Combination of a press for moulding plastic materials,rubber and the like and a cleaning device incorporated integrally in the press

Claim 1

An improved press for moulding plastic materials, rubber and the like, comprising two mould halves, one half being movable in a variable plane and the other mould half lying in a stationary plane, a device integral with said press mould and movable with respect thereto for removing residual material adhering to the surface of said press moulds, said device comprising a rotating brush and displacement means for the brush and movable in two perpendicular directions for allowing the horizontal and vertical displacement of the brush and also movement of the brush in a direction which is a resultant of said horizontal and vertical displacement in synchronism with the movements of the movable plane of The moulding press to thereby permit the rotating brush to reach every point of the mould cavity, said displacement means comprising a horizontal guide which is laterally offset from said planes and which extends in the direction parallel to the direction of movement of the movable plane, and a support supporting the ends of the brush for rotation within the support and including a guide connection connecting the support to the horizontal guide.
