摘要： PROBLEM TO BE SOLVED: To provide a spinning apparatus reducing the amount of space required in the longitudinal direction of a spinning machine and resultantly affording a smaller gauge than that of the conventional apparatus. SOLUTION: A twin unit comprises two drafting apparatuses for drafting fiber strands and is applicable to the spinning machine. The drafting apparatuses contain a plurality of drivable bottom rollers and are arranged essentially mirror image-symmetrical to one another. Each bottom roller contains a region for drafting the fiber strand and each bottom roller has two bearing points. Each bearing point is arranged on each side of the region for drafting the fiber strand. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a funnel unit for a spinning apparatus, which improves a funnel unit capable of being disposed on the funnel support plate 3 of a spinning apparatus equipped with a funnel 4 for guiding a yarn and concentrically surrounding the yarn-receiving region 1 of a spindle 2, has a relatively simple and compact structure, is little worn, can simply be maintained, gives the large number of revolution in a small consumption energy, and has a funnel capable of being driven or braked. SOLUTION: This funnel unit for the spinning apparatus is characterized in that a peripheral wall 13 capable of being at least indirectly bound to a funnel-supporting plate 3 concentrically surrounds at least a bearing casing 11 through a space in the radial direction, and is bound to the bearing casing through cushion members 14a, 14b at a distance at least in the radial direction and in the axial direction, whereby at least the funnel 4, a shaft 6, a rotor 8, a driving casing 9, a stator 10 and the bearing casing 11 are separated from the peripheral wall 13 and the funnel-supporting plate 3.

摘要： PROBLEM TO BE SOLVED: To prevent formation of fiber accumulation on the inside of a transporting belt. SOLUTION: This spinning machine comprises plural spinning stations. Each of these spinning stations comprises a drawing device 4 and a condensing zone 6 arranged in the downstream and the condensing zone 6 condenses a drawn fiber strand 5. Each condensing zone 6 comprises a circulating air-permeable transportation belt 16 and the transportation belt 16 is guided on a slide surface containing a suction slit 20. Each slide surface 17 is arranged on a suction tube 18 extending along plural spinning stations and each slide surface 17 has a cover 30. The transportation belt 16 transports the fiber strand 5 beyond a nip line 24 bounding the condensing zone 6 to a separation point. The transportation belt 16 is guided without any support on a recessed place 35 immediately downstream of the separation point. The recessed place 35 continues every two spinning stations in the form of open groove and the groove can approach a transfer blower.

摘要： PROBLEM TO BE SOLVED: To provide an assembled apparatus for a spinning machine for condensing a drawn fiber strand, including a condensation zone arranged at the downstream of a pair of front rollers of a drawing apparatus. SOLUTION: The fiber strand is transported through the condensation zone by a conveyer belt having air permeability. The conveyer belt is guided on a sliding surface installed in the condensation zone to a part of a belt circulation route. A suction slit is included on the sliding surface. A deflection guide is arranged for the conveyer belt at a certain distance from the sliding surface. The deflection guide is designed as a freely rotatable reverse rod having a special form contour in the longitudinal direction. The reverse rod prevents fibers being accumulated in a gap between the sliding surface and the inner side of the conveyer belt.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for producing a core yarn from a staple fiber by a fluid guide. SOLUTION: This apparatus is equipped with a fiber supplying means 4 having a fiber guiding passage 13 equipped with a fiber guiding face 28 to guide a fiber F of a fiber structure into an opening 6c for insertion of a yarn guiding passage 7 and a fluid device to generate a vortex flow around the inlet opening 6c of the yarn guiding passage 7. The fiber guiding face 28 is faced to the yarn guiding passage 7 and the fiber F can be supplied to the inlet opening 6c of the yarn guiding passage 7 through the fiber guiding face 28 and thereby. A guide 5 for at least one continuous yarn C twined by the fiber F is further installed.
