Abstract: A multi-segment roll package comprises a continuous length of plastic tape [117] wound about a core [105] resulting in a spooled roll segment [109] sandwiched between two end roll segments [107A, 107B]. A tape guide winds one or more spiral windings [113] at an end position on the core. The tape guide traverses axially at a transition pitch greater than the tape width to the beginning of the spooled roll segment position and wraps a layer of overlapping windings to the end of the spooled roll segment.

The tape guide reverses axial direction and the process is repeated to build a roll package. The end roll segments provide stability to the ends of the roll package and allow larger diameter roll packages as compared to conventional spooled rolls.

Abstract: A spool (20) which is used in the taking up and the paying out of a relatively long length of optical fiber includes two flanges (24, 26) and a hub (22) with each flange being tapered. The spool includes a collector (30) which is formed adjacent to one of the two tapered flanges of the spool and which provides access to the initial or leading end portion of the length of optical fiber which is wound on the spool. A groove (32) of the collector communicates with the hub of the spool through each of the two diametrically opposed slots (28--28) in the adjacent tapered flange (24). This allows the optical fiber to be wound on one of two coaxially mounted spools and to be transferred to the other spool with the first few convolutions being received in the groove and then passed through one of the slots in the adjacent tapered flange onto the hub.

Abstract: Tape is wound into a package by traversing the winding position along a cylindrical core such that the winding position is intermittently and repeatedly halted at a plurality of positions arranged axially of the core so that at each position the tape is wound spirally following which the winding position is traversed to the next adjacent position. The spirals comprise at least one turn and more of the winding time is spent in forming spirals than in traversing between spirals. The spacing between the positions is such that the spirals do not overlap and such that the gap between the spirals is less than the width of the tape. The number of spirals wound at each position is insufficient to cause a step which interferes with traverse back to the position. Control of the traverse movement can be achieved either electronically by a pulse counter connected to the package support shaft or electro-magnetically by a control drum driven from the package support shaft.
