Abstract: Forming a core unit from telecommunications conductor units of twisted together conductors in which the units are first changed in relative positions laterally of their passline and then are passed between two rollers to form them into a curved array. The positions of the units in the array influence their final positions in the core unit as they move towards a core unit closure device. Hence as the positions in the array change because of the positional change in relative positions of the units upstream from the array, then the units change in relative positions in the core unit by extending backwards and forwards around the core unit axis.

Abstract: With the creel for a spinning machine according to the invention at least two rows of rotatably suspended roving bobbins, which extend essentially in parallelism with respect to one another, are adjacently lined-up. Normally in ring spinning machines there are employed for such creels roving deflecting rods which extend horizontally in the longitudinal direction of the ring spinning machine. The rovings extending from the roving bobbins to the drafting arrangements are guided around the deflecting rods for the purpose of guiding the rovings. If the deflecting rod is located behind the bobbins, then insertion of the rovings about the rods is extremely cumbersome, and additionally, there exists the danger of damaging the rovings. If the deflecting rod is located further towards the front, then exchange of the bobbins becomes tedious. These drawbacks are eliminated with the invention in that a row of substantially rod-shaped holders is arranged behind the front row of roving bobbins.
