Abstract: A woven fabric for reinforcing a resilient material, such as a tire casing, wherein the warp of the fabric consists of substantially unstranded wires held together in spaced groups by the weft of the fabric with at least some of the wires being formed with a set so as to have undulations along their length to thereby improve the adhesion between the wires and resilient material as well as to improve the tensile and compression stress characteristics of the wires. The amplitude of the undulations may be perpendicular to the general direction in which the groups are spaced from each other. The undulations may also be periodic with the phase of such undulations being either the same or different between adjacent groups.

Abstract: A metal cord consisting of at least 15 filaments, comprising a core of 2 to 4 filaments twisted together, an intermediate layer wound on the core and in contact therewith and an outer layer of filaments wound on the intermediate layer and in contact therewith, wherein the intermediate and outer layers each have a free space of from 14 to 25%, preferably 20 to 24%.

Abstract: A winding apparatus for winding wire onto bobbins including a support member for first and second bobbins and means for rotating the support about an axis parallel to that of the bobbin for moving the bobbins into alignment with the bobbin shaft, and means for laterally moving the bobbins from the carrier onto the bobbin shaft as well as from the shaft onto the carrier, so that a full bobbin may be removed from the bobbin shaft, the carrier member rotated so as to bring an empty bobbin into alignment with the bobbin shaft and then for moving the empty bobbin onto the bobbin shaft so that it may be wound with wire.

Abstract: At least two conductive wire elements which are separated from each other by a thin insulating layer such that as soon as a pressure is exerted on the composite wire at least one of the electrical characteristics, contact resistance and/or capacitance between the elements, changes to a measurable extent. A fence constructed of such composite wire has a circuit connected with both conductive wire elments for detecting any deviation in the nominal value of contact resistance and/or capacitance between them and for controlling an alarm circuit responsive to such deviation.
