Abstract
A machine for crimping yarns has an elongate chamber (14) with, at one end, an opening (15) for introducing the yarn (1) to be crimped and, at the other end, an opening (16) for exiting the crimped yarn. The wall (17) of the chamber (14) includes an elongate opening (18) parallel to the axis of the chamber, in which fingers (19) , uniformly distributed along the opening (18) are engaged. A drive (20) is provided for moving the fingers (19) in order to permit them to move the crimped yarn positively towards the exit opening (16) of the chamber (14).
