Abstract
A method for pneumatic threading in a two-for-one twisting spindle having a double hollow mandrel. The method comprising seizing the initial portion of wound yarn from a bobbin positioned on the lower hollow mandrel in the spindle basket and feeding a sufficient length of it through the upper hollow mandrel to enable it to be then placed alongside the initial wound yarn portion unwound from the bobbin mounted on the upper hollow mandrel. The two initial yarn portions are then held jointly and rested on the mouth of the upper hollow mandrel, on which a head connected to a compressed air source is placed and pressed, in order to achieve pneumatic yarn threading.
