DE2917792A1 - Cross wound yarn bobbin - has free end fixed by spraying surface with adhesive which is slightly tacky and readily removable by washing - Google Patents

Abstract

Bobbins may be mounted freely rotatably on a frame support provided with adhesive dispensers which apply adhesive to the horizontally disposed bobbins. Bobbin may have the whole surface covered with the adhesive. Alternatively, only the end faces or only part of the periphery may be coated with the adhesive. Used for attaching end of yarn for transport or storage after winding. Conventional packaging including wrapping in shrinkable foil whose removal may lead to yarn damage due to cutting and laborious preparations of bobbins including searching of yarn ends for further processing requiring the use of both operator's hands is dispensed with.

Description

"Spool with layers of yarn"

The invention relates to a bobbin with wound layers of yarn and a central support sleeve.

For example, from DE-GM 17 19 313 is a conical cheese known, which is essentially characterized in that the wound yarn layer is surrounded by a protective cover.

In many cases today this protective cover consists of a so-called shrink film, which shrinks after the action of heat on the package and thereby the package holds and fixes the ends of the twine.

It has also become known that the ends of the yarn are used for transport purposes to devour a bobbin and wrap the bobbin in a plastic bag. Both The aforementioned methods are labor-intensive to carry out.

However, both of the aforementioned methods also have the disadvantage that the commissioning of the coil is time consuming, for example because of the plastic bag removed, searched for the thread end and then freed this thread end from the loop must be 5.

When using shrink films, the disadvantage arises that these Foil must be cut open with a special knife, causing damage the coil cannot always be avoided.

In addition, both are required to carry out this procedure Hands required, i.e. the operator performing this work must himself devote full attention to this work.

The invention is based on the disadvantages of the known Avoiding procedures and still creating a bobbin with layers of yarn, on which the yarn layers are securely held and a loosening of the yarn layer is avoided will.

This object on which the invention is based is achieved by a slightly adhesive properties sprayed on the outer peripheral surface of the coil having and washable film-like coating. Such a film-like coating can consist of textile auxiliaries or textile layers existing in the textile industry. Furthermore, it can be made from materials that are used today in hairsprays Use.

According to the invention, the coils are immediately after their completion, i.e. sprayed with this film-like coating after winding the yarn, whereby the individual layers of yarn are glued.

The invention further relates to a stand that is rotatable Carries coil carrier on which the coils themselves are rotatably arranged, the Stand is equipped with a spray device. Applying the film-like Coating can be done with the help of this auxiliary device, can in the same way but can be carried out with spray cans or spray guns.

Finally, the invention relates to a method of fixing of the thread layers in yarn bobbins, in particular Retrac bobbins, this method is characterized in that after winding the yarn, the outside of the bobbin with a liquid that has slightly sticky properties and is easily washable. The procedure according to the invention is that either only the coil jacket is sprayed or only the end faces of the coils are sprayed be or both.

It is also within the scope of the invention that only parts of the coil jacket and / or the front side are sprayed.

The drawings show an embodiment of the invention.

1 shows a retrac coil, the surface area being enlarged the bobbin can be seen and this drawing is intended to make it clear that the yarn layers be held in place only by a film-like coating, this filrike coating cannot be compared with the previously known film coatings, but only lightly and thinly, such as hairspray, applied to hair is, but has slightly adhesive properties and can be washed out.

FIG. 2 shows the auxiliary device that may be used according to the invention denotes, which consists of a stand 1 which rotatably supports a coil carrier 2, on which a coil 3 can be seen. The carrier 1 is designed to be movable and carries a tank 4 on its top, which can be seen in the drawing Nozzles 5 are now sprayed the top of the coil with the film-like coating can.
