Description

Process for preparing packages for dyeing, washing and the like. the thread package without sleeves on cylindrical dyeing spindles in the slip-on system circling fleet. The dyeing of the cross-wound bobbins common in the trade is due to the in them located winding tube, which is usually made of paper or cardboard, makes it difficult. Man has therefore tried to manually or mechanically remove the winding tube for dyeing to remove the thread winding of the cheeses and through tubes made of other material or of small diameter or to be replaced by elastic sleeves. The one Sometimes the paper tubes should be exchanged for metal tubes because the latter are more suitable for the dyeing process. The other time the pods were on which the yarn was wound, through sleeves or tubes of smaller diameter replaced in order to loosen the inner yarn layers of the packages and so that To facilitate penetration of the liquor also through the inner core of the coils. the Replacing counter-elastic sleeves should be the compression of the cheeses when dyeing in the packing system and thereby the annoying gaps between remove the packed packages.

In all of these attempts, however, it has been found that the Removal of the sleeves, which is generally the case with the so-called solar coils with wooden sleeves is common with cross-wound bobbins because of the long contact surface and the small diameter the sleeve - common sleeves are, for example, 145 mm long and r 4 mm in diameter - untunli.ch is because it messes up the inner walls of the yarn and preventing the sleeves from being reintroduced after dyeing. For elimination this drawback has also been suggested, the yarn prior to ejection and prior to reinsertion of the sleeves by means of complete desiccation To fix heat. This means, too, apart from the inconvenience, is unsuitable for the confusion of the internal threads during expulsion and reintroduction to prevent the pods. Attempts have also been made to open the yarn! From the start To wind special sleeves made of resilient steel wire. The yarn was on the wire cylinder in an expanded state - a corresponding one was required to stretch the cylinder apart Wooden roller inserted - spooled. After spooling, the sleeve was made by overlapping the ends slightly curled up to that. Purpose created while winding the thread To eliminate tension of the yarn and thereby the remaining on the elastic sleeve To make yarn more permeable to the liquor. However, this device has the disadvantage that expensive special sleeves must be used from the start, and that the sleeves remain in the yarn during dyeing. On the other hand, there is Process for preparing packages for dyeing, washing and the like without sleeves according to the invention on cylindrical dyeing spindles in an attachment system with rotating liquor in that the yarn is designed to be variable in diameter and resilient Winding core wound with a widened diameter, with the normal diameter the The winding tube is pushed onto the dyeing spindle with a smaller diameter and when it is narrowed Diameter pushed back into the latter after dyeing the sleeveless thread lap will. Here, a winding tube with a variable diameter is used, which allowing the yarn to be withdrawn without any damage and out of the ordinary Paper or cardboard can be produced by rolling it up without gluing, because. it does not remain in the bobbin during dyeing and the like.

In this regard, it is noted with reference to the drawing: Fig. I shows a winding tube i suitable for the new device with its normal diameter, d. H. with the diameter of their manufacture. It consists of a cylindrical rolled up paper or metal strips with overlapping edges. the Sleeve is expediently made resilient in order to handle it without tools can.

Fig. 2 shows the winding tube i expanded to the diameter larger winding machine spindle 2 attached. With existing winding spindles with no If the diameter is sufficient, a chuck is used to expand the winding tube. When the finished cheese is withdrawn from the winding spindle 2, the winding tube jumps i back to its normal diameter so that the tube i is detached from the thread package 3 loosens and the latter from the tube without damaging the inner thread turns can be pushed onto the cylindrical dyeing spindle. To make it easier to procrastinate The latter can be fitted with a removable centner pin on the dyeing spindle will.

Fig. 3 shows the winding tube i with its normal diameter the cylindrical dye spindle 4 inserted.

Fig. 4 shows the winding tube i rolled up in the dye spindle 4 plugged. The dyed thread lap 13 sitting loosely on the dye spindle can be Slide it onto the sleeve i, which is smaller in diameter, without damage. After losing weight the sleeve i jumps from the dyeing spindle 4 to its normal diameter Yarn, so that the further processing of the dyed cheese on the tube is over can be performed.

Claims (1)

PATENT CLAIM: Process for preparing packages for dyeing, Washing and the like of the yarn package without sleeves on cylindrical dyeing spindles in the attachment system circling liquor, characterized in that the yarn on one in diameter variable and resilient winding tube (i) with a widened diameter spooled (Fig. 2), with normal diameter of the winding tube on the dye spindle (4) of smaller diameter pushed (Fig.3) and at. narrowed diameter After dyeing the bobbin-less thread package is pushed back into the latter (Fig.4).
