A method for manufacturing a straight steel monofilament for the reinforcement of belt ply of a pneumatic tyre, where the arc-height of the straight steel monofilament is less than 30 mm. The steel monofilament is plastically deformed by a twisting along the axis of the steel monofilament on a double-twist apparatus. The plastic twist deformation eliminates the surface stress difference on the steel monofilament and provides a straight steel monofilament for belt ply reinforcement. This provides a simple solution with existing apparatus to manufacture straight steel monofilament suitable for tire reinforcement with high speed for mass production.

A jacket substantially retains the tension member. A method of forming a tension member for an elevator system belt includes arranging a plurality of fibers into a fiber bundle. The plurality of fibers extend parallel to a length of the belt and have one or more lengthwise extending gaps between lengthwise extending fibers. The plurality of fibers is bonded to a first polymer matrix.

An object is to provide a wire straightening device and a wire straightening method, with which it is possible to automatically set the roller spacing in accordance with the type of the wire and to further adjust the roller spacing during operation. A wire straightening device (20) includes a preset value obtaining device that obtains a preset value of roller spacing, which is predetermined for each type of wire (2); a roller spacing automatic setting device that drives an actuator (26a) so that the roller spacing becomes equal to the preset value when the type of the wire (2) is input; and a roller spacing changing device that changes the roller spacing based on an operation by the operator while retaining the preset value during operation of a wire processing device (1).
