Device for exposing the thread start of textile bobbins

摘要

Device for exposing the thread start of textile bobbins by pneumatic or mechanical means acting on the bobbin thread, the bobbin being suspended at one tube end in a rotatable clamping device. The rotatable clamping device consists of at least three rotatably mounted friction wheels, at least one of which can be driven and which bear simultaneously against the tube end and are staggered relative to one another in such a way that, as a result of their rotation, a pulling force directed onto the bobbin tube counter to gravitational force is exerted. <IMAGE>
