Abstract
A positive or active yarn feeding method and apparatus is provided which synchronizes the feeding of textile materials and provides encoding. The device includes a motor connected to an axle, on which a coupling spins the wheel and activates the belt. The motor receives signals from the positive or active feeding controller to adjust its speed. Connected with the main motor, the encoder outputs reference signals that incorporate production data derived with computers.
Claims7
An active feeding apparatus of an encoder for a knitting machine comprising:
- (a) an active feeding device,
- (b) a main motor with a coupling at a first side and a wheel mobilizing a belt at a second side;
- (c) an active feeding controller to receive a signal of a yarn feeding speed and a main motor speed, and then output an active feeding speed signal;
- and,
- (d) an encoder connected with the axle of the main motor to output a speed reference signal.
An active feeding method of an encoder for a knitting machine, comprising the steps of:
- (a) using an active feeding device composed of a motor activating wheel drivingly connected to a belt that turns a yarn storage feeding device which feeds a yarn composition into a knitting section;
- (b) using an encoder on an axle of a main motor to produce a signal that varies with a driving speed and is communicated to and received by a motor controller whose function is to compute a texture density and thereby derive a yarn feeding speed signal;
- and
- (c) synchronizing the main motor with said knitting machine which is devoid of a mechanism to manipulate a perimeter of a pulley disc and adjust a tension of said belt.
