Abstract: A cable manufacturing method comprising the steps of arranging a closing die and a plurality of panel plates in this order, on a pass-line having a curved zone and a linear zone, from the side of a front end of the pass-line, inserting all wires, to be stranded, through an opening of the closing die, and inserting each wire through a hole formed in a corresponding one of the panel plates, guiding the wires such that the wires are substantially parallel with one another and each wire is loose of the panel plates, rotatably supporting the panel plates, respectively, and passing each wire through the curved zone and the linear zone while rotating the panel plates in the same direction, thereby stranding the wires with a large pitch so as not to plastically deform the wires.

Abstract: An optical fiber dispensing system (30) includes a canister (42) within which an optical fiber (12) is wound, and a helix dampener (40) that reduces the helical diameter of the optical fiber (12) as it is paid out from the canister (42) along a payout axis (20). The canister (42) is either a cylinder or a slightly tapered cone. The helix dampener (40) is a structure overlying the payout end of the canister (42) and extending beyond the canister (42) along the payout axis (20). The interior surface of the helix dampener (40) defines a locus (36) of points whose distance from the payout axis (20) decreases with increasing distance from the canister (42), to an opening (38) through which the optical fiber (12) is dispensed.

Abstract: Machine for continuous twisting and cabling of filaments of the type including a predetermined number of work positions disposed on a common support frame (4), each work position including, taken in order according to the process of transformation of the filaments:a feeding and twisting section (1) for each of the elementary filaments, on each side of the machine;means (2) for the return and joining of a predetermined number of elementary filaments thus twisted and;a cabling and winding section (3);characterized in that the cabling and winding section (3) is common to the two feeding and twisting sections (1) and is constituted by spindles disposed side by side in the vertical plane of symmetry (AA) passing between the two feeding and twisting sections (1).

Abstract: A core unit and method and apparatus for making it in which conductor pairs or units having a single direction of twist and in which angles of twist lay change along lengths of the conductor pairs. In a preferred and practical construction, the angles of twist lay of all pairs change along their lengths on a continuous basis. This angle change is cyclical and with the cycles of the angles of the pairs being out-of-phase with one another. This achieves average twist lays of the units which are substantially equal to one another from conductor pair-to-pair. The structure is achieved in a tandem operation of twisting conductors into pairs and then forming them into the core unit, preferably by stranding.
