摘要:
Forming a telecommunications cable core unit in which conductor pairs change their relative positions along the core unit. The conductor pairs, as they are fed towards a core-unit forming device, are passed through individual guides which are movable independently of each other laterally of the feedpath of the conductor pairs and within certain confines. A fluid force is used to cause this guide movement. The fluid force may be the force created by an air flow, in which case the guides are buoyant.

A presser finger for banks of spindles, that has a slot (1) opening at one end in a hole (2) for passage of the yarn (6), closed at its other end and having a transverse cross section less than the thickness of the yarn. The slot can be wedge-shaped, or it can have parallel edges smoothly machined at acute angles.

A spinning wheel having manually positionable means for guiding the spun yarn as it is wound on the bobbin to provide more even distribution of the coiled yarn along the length of the bobbin. A collar carrying a yarn guide member in the form of a hook encircles one of the arms of the flyer for sliding movement along the length thereof. A permanent magnet mounted upon the collar yieldably fixes the position thereof upon the flyer arm, which carries an elongated strip of material to which the magnet is attracted, until moved by the operator.

A grommet for leading the roving to a flyer of a roving machine which grommet is composed of an oil impervious plastic material which may be molded and which has an upwardly flaring opening with a friction means therein for contacting the roving. The conical outer surface is substantially parallel to the conical inner surface of the grommet and fins or ribs project outwardly from the outer surface of the grommet.

A FLYER FOR WINDING PACKAGES OF TEXTILE ROVING AND OF THE TYPE HAVING AN AXIAL PORTION EXTENDING IN THE OPPOSITE DIRECTION FROM THE LEGS OF THE FLYER SO AS TO BE CAPABLE OF JOURNALLING IN ONE OR MORE BEARINGS HAS THE AXIAL PORTION FORMED ALONG ITS LENGTH WITH A PASSAGE HAVING A CONFIGURATION SUTH THAT THE ROVE FOLLOWS A DEVIOUS PATH. THE RESULTANT CHARGES OF DIRECTION CAUSE THE FIBERS TO BE PRESSED TOGETHER LATERALLY THUS BINDING THEM TOGETHER AND PERJITTING CONSIDERABLY GREATER TENSION TO BE APPLIED TO
THE ROVE THUS RENDERING IT POSSIBLE TO WIND ROVE WITH VERY LOW TWIST WITH CONSIDERABLY GREATER TENSION THAN PREVIOUSLY SO AS TO FORM A FIRM PACKAGE. THE DEVIOUS PATH MAY BE FORMED EITHER BY A HELICAL GROOVE IN A CENTRAL MEMBER FITTED WITHIN AN OUTER SHELL OR BY MEANS OF A TUBE SHAPED TO A SINUOUS CONFIGURATION AND MOUNTED WITHIN AN OUTER SHELL.
