The invention relates to a device for the continuous treatment of a semi-worked filamentary of strand-like metal material of indefinite length, arranged helically, of which the turns, supported and driven by rotating horizontal shafts, are immersed in a treating agent. An apparatus of this kind comprises two capstans or winches fitted with idle satellites or rollers; two strands of material coming from delivery units are bent thereon and assume the shape of two helices supported and driven respectively by pairs of horizontal shafts, and immersed in a treatment agent contained in a tank. The two helices rotate in opposite directions their turns interpenetrating, so that they guide each other; the size of each turn is regulated at the same time, if it increases, by its possible contact with one of the shafts bearing the other helix, and by the distance, adjustable during operation, between the two shafts of the pair bearing it. The system can be applied to all surface treatments, such as pickling, coating or deposition, carried out on filamentary or strand-like metal materials, particularly in wire-drawing.
In apparatus for treating flexible resilient filamentary material of indefinite length, a tank having a longitudinal horizontal axis extending from an entrance end to an exit end thereof, first and second shafts journaled over said tank for rotation about respective first and second axes spaced horizontally a predetermined distance and parallel with said longitudinal axis, first means guiding a first strand of material into said tank at the entrance end thereof to form a first helix comprising a multiplicity of axially-spaced loops each in contact with and supported by said first shaft with each loop passing adjacent and slightly spaced from said second shaft, second means guiding a second strand of material into said tank at the entrance end thereof to form a second helix comprising a multiplicity of axially-spaced loops each in contact with and supported by said second shaft with each loop passing adjacent and slightly spaced from said first shaft, each loop of each helix extending downwardly into said tank and intercalated between a consecutive pair of loops of the other helix, power means connected with said shafts and rotating the same in opposite directions, and means guiding in succession the loops of both helices out of said tank at the exit end thereof.
The method of continuously treating flexible resilient strand material of indefinite length, comprising, supporting on respective rotatable parallel first and second shafts horizontally spaced a predetermined distance and above a tank adapted to contain treatment fluid, first and second helices of said material with each loop of each helix extending into the tank and intercalated between a consecutive pair of loops of the other helix in the space between said shafts, each loop of each helix being normally spaced a short distance from the shaft supporting the other helix, and rotating said shafts at synchronous speeds and in opposite directions, whereby enlargement in diametral size of any loop of either helix results in contact of the enlarged loop with the shaft supporting the other helix to thus instantaneously augment the linear speed of the loop and correspondingly reduce the enlargement.
