[Class 17 (i)] Stiffeners, machines for.-The machine described in the parent Specification for moulding a counter having a waist extension curved heightwise of the counter, as described in Specification 272,171, [Class 17 (ii)], is provided with modified means for preventing the pressure between the wiping device and the counter flange increasing undesirably while the waist portion is being operated on. The machine is of the kind described in Specification 268,032, [Class 17 (i)], having a main wiper 1 to which a second wiper 15 in advance of the first is pivoted by arms 3. The wiper is itself pivoted to the arms on a shaft 19, a spring 21 urging the wiper to normal position. A pair of springs 5 urge the arms 3 towards the moulds. Each of the outer moulds carries a rail 33 adjustable at right angles to the path of the main wiper and shaped to engage the wiper 15 as it passes on to the waist portion of the stiffener, to prevent the pressure of the wiper on the flange increasing unduly. In a modification, the pivot 47 of the lower wiper is restrained by toggle links 61, 65, the intermediate pivot being urged upwardly by a spring 75 threaded over a rod 71 engaging the pivot. The wiper is urged anticlockwise by a spring 59 and is curved to a smaller radius than the waist portion of the moulds, so that it may tip clockwise as it engages the waist portion. When this occurs the link 65 swings clockwise, reducing the efficiency of the toggle linkage by bringing the links 65, 71 more nearly parallel, and thus preventing undesirable rise of pressure on the wiper.
