A draw frame for a spinning machine is provided with roving blocking mechanism associated with its inlet rollers actuable on rupture of the remittant thread to arrest movement of the roving and is further provided with a sensor for detecting the continuity of the roving being fed from a source of supply and a roving clamp situated between the sensor and the blocking mechanism. The blocking mechanism and the roving clamp are arranged to be simultaneously operated in response to a signal from the sensor or in response to rupture of the thread.

Roving blocking mechanism on draw frames of spinning machines

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

A row of spindles carried on a common rail have whorls in tangential contact with a driving belt urged toward the spindle axes by pressure rollers offset therefrom, the whorls being of a diameter on the order of half the roller diameter. Each whorl is journaled on an upper end of an upright, stationary shaft supported by the rail through two vertically separated elastic retainers.

Spindle mounting for ring spinning machine

A textile machine such as a spinning machine has, for each spindle, a comparator which senses the voltage at a motor driving said spindle and compares it with a reference voltage. Upon the comparator sensing such a change in the motor voltage as would be consistent with breakage of the material being worked on the machine (e.g. a roving passing towards the spindle and being spun into a thread), it operates a switch which serves both to switch off the motor driving the spindle and to arrest the material passing to the spindle.

Textile machine shut-off device

A bobbin drive has a support whose upper and a lower wall contain a motor with upper and lower shaft portions projecting through these upper and lower walls. A bobbin-support spindle is fixed on the upright shaft above the upper wall. A lower journal partly immersed in a lower body of oil carried in a lower sump rotationally supports the lower shaft portion adjacent the lower wall. An upper roller or ball bearing rotationally supports the upper shaft portion adjacent the upper wall and is lubricated from an upper oil reservoir provided immediately therebelow.

Bearing support for bobbin-spindle drive

Spinning or twisting machine

An assembly of motors designed to drive a ring rail, a bank of spindles and a plurality of draw or delivery rollers in a ring spinning or twisting machine is supplied with three-phase current of a frequency determined by the settings of digitally adjustable frequency selectors independently controlling respective solid state frequency-inverters assigned to the several motors or groups of motors. The selectors include frequency dividers in the output of a common and preferably also adjustable source of timing signals which may be a free-running oscillator or a pulse generator driven by one of the motors acting as a master.

Driving assembly for ring spinning or twisting machine

An assembly of fiber-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 rotated at predetermined relative speeds with the aid of several motors including at least one pair of synchronous motors positively coupled with a drawing roller at opposite ends thereof. These synchronous motors are energized with three-phase current of a frequency determined by the setting of a digitally adjustable frequency selector controlling a solid-state frequency inverter. The selector comprises a frequency divider in the output of a preferably also adjustable source of timing signals which may be a pulse generator driven by a motor coupled with another drawing roller.

Roller drive for draw frame

A method of producing a mountable tube for use with a textile spindle and the article produced by the method is revealed herein. The mountable tube is produced by cylindrical hammering of a steel body which may be provided interiorly thereof with a perforated insert body incapable of being deformed under the hammering process, but capable of being held within said mountable tube subsequent to completion of the hammering operation. The insert body is arranged to support the mountable tube on the textile spindle.

A mechanism for rotating a cannister during the filling of the cannister with textile material from a carding machine or the like which includes a turntable rotatably mounted on a frame for supporting a cannister having a movable bottom including a plurality of flexible metal bands arranged on the frame for reciprocating movement between a retracted and an extended position with upper end portions in angularly disposed relationship, the upper ends of the bands secured together for underlying engagement with the cannister bottom and the adjacent side edges of the bands provided with releasable interlocking means engageable during the movement of the upper portions of the bands into the extended position to form a pillar together with drive means for moving the bands between the retracted and extended positions to permit downward movement of the cannister bottom during the filling of the cannister with textile material.

Cannister rotation mechanism

A mechanism for rotating a cannister during the filling of the cannister with textile material from a carding machine or the like which includes a turntable mounted on a rotatably driven housing, the turntable being arranged to support a cannister having a movable bottom, a spiral spring having a lower end positioned in the housing with a support member on its upper end in underlying engagement with the cannister bottom for urging the bottom into an upper position together with a power driven winch disposed in the housing having a cable connected to the support member for lowering the cannister bottom downwardly against the force of the spring during the cannister filling operation.

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

Disclosed is a cannister rotation mechanism for use in combination with a fiber carding or drawing frame having a turntable arranged to deliver fiber into the cannister. Reciprocable means are shown for raising and lowering the movable cannister bottom into position to receive the fiber and later to remove the filled cannister and insert a new cannister for filling. Several embodiments of the reciprocable means are shown and described.
