Apparatus for monitoring size encapsulation of yarn on a slasher

摘要

A method for quantifying size encapsulation of yarn on a slasher comprising measuring the hairiness of yarn entering a slasher prior to the application of size to the yarn, measuring the hairiness of the yarn leaving the slasher and solving the equation: <IMAGE> Apparatus for quantifying the size encapsulation of yarn on a slasher comprises an entry hairiness sensor positioned at the entry side of a slasher, a delivery hairiness sensor positioned at the delivery side of the slasher, the entry and delivery sensors producing signals proportional to the hairiness of the yarn at the entry and delivery sides of the slasher respectively, and a computer for solving the above indicated equation and producing an output signal representative of size encapsulation.
