ABSTRACT:
An improved system for operating a chain link fence weaving machine. The system includes an electronic motor coupled to a main spindle shaft of the weaving machine. A trough is disposed adjacent to a weaving blade attached to the main spindle and coupled to the weaving machine. The trough receives two intercoiled needles (picket) from the weaving blade for weaving the fence. The trough has first and second opposing portions positioned to receive the picket therebetween. A retaining slot extends between the first and second portions. The radius of the first portion of the trough is less than the radius of the second portion thereof to prevent the two intercoiled needles being woven in the trough from extending into the slot. An actuation mechanism opens and closes the retaining slot to frictionally engage or release a portion of the fence held in the slot. A control system is coupled to the motor for controlling the fabrication rate of fence being woven. The control system also controls the height and length of the fence being fabricated by the weaving machine.
