Abstract: A roll quadrant conveyor for conveying strip material generally includes a plurality of support members for supporting a plurality of rolls around a quadrant roll of any desired wrapping angle and, further, a plurality of rolls journaled for rotation in the support members. The rolls are positioned on opposed sides of a conveyor centerline, with each roll positioned at an angle of less than 90° with the conveyor centerline. The rolls define a chevron pattern around the wrapping angle. The strip material, in motion, is centered on the conveyor by the rolls arranged in the chevron pattern. The rolls are profiled rolls.

Abstract: System to re-circulate the treatment material in processes of surface treatment and finishing, which can be employed in association with a pickling and/or acid washing plant (12) or in association with a plant (12) for metal-coating with heat, the plant (12) comprising at least one dip tank (13) containing the treatment material (11), which is caused to circulate advantageously in countercurrent to the material to be treated, which is advantageously strip (14), the treatment material (11) being able to consist of acid baths or molten metal, such as zinc or aluminum, the dip tank (13) comprising a discharge conduit (18) and a feeder conduit (17), the system comprising at least two vessels (16a-16b) which can be hermetically sealed and are of a type resistant to pressure and which are positioned in parallel and associated with the discharge conduit (18) and with the feeder conduit (17), each of the vessels (16a-16b) including an independent inlet closure (20) and an independent outlet closure (19), each of the

Abstract: A frictionless strip support for supporting a metallic strip conveyed along a feed path in a treatment process. The support including at least one hydrostatic chute including a plurality of confined hydrostatic chambers having apertures therein for a supply of a pressurized treatment liquid such as molten metal, and at least one pair of hydrostatic guides positioned downstream of the hydrostatic chute. Each hydrostatic guide has a confined hydrostatic chamber with apertures therein for supply of a pressurized treatment liquid such as liquid metal. The frictionless support also includes a pump of supplying the pressurized treatment liquid through the apertures and to the confined chambers such that the treatment fluid maintains the strip spaced from the hydrostatic chute and the hydrostatic guides by hydrostatic force of the pressurized liquid normal to the strip surface as the strip is conveyed across the hydrostatic chute and the hydrostatic guides.
