摘要:
A textile machine made by assembling a plurality of unit textile machines. Each unit textile machine is provided with a plurality of unit machines, and each unit machine is provided with a yarn package forming mechanism. Each unit textile machine is provided with a unit conveyer belt disposed along a longitudinal direction of the unit textile machine at a position adjacent to the yarn package forming mechanisms. When the unit textile machines are assembled as one body, their unit conveyer belts are aligned and form a combined conveyer belt. At least one step is provided between any two adjacent unit conveyer belts or a unit conveyer belt of a unit textile machine and an auxiliary conveyer belt mounted on a head stock of the assembled textile machine. So as to always maintain the assembled conveyer belt in a clean condition, a cleaning device may be disposed at a position between two adjacent unit conveyer belts.

A device for damping the vibrations and the vibrational force between a structural element in a vibrational state and a peripheral or adjacent element exposed to the vibrational force and the sound incidental to the vibration. In the device, a block-shaped means consisting of a vibration and sound-proof material has on at least at one side thereof irregularities consisting of raised and depressed sections and this block-shaped means is interposed between the two elements so that the configuration consisting of the raised and depressed sections will dampen the vibrational force and the sound incidental thereto.

An automatic method and apparatus is furnished for transporting yarn packages formed on the cylindrical tubes by a conveyer belt disposed adjacently along a textile machine or a group of textile machines and for transferring the yarn packages from the conveyer belt to receiving rods of a transporting means. In the apparatus, an auxiliary device for correctly transferring the yarn packages from the conveyer belt to the transporting means is satisfactorily utilized.

Two mirrors are placed in such a manner as to line in a Z-axis direction in a beam irradiation head. These mirrors are located at a position beyond a normal scan range of the laser light in the Z-axis direction and within a limit range of scanning of the laser light, and the angles of inclination of mirrors are adjusted so as to reflect incident laser light toward a PD. In the case where a lens is driven in a Z-axis direction (a lateral scanning direction), driving current values Ia, Ib of an actuator at the times when reflected light from these two mirrors enters the PD at the maximum light quantity are detected. A driving current Imz required to position a lens for irradiation at a neutral position and a drive amount Δzd of the lens for irradiation per a unit driving current are then determined based on the detected driving current Ia and Ib.

There is disclosed a flavor and test composition for a chewing gum which has an effect of extending release of a flavor and taste of the chewing gum and is constructed by coating or melting and dispersing a flavor and taste substance which is an essence of expressing the flavor and taste, wherein a material used for the coating or the melting and dispersing of the flavor and taste substance is composed of a substance group comprising sterols as main ingredients. There is also disclosed a chewing gum which contains the above mentioned flavor and taste composition for a chewing gum.
摘要:
A method of yarn piecing in a fasciated yarn spinning unit is disclosed by which a yarn having a broken end and drawn out from the yarn package is introduced through the false-twisting nozzle by conducting an intermediate portion of the yarn into a slit which is formed on a lateral side of the nozzle and extends to the yarn passage channel in the nozzle. Because the yarn has been previously cut into a predetermined length thereof, the cut end of the yarn is placed in the drafting zone of the drafting mechanism at a position where the cut yarn end overlaps a broken end of the fiber bundle. By restarting the spinning operation, the overlapping ends of the yarn and fiber bundle are drafted properly in the drafting zone and then the fibers in the overlapping ends are intermingled by the false-twisting effect of the rotary stream of jetted air while they are advanced through the false-twisting nozzle.
摘要:
A drafting arrangement including a collector means suitably utilized for fasciated yarn spinning. The collector means in the shape of a hollow shell is disposed between a preceding draft means such as a pair of front rollers and the post draft means such as a pair of a aprons, in such a manner that a front surface of the collector means confronts a rearward surface of the preceding draft means and, on the other hand, a rear surface of the collector means confronts a front surface of the post draft means with a predetermined clearance. By this construction, a concomitant air stream accompanying rotation of the draft means is effectively expelled out of the fiber passage and stable drafting can be accomplished.
