Definitions
- the invention relates to a yarn laying device for use in the manufacture of a wound with a yarn, preferably designed as a cheese package, with a rotatable by means of a drive about a rotation axis Veriegetrommel with a thread-guiding slot on the
- Cylinder surface of the laying drum wherein the axis of rotation is formed by a shaft with two shaft ends.
- laying Longitudinal axis, ie the stroke of the yarn package, the yarn package are reciprocated, so that a traversing movement is performed.
- the latter is called laying.
- laying drums it is known to use so-called laying drums.
- the laying drum is with its axis of rotation parallel to the longitudinal axis of the yarn package in the yarn path in front of the yarn package in the
- Thread laying device arranged.
- the thread is guided in a zigzag-shaped slot in the cylinder-like surface (cylinder surface) of the laying drum and running the axis of rotation forming shaft tangentially through the laying drum therethrough.
- the thread is thus applied to the shaft.
- the yarn is reciprocated over the length of the longitudinal axis of the yarn package as far as the slot extends correspondingly in the longitudinal direction of the longitudinal axis.
- the type of winding, ie the Aufspul characterizing is thus determined by the shape of the slot.
- the shaft is mounted on both shaft ends on the thread laying device, usually via ball bearings. So it is a two-sided storage of the laying drum used.
- the two-sided storage of the laying drum leads to considerable installation effort in disassembly of the laying drum for their cleaning or to replace the laying drum to use a laying drum with a different Aufspul characterizing.
- different basic components of the laying drum must be used for different strokes, as always the entire length between the mounting points of the shaft must be bridged to the thread laying device to the two-sided storage.
- the drum must be cleaned so that, for example, a light yarn is not contaminated by the deposits (lint, softening etc.) of the previous yarn.
- the invention has for its object to provide a thread-laying device which avoids the disadvantages of the prior art, in particular, a rapid change of Aufspul characterizing should be possible.
- a thread laying device for use in the production of a yarn package wound with a yarn, preferably a cross-wound bobbin, has a laying drum rotatable about a rotation axis by means of a drive with a thread-guiding slot on the cylinder surface of the laying drum.
- the axis of rotation is formed by a shaft with two shaft ends.
- one of the shaft ends is designed as a mounting shaft end such that the shaft is mounted with the mounting shaft end of the yarn laying device.
- the second shaft end is designed as a free shaft end.
- the shaft is therefore mounted only on one side, so that a one-sided storage, i. a one-sided clamping of the laying drum is formed.
- the shaft can be formed, for example directly from an electric motor in extension of the motor shaft of the electric motor or it can be provided a rotatable mounting of the shaft, so that the drive, for example as a belt drive can be trained.
- the well can also be rigidly mounted, so that only the laying drum is rotatably mounted on the shaft. By only one-sided installation of the laying drum this is easy and quick to disassemble and / or interchangeable, for example, to change the Aufspul characterizing with respect to the stroke of yarn packages.
- the laying drum must therefore have no windows in the cylinder surface of the laying drum. A cleaning can be made without much effort in dismantled laying drum. If no windows are present in the cylinder surface can be dispensed with a safety housing. In the laying drum according to the invention can therefore be dispensed with a door because no rotating openings must be present.
- the laying drum according to the invention has a hollow shaft, wherein the hollow shaft, preferably via ball bearings, is mounted rotatably mounted on the shaft.
- the hollow shaft is preferably pushed onto a rigid axle as a shaft and rotatably mounted thereon.
- the shaft can be rigidly mounted on the thread laying device, so that it forms a rigid and stationary, very stable axis.

- the laying drum preferably comprises a first drum half arranged at the end of the assembly shaft and a second drum half arranged in the region of the free shaft end, the drum halves respectively forming partial surfaces of the cylinder surface of the laying drum.
- the thread-guiding slot is formed by a gap separating the partial surfaces.
- the two drum halves can be easily disassembled to make eg a cleaning of the inside of the laying drum.
- the montage shaft end side arranged first half drum is fixedly connected to the hollow shaft, preferably screwed, and the second drum half is pushed onto the hollow shaft and rotatably connected to the hollow shaft with the hollow shaft. Such a flying storage of the laying drum is realized.
- the second drum half can be removed and then the second drum half can be pushed down together with the hollow shaft of the shaft.
- the second drum half is fastened on the hollow shaft via a quick-release mechanism, whereby the removal of the second drum half is further simplified, in particular for cleaning purposes.
- the quick release mechanism can also serve to adjust the gap width of the thread guiding slot.
- Such a quick release mechanism may comprise a screwed onto the hollow shaft with a screw thread ring, wherein the screw thread is formed on tiltably attached to the ring jaws.
- the gap width of the thread-guiding slot can be determined by means of the thickness and / or the number of spacer elements.
- the laying drum according to the invention can be flexibly adapted to different thread thicknesses.
- the partial surfaces of the cylinder surface formed by the drum halves and / or the end faces of the laying drum are advantageously designed to be free of openings. The drum surface is therefore closed, ie it has no opening for cleaning. This minimizes the risk of injury from the laying drum.
