the thread guide arm with the calibration torque to a rest position against a stop of the thread guide unit by the control system; and storage of the set position of the thread guide arm and the electric motor as the zero position of the thread guide arm and the electric motor in the control system.

A fiber delivery system capable of providing cut fiber segments for use in treating an oil and/or gas well. The fiber delivery system can utilize bales of a continuous filamentary tow that are transported to the well site from a remote manufacturing location. At the well site, a multifilament strand can be pulled off the bale, opened, and cut to provide cut fiber segments. The cut fiber segments can be mixed with other well treatment components to create a well treatment medium that is introduced into the well as part of a drilling, stimulation, or cementing process.

The invention relates to a method for operating a textile machine which serves to produce roving (1), wherein during roving production a roving (1) having a protective twist is produced by means of at least one consolidating means from a fiber bundle (3) that is fed to the consolidating means, wherein the roving (1) produced by the consolidating means is wound by a winding device (5) onto a tube (7), wherein the roving (1) during the winding process is guided by means of a guide element (23) which is arranged between the consolidating means and the tube (7), and wherein the guide element (23) exerts a decelerating effect on the roving (1). According to the invention, it is proposed that the decelerating effect is adapted during operation of the textile machine in such a way that it is lower during a start procedure, while the roving (1) leaving the consolidating means is being brought into contact with a tube (7), preferably an empty tube (7), and/or during a tube change, while a wound tube (7) is being replaced by an empty tube (7), than during a winding process that takes place between the start procedure and the tube change. A textile machine for producing a roving (1) is also described, said textile machine having at least one controller which is designed to operate the textile machine in accordance with the method according to the invention.

Method for implementing a correct winding of a wire on a spool (100). The method also comprises a step for calculating the angular speed of a motor (43) displacing the wire dispensing device (40) according to the wire winding step and according to the dancer error, detected by a position sensor (35) that provides an analogical signal with respect to a zero position and to a tolerance value, in order to determine the presence of a possible valley error, or of a possible peak error. In this method, if during the spool winding, a valley error or a peak error is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device (40) with the aim of filling the depression or skipping the peak.

A cable guiding assembly is mounted to a cable guide seat and for extension of a cable therethrough, and includes first and second housings, a pivot connecting unit and a locking mechanism. The pivot connecting unit includes first and second pivot connecting portions disposed on and pivotably connected to the first and second housings, respectively, such that the first housing is pivotable relative to the second housing between a close position, where the first and second housings cooperatively define an accommodating space and permit the cable to extend therethrough, and an open position that permits the cable to be installed to and removed from the cable guiding assembly. The locking mechanism includes first and second locking units disposed respectively on first and second housings, respectively opposite to the first and second pivot connecting portions and detachably engaging each other to secure the first housing at the close position.
