A yarn feeding funnel for a textile spinning machine having an upper shaft portion and a body portion. A yarn inlet opening in the upper shaft portion is radially offset from the axis of rotation of the yarn feeding funnel and facilitates the formation of a yarn balloon of controlled extent between the yarn inlet opening and a yarn guiding eye which is coaxial with the funnel rotation axis. A plurality of alternative yarn inlet openings, each at a predetermined, different radial spacing from the funnel rotation axis, may be provided to vary the characteristics, such as the diameter, of the yarn balloon formed between the yarn inlet opening and the yarn guiding eye.

In the process and apparatus for loading a ring spinning machine with roving-supply bobbins at least two bobbins rows extending longitudinally on each side of the spinning machine supply roving to the work stations and a auxiliary bobbin row which can travel in with full bobbons and out with empty bobbins are provided. According to our invention an exchange process is provided comprising replacing the roving of the bobbins in one of the bobbins rows supplying the roving which is being consumed by the roving of the auxiliary bobbin row which has been brought in with full bobbins. Thus the auxiliary bobbin row becomes one of the bobbin rows dispensing the roving while the bobbin row being replaced now becomes the auxiliary bobbin row with empty bobbins and is taken away. A new auxiliary bobbin row with full bobbins is then brought in. The exchange process is repeated for each of the bobbin rows as the roving is exhausted. A simple space saving apparatus for performing this process is described.

Process and apparatus for loading a spinning machine with roving-supply

Bobbins wound with rovings from a preparatory stage are loaded onto a carriage which receives them on an orthogonal array of horizontal pegs and transports them to a holding station for transfer, one column at a time, to a service unit moving continuously or intermittently past a multiplicity of working positions of a ring spinning machine whose spindles draw the roving from bobbins on a supply rack. The service unit, whose primary function may be that of a yarn-tying device or a traveling air blower, has a vertical conveyor with stems alignable with the pegs of the carriage in the holding station for picking up the bobbins to be transferred and delivering them, individually, to storage areas at or near the supply rack where fresh bobbins are needed as determined by a sensor aboard that unit. The storage areas may have overhead grippers onto which a bobbin is pushed from an erected stem at the upper vertex of the vertical conveyor.

A filament drawing apparatus has a support, at least two pairs of rollers spaced apart on the support in a travel direction so that a filament to be drawn passes in the direction between the rollers of both pairs, and a drive having at least two output shafts and including a transmission for rotating the shafts at different speeds. One of the shafts is connected to one of the roller pairs and the other roller pair is displaceable on the support in the travel direction relative to the one roller pair. An input gear is mounted on the other output shaft and an output gear is mounted on one of the rollers of the other roller pair and is displaceable therewith in the direction. An input link has one end pivoted at the other output shaft and an opposite end and an output link has one end pivoted at the one roller of the other roller pair and has an opposite end pivoted on the opposite end of the input link. An intermediate gear pivoted on the opposite ends meshes with and interconnects the input and output gears. Thus rotation of the other output shaft is transmitted from the input gear through the intermediate gear and output gear to the one roller of the other roller pair.

Filament drawing frame with variable roller-pair spacing

A draw frame of a sliver-drafting apparatus has three cascaded roller pairs whose lower rollers are driven by respective motors at speeds determined by associated frequency dividers and/or multipliers in the output of a common oscillator of adjustable operating frequency. The slivers drafted by the roller pairs form, after doubling or plying, a fiber bundle traversing a thickness sensor whose output, integrated over predetermined time periods, is used by a microcomputer to ascertain optimum nip-line spacings and contact pressures reducing the thickness variations to a minimum. These parameters can be varied by horizontal slides supporting the roller pairs and spring-loaded blocks acting upon the shafts of the upper rollers; the positions of the slides and the pressures of the loading springs are adjustable by servomotors, under the control of the microcomputer, on the basis of a running-in program in which different combinations of values for the spacings and the pressures are successively set up and the combinations yielding the highest degree of uniformity are subsequently re-established.

Method of controlling fiber-drawing apparatus

Means for controlling fiber-drawing apparatus

Spinning frame, preferably ring spinning frame

An assembly of filament-drawing rollers, used for stretching rovings or fiber bundles in a spinning machine, is divided into a plurality of stages each including an elongate driven roller and a set of coacting counterrollers, the driven rollers being interconnected at both ends by respective gear trains for rotation at predetermined relative speeds by a motor driving one of these gear trains. In order to prevent any overstressing of the mechanism if nonmatching gears are inadvertently inserted into the two gear trains, a torque limiter in the form of a shearing bolt or a friction clutch is interposed between at least one driven roller and an associated driving gear. Advantageously, the torque limiter is provided with a device generating an alarm signal upon relative rotation, due to overload, of its input and output shafts respectively joined to the driving gear and the driven roller.

Filament-drawing assembly for spinning machine

A long spinning machine, preferably a ring spinning machine, with a plurality of drawing means, which serve to draw the fiber strands with the drawing means being arranged adjacent to each other and extending lengthwise of the machine the drawing lower rollers of the drawing means formed by a plurality of long roller lines positively connected together at one point by drive gear transmissions which provide predetermined rpm ratios between the roller lines with some of the roller lines connected together by additional drive gear transmission at least at one additional point spaced from the one point to eliminate or substantially reduce torsion in the roller lines.

Draw roll drive arrangement

A ring spinning or twisting machine has rotating rings which are equipped with metallic flanges. Each ring has an associated permanent magnet device which can be moved to the vicinity of the flange so that the magnetic field interacts with it and generates eddy currents which tend to decelerate the rotating ring. The permanent magnets are mounted on a common sliding rod which is actuated by a servomotor. The displacement is such that each magnet moves substantially parallel to the plane of the flange and may occupy a position where the magnetic field is laterally adjacent to the flange and does not interact with it.

Ring spinning or twisting machine

A thread breakage repair apparatus for use in open-end spinning machines includes a fixture which holds the thread and trims its broken end and it also includes a movable assembly, on which a drawoff tube is mounted which is connected to a source of suction. This drawoff tube is brought close to the end of the thread held by the clamping and severing fixture, whereupon a controller releases the clamped thread which is then aspirated into the interior of the drawoff tube. The mechanical transport mechanism for the thread may be reversed in motion by the controller, permitting already spun thread to be backspaced so that the end of the thread may be reattached to the fibers located in the spinning rotor. The drawoff tube may also be of the telescoping type whose extension is determined by the controller.
