A normal loom will one generally in the axial direction of the wearer the weft from a Kötzer or a weft spool arranged drainage point, a turning device for deducted, the diameter of which at most approximately Drive a winding member around the axis of 4.5 cm.

The invention is that in a Wik- Da the tape speed through the supply source The body made of a plastic tape with in one is controlled, can be a sufficient control of the Directional turns for each winding tension by a slip drive to the winding turn an average of one can be achieved through local management. An equivalent harvest embodied twisting winding is present, but can also result in other ways, for example between which relatively long lengths of wise by using an electric motor with untwisted tape. The constant torque for the drive should preferably be achieved local folds may be present in pairs and between. A slip drive is preferred the pairs seen a length of untwisted tape before transmission of the drive through a slip clutch be. This is achieved according to the invention, but the slip can occur in the drive achieved that for winding a tape winding source itself, d. H. occur with an air drive. There kels the tape between the first and second digits the linear speed of the tape in general a conical path with the tip at the first nen remains constant during the winding, must The point at which the rotation is inserted revolves along with the speed of rotation of the winding guide and periodically compress into local folds due to changes in the diameter of the winding of the twisted band must be changed at the first. The drive to the leadership must Digit is converted. The new device to make this possible of course. Winding up of the bobbin contains one in which after leaving the trigger guide the runs The tape to be wound folds spaced tape to the rotating device, and its first surface on the rotating device, which is opposite 20 point of contact with this is an intermediate point. It whose axis is offset with that of the drain - it has been found that if the distance is between two parts at an angle on a conical path see the drain guide and the point of contact supplied tape is in engagement, and the dis- abled is kept relatively short, this is the uprising of the outlet in relation to the maintenance of a regularity in the threshing the drainage point and the winding point briefly supported 25 hung.

A number of other factors are also included in tension in the band between the vent and that of the control of the introduction of a twisting surface within certain limits. hold, and the relative importance of these ver- according to The present invention will thus change with the embodiment of the use a source of supply with a particular device and employment relationships. Of the Synthetic plastic peeled off at the speed - the most important factor is of course the tension tied into a roll by winding the tape into the tape, the effects of which have already been discussed has been on a non-rotatable carrier by means of a rotating. Other important factors are the deformed device, which has a device for the diameter of the drain guide and the angle of the contains the tape driven about the carrier axis by the tape exiting the drain guide becomes, so that in this way a begotten cone. It has been found to be advantageous unscrewing turn placed in the tape with each revolution that this angle has a considerable size. the leadership is introduced. The tape is made by properly shaping and positioning the drain coil guide in a generally axial line guide or an associated part with reference direction of the drain guide with such a chip 4 ° on the cone angle of the belt, it is possible fed that twist on controlled lent turned out to control the nature of folding, Manner is carried out. The consequence of the insertion which results from the introduction of a twist Twisting or twisting a wire while there. When using a single drain guide Winding up consists in that when the tape is late, the tape is against the guide once every time ter of the coil pushed over the same end as that, 45 turns of the coil and the resulting from it over which it is wound up, is unwound, resulting folding process in connection with the the twisting performed during winding tension in the tape leads to the formation of is removed and essentially untwisted pairs of pleats at intervals corresponding to each wick tape results. Thus, according to the invention, one revolution. In this way it is possible to use the produced winding either as a fixed 50 twist in such a way that it Weft thread feed for a loom or in the resulting winding by local for example in a slip-on creel for building up folding shows, between which relatively large in a warp thread feed, lengths of a flat or untwisted tape can be and overcomes the disadvantages described above. gene.

In other words, it is possible for the over-end to be "relatively long" deduction with the benefit of a fixed end which means that at least 50% of the total length Windings but without the disadvantages of twisting the tape untwisted, i.

In practice it is possible-how Already mentioned above, it is important to localize the span-borrowed, the wrinkles much more strongly, so The tension in the tape during winding accounts for a large proportion of the total length of the tape to keep. If the tension is too high, the shoots will stay in an untwisted shape. This is made up of two the tape on, d. H. there are longitudinal folds for reasons of importance. If first a Verdem Band, and a product is obtained which is inserted into a band and turned into a fold ches has been difficult to convert to its original state through the winding process, can be converted back. On the other hand, if the 65, there is a possibility that the Tension is too low, the twisting un-wrinkled mark will persist evenly, and also one will generally remain when the twist comes out of the band again unusable winding generated. has been removed.
