ABSTRACT:
A wiping system for removing liquids such as lubricant and coolant liquids from the surfaces of a metallic strip. The system comprises upper and lower wiper rolls for wiping the upper and lower surfaces of the strip. The wiper rolls each comprise a metal core and a porous resilient covering. At least one upper backup roll for said upper wiper roll and at least one lower backup roll for said lower wiper roll providing support for said wiper rolls; urging said wiper rolls against their respective strip surfaces resulting in the formation of a liquid bead on each surface of said strip at the entry end of the wiper roll nip; and engaging their respective wiper rolls at contact zones at the entry ends of which beads of oil squeezed from said porous wiper roll covers are formed. A suction assembly is provided for each bead to remove liquid therefrom. The upper and lower backup rolls may be replaced by substantially identical clusters each comprising two intermediate or backup rolls and three sets of caster bearings.
