Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
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.
Claim 2
Dependent Claim
187 words
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.
Claim 3
Dependent Claim
43 words
A press according to claim 1, wherein the displacement means include a pair of guide columns and a vertical drive cylinder connected to said support and wherein the driving means of the vertical drive cylinder are synchronized with those of the moulding press.
Claim 4
Dependent Claim
35 words
A press according to claim 1, wherein the rotating brush comprises bristles having a length amounting to at least 10 mm and arranged in groups forming parallel rows which are spaced one from the other.
Claim 5
Dependent Claim
29 words
A press according to claim 3, wherein the rows of bristle groups are spaced one from the other by an angular distance in the range from 30* to 60*.
Claim 6
Dependent Claim
47 words
A press according to claim 1 wherein said horizontal guide has one end fixed to the movable plane and has the other end supported on the stationary plane by a roller to permit free movement of that end of the guide with respect to the stationary plane.
Claim 7
Dependent Claim
37 words
A press according to claim 1 wherein the brush is mounted for rotation on an axis which is disposed at right angles to both the direction of the horizontal displacement and the direction of the vertical displacement.
