A moulding press of circular type with a central moulding drum and peripherally-mounted press shoes movable radially to an inner closed position in which they press strip material to be moulded 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surface when the drum is rotated to draw fresh strip material into the press and to allow moulded material to be withdrawn from the press through the said gap.

A press for moulding strip material, comprising a drum having an exterior circumferential moulding surface on which the strip material is to be applied, the drum moulding surface being formed with a contoured moulding profile for moulding the strip material with corresponding contours when it is pressed onto the drum, a stationary frame extending around the drum moulding surface, means rotatably mounting said drum on said frame for rotation about its axis, a plurality of press shoes being supported on said frame by means whereby they can be extended and retracted radially towards and away from the drum between an outer, inoperative position and an inner, closed position for pressing the strip material into conformity with the drum moulding surface, the shoes in their inner, closed position forming together an inwardly-facing arcuate press surface which extends circumferentially part way around the exterior of the drum and defines a gap between the ends thereof exposing a portion of the drum moulding surface, in which gap portions of continuous strip material to be moulded in the press can be accommodated.
