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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.

An air bag apparatus to be mounted in a vehicle in order to protect an on-board passenger by unfolding and inflating a bag body when the bag body is activated. The air bag apparatus is equipped with an inflator, the bag body which is mounted in folded-up condition in such a way that the gas emitted from the inflator can flow into the bag body and equipped with gas vent holes, and a cover body for covering the bag body in the folded-up condition. Each gas vent hole is fitted with a gas-vent quantity regulating valve capable of decreasing the open quantity of the gas-vent hole during the time the bag body is inflating.
摘要:
In a seat structure having a side air bag device, a longitudinal groove (36) is formed in a seat back pad (14) along the longitudinal direction of the seat back pad, and an insert wire (40) which holds a seat outer cover, is embedded in the longitudinal groove (36). Bent portions (44) are formed in portions of the insert wire (40), which portions oppose the air bag device. Each of the bent portions (44) is bent in a substantially U-shaped configuration, and a slab pad (46) is wound around an outer peripheral portion of a base portion (44A) of each bent portion. Further, the bent portions (44) of the insert wire (40) are each provided to extend rearwardly and diagonally toward the inner side of a seat back (10) so that the embedded length of the insert wire (40) embedded in the seat back pad (14) is made longer, and adverse influences on riding comfort are thereby suppressed.
摘要:
An air bag against side collision, wherein two faces of mutually opposed peripheral wall portions having a substantially rectangular shape are connected by tethers in a strip or band-like shape whereby a distance of separation between the side wall portions in expanding the air bag is restricted. The expanded shape of the air bag is a substantially rectangular plate having four edges. An inner location near a rear edge accommodates an inflator supplying gas for expansion. Two side edges extend substantially parallel with each other from opposite ends of the rear edge and a front edge In a folded state, the front edge side of the air bag is cactus-folded such that the front edge side enters the inner side of the rear edge side of the air bag and approaches the rear edge. Tethers are connected respectively to the peripheral wall portions with a width dimension parallel with folds where the front edge side of the air bag is drawn in.
