Abstract (en)
A method for pneumatic threading in a two-for-one twisting spindle of double hollow mandrel type, said method comprising seizing the initial portion (1) of wound yarn from the feed bobbin positioned about the lower hollow mandrel (40); seizing the initial portion (3) of wound yarn from the feed bobbin (2) positioned about the upper hollow mandrel (14) to drag it by compressed air injection to the outside of the spindle basket (7); joining the yarns of the two bobbins by means of a knot; and gripping the initial end (3) of the yarn of the feed bobbin (2) of the upper hollow mandrel (14) to pull it so that the two joined yarns of the two bobbins can be conveyed to the winding unit to commence twisting. <IMAGE>
