    摘要： An apparatus for manufacturing a transversely aligned web has a spinning device provided with a plurality of nozzles for extruding molten polymer as filaments, and a conveyor on which the filaments spun by the spinning device are piled and traveling in a direction cross to the direction of array of the nozzles. The spinning device is provided with a high-speed fluid blowing unit for blowing a high-speed fluid in a direction parallel with a direction in which the filaments are extruded from the nozzles so as to attenuate the filaments. Further, the apparatus for manufacturing the transversely aligned web has at least one air stream vibrating mechanism for cyclically changing the flowing direction of the high-speed fluid blown from the high-speed fluid blowing unit in a direction cross to the machine direction of the conveyor. The filaments are vibrated in a direction cross to the machine direction of the conveyor, owing to the high-speed fluid by the air stream vibrating unit.

    摘要： A device for transversely stretching a web includes a pair of pulleys arranged in the substantially same plane and rotating in the opposite directions to each other and a pair of belts running around the pulleys, respectively. The web is widthwise stretched, by gripping opposite side edges thereof by the pulleys and the belts and conveying the web in a divergent manner. At least one pair of pressing rolls are provided at an inclination relative to the belts for pressing the opposite side edges of the web onto the belts prior to being gripped between the pulleys and the belts. According to this structure, a device for transversely stretching a web is realized which is capable of effectively preventing the web from being dropped from the grip.

    摘要： A non-woven fabric of the invention is characterized by comprising a filament layer wherein numerous filaments formed of a polymer material are spirally arranged as if numerous slender ellipses are arranged on a plane one beside another. It is produced by spinning a polymer material into filaments, vibrating the filaments, amplifying the vibration, and arranging the filaments in the form of an assembly of slender ellipses substantially in the direction of the major axis of the ellipse.

    摘要： An apparatus (20) for crimping a textile fibrous material (23), includes a pair of nip rolls (21, 22), a stuffing box (24) disposed adjacent to and downstream of the nip rolls, and a channel (44) disposed in a doctor blade (27, 28) of the stuffing box for the passage therethrough of a pressurized fluid and having an outlet (45) opening to an end surface (32) of the doctor blade through which the pressurized fluid is sent into a clearance (33) between the peripheral surface of each roll and the arcuate surface, the apparatus includes a seal block or plug (47) received loosely in a recess defined in the end surface between the outlet (45) and an outer end of the clearance. The plug (47) is urged mechanically or fluidically against the peripheral surface of the roll (21,22) to prevent leakage of the pressurized fluid from a stuffing chamber (31) in the stuffing box (24) through the clearance (33) to the outside air.
