Abstract

See full text

A pattern data processing system configured to determine and compensate for any points of entanglement between different yarns. A point of entanglement is defined as a point where the yarn from one needle crosses and traps the yarn from another needle on the back face of the backing medium. The pattern data processing system is configured to calculate the additional length of back stich caused by each point of entanglement by subtracting an ideal back stich length, calculated as the path which would have been taken by the yarn had it not been entangled in another yarn, from an actual yarn path, calculated as the actual length of the entangled yarn. A controller is configured to include in the amount of yarn fed by a respective yarn feed mechanism for each stitch an amount equivalent to the additional length of back stitch. The invention also includes a tufting machine and method of operating the tufting machine with the pattern data processing system.
