ABSTRACT:
Winding apparatus for winding wire, thread or the like onto a flanged spool including a thread guide for traversing the wire or thread back and forth lengthwise of the spool during winding and means for detecting surface irregularities of the wound wire or thread in two zones each adjacent to a respective one of the spool flanges. The means for detecting surface irregularities comprises a buffer-accumulator located upstream of the spool, a linear speed sensor located between the spool and the buffer accumulator, and gating means for inhibiting the output from the sensor except when the thread guide is in a position to guide the thread or wire into one of said zones.
