Embodiment Construction

Turning now to the figures, and in particular to FIGS. 2-3, a front and side view of a cabling assembly (20) according to one aspect of the present invention is shown. The cabling assembly (20) of the present aspect includes a frame such as the metal support frame (22) shown. Mounted to the support frame (22) is a capstan drum assembly (24). The capstan drum assembly (24) may have any number of wire pairs wound thereon for producing a cable. For example, in some aspects the capstan drum assembly (24) has as few as two wire pairs, in others it may have as many as twenty-five pairs or more.

The capstan drum assembly (24) is coupled to a capstan drum drive motor (26) that provides rotational power to the capstan drum assembly (24). The capstan drum assembly (24) and the capstan drum drive motor (26) are commercially available from a variety of sources.

The capstan drum drive motor (26) is controlled to provide the wire pairs from the capstan drum assembly (24) to a dancer assembly (...

Abstract

A method for precisely controlling the tension of a cabling assembly includes applying a triple-feedback-loop to allow the manufacture of a large number of cable pairs. The control loop may be used with any take-up and payoff assemblies and compensate for wide variations in take-up reel weight, cable weight, process line speeds, and pay-off tension. One of the loops of the triple-feedback-loop is under-damped and unstable and allows the control loop to compensate for the wide variations without changing control systems or cabling apparatus.

Description

BACKGROUND In today's modern environment, it is common to find communications-grade cable running by the mile through buildings, between cities, and even across oceans. Communications cables and other miscellaneous cables are found in nearly every household and building to facilitate the transfer of information, images, and other data across any distance at ever-increasing speeds. Apparatuses for manufacturing communications and other types of cables of various kinds have been known for some time. One well-known method of cabling is the use of a capstan / dancer / pay-off reel assembly. According to a conventional capstan / dancer / pay-off reel assembly (2) shown in FIG. 1, a plurality of wire pairs (4) are wound on a capstan drum (6). The wire pairs (4) are usually unwound from the capstan drum (6) and introduced through a dancer (8). The dancer (8) is usually a movable roller or set of rollers that applies a constant tension to the wire pairs (4). The dancer (8) may also cable the wire...
