Abstract: A stranding of long winding material using a substantially cylindrical rotary body. The rotary body includes a first passage for guiding a first winding material through the cylindrical rotary body and a second passage for guiding a second winding material through the cylindrical rotary body. The first passage connects a first offset inlet on a first end side of the rotary body to a first offset outlet on a second end side of the rotary body, which opposes the first end side. The second passage connects a second input, arranged on a surface of the rotary body extending between the two end sides, to a second offset output on the second or first end side of the rotary body.

Abstract: Production of a reinforcement mesh comprising reinforcement bars (3), which are tied together by means of twisted wires (1, 2), may take place according to the invention by a method wherein two wires (1, 2) are rolled up on their respective wire coils (4, 5), which are mounted opposite each other on a rotatable shaft (12), and wherein each of the wires is guided by a wire guide element (6) downwards in a direction toward the common twisting point of the wires (1, 2). Meshes of surface-treated, coated, wires and bars may be made in this manner, there being no external impact that can damage the surface.

Abstract: An exemplary apparatus is a jig including a chuck having a plurality of radially movable members for controllably gripping a member inserted in an axial bore extending therethrough. The chuck is mounted on a hollow tube whose axis is collinear with the bore of the chuck. This jig is used by first positioning a first elongated member (e.g. a first, or "inner" wire) in the axial bore of the chuck, and tightening the radially movable members thereon. The distal end of a second elongated member (e.g. a second, or "outer" wire) is secured in a fixed relationship with the chuck, so that the distal end turns with the chuck. The chuck is then rotated so as to rotate the first, inner wire. As this inner wire is rotated, the operator trains the second wire thereagainst, thereby yielding a length of coil with the inner wire extending therethrough.
