Abstract

An anti-ballooning apparatus for a bobbin creel arranged between a bobbin mounted upon a bobbin holder of the creel and the thread guide and thread monitoring device operatively associated with such bobbin. The anti-ballooning apparatus prevents contact and/or entanglement of the thread balloon formed during withdrawal of the thread from the bobbins of the creel. This anti-ballooning apparatus comprises two parallel rods located at the central region between the thread guide and monitoring device and the bobbin and extending in a plane perpendicular to the thread withdrawal direction. These two parallel rods can be moved out of their functional or operational position parallel to themselves away from the bobbin holder into a manipulation position where their spacing from the end of the bobbin holder renders possible withdrawal or doffing of a bobbin mounted on the holder and equally donning a bobbin onto such holder.
