Abstract

A blocking device, preferably in the form of a baffle plate is provided behind the rollers of a thread tightener in a bobbin creel which can be pressed against one another, namely behind the roller pair in the direction of the through-passage. In case of a thread break, the baffle plate prevents the loose thread end from falling out of the roller tightener. Preferably, the baffle plate is latched onto a thread hoop and rotatably journalled, so that it can be swung from an operations position into a neutral position.
