Device for removing thread ends

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing cut thread ends on a two-cylinder circular knitting machine provided with a shearing and holding device for inoperative thread ends consisting of a body. are also nozzles connected to a source of compressed air whose mouths are directed to the working ends of cutting and holding foils.

BACKGROUND OF THE INVENTION 15

It is known that two cylindrical knitting machines for the production of sock goods have nozzles in the body of the cutting and holding device connected to a source of compressed air whose mouths are directed to the working ends of the cutting and holding blades. This arrangement has the task of blowing from the cutting and holding area of the threads their cut ends, which then contaminate the machine

2u in the area of the knitting head, The knitting head must then be cleaned from time to time to avoid clogging and thus to malfunction of the machine. The task of the finding is to eliminate this disadvantage.

SUMMARY OF THE INVENTION

The device according to the invention is characterized in that a nozzle mouth connected to the suction outlet of the machine fan is arranged above the working ends of the cutting and holding foils.

Further, it is preferred that the nozzle is arranged in a horizontal position and its mouth is obliquely cut and this extends over the cutting and retaining blades.

Summary of the drawings

The device according to the invention is shown in the accompanying drawings, in which: FIG.

Example (s) for carrying out the invention

The known small diameter two-cylinder circular knitting machine for the production of sock goods is provided with a shearing and holding device. This device comprises a body U in which the cutting and holding blades 2 are slidably mounted. Opposite the working ends of the cutting and holding blades 2 there are holding fingers 3 abutting thereon. Furthermore, in the body 1 of the cutting and holding arrangement, the nozzles 4 are centrally connected via a conduit 41 to a source of compressed air, their mouths facing the working ends of the cutting and holding foils 2. The cutting and holding foils 2 are controlled by levers 21, sticks 22 abutting the pneumatic pistons. 23 and springs 24, as known from Czechoslovak. No. 3666.

Mounted to the body 5 of the pneumatic pistons 23 is a holder 6 in which the nozzle 7 is attached and connected to the suction outlet of the machine fan. Between the nozzle 7 and the fan there is a shredding basket. The mouth 7 of the nozzle 7, which is arranged in a horizontal position, is cut obliquely downwards and is positioned above the working ends of the cutting and holding blades 2 so that they extend in the horizontal direction.

The operation of the device described above is as follows. During operation of the machine, the fan is constantly switched on so that the nozzle 7 sucks air from the space above the working ends of the cutting and holding foils according to the program. The cutting and holding planks 2 then operate according to the machine program and, depending on this, also the compressed air is released into the nozzles 4. This compressed air then carries the cut ends of the inoperative threads, which by cutting on the nozzle 7 strikes its inner surface in the region. they are then sucked through the nozzle 7 into the shredding basket.
