Abstract:
An apparatus, comprising:at least one circular knitting machine; at least one beam having a plurality of yarn ends wound thereon for supply of said yarn ends to said at least one circular knitting machine; a control system for continuously synchronizing the operations of said at least one beam with intake of yarn by said at least one circular knitting machine for proper supply of said yarn ends from said at least one beam to said at least one circular knitting machine; said control system comprising at least one central processing unit; at least one rotational sensor system that detects a movement of a mechanism of said at least one circular knitting machine and transmits a first input signal to said at least one processing unit; at least one periphery sensor system that detects variations in a radius of an outer layer of said yarn ends wound around said at least one beam and transmits a second input signal to said at least one central processing unit and; at least one compensator sensor system that detects movement and direction of at least one compensator and transmits a third input signal to said at least one central processing unit; said at least one central processing unit transmitting an output signal for continuous control of at least one beam rotating device to control a rotational speed of said at least one beam based on said first, second, and third input signals to synchronize said rotational speed of said beam with intake of yarn by said at least one circular knitting machine.
