' SPINNING MACHINE Filed March 15, 1928 Patented Jan. 14, 19 30 WILLY GROSS, OF BOTTWEIL-ON -'1HE-NECKAR, GERMANY srmme mcnmn Application filed larch 18, 1928, serial No. 281,375, and in Germany Apr-11 3, 1926.
The present invention relates to a spinning machine which has a considerably increased output in comparison with the' spinning machines hitherto known, inasmuch as the speed of the spinning process is considerably increased.
The low output of the spinning machines hitherto known is to be ascribed to the manner in which the rotation necessary for holding the fibres together is imparted to the yarn. Heretofore this has been done by causing either the finished yarn or the rov ing to rotate, which involved setting lar e quantities of yarn in rotation or where t e yarn is worked in small quantities frequent stoppages of the machine for the purpose of removing the finished yarn and inserting fresh yarn was necessary.
According to the present invention these disadvantages are avoided by sup lying the fibrous material to the twisting evice that is to say the spinning device m a loosened state, so that the yarn is only formed at the oint where it is twisted or rotated and so ormed by the accumulation of the separate fibres that is the fibres reaching the spinning device in a loosened state. These are carried along by the rapidly rotating. spinning device, and therefore caused to rotate rapidly and the yarn or roving is then formed by the fibres which have accumulated in the spinning device being twisted together durin the continuous drawing down which tal es place and so spun into thread.
A number of constructional forms of the subject matter of the present invention are more fully illustrated in the drawing.
Figure 1 shows diagrammatically in vertical axial section one constructional form and Figure 2 shows another construction of a part of the centrifuge in axial section.
.Figure 3 shows on a larger scale and 1n vertical section the shut ofi apparatus.
Figures 4 and 5 are an enlarged axial section and plan of a second construction of an apparatus for positively carrying the fibres through the spinning device.
In the machine according vto the resent invention there is attached to the elivery deposited owing to the action of centrifugal 6 force and their loose state as a fleece on the widest part of the centrifuge d and are carried along thereby that is to say are likewise caused to rotate rapidly. The fibres drawn out continuously and uniformly at the boto5 tom of the centrifuge are twisted together ,into yarn at the lower end by their adhesion.
For this purpose they are run between clamping rollers e and a continuous thread is produced, which is passed on directly to 7 i any desired vtype of winding or reeling device f. I
According to this invention the fibrous material in the centrifuge is brought into positive connection therewith so as to ensure its being carried along thereby that is to say to ensure that it shall make the same high number of revolutions as the centrifuge d whereby the machine is rendered capable of a great output or capacity. For this purpose and according to the construction shown in Figure 1 a all g is .inserted loosely in the centrifuge d and bears owing to centrifugal force against the inner wall of the centrifu e d at the widest part thereof or is presse against the imier wall thereof so that it'is posltively carried along thereby.
According to this invention a second factor of safety is therefore provided. This consists in the fact thatthe thread does not have theentire rotation imparted to it both in the centrifuge d and on its emergence therefrom but only a portion of the rotation at first. A roving is therefore roduced and only so much rotation imparte thereto as is required for the fibres to hold together and to release the fleece from the wall of the centrifugal.
For this purpose the centrifugal is made in two parts, the lower one rotatingmore passage 0 into a nozzle-shaped 5 the diflerence 'between the rotations of the two arts d and h.
en treating refractory material that is to say material which only takes the rotation with difiiculty, the fact that the centrifuge is made in two parts may also at first roduce over-twisting of the yarn by the ower portion 7:. being rotated in the opposite direction to the upper part (1. In consequence hereof the two rotary'movements become added together and the yarn is at first overtwisted between the up er and lower portions of the centrifuge. 1s overtwistmg is however equalized when the yarn emerges from the'lower part h of the cen'trlfu e and before it passes to the draw off or do%.n rollers e the overtwist passing over into t e normal twist. In order to secure the effect aimed at the thread running through the lower portion h of the centrifuge must' be offered such an amount of resistance therein that it does not rotate here of itself but lies still or rotates with the lower portion of the centrifuge. This may be effected by any desired means. In the constructional example accordin to Figure 1' the passage k for the threa is provided for this purpose with a lateral outlet opening 1 running obliquely to the axis of rotation, but other means such. for example as springs 71 may be used in the portion 12., see Figure 2. In the first case thethread wraps itself slightly round the point of the lower part h and is therefore prevented from rotating of itself.
In Fi res 4 and 5 is shown an example of anotfie r construction of the apparatus, which ensures the fibres being carried through the centrifuge d. In this case two 'feed rollers m are provided, which are rotated positively and carrythe bundle of fibre between them and along with them. The fibres are consequently positively disconnected from the wall and delivered to the opening of the nozzle. This enables the material to be slightly drawn if the speed of the dofiing be made greater than the speed of rotation of the feed rollers m in the centrifuge d.
The .feed rollersm are 'rotated continuously by. a worm gearing during their rotation about the axis of rotation ofthe centrifuge. For this pu ose the latter rotates in a stationary nut rlng' n and the roll-- ers m have a corresponding screw thread 0 on their peripheries.
The operation of spinning is started by drawing a thread from below by the aid of a needle through the centrifuge d and it up to about its upper edge. When the centrifuge d and 71. rotates the fibres they hang 1,14a,eo1
themselves on to the loose end of the thread and twist themselves together.
Finall means are also provided for me chamcal y stopping the supply of fibres to the centrifuge d and h at once should the thread break: For this purpose a cut off device of any kind, for example a rotary valve 12 is placed in or in front oftheforce pipe of the suction device 6 which inthe constructional example, is made in the form of a fan or blower, and according to its position controls either the force pipe 0 or alternately opens and closes a waste or exhaust pipe 0 which opens into a collecting receptacle (not shown). The valve I p is controlled electrically, a contact 1' closing automaticall when a thread breaks. The closing of t e contact excites an electromagnet s the armature t of which in its turn reverses the valve. This valve p can however be also controlled in other ways.
Instead of the fan or blower 6 shown the drawing in of the fibres might also be otherwise efl'ected as for example b a compressed air blower or the fibres may e drawn from a drawing frame or other apparatus for loosening the fibres; The centrifuge itself may also be so constructed that it has a suctional action and a separate suction device thus dispensed with. Instead of using air the suppl fibres to the centrifuge may be effected b another fluid such as steam, gases, etc. f an adhesive be also blown in with the fibres the yarn can be simultaneousl sized. 1When blowing in any other desire same time.
