Abstract
A pneumatic needle threading assist is disclosed which has a thread collecting chamber in which, due to the air flow therethrough, thread having passed through the eye of a sewing needle, is therein deposited in a series of spiral loops limiting the amount of thread in the vacuum line and preventing the vacuum source from being contaminated with the thread.
