Claims

[Scope of Claim for Utility Model Registration] 1. A yarn feeding device for supplying yarn having elastic properties such as rubber yarn (hereinafter referred to as rubber yarn) in a knitting machine such as a sock knitting machine, which feeds the rubber yarn. A yarn feeder in which a guide roll is pressed into contact with a rotor for feeding the rubber yarn so as to rotate as the rotor for feeding the rubber yarn rotates, and the rubber yarn is supplied through between the rotor for feeding the rubber yarn and the guide roll. The device is equipped with a motor that independently rotates the rubber thread feeding rotor without being interlocked with the rotation of the knitting cylinder in the knitting machine, and a magnetic sensor mechanism is installed on the rotating shaft of the motor. A deceleration device for decelerating the rotation of the rotor is interposed between the motor and the rotor for feeding the rubber thread, and the magnetic sensor and the motor are each electrically connected to a control device for feeding the rubber thread. and transmits the detection information of the magnetic sensor to the rubber thread feeding control device,
A rubber yarn feeding device for a knitting machine, characterized in that an output signal from the rubber yarn feeding control device is transmitted to the motor to control rotation of the rubber yarn feeding motor by the motor. . 2. The magnetic sensor mechanism includes a plurality of rotating bodies having permanent magnetism and a magnetic sensor placed opposite the rotating bodies, and the rotating bodies are connected to a motor that rotates a rotor for feeding rubber thread. The rubber yarn feeding device for a knitting machine according to claim 1, wherein the rubber yarn feeding device for a knitting machine is fixed to a rotating shaft and interlocked with the rotating shaft of the motor.
