A traverse device in which rotary members each having yarn guide blades are arranged to be overlaid and rotated in the direction opposite to each other, and a traverse guide member is provided along the motion locus of the yarn guide blades, wherein the number of the yarn guide blades of the rotary members is differentiated, and the rotary speed is differentiated by a reciprocal number of the ratio of the number. The traverse of yarn and speeds of forward path and backward path are differentiated, and the number of windings between the forward path and the backward path is changed.

In an automatic winder, the tension device provided on each winding unit has a tenser in contact with a yarn to apply a resistance thereto, and a driving actuator of said tenser member, and each of the actuators provided on each winding unit is associated with a control device positioned separately from each winding unit, and adjustment of the tenser member is remote-controlled. The control device is used to vary the yarn tension in accordance with amount of yarn layer on a package, winding speed of a yarn and the like.

A bobbin transfer system consisting of a pair of conveyors, one to carry the spinning bobbins and the other to carry the empty bobbins, each installed at a top portion of a spinning machine to run along the spindle row. The spinning machine and a winder may be connected with each other by the conveyors.
摘要:
The object of the present invention is to obtain a contact pressure control device capable of carrying out feedback control enduring a practical use by inventing a pressure detecting means and the employment structure of the same. The contact pressure control device of the take-up winder comprises a bobbin holder 5, a contact pressure roller 11 contacted against the bobbin B set on the bobbin holder 5, a slide supporting mechanism (s) for supporting the contact pressure roller 11 elevating or descending to the machine main body 2, and a contact pressure cylinder 13 freely adjusting the contact pressure of the contact pressure roller 11 and the bobbin holder 5. Moreover, a load cell 16 is provided directly below one contact pressure cylinder 13 located between a pair of slide supporting mechanisms (s), (s). Furthermore, a print circuit board for controlling is provided for controlling the contact pressure cylinder 13 based on the detected value of the load cell 16 so that the contact pressure is to be maintained at a designated value.

An apparatus for controlling rotation of a drum comprises a controlling device which controls, upon winding, an invertor such that a motor for driving the drum which is adapted to be contacted with and rotate a package may be rotated at an optimum rotational speed in accordance with winding conditions of each of winding units of an automatic winder and which controls, upon doffing, the invertor such that rotation of a package which is effected in order to wrap an end of a yarn of a package around a bobbin may be carried out by the drum.
摘要:
The present invention provides a method of controlling yarn joining operation on the basis of signals provided by a slub catcher which generates a yarn breakage signal upon the detection of a slub during winding a yarn being supplied from a yarn supply bobbin on a take-up package. A change of a yarn supply bobbin for a new yarn supply bobbin and a yarn joining operation are conducted upon detection of the slub catcher whether a yarn breakage is occurred and/or detection of the yarn absence under what conditions.
摘要:
A device for finding an end of a yarn whereby an end of a yarn connecting to a layer of the yarn on a bobbin is found and is inserted into a center hole of a bobbin. The device includes an air flow controlling plate located near an outer periphery of a layer of a yarn on a spinning bobbin and a compressed air injection nozzle located in a gap between the air flow controlling plate and the yarn layer of the spinning bobbin.
