Embodiment Construction

[0041] figure 1 The left half of the creel 1 of the ring spinning machine is shown. On the other side of the center line 2 shown in dashed lines, the creel has a mirror-symmetrical right half, not shown. In such a creel, four guide rails 4 are arranged on the carriage 3, which extend along the entire length of the creel, and the suspension holders 6 for the roving bobbins 7 can be mounted in these guide rails by means of rollers 5 move. The suspension cage is connected to the suspension carriage via longitudinally extending rods 8 and can move together. Four rows of roving bobbins 9, 10, 11 and 12 are formed by a plurality of suspension train groups.

[0042] Between the two rows 9 and 10 on the outside of the roving bobbin 7 and between the two rows 11 and 12 on the inside, a roving unwinding guide 13 is respectively fixed on the bracket 3, and the roving unwinding guide 13 is used for The roving 14 unwound from the roving bobbin 7 is guided. Below these roving unwinding...

Abstract

The aim of the invention is to dispense with roving feed hooks that can be exchanged on suspended carriage trains introduced into a creel (1) of a ring spinning machine. As a result, roving unwinding guides (13) are fixed to the creel. The roving unwinding guides (13) respectively guide two roves (14) unwound from the roving bobbin (7). In order to prevent the two roves that are guided through said type of double rove unwinding guide from being mutually impeded, the roving unwinding guides (13) are provided with two roving feed hooks (27) that are mutually offset about small distances (28, 29) on two planes (25, 26). The roving unwinding guides (13) are arranged between the two outer tracks (9, 10) and between the two inner tracks (11, 12) of the roving bobbins on a creel (1) comprising four rows (9, 10, 11, 12) of roving bobbins (7).

Description

Background technique [0001] EP 0 287 788 B1 already discloses a creel for a ring spinning machine, which creel has a plurality of guide rails for moving in and out a suspension train with roving bobbins. In this case, an additional guide rail is provided compared to the number of guide rails that unwind the roving bobbin and extend to the drafting device. If the unwinding of the roving bobbin of one of the guide rails has already been completed, or is completed soon, the unwinding of the roving is transferred to the full roving bobbin of one of the other guide rails. These rails then serve as unwinding rails cyclically. Remove the unwound suspension train of roving bobbins and replace them with suspension trains with full roving bobbins. [0002] The roving bobbin holder of the suspended train group is provided with a roving unwinding guide for the roving, which is arranged on the suspended train group and moves together with it. Since there are significantly more suspensio...
