ABSTRACT:
An apparatus including combined means to control the size of helicoidal loops of an elongated flexible material and the linear speed of said material carried by horizontal rotary shafts and dipping into a treating agent inside a volume: the material inlet speed controls the speed of one of the shafts; it is positively driven up at the outlet; the effective linear speed inside the volume and the size of the loops are controlled by combined drives using different frictional properties of the material against the shafts and one wall sector of the volume, suitably covered for short temporary stopping contacts.
