Description

The invention relates to a bobbin stand for circular knitting machines.

In the known designs, the bobbin stand is arranged such that the bobbins are essentially on the stand are stored vertically. This has the disadvantage, especially in multi-system machines and when using large-diameter reels, that because of the large number to be accommodated Coils the bobbin rack has too large a diameter and the bobbins in two or several concentric circles must be arranged. The main disadvantages here are poor accessibility to the inner coils, excessive height of the machine and the amount of dust of the coil end faces. These difficulties are felt to a greater extent in cases in which two or three bobbins are required for a knitting point, as z. B. in manufacture occurs from patterned goods or from plush goods. The one on the end faces of the coils Dust that settles out is carried away by the unwinding yarn. It then causes it to tear off of the thread in the knot catcher or even in the needles that graze damaged, or finally in the Goods whose quality is impaired. In addition, smooth materials must be used when processing (Silk, polyamide) should be provided under the coils to prevent the flag from slipping.

For the same reasons, the tree-shaped or radial coil stands, in which the coils stand up, are used are arranged on arms or arches and from which the threads are led steeply upwards, Not suitable for multi-system machines and for the use of large-diameter spools.

Also the well-known bobbin stands used for flat knitting machines with a significant supply of yarn for one thread guide each, e.g. B. several bobbins for a thread guide, in which the yarns of all Coils of a row are linked one behind the other and the coils are arranged obliquely to one another so that they are directed towards a common point so that all the threads unwind in the direction of the axis, do not solve the problem which is the subject of the invention as it is not possible in such a way is, especially for multi-system machines and when using coils with a large diameter, to create a bobbin rack that can be accommodated in a small space and operability the circular knitting machine is not affected.

According to the invention, however, this is achieved in that on circular, concentric to the needle cylinder, frames arranged one above the other, the bobbin stands for circular knitting machines

Push-on pins for the bobbins are fastened essentially horizontally, of which the yarn is in the Coil circle is withdrawn into it in a substantially horizontal direction.

An exemplary embodiment is shown in the drawing.

The bobbin stand has circular, concentric to the needle cylinder, arranged one above the other Frame 1, on which pins 2 for the coils 3 are fastened essentially horizontally, of which the yarn 5 is drawn off into the bobbin circle in a substantially horizontal direction.

If the number of coils makes it necessary, place them in three circles one above the other are to be arranged on the circular frame 1 detachably attached arms 4 with horizontal push-on pins attached for additional coils.
