Patent ID: 7117900

Claim:
A method of forming an elastic woven tape, including the steps of: (a) providing at least two types of tape sections, each having a respective elongation and modulus; (b) integrating said at least two types of tape sections alternately and continuously with each other into said elastic woven tape by weaving; and (c) operating a thread feeding control device to control the speed of thread feeding; wherein said thread feeding control device includes at least one metal plate, at least two sensors, at least two sensor controllers, at least one straight-line operating motor, at least a pair of rods, at least one thread feeding motor, and at least one thread feeding device, wherein, during operation, a first of said at least two sensors inputs signals into a first of said at least two sensor controllers after having sensed said metal plate, wherein said first sensor controller processes the signals and controls said straight-line operating motor, wherein said motor changes the spatial position of said pair of rods, and wherein a second of said at least two sensors senses the change in the position of said pair of rods, and inputs signals into a second of said at least two sensor controllers, and wherein said second sensor controller processes the signals and controls said thread feeding motor, which in turn drives said thread feeding device.
