Abstract

Bei einer Litze (6) ist der schmale Litzenschaft (21) zu Lasten der Endösen (7, 8) und des Fadenaugenbereichs (29) verlängert worden. Dies ist einerseits durch Verkürzung der Endösenbereiche (7, 8) auf ihr absolutes Minimum und andererseits dadurch geschehen, dass dem Transport der Litzen dienende Hilfsöffnungen (38) näher an die Endösen (7, 8) herangelegt worden sind. Die Radien R im Bereich der Endösen (7, 8) sind vermindert Der Litzenschaft (21) hat statt der üblichen 2 mm Breite noch maximal 1,6 mm. Die über die Endöffnungen hinausragenden Bereiche (14, 13) der Litze (6) weisen statt der üblichen Länge von 4 mm noch 2,5 mm bis 3 mm auf. Direkt um das Fadenauge (33) weist die Litze eine Breite auf, die wie bisher dem doppelten der Breite des Fadenauges (33) entspricht. Die Länge dieses Bereichs ist aber auf maximal das Doppelte bis Dreifache der Fadenaugenbreite verkürzt. Der Übergang von der schmalsten Zone (27, 28) des Litzenschafts (21) zur vergleichsweise breiten Zone (29) um das Fadenauge (33) herum ist durch einen längs gestreckten Übergangsbereich (34) charakterisiert, der maximal 1,8 mm Breite aufweist und der Verstärkung dieses Bereich gegen mechanische Belastungen dient.

Figure 00000001
In the case of a stranded wire (6), the narrow strand shank (21) has been extended at the expense of the end eyelets (7, 8) and the thread eye region (29). This is done on the one hand by shortening the Endösenbereiche (7, 8) to its absolute minimum and on the other hand by the fact that the transport of the strands serving auxiliary openings (38) closer to the Endösen (7, 8) have been herinzegt. The radii R in the region of the end eyelets (7, 8) are reduced The strut shaft (21) has a maximum of 1.6 mm instead of the usual 2 mm width. The regions (14, 13) of the strand (6) projecting beyond the end openings still have 2.5 mm to 3 mm instead of the usual length of 4 mm. Directly around the thread eye (33), the strand has a width which, as hitherto, corresponds to twice the width of the thread eye (33). The length of this area is shortened to a maximum of twice to three times the yarn eye width. The transition from the narrowest zone (27, 28) of the Litzenschafts (21) to the comparatively wide zone (29) around the thread eye (33) is characterized by an elongated transition region (34) having a maximum of 1.8 mm width and the reinforcement of this area is used against mechanical loads.
