This invention relates to an arrangement for leading ofi the ends of threads at breakages by suction action, particularly for Spinning ma chines.
Such arrangements are hitherto known in many types but have the defects of necessitating costly plants or bein disadvantageous in the function of the plant.
A special disadvantage of the known devices is that on the two sides of the spinning machine right hand andleft hand suction pipes that is to say different suction pipes-are necessary so that their manufacture is complicated, because in such a way during the manufacture the individual parts of the pipe must be always held separately and yet mistakes often happen. In addition the control and the packing of the suction pipes is also difiicult. Usually in the spinning factory spare suction pipes are in stock, and
in consequence of the known construction of these pipes, it is necessary to hold in stock both right hand and left hand suction pipes.
The arrangement of the suction pipes according to the invention makes possible to work with only one type of suction pipe, that is to say for the whole spinning machine only right or only left hand suction pipes may be used so that the said difficulties are eliminated.
In the drawing:
Fig. 1 is a schematic cross section of a double sided spinning machine embodying the features of the present invention.
Fig. 2 illustrates the arrangement of the suction pipes as shown in Fig. 1.
The machine has a frame I, drafting rolls 2, creel 3, roving bobbins 4 and the other parts for the arrangement, as well as the conduit or channel 5 with the profile of a half barrel shape, and the suction pipes connected to the channel.
The roving goes from the roving spoolsor bobbins through the draitingrolls 2 and the thread from it pass across the L-shape suction pipes 8 which are supplied with holes according the spacing of the spindles. Upon rupture of the threads the ends leaving the drafting rolls are continually withdrawn with the stream of air entering the suction holes in the suction pipe guides the thread to the channel, on the end of which there is a usual exhauster producing the necessary vacuum, and a filter case for collecting the thread material for re-use.
In accordance with the invention, as shown in Fig. 2, the pipes 6 are arranged on the channel 5 along the spinning machine. 10 is the beginning and II the end of the channel. Fig. 3 shows the pipes 6 at both sides of the spinning machine in left-arrangement but if necessary they may be made on both sides in right-arrangement too. The suction-holes I! are spaced according to the spacing of the spindles.
I claim:
In a device for collecting the ends of broken threads in a spinning machine, a suction conduit, anda series of L-shape suction pipes detachably connected with the conduit in communication with the interior of said conduit, said pipes located in the path of the traveling threads in such way that they are adapted to draw the broken thread ends, and arranged at each side of the conduit so that the pipes project in one longitudinal direction at one side of the conduit and in the opposite direction at the other side thereof, the pipes at one side of the conduit being interchangeable with the pipes at the other side of the conduit.
HANS BARTSCHI.
