<p>A moulding press of circular type with a central moulding drum and peripherally-mounted press shoes which axe movable to an inner closed position in which they press strip material to be mounded onto the surface of the drum. In their closed position, the shoes define an arcuate press surface extending part way around the drum and defining a gap exposing a portion of the drum surface in which portions of the strip material being moulded can be accommodated. This allows for moulding strip material in continuous form, and the surface of the drum has a contoured profile to impart a corresponding moulded surface on the radially inner side of the strip material in the press. The interengagement of the moulded strip and the drum retains the strip in register with the drum moulding surface when the drum is rotated to draw fresh strip material into the press and to allow moulded material to be withdrawn from the press through the said gap.</p> |
