Knitting and warp knitting machine

The invention relates to a knitting machine, each with needles guided in a needle bed.

In order to use Sbaub, Flusen and the like in knitting machines bdi the production of the yarn loops arise ^ if possible In circular knitting machines, blowing devices are already installed inside the machine behind the needle bed provided that blow through the needle bed to the outside onto the loop formed and so the resulting there Remove lint from the goods. With such facilities

However, not only are lint and dust removed, but the oil in the needle bed is also blown to the outside, whereby the goods are significantly soiled. In addition, ♦ is because the opening of the blower is at least around the Length of the needle bed is away from the vare, a correspondingly high fan power is required ..

The invention is based on the object of creating a device in which the disadvantages of the previously known devices are eliminated and dust, pluses and the like can be reliably removed without impairing the goods and the surrounding air. [

The essence of the invention is that in the area in front of or behind the needle bed on the yarn feed side at least a needle, the opening of at least one suction member is provided. With a device equipped in this way the aforementioned disadvantages of the known devices are eliminated in one fell swoop. Soiling of the goods oil is no longer possible. Because the opening of the suction organ can be brought up to the immediate vicinity of the loop to be formed, can be with large Efficiency to keep the knitting or knitting machine clean

Knitting machines, such as the presence of the also Blowing devices that have been in use for a long time proves the need for the most effective possible dust and lint removal has always been present, so far no one has dared to address this problem by suction directly in the To solve the area of the needle bed.

The solution according to the invention is "particularly suitable and..." advantageous for dog knitting machines. In principle, however, it is just as good for other knitting machines applicable. In such cases, the invention provides in particular that with a large number of suction elements, the fan power to keep small, these individual, each arranged in front of a needle bed suction members briefly one after the other can be switched on or connected to the induced draft. The respective activation of the individual suction organs can be done in one be controlled in a very specific rhythm, in a very specific cycle, roughly synchronized with the movement of a shuttle moving past the needle beds. This can be done in the suction organs or in their supply lines arranged valves or other controllable closure elements can be provided, which by any suitable, control mechanism familiar to the person skilled in the art can be actuated.

In a besor leren embodiment of the invention, the suction member is designed as a nozzle to the one with the suction

side of a blower connected suction line connected. The formation as a nozzle enables a directional effect and concentration in a particularly simple manner of the induced draft "on a certain area, so that the fan power for the generation of this induced draft can be kept low. The supply of this induced draft via lines can vary in terms of space and structure Conditions must be adapted in the most expedient manner. In most cases, the feeder will be the Lines from the outside are the cheapest. In principle, however, the line routing can also be used if this is appropriate. should prove to be more moderate, should be done from other directions, for example from the machine.

In a further development of the invention it is provided that the suction member is releasably attached in the area of the needle bed. This can be done in particular in that the ψ nozzle is mounted in an adjustable holder attached to a lock. This possibility of removing the suction organ means that you have access to the individual lock at any time. . To carry out any work necessary there. This possibility of access is further improved if, according to the invention, a suction line connected to the nozzle is designed to be flexible. Furthermore , it is recommended within the scope of the invention to have this suction line an.eine with

the collecting suction line connected to the blower suction side to connect, which runs above or below the level of the needle bed .. This measure also contributes to improve access to the needle bed and lock. In the case of waistband knitting machines, this is the collecting line expediently designed as a correspondingly curved downline.

The solution according to the invention can in principle also be used in such circular knitting machines in which the individual needle beds and locks on a rotating plate Are arranged., Here, for example, the individual suction organs can be fixed at a distance corresponding to that two needle beds can be arranged around the plate. In a particular embodiment of the invention, however, is also provided that with such frequently occurring arrangements of needle bed and lock on a rotating plate Suction element made up of an inner part rotating with the plate, arranged in front of or behind the needle bed, and a stationary part stored outer part, the inner and outer part briefly during the rotation of the plate cover while creating a suction effect.

The invention is shown in the drawing by way of example and 'schematically shown. Show it:

The section shown in Fig. 1 through a knitting and Knitting machine represents in the case of a circular knitting and warp knitting machine a radial section, in the other case a cross section. Each on a lock 10 below a needle bed

a holder 8 is attached, which has a nozzle 6 in a clamp 7 holds. With holder 8 and clamp 7, the position of the nozzle 6 is like this fixed that its opening is directed to the area immediately in front of the needle bed 11 where the loop formation takes place. Its job is to remove the fibers, fluff and balls of dust that arise during the work process. This is on this nozzle 6 is connected to a preferably flexible suction line 5, which is fed to a pipe 1 and connected to this by means of a sleeve. This pipe 1, which has a The filter, not shown, is connected to the suction side of a blower is secured by elastic sleeves with holders 2 ™ to a web 3 or directly to the knitting machine, namely higher or lower than the horizontal of the needle bed 11 attached. The thread eyelet 9 can be placed in the holder 2 if necessary.

Needle bed 11 can be attached. In addition, an actuating member of a valve or other closure member provided in the nozzle 6 is shown schematically at 16,

in order to indicate that within the scope of the invention, of course • only a temporary activation and actuation of the suction elements can easily be provided. Such controllable closure members can of course also at any other suitable location, for example be provided in the cable run 5 ».

2 shows a radial section through a circular knitting machine in which the individual locks 10 and needle beds 11 are arranged on a rotating plate 13. In this particular embodiment, the suction element can be divided into two parts 6a and 6b, the inner part 6a being fastened to the lock 10 located on the rotating plate 13 by means of a clamp 7a, while the outer part 6b is fastened by means of a clamp 7b is connected, for example, via a bracket 15 to the stationary part 14 of the χ machine. Both parts 6a and 6b are fixed in their holders in such a way that during the rotation of the plate 13 the inner part 6a, the mouth of which is directed directly at the needle bed 11, briefly with its outwardly directed opening corresponds to the corresponding opening of the outer, stationary part 6 b is opposite, so that at this moment, when both parts coincide with their openings facing each other, the suction in the area of the needle bed 11 becomes effective.

It is clear that within the framework of the invention, the arrangement
