The invention relates to a double cylinder circular knitting machine with a pattern cylinder arranged inside the upper needle cylinder, in whose slots selectable by a pattern device Transfer thread guides are used.

It is already known to produce plush goods by working with two or more threads, whereby the individual wales are connected to a knitted fabric by so-called sinker stitches are. The plush thread must form a longer loop on these sinker loops than the basic thread. For this purpose, ground and plush threads must be passed separately to the place of work so that the base thread under the hook and the plush thread over the hook of the required plush sinker runs along.

In order to be able to work according to this known method, it is necessary to have a specially built one Machines to use. Understandably, this had the disadvantage that the machine park was undesirable Wise must be enlarged and these machines are only useful when knitting plush goods shall be.

It is also already known to make terry stitches on a double cylinder circular knitting machine produce that the components suitable for the terry manufacture in the required position to be brought.

The object of the present invention is to provide a double-cylinder circular knitting machine with a fold-over plating device to train so that stocking sections, such as heel, foot and toe, are plush can be produced.

According to the invention, this object is achieved in that the slots of the sample cylinder are optional are occupied with plush sinkers, which are assigned a plush lever that can be controlled according to the pattern.

The invention has the great advantage that on the same machine optionally, without Conversion, clad goods, plush goods or plush goods combined with cladding can be produced can. All that is required is the installation of the elements for the plush production, as the Pattern device for plating is already in place.

An embodiment of the invention is in the following description and in the drawing shown. It shows

F i g. 1 shows an upper needle cylinder of a circular knitting machine equipped according to the invention in a side view, partly in section,

F i g. 2 is a plan view in section AB of FIG. 1,

Double cylinder circular knitting machine

Applicant:

Josef Sommer stocking factory,

Furtwangen (Black Forest), Allmendstr. 32

Named as inventor:

Josef Sommer, Furtwangen (Black and White)

F i g. 3 a plush board,

F i g. 4 a thread guide and

F i g. 5 a combined plush board with thread guide.

The sample cylinder 12 is slid onto the fixedly mounted guide cylinder 14 so that it is held and guided by the guide cylinder 14. In the sample cylinder 12, vertical slots are milled into which the plush sinkers 7 are guided. The plush board 7 is equipped with the plush hook at its lower end. In the slots of the sample cylinder 12, which do not lead any plush sinkers 7 or sample sinkers, filler plates 9 are used, which serve to avoid bending of the cylinder webs.
The actual loop-forming element is the needle 11, which can work as a right needle in the lower needle cylinder and as a left needle in the upper needle cylinder. In the drawing, the needle is shown as a right-hand needle, since plush loops can only be formed with right-hand needles or knitted stitches.

The needle cylinder is designated by 15, which, like the pattern cylinder 12, has milled slots is provided, the number of slots in the needle cylinder corresponding to the number of slots in the pattern cylinder. Both cylinders are firmly connected so that the needle cylinder can rotate the pattern cylinder participate.

The sample drum 10 in conjunction with the sample rocker serves to actuate the thread guides 8 13th

To operate the plush sinkers 7, the plush lever 1 in conjunction with the run-up parts 6 is used left and 5 right. By means of the control drum known per se, the plush lever 1 is actuated via pressure bolts 2 pressed or lifted off the transfer lever 4 on the sample cylinder 12.

Through the run-up part 6, the upper part of the plush sinker 7 is pressed outwards, whereby this

is brought to rest. This run-up part is only used in the pendulum walk, e.g. during production from the heel and toe of a stocking. The ramp part 5 has the same task as the ramp part 6, only with the difference that it is used in concentricity and pendulum motion. In order to explain the operation of the device according to the invention, it is useful to follow the path the needle 11 and the plush sinker 7 to follow, starting at the highest point of the Auflauf- ίο part 6 left. The lower and upper needle cylinders make a counter-clockwise rotation in the same direction. The needle 11 runs in the lower needle cylinder and makes the indicated cylinder movement another vertically rising movement. This movement is caused by a (not in the drawing caused) run-up part in the lower needle cylinder. Needle 11 reaches its highest point when the plush lever 1 touches the pattern cylinder 12 in this way. At this point the foot is already the Plush board 7 has been pushed all the way back into the cylinder slot by the plush lever 1, so that the Plush hook protrudes from the cylinder slot. Here, the position is reached as shown in FIG. 1 shows. In this position to each other, needle 11 and plush sinker 7 move until the upper shaft of the Plush plate 7 touches the casserole part 5 on the right. During this time the basic and the Brought plush thread to the needle. The basic thread must be below and the plush thread above Hooks of the plush sinkers 7 are. From the run-up part 5, the upper end of the plush sinker 7 is now outwards and thus the Plush hook led inwards. This pulls the thread handle off the plush hook. Simultaneously When the plush handle is stripped off, the needle 11 moves upwards and is in the rest position. During the remaining half of the cylinder revolution, there is no stitch or loop forming Work done by the needle 11 "or the plush sinker 7. If the heel and toe of a stocking are to be made of plush, then all three cylinders are made given a pendulum movement, namely 360 ° clockwise and 360 ° counterclockwise. During this operation, half of all the needles are put out of action, so that only the needles work, to which, as in F i g. 2, a plush board faces. The operation of the plush board 7 is the same as in the case of the round trip described above. However When turning clockwise, the plush board 7 is turned back in from the ramp part 6 on the left Brought to the starting position. By lifting and pushing in the plush lever 1, which is via pressure bolts 2 and transmission lever 4 is switched by the control drum, can be at any Place a commodity, e.g. B. a stocking, the plush device according to the invention in or outside Activity to be brought. In the F i g. 3, 4 and 5 are each a plush board 7, a folding thread guide 8 and a combined plush sinker with folding thread guide 17 for use shown in the device according to the invention. Claim: Double cylinder circular knitting machine with one arranged inside the upper needle cylinder Pattern cylinder, in its slots of a pattern device selectable thread guides are used, characterized that the slots of the sample cylinder (12) optionally occupied with plush sinkers (7) are assigned to a plush lever (1) that can be controlled according to the pattern.
