Abstract
For false twisting apparatus (21) of the kind comprising three rotatable parallel shafts (10,11,12) arranged at the apices of a triangle and having a plurality of parallel discs (14) on each shaft (12) inter-digitating with the discs (14) on the other two shafts (10,11), a threading device (13) is provided allowing sequential threading of a yarn into the apparatus (21). The threading device (13) comprises a body (30) on which tines (40 to 44) are slidably mounted in spaced disposition longitudinally of the body (30) and which can be pushed sequentially into the spaces between consecutive discs (14) on two stacks (10,11) as separated by the discs (14) on the other shaft (12).
