れる。BACKGROUND OF THE INVENTION Clamping and cutting devices are known for all types of knitting machines. When switching to a yarn of another color or nature, cutting and tightening of the knitting yarn is required. In circular knitting machines,
The yarn exchange is performed at all knitting speeds. The clamping and cutting devices used therein generally have finger-like elements, which distribute the thread to the knitting needles or fasten from these knitting needles. From the fastening position the thread can be cut by blades or scissors and held by different types of fastening devices. In a flat bar circular knitting machine, each thread must be cut on leaving the needle bed and re-supplied to the needle on entering another needle bed. The clamping and cutting devices for these knitting machines therefore have a thread-clamping element that follows the yarn path, the thread-clamping element keeping the thread in a tightened state before the thread is cut. The tightening element allows the yarn to be held below the exit opening of the yarn path, so that the first needle of the next needle bed can catch and knit the yarn. After the yarn is tied to the knit with a new needle bed, the yarn end that is still tightened is released.

In addition, for annular colored stripe knits, only short yarn ends at the beginning and end of the color gamut are present, instead of a yarn loop extending along the side edges of the knit to the next stripe of the same color, to clean the knit edges later. This is advantageous.

Only when the yarn has already been fed by the yarn path to a plurality of needles at the knitting edge, the yarn is cut. Thereby no clamping device is required. However, depending on the height of the knitted area formed by the knitting yarns, yarn ends of very different lengths occur at the knitting edges, which makes later off-the-shelf production difficult.

4 shows a cutting device. In this case, two clamping devices are provided for one cutting device, so that the yarn of the cylindrical circular finished knit can also be processed. One clamping point can hold the thread that is cut after the sleeve is formed, and the other clamping point can hold the thread that is cut after the entire knitted piece is completed. However, two fastening points on one side of the needle bed, or two fastening points on each side of the needle bed, individually separate the yarns as required for a suitable annular colored knit with more than four colors. I cannot accept it. Furthermore, this number of fastening points is not sufficient for a knitted piece formed at the so-called flank opening. However, when a plurality of such tightening-cutting devices are provided side by side, the length of the yarn end for each tightening portion becomes large, and a stroke of the yarn end beyond the side knitted fabric end also occurs.

The problem is solved by being provided on a perpendicular surface. With this device, the yarn is cut at all tightening and cutting points on a plane perpendicular to the needle bed longitudinal direction,
Approximately the same length of yarn end results. In addition, this arrangement of the cutting and tightening points requires little additional installation space in the machine direction.

る。Another great advantage is that the yarn path has to move only very slightly over the end of the knitted fabric in order to be able to supply the yarn to the clamping and cutting device. Only one thread distribution mechanism is provided in the form of an element with a pivotally supported and hook-shaped element, and the tightening and cutting point is provided on an arc around the center of rotation of the thread distribution mechanism. Good to be. Providing only one yarn distribution mechanism not only reduces the cost but also allows easy control. At this time, the yarn distribution mechanism can receive the yarn at the upper swinging position as much as possible, and can transfer the yarn to the tightening and cutting position at the swinging position below this position. A relatively large height difference is possible.
This has the advantage that the thread which is moved away from the clamping point by the thread path is also reliably inserted into a needle which is greater than the edge of the needle bed with respect to the clamping part.

In that case, the speed of the yarn distribution mechanism at the critical stage during yarn reception and yarn transfer is optimally controlled. The drive shall be designed so that the yarn is captured, tightened and cut fast so that the carriage moving the associated yarn path can move at a knitting speed which is not reduced beyond the yarn tightening and cutting device. Can be. The multifeed carriage can also move beyond the tightening and cutting device at the maximum knitting speed, whereby the yarns of all the yarn feeders are tightened and cut. By means of a separate drive of the clamping and cutting device, it is also possible to release the thread to be clamped again irrespective of the position of the carriage.

A clamping surface cooperates with the surface of the clamping roller. Such a clamping and cutting needle thus fulfills several functions. The clamping and cutting needle accepts a knitting yarn in its yarn space from at least one yarn distribution mechanism, clamps the yarn on its clamping surface and cuts the yarn on a cutting surface cooperating with the cutting blade. During the cutting process, there is no loose thread portion that can accumulate in the tightening-cut range.

It can be securely tightened regardless of its thickness and surface properties. Therefore, a plurality of knitting yarns having different thicknesses and structures can be tightened. In this case, the tightening, cutting and releasing can be performed at the respective tightening and cutting points of the yarns of the other yarn paths. However, it is also possible to cut a plurality of yarns by tightening them at one tightening and cutting point. The swingingly supported cutting blade can be pressed by a spring force against the cutting surface of the clamping and cutting needle without play. The spring, which presses the cutting blade against the cutting surface of the clamping and cutting needle, can simultaneously press the entire clamping and cutting needle against the clamping roller, whereby a particularly simple mechanical structure of the clamping and cutting point is obtained.

い。Furthermore, it is advantageous if, after the tightening and cutting of the yarn, the tightening and cutting needle releases the yarn end by means of its end face when leaving the tightening section. As a result, no additional device is required for releasing the thread ends. The individual clamping and cutting needles are driven individually but preferably by a common drive. In this case, the drive is provided with a mechanism for selecting the clamping and cutting needles at different clamping and cutting points, which furthermore preferably prevents collisions between the clamping and cutting needles.
