Abstract: <PICT:0353197/IV/1> <PICT:0353197/IV/2> An artificial silk spinning machine comprises a spinning device and a wet treatment device arranged on the machine frame, and means whereby the winding bobbins, the total number of which is a multiple of that of the spinning nozzles, are operatively associated alternately with each of said devices.  The groups of bobbins may be arranged on a common support which may be turned so that there is always one bobbin of each group in position to be wound with artificial silk whereas the other bobbins are in position for treatment with liquids or for being changed.  The common spindle is provided with bobbin carriers provided with sealing packings which seal one of the ends of the inserted bobbins.  Liquid supply pipes with spraying nozzles are provided on the machine.  During the liquid treatment the bobbins which are hollow may rotate and the liquid which is sprayed in the open ends of the bobbins is caused by centrifugal force to pass transversely through the wound layers of thread.  The bobbins which are being wound may be subjected in a similar manner to a preliminary liquid treatment.  Alternatively, the bobbins may be stationary during the liquid treatment and the liquid supply pipe is adapted to form a liquid-tight joint with the interior of the bobbins.  In this case the liquid is forced through the thread layers under pressure. As shown in Figs. 1 and 2, the bobbin driving shaft 22 has double bevel gear wheels 6, 61 and is arranged inside a tube 5 which moves as a tiltable bobbin carrier. The bobbins are arranged in two opposed rows, staggered in relation to one another.  The bobbin holders 8 are provided with rubber rings 9 upon which the bobbins 1, 11 are tightly pushed.  The bobbins consist of hollow cylinders perforated on their circumferential surface.  The laying of the thread is effected by the oscillating thread guide 2.  The fully wound bobbins 11 are brought from the winding position to the rest position by tilting the bobbin carrier 5 by means of the cam 18.  At the same time the opposite bobbins 1 are brought into winding position and the bevel gears 6 are brought into mesh with the bevel gear wheels 7.  The pipe 13 is displaced until its supporting arms 14 strike stops 24 on the rod 15, and is then tilted downwards until the individual connecting pieces fit tightly on the open ends of the bobbins.  It is then connected preferably by flexible tubing with the liquid supply pipe.  The liquids are thus forced from the interior of the bobbins through the thread layers.  At the completion of the treatment, the pipe 13 is swung up, the treated bobbins are replaced by empty ones, and the bobbin carrier is turned so as to bring the wound bobbins 1 into position for treatment.  In order to bring the connecting pieces into register with the position of bobbins 1, the pipe 13 is displaced until the arms 14 strike the stops 23.  In a modification, the opposed rows of bobbins are not staggered in relation to one another, and they are caused to rotate during the treatment with liquid which is sprayed into the interior of the bobbins and passes through the thread layers by centrifugal force. In another construction two driving shafts which alternately rotate and stop are geared to alternate groups of bobbins.  While one group is being wound with artificial silk, the other group is stationary and is being treated with liquids.  The liquid distributing pipes are mounted on rods on which they may be axially displaced so as to be brought alternately into contact with each group of bobbins.
