Abstract: The invention relates to an apparatus suitable to be used in an installation ensuring the progression of long, flexible and deformable products, said apparatus comprising means for limiting, at will, the size of the turns, which means are adjustable by displacement in a direction substantially perpendicular to that of the progression of the products.

Abstract: A handling installation designed for supporting, displacing and stacking loads in predetermined positions comprising, in combination, at least one load storage zone having at least one gangway extending therein, the or each gangway being provided on either side with fixed members comprising an upper track and a lower track, and a vehicle having tired support wheels for carrying the vehicle on the floor external to the or each gangway, and being further provided with flanged metal rollers for supporting the vehicle on the lower track during movement of the vehicle along the or a chosen gangway, the flanged metal rollers including inner flanges for guiding the vehicle on the lower tracks and the vertical spacing between the upper and lower tracks being sufficient to provide clearance for the flanged metal rollers while ensuring stability of the vehicle against any tilting movement of the vehicle when the vehicle is under load in the gangway.

Abstract: An apparatus for conveying elongated flexible material such as metal strips, wire and tubes by means of rotating shafts in a processing container holding a treatment-fluid for treatment of the material chemically, electrolytically, by pickling, deposition and similar processes, provides for the means of: coiling the material, imparting the coiled material the shape of a helix having a plurality of loops; causing at least a partial immersion of the loops of the helix in the treatment-fluid; advancing the helix in the said container at an advance speed; controlling the entry speeds of the helix relative to a predetermined speed withdrawal of the helix from the container.In a preferred and more efficient mode of treatment, the inlet speed of the helix exceeds the exit speed with a consequent slow and progressive increase of the length of the helix immersed in the treatment-fluid at a time in a first phase of the operation.

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.
