The present disclosure relates to a machine for an automated filling of a mold assembly for molding an ophthalmic lens, comprising: filling means to fill the mold assembly with a molding material through a filling aperture provided in the mold assembly, acquiring means to acquire an input value linked to the internal volume of the mold assembly, and control means for controlling the flow rate of molding material injected by the filling means in the mold assembly according to a flow rate profile deduced as a function of said input value.

An apparatus including a co-extrusion device for extruding a multi-layer structure having at least one primary layer and at least one secondary layer, so that the multi-layer structure leaves the co-extrusion device along an exit direction; a mould provided with a pair of elements, at least one of the elements being movable towards the other in a moulding direction, so as to compression mould an object from a multi-layer dose which was severed from the multi-layer structure; a transport device for carrying the dose towards the mould; an arrangement for modifying orientation of the dose while the dose is being transported by the transport device, so that the dose is introduced into the mould with an orientation in which the secondary layer extends transversely to the moulding direction.

Apparatus for feeding single grains to one or more processing machines comprising at least one singulating device, a granular material reservoir for a bulk material, and a feeding device for feeding the singulated bulk material to the injection molding machine. The singulating device is formed from a singulating disk provided with suction openings distributed over the pitch circle. On one side of the singulating disk, the granular material reservoir is arranged to hold bulk material. Via the shaft, the singulating disk is mounted to be rotated with the suction openings for receiving and dispensing grains. Furthermore, a grain scraper and/or a grain aligner for the bulk material or grains is arranged on the singulating disk in order to scrape off the grains and/or align the grains, or a stirring or carry-along element is arranged on the singulating disk for receiving the bulk material or on the shaft.
