Winding machine for packages'

The invention relates to a winding machine for cross-wound bobbins with a shaft that carries and drives the bobbin a pad guide device moved by a gear.

There are known winding machines for cross-wound bobbins in which on the outside of the roll a thread guide is moved back and forth. The thread guide is driven by a gear that depending on the desired. Winding type switchable or changeable is. The thread guide must be adapted to the thread thickness, has to be exchanged when changing the thread size.

In the case of a cross-wound bobbin, it is known that the thread becomes helical

wound up. In order to achieve this even at a high winding speed, the thread guide must be activated correspondingly quickly be guided along the outside of the roll. The deflection at the two ends of the path of the path guide must also be very important can be done quickly · The required in the known winding machines rapid to-and-fro movement of the pad guide limits the performance of this machine. In particular, because the movements of the trail leader are not harmonious, great acceleration and deceleration forces occur on. The machine runs rough and the noise is considerable.

The invention is intended to create a winding machine for cross-wound bobbins which avoids the disadvantages of the known machines and in particular the performance of the machine no longer depends on the drive options of the trail leader.

To achieve the object of the invention, the invention is based on a winding machine for cross-wound bobbins with a shaft that carries and drives the bobbin and one of a gear; moving thread guide device, which essentially moves the thread on the outside of the bobbin;. parallel back and forth leads j and delivers to the coil. The invention is characterized in that the thread guide device consists of a rotating,! cylindrical, wide and parallel to? The sheath arranged in the winding axis consists and the mutually facing edges of the sheath parts form a ring shiita guiding the thread, the ₍

ι 1098 20/0174 ■ j

axial extension corresponds to the coil width.

The invention thus provides the known, loop-like thread guide replaced by a two-part jacket, the slot between the two jacket parts having the task of Takes over the thread guide. During one revolution of the jacket, it guides the thread back and forth and, by appropriately shaping the annular slot, lets it between the two jacket parts the desired thread guide can be achieved.

The main advantage of the machine according to the invention is that the machine no longer has any parts moving back and forth owns. Only the thread is guided back and forth. The parts leading the thread rotate evenly. The drive gear for the coat is accordingly simple. '

The machine according to the invention gives very high winding capacities, The winding capacity is no longer limited by the machine's components, but only by the strength of the thread to be wound.

Another advantage of the machine is obtained by the fact that the point of contact of the thread on the ring slot changes continuously during the rotation of the jacket. As a result, the wear is distributed over a relatively large area and is hardly noticeable. With the known, loop-like thread guide, on the other hand, the thread cuts in quickly, so that the thread guide has to be replaced frequently.

Another advantage of the invention results from the fact that the same jacket can be used even with threads of different strengths. For this purpose, it is only necessary, as the OF INVENTION dung Welter provides for the axial separation of the two Man- ■ daft telteile changeable 1st to thereby adjust the ring slot of the thread thickness · In the known FadenfUhrungseinrichtungen other hand, had to be at a change of the yarn thickness of the yarn guides also exchanged .

According to a further feature of the invention it is provided that guide elements for the thread are provided in the region of the lateral surface which prevent the thread from being carried along by the rotating jacket, a ^ parallel movement of the thread however allow. The two jacket parts are in particular over a transmission coupled together.

In a preferred embodiment of the invention, the jacket is arranged such that it surrounds the coil. An arrangement of the jacket parallel next to the bobbin is also possible, in which case the thread would then be introduced in the jacket axis and guided out of the jacket and onto the bobbin through the annular slot . The embodiment of the machine in which the jacket surrounds the coil is, however, to be preferred, since this can be achieved by a more compact design of the machine .

It is favorable if the distance between the two jacket parts can be changed not only in the range of the different thicknesses of the threads to be wound, but also if one jacket part is pulled off relatively far from the other jacket part .
