Definitions

• One of the objects of the present invention is to greatly simplify the above described processes and apparatus.
• Another object of the present invention is to greatly increase the efficiency and rate of production of the abovementioned known processes and apparatus.
• a further object of the present invention is to render processes and apparatus of the above type almost fully automatic so as to decrease the required attention of attendants to a minimum.
• Yet another object of the present invention is to produce an apparatus capable of accomplishing all of the above objects and still being highly flexible so that the apparatus is capable of processing textiles of all types, whether they be natural or synthetic, or intended to produce yarns for weaving or knitting or yarns suitable for upholstery, tapestries, covers of all types, yarns for the cloth industry and felt industry, and yarns suitable for hand knitting.
• the present invention mainly consists of a method which comprises the steps of carding the raw textile material so as to produce rovings, directly and continuously feeding these rovings to a spinning machine, and spinning the rovings in the spinning machine.
• the present invention also mainly consists of an apparatus for processing textiles, this apparatus comprising a carding machine, a spinning machine, and guide means directly interconnecting the carding and spinning machines for continuously feeding rovings from the carding machine to the spinning machine.
• the spinning machine may have pairs of oppositely arranged spinning units which are located progressively nearer to each other in the direction away from the carding machine so as to provide a V-shaped arrangement having the wide end thereof located adjacent to the carding machine and having the narrow end thereof distant from the carding machine.
• Fig. l is a diagrammatic fragmentary, elevational view of one possible apparatus for carrying out the present invention.
• Fig. 2 is a plan view of and Fig. 3 is a fragmentary, diagrammatic, elevational view of one side of the spinning machine, taken transversely thereof.
• a carding machine on the left hand side thereof, a carding machine and, on the right hand side thereof, arspinning machine.
• the rovings l travel from the distributor 2 of the carding machine to the guide means located between the carding and spinning machine.
• This guide means may simplybe a plurality of horizontally mounted rollers arranged parallel to and in the same plane as the driven rollers 3 of the spinning machine. From the driven rollers 3 the rovings move continuously through the drawing mechanisms 4 of the spinning machine.
• These rollers 3 extend over the entire length of the spinning machine, and, as is apparent from Fig. 2, the rollers 3 are parallel to each other and of a progressively shorter length in the direction away from the carding machine.
• the threads pass through the reciprocated tubes 9 into the spinning bells S where they are wound in cross windings as a result of the centrifugal force which comes into play due to the speed of rotation and interior space of the spinning bells 8.
• These spinning bells 8 are each individually driven by a motor l5 which is operatively connected thereto.
• the spinning bells 8 are arranged along two rows which converge towards each other in the direction away from the carding machine.
• the spinning machine comprises pairs of oppositely arranged spinning units which are located progressively nearer to each other in the direction away from the carding machine so as to provide the V-shaped arrangement shown in Fig. 2.
• the rovings from the distributor 2 of the carding machine travel along straight lines on the top side of the spinning machine and are guided therefrom to the spinning bells 8.
• the rollers 3 each have a worm wheel xedly mounted thereon and driven by a worm mounted on the shaft '7 which is rotated.
• the worm is connected to all of the rollers 3 so that the latter all simultaneously rotate together at a predetermined speed which may be regulated by regulating the speed of rotation of shaft 7, in any known manner.
• a roving l travels downwardly over a roller 3 to a guide roller which directs the roving to the left hand side of the machine, as viewed in Fig.
• the tube 9 is reciprocated in a vertical direction by the chain drive mechanism 2S connected to the telescoped spindle 29 which is itself connected to the tube 9 by a vertically extending member mounted for reciprocating sliding movement in the guide 30.
• the spinning bell 8 is provided at its upper portion with a neck 12 which is mounted for rotation by any suitable bearing in the support member 13, the tube greciprocating Awithin the neck 12.
• the thread moving into the interior of the spinning bell S is ythrown towardthe wall thereof by the centrifugalforce producedtherein so that the reciprocating tube 9 feeding the thread into the bell 8 produces in' combination therewith a cross wound body of thread which presses against the interior Wall of the bell 8.
• the door member 11 is provided with a foot portion 14 in order to connect the spinning bell 8 with its individual driving motor 15.
• a coil spring 16 bears at one end thereof against the flange member 17 xed to the spindle of the motor and at the other end thereof against the iioor member 11-so ⁇ as to urge the latter into the spinning bell 8, and since the adjoining wells of bell S proper and floor portion 11 are conica-l, a wedg'eelikeacticn is produced to rotate member 8 along with the rotating door portion 11.
• the support 13 for thev motor 15 is connected to a slide member 2t) which has connected thereto the member 19 which is bifurcated at its leftv end, as viewed in Fig. 3, to engage a shoulder of member 14 so as to insure movement of the floor 11 toward and away from the ⁇ bell 8, upon.
• the apparatus is provided with a rail member 21 mounted for vertical sliding movement by means of the mechanism 2S which moves a chain guided over roller 26 and connected to the rail 2l.
• the spool supporting neck 22 On the pin 23, located on rail 21, is mounted the spool supporting neck 22, and the changing of a. full spool for an empty spool is simplilied by the raising of the'rail 21 so ⁇ that an attendant on platform 38, located on fopposite sides of the spinning machine, may conveniently change the spool.
• All movements of the spool changing mechanism may be driven from a special motor which becomes energized as soon as the spinning proper is terminated.
• the shaft 34 is automatically rotated so as to rotate the gear 35 which meshes with the rack 36 to move the support member 13 to the left, as viewed in Fig. 3, along the guide rail 37 so as to locate the spinning bell in the -dotted line position over the spool member 22, as shown in Fig. 3, the telescoped spindle 29 being thereby extended.
• the floor 11 is 4lowered from the bell 8, by the structure described above.
• This lowering of member 27 causes the Wound thread located Within the bell 8 and clinging to the walls thereof to be separated therefrom and fall onto .
• FIG. 3 The above described structure, shown in Fig. 3, is only intended to clarify the structure shown in Figs. l and 2, the ⁇ present invention being directed to the latter rather than tothe details shown in Fig. 3. However, the latter figure is believed to demonstrate that the present 1nvention is capable of being carried .out by a single row of spinning units located along one side of a spinning machine, as well as a double row arranged in a V-shape, as shown in Fig. 2.
• the starting and stopping of the entire apparatus may be controlled from a single switch, and the speed of thread movement together with the delivery rate can be correlated with the speed at which the spinning bells are driven by any suitable electrical apparatus.
• the speed of rollers 3 may be regulated gradually through a fairly large ⁇ range of speeds so'tha't the apparatus may be suited to any particular materials, while maintaining the rovings fed from the distributor 2 substantially untensioned.
