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.
Claims11
Apparatus for treatment of strip material by a fluid, comprising, a container for fluid, first and second strip-supporting, elongated shafts journaled for rotation over said container in spaced, side-by-side relation on parallel horizontal first and second axes, a comb fixed between and parallel with said shafts essentially in a plane determined by their uppermost elements and essentially coextensive therewith, said comb including upstanding teeth spaced therealong, and rotating means engaging and positively feeding the strip material at predetermined speed, into said container at one end of said shafts, thence upwardly over and in transverse contact with said shafts in a plurality of loops each and guided between consecutive pairs of teeth of said comb with each loop depending into said container for contact with treatment fluid therein.
