Abstract: A composite yarn comprising a component of staple fibres and a component formed by a continuous strand is spun on a friction spinning apparatus. Staple fibres are fed to a twisting zone where the fibres are twisted to form a staple strand with one end open.

In this way a yarn is formed with some fibres forming an inner core twisted with the continuous strand, with some fibres forming on outer sheath around the core and continuous strand and some fibres having part of their length in the core and part in the sheath.

Abstract: A radial spare tire which, upon inflation, stretches from a shape having a reduced diameter adjacent the wheel rim on which the tire is mounted, to a regularly sized radial tire which the spare tire is designed to replace. The tire is molded and vulcanized in an unstretched configuration of reduced size. The stretching of the tire is made possible by the utilization in the carcass and belt plies of reinforcement cords which, during the processing of the cord and building of the tire, have a relatively high modulus of elasticity. When the cords are subjected to vulcanization temperatures, they lose their strength and have a low modulus of elasticity to permit the stretching of the tire to a regular size. The cords then develop a high modulus of elasticity in the stretched condition to provide the required reinforcement of the tire in the inflated regular size condition.

A further embodiment comprises the bundle of twisted monofilaments and a synthetic binder in thin band form spirally wound in the direction of the core bundle twist so as to provide a flat twine useful as cable filler.
