Abstract (en)
A drainage foil comprising a hard wearing nose portion that includes the leading edge of the foil and which is normally permanently fixed to a web forming machine. The trailing part of the foil is detachable and has an upper surface parallel to, or at least in part downwardly inclined to, the upper surface of the nose portion. Among the advantages of the arrangement is the ability to alter the drainage effect of foils in a web forming machine by removal or substitution of the detachable portion while the machine is running so that the web forming cloth is supported during such interchange or removal and so that the nose portion is not damaged by the handling involved in removal or substitution of a foil.
