Abstract: A method and device for mixing plastic from liquid components in a mixer (8) and conveying it through a line (10) into a mould (12), in particular for vacuum infusion, characterised in that the components are each pumped by means of a pump (24) from their own respective component container (22) into a mixer (8) and are mixed therein, that these volume flows are controlled by a controller (26) in such a manner that they supply the components to the mixer (8) in a specific ratio, that the pressure loss in the line (10), between a pressure sensor in one of the component supply lines (32) leading to the mixer (8) and the mould (12), is determined, and that the pressure is measured by the pressure sensor and supplied to a controller (26) which, taking into consideration the determined pressure loss, controls the volume flows such that the pumps (24) supply the components to the mixer (8) at a pressure that is greater than the ambient pressure or than another specific pressure that should not be exceeded in the mou

Abstract: A device for evacuating a container that contains a pasty liquid to avoid air inclusions or bubbles in the liquid while the container is being filled and/or to eliminate air between the liquid surface and a follower plate until the plate contacts the liquid surface during insertion of the plate into the container before removal of the liquid. The device comprises a cover assembly to close an opening of a container in a vacuum-tight manner and which has a connection device for connecting an evacuation pump. A collapse avoidance apparatus is provided to surround at least one region of the outer faces of the container walls with a seal to connect to the wall outer face in a vacuum-tight manner and form a vacuum-tight collapse avoidance chamber. A connection device is provided for connecting an evacuation pump to evacuate the chamber and apply a vacuum on the wall outer face.

Abstract: A follower plate device for sealing and evacuating a container that has a cylindrical inner contour and contains a particularly paste-like liquid. The device comprises a seal arranged on a periphery of the device and designed so as to be able to be inserted into the cylindrical inner contour of the container such that it seals around the periphery, and marking the boundary between an outer side of the device and an inner side of the device, and a line extending through from the inner side to the outer side of the follower plate device, arranged on the outer side for connecting to a line connection leading further to an evacuation pump. The follower plate device further comprises a replaceable open-pored porous component through which the line is guided.

Abstract: The invention relates to a mixer insert having a support rod element and at least one vortexing element and a rotary drive connection structure, wherein the mixer insert, for insertion into a tubular passage element, and together therewith, is adapted to a device for mixing at least two fluid components to be placeable by means of the rotary-drive connection structure in drive connection with a driveshaft of the device, when the mixer insert is inserted into the passage element and the passage element is placed in fluid-tight flow connection with at least two component feed lines of the device, characterized in that the rotary-drive connection structure has a bore hole having a bore hole wall which are adapted to a thread on the driveshaft in such a manner that the bore hole, for producing the drive connection, can be screwed onto the thread, wherein the bore hole wall is shaped by the thread. The invention also relates to such a device for mixing and also to a system of such a device and such a mixer insert.
