It is an object of the present invention to provide a spinning device that detects early that fibers F have been accumulated in an air exhausting spaceto prevent a defect (weak yarn) in a spun yarn. A spinning device in accordance with the present invention includes a pneumatic spinning nozzlea whirling current generating chamberin which fibers are twisted using a whirling air current generated by the pneumatic spinning nozzle, an air exhausting spacethat is in communication with the whirling current generating chambera negative pressure source that sucks air from the air exhausting spaceand a pressure sensorthat detects a pressure in the air exhausting spaceWhen the pressure detected by the pressure sensorduring a spinning operation performed by the pneumatic spinning nozzlerises to at least a predetermined value, the unit controllerperforms control such that the spinning operation is stopped. The unit controllerfurther lights an alarm lamp

Spinning device and method for detecting fiber accumulated state

To provide a clump cutter apparatus of an elastic yarn for improving a success ratio of clump cutting when cutting the elastic yarn running in a draft state. A clump cutter apparatus of an elastic yarn configured by overlapping and combining a plurality of laminate layer blocksforming a penetrating yarn running path RP for allowing running of a yarn to a direction of a yarn running, wherein the plural laminate layer blocks include first and second slide blocksandand the clump cutter apparatus comprising: yarn holding meansfor holding the yarn in the yarn running path due to movement of the first slide block and yarn cutting meansfor cutting the yarn due to movement of the second slide block after holding the yarn by the yarn holding means.

Clump cutter apparatus of elastic yarn

A spinning apparatus having a nozzle n1 that applies a rotating air current to fibers f and a hollow spindle s1, wherein a fiber introduction member E with a fiber guide surface e8 having a torsion angle of 100.degree. or more is disposed, without a needle shaped guide member e2, near the tip s1' of the fiber introduction side of the hollow spindle. Since the torsion angle of a fiber guide surface of the fiber introduction member is 100.degree. or more, fibers can be bundled easily without the needle shaped guide member and leaves and other foreign matter contained in a sliver are prevented from accumulating between the fiber introduction member and the hollow spindle, thereby reducing the frequency of yarn breakage and improving the spinning capability.

Fiber spinning apparatus having fiber twisting guide

A fluff cleaning truck moves along the textile machine being operated to efficiently and automatically remove fluff. The cleaning truck is loaded with cleaning members and travels along the frame of a textile machine and stops at a desired position to clean at all once desired portions of the textile machine being operated by unit of plural spindles.
