    Abstract: In a winding machine provided with a common bobbin holder for mounting a plurality of bobbins thereon at respective winding positions, a traverse mechanism provided with a plurality of working units, a plurality of fulcrum yarn guides disposed at respective positions above the traverse mechanism, means for collecting a plurality of yarns fed via the respective fulcrum yarn guides, means for displacing the collecting means along the common bobbin holder from a stand-by position to the supporting side of the bobbin holder, a yarn introducing and take-up device is additionally mounted on the machine so as to separately introduce the yarns one by one to the corresponding working units of the traverse mechanism while displacing the collecting means after collecting the yarns fed via the respective fulcrum yarn guides, the introducing and take-up device is provided with a yarn introducing guide disposed at a position between the fulcrum yarn guides and the traverse mechanism in a parallel condition to the bobbin holder, this yarn introducing guide comprises plural guide units with an intervened space between two adjacent guide units by which the above-mentioned selective introducing of each single yarn to the corresponding working unit of the traverse guide can be attained.

    Abstract: An improved magnetic recording medium comprising a flexible support consisting of at least about 70 mol % of p-oriented aromatic polycarbonamide units. The polycarbonamide may include substituent groups on the aromatic nuclei. The support has a density of more than about 1.41 g/cm3 at 25 DEG C and 0% relative humidity, and a tensile modulus higher than about 800 kg/mm2 in at least one direction, combined with a thin layer of magnetically susceptible material deposited electrically or dispersed in a nonmagnetic binder. The magnetic recording medium in this invention shows excellent running performance and has superior dimensional stability both thermally and hygroscopically.

    Abstract: A yarn twisting apparatus comprises a spindle which holds and rotates a bobbin for winding a yarn, an annular ring encircling the spindle, a ring holder movable with relative reciprocating motion axially of the spindle, having fluid nozzles and supporting the ring. A magnetic force is applied between the ring and the ring holder. The ring is supported and stabilized without coming into contact with the ring holder by the repulsive force of the fluid jetting out from the fluid nozzles and by the attractive magnetic force.
