A cleaning device for cleaning a nozzle in a spinning apparatus in which the nozzle unit is supported movably and a suction pipe for sucking yarn waste is oscillatingly supported so that a suction opening of the suction pipe can be moved to a gap between the draft part and the nozzle unit moved away from the draft part.

Cleaning device for cleaning a nozzle in a spinning apparatus

A draft device in a spinning machine comprising a pair of back rollers, a pair of middle rollers each provided with an apron belt, and a pair of front rollers. An outer peripheral part of the driving-side of middle roller is formed of a rubber.

Draft device in spinning machine

An operation starting method for a spinning machine of the type wherein a draft device, an air jetting nozzle and a false twisting device of the nip belt type are disposed in this order, constituted such that, in a condition of the false twisting device wherein belts are held in contact with each other at a nip point, when operation of the spinning machine is started, an air flow directed toward the false twisting device is produced on the air jetting nozzle side of the false twisting device while another air flow directed away from the false twisting device is produced on the opposite side of the false twisting device to the air jetting nozzle.

Operation starting method for spinning machine

A belt type false twisting device for a pneumatic spinning apparatus in which a fiber bundle is nipped between a pair of endless belts running in an intersecting relationship in mutually different directions to impart false twists to the fiber bundle. A pulley around which each of the endless belts extends is supported for rocking motion around a support shaft.

Belt type false twisting device

A spinning apparatus comprising a drafting device, an air jet nozzle and a false twisting unit including a pair of endless belts lying in surface contact with each other at a yarn nip point, the drafting device, air jet nozzle, and false twisting unit being located in a path of yarn travel in the order named, the air jet nozzle and the false twisting unit being both movable away from the path of yarn travel, the air jet nozzle and the false twisting unit being movable to and away from each other.

Spinning apparatus

The belt type false twister, in which a pair of pulleys with two travelling endless belts entrained thereabout are mounted fixedly, and in a position off the fiber nipping point of one endless belt there is disposed a roller for urging the said one endless belt toward the other endless belt, a linear travelling portion of the one endless belt being bent and allowed to come close to the other endless belt by the said roller to nip fibers between the closely adjacent belt portions.

Belt type false twister

An apparatus for manufacturing spun yarn comprising an air jet nozzle and a belt type twisting device, the nozzle having a fiber bundle outlet facing the twisting device and including a fiber bundle guide which is connected to the fiber bundle outlet and has a rear end located close to the intersection of the two belts defining the twisting device.

Apparatus for manufacturing spun yarn

An apron for a draft apparatus being suitable for use with a pneumatic high speed spinning frame. The apron includes a front side rubber layer, a reverse side rubber layer adhered to the front side rubber layer and core cords interposed between the two rubber layers. The peripheral borders of the apron have such a construction that one of said rubber layers is retracted from the other of the rubber layers.

Apron for a draft apparatus

An apron for a draft apparatus being suitable for use with a pneumatic high speed spinning frame. The apron includes a front side rubber layer, a reverse side rubber layer adhered to the front side rubber layer and core cords interposed between the two rubber layers. A ratio of thickness between the front side rubber layer and the reverse side rubber layer is set to a value within a range from 3:7 to 1:9.

A yarn eveness detector in a textile machine generates an analog signal in response to yarn uneveness. The analog signal is digitized and subjected to real time processing in a computer for analysis of both cyclic and non-cyclic yarn irregularity. A signal may be generated in response to irregularities exceeding a certain value.

Method and apparatus for analysis of information about yarn eveness

A method for evaluation of balloons of yarn-like materials. Ballooning of yarn-like materials is converted to an electric signal, the electric signal is amplified and the electric signal is analyed by a Fourier analyzer to know respective frequency components and voltage amplitude components which show the condition of ballooning.

Method for evaluation of balloons of yarn-like products

A method and apparatus for transmitting a driving power in a drafting device of a spinning frame. In the drafting device comprising a pair of back rollers, middle rollers and front rollers arranged in order, the driving power for the middle rollers is transmitted through a transmission passage different from a transmission passage for transmitting the driving power for the back rollers and front rollers.

Method and apparatus for transmitting driving power in drafting device

A high draft apparatus in a spinning machine for forming a spun yarn from a roving or sliver. The draft apparatus comprises back rollers, apron-provided middle rollers and front rollers and a gripping and a pressing means for a sliver disposed on the front end portion of the apron so that the arrangement of fibers in the drafted sliver is regulated and a high draft ratio can be attained.
