"with tapering End-share "

The innovation is seen in the twine package * which you can see on both Sides taper, i.e., on spools of thread., «They on a tube-like Core are built up and a ** 'gyl-Indian middle part as well as from the respective ends of the central part; on the surface of the have conically sloping end parts »

Such-parnwicteel with double-sided ?@rjilngu.og are wound up by ■ Streoktwistmasehinen for synthetic thread yarns, whereby a loop and loop is used "~ Meohanisraus" The traversing of the ring is programmed in such a way that-a-thread lap of the desired Form arises «A -such a construction program, which is currently used extensively., Consists d

the length of the traversing stroke of the ring rail is gradually reduced during the build-up from a maxiraali length® on the core to a minimum length on the outer layer of the middle part of the thread roll® «

Although this type of tapered on both sides of yarn packages is extensively using _s had to be found that during handling and during transport to the shoulders, dii. to the. Connection points between the tapering end parts and the cylindrical central part "the thread package is easily damaged" The reason for this is that these connection points are sharp-edged.

Object of the present innovation is _s create a yarn package ^ u, the non besitgt this power rush.

Thus, the Heuerung is provided a both sides tapered yarn package according whose -Changlerungshub gradually decreases with the thickness of the reel>"characterized in which the length of each -second Changierungshubs within the lufbauprograraras does not decrease" Instead of-a-gradual decrease in Changierungshublänge that during of the entire build-up of the thread bobbin takes place, every two traversing stroke is longer than it should actually be, while the traversing stroke in between has the correct length according to the build-up program.

The effect of this shift in the reversal points be stands in the fact that the original home oil is broadened and as a result whose shoulders of the wrap are rounded

An expedient procedure * by which the renewal according to Winding of yarn can be made, consists of * relay between a traversing stroke limit switch of the cam-programmed electrical reversing system and the RingbaBkuakehr ¥ ®ntil one to switch on the hydraulic installation armature «.

The Cfoangierungshubendsohalter is moved according to the "decreasing stroke length, which is dictated by the Aufbaunoetcen fö. However, since the electrical circuit includes the same and the Rlngb & nkumkehrventll a pulse relay and a timing relay and because the pulse relay itself is programmed in such a way that it is only on the timing relay A springy second impulse acts, the effect of _{a is} that the ring rail according to the set time delay only reversed every second time after a longer stroke than the actually programmed stroke length ©, ie a few millimeters later

The time delay can be set in the range from O ₅ IO to I ₅ OO seconds, with the accuracy being within 0.01 seconds.

In the accompanying drawing a known (Figo 1) and a new ungsgesßäß he (Fig. 2) yarn package is shown.

On a tube-like core 1, a winding of yarn is built up, which has a cylindrical central part 3 and then two conically tapering parts 2. In Figo 1 the transition (the shoulder) between these parts is sharp-edged, while in * Fig. 2 (according to the innovation) the transition is rounded
