A method for conveying a concave object having a lateral wall away from a mould comprises the steps of: providing a removing element, movable along a path, and a guiding element; extracting the object from the mould and releasing the object onto a supporting surface in a position interposed between the removing element and the guiding element, while the removing element is at a distance from the object; displacing the removing element towards the object, so that the removing element makes contact with the lateral wall; moving the removing element along a portion of the path, to convey the object towards a delivery position.

An apparatus comprises: at least one mould for forming an object from a dose of polymeric material; a conveying device having a central support rotatable about a first axis the conveying device comprising at least one conveying element movable along a first closed path for collecting the dose and subsequently releasing the dose in the mould; a removing device having a central body rotatable about a second axis, the removing device comprising at least one removing element movable along a second closed path for conveying the object away from the mould.

The first axis is distinct from the second axis and at least one point exists at which one path selected from between the first closed path and the second closed path overlaps another path selected from between the second closed path and the first closed path.

A molding apparatus includes a movable molding surface with molding cavities, a pressure shoe with a stationary outer surface that defines in cooperation with the molding surface a pressure zone, and a resin source configured to introduce molten resin into the pressure zone to be forced into the molding cavities by pressure in the pressure zone. The molding surface is movable with respect to the pressure shoe to introduce molding cavities to the pressure zone to be filled with resin while the outer surface of the pressure shoe and the molding surface define in between an entrance gap of decreasing width upstream of the pressure zone. The outer surface of the pressure shoe is spaced from the molding surface in the pressure zone to define a minimum gap at which the outer surface of the pressure shoe has a slope parallel to the molding surface. The pressure shoe is adapted to be held in a flexed condition against resin in the pressure zone while forcing resin into the cavities, with the outer surface of the pressure shoe curved upstream of the pressure zone.
