Abstract (en)
[origin: WO9103363A1] A former (18) is initially moulded to have a relatively thick wall (average about 2mm) with an outer shape forming surface and an inner surface defining a hollow, and a hollow extension (20) which extends from one end, and the shape forming surface has a liquid coagulant (22) applied to it and is subsequently immersed in a liquid latex (25) which sets over the former (18), whereupon the former (18) is evacuated of air and therefore reduces its volume and the relatively thin latex skin (29) (average about 0.25mm thickness) is removed from the former (18).
