Abstract

The size of the synthetic yarn is sensed on the fly with a base plate carrying a roller over which the yarn runs. The roller is pressed by an arm pivoted on a plate and featuring a ceramic bush contacting the yarn. The arm carries the core of an electromagnet and its position determines the admittance of the s.c. fed coil.
