Problems solved by technology

[0003] A disadvantage of the upper apron holders disclosed in the prior art is that the amplitude of the raising and lowering movement of the turning edge on the apron guide with respect to the horizontal plane is greater than the amplitude of the manufacturing-related play between the guiding journal and the channel.

Embodiment Construction

[0026] figure 1 The illustration in FIG. 1 shows an upper apron carrier 1 comprising a middle part 2 and two apron guides 3 . The intermediate piece 2 is mounted on the shaft 5 of the double top roller 6 . The double top rollers 6 are held in a known manner on the guide rods of the top roller carrying and pressing arms. The apron guide 3 is associated with two rotatably mounted top rollers 6 .

[0027] A top apron, not shown, surrounds the top roller 6 and the apron guide 3 . Here, the upper apron is guided by the apron guide 3 and deflected at the deflection edge. The running path width of the apron guide 3 is limited by the partition wall 4 set perpendicular to the direction of movement of the upper apron on the apron guide 3, as from Figure 1 to Figure 3 As can be clearly seen, this prevents the top apron from slipping off the apron guide 3 . In order to tension the upper apron, the apron guides 3 are acted upon with a spring force generated by a spring 7 arranged bet...

Abstract

The holder (1) has an upper apron stretched by elastic force, and a strappy guide (3) turned on a bending edge (16) and clamped on an intermediate section (2). A guidance plate (12) is arranged on the intermediate section as a guidance groove (11) that is carried out continuously, where the plate is arranged on the strappy guide on an outer side of a track width of the upper apron, and guides a pair of guide parts of the strappy guide. A short side of the guidance groove is arranged on an outer edge of the intermediate section.

Description

technical field [0001] The invention relates to an upper apron carrier for a drafting device of a spinning frame, which has at least one spring-loaded apron guide which tensions the upper apron and deflects it at a deflection edge. part, the apron guide is held on the middle part of the upper apron holder. Background technique [0002] German utility model patent document DE 92 14 598 U1 discloses a top apron carrier as described in the preamble of claim 1, which has an apron guide that tightens the top apron and deflects it, The apron guide is held on the middle piece of the upper apron carrier. The apron guide is spring loaded in order to hold the upper apron at a defined tension. For guiding the apron guide, the apron guide has shaped journals which are guided into corresponding channels formed on the intermediate piece. According to DE 92 14 598 U1, the journal and the channel are arranged within the width of the path of travel of the top apron on the apron carrier or...
