Abstract

A wrap detector for detecting a yarn wrap on a roller, comprising a pivotally mounted butterfly-type sensing member arranged adjacent to the surface of the roller and having a predetermined normal position relative to said roller, apparatus allowing a limited range of angular deflection of the sensing member from the normal position, apparatus operative, when the limited range is exceeded, to move the sensing member through a greater angle to a limit position lying well clear of the roller, and a switch mechanism actuated by the sensing member when in the limit position to control further yarn feed.
