    Abstract: Metal cord for use in reinforcing fabric for articles made from rubber, such as pneumatic tires, conveyor belts, flexible tubes, and similar, comprising a plurality of such metal cords orientated parallel to each other in a single direction and in which each cord comprises metal wires wound spirally around each other, wherein at least one of the wires of the cord consists of a shape memory material. During the phase of incorporation of the cords into the elastomeric material, the shape memory wire tends to recover the shape memorized initially and, by means of the force generated during this recovery, transmits by friction to the surrounding wires forces tending to shorten the pitch of the cord with spacing of each wire from the next, resulting in good penetration of elastomeric material between the wires. The closure of the cord is maintained in the subsequent heat cycles, owing to the memory degradation characteristics imparted to the wire. The invention is particularly suitable for fabrics forming belt layers and casing plies in pneumatic tires.

    Abstract: A sling for industrial lifting made of a load-bearing core (1) and a cover (2). The cover (2) protects the plurality of yarns (3) that make-up the core (1). Each core yarn (3) is made of a number of core threads (4) twisted together. The core yarns (3) are twisted together where the twist is in the. same direction as the individual core strands and a different direction than the twist of the cover (2). The present invention describes the method of twisting the core yarns (3) together by inserting core yarns (3) substantially parallel into a cover (2) that has a twist opposite of each core strand. As the core strands are inserted into the cover (2), the twists of the individual core yarns (3) interact with the twist of the cover (2), resulting in the core yarns (3) twisting together.
