Abstract: Disclosed is an apparatus for the processing of plastics, with a container with a rotatable mixing, where, in a side wall, an aperture is formed, where a conveyor is provided, with a screw rotating in a housing, wherein the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, and wherein the ratio (V) of the active container volume (SV) to the feed volume (BV) of the container or of the cutter compactor (1), where V=SV/BV, is one where 4?V?30, where the active container volume (SV) is defined by the formula SV = D 3 ? ? 4 and D is the internal diameter of the container, and where the feed volume (BV) is defined by the formula BV = D 2 ? ? 4 · H , where H is the height of the intake aperture.

Abstract: A machine for the manufacture of a fibrous web includes a back liner former, a top liner former and at least one middle layer former. The back liner former is configured for producing a back liner, comprised of a fibrous web, with one side of the back liner having a higher fines content. The top liner former is configured for producing a top liner, comprised of a fibrous web, with one side of the top liner having a higher fines content. The middle layer formers, being configured for producing at least one middle layer, comprised of a fibrous web, with one side of the middle layer having a higher fines content, the other side of the middle layer having a lower fines content. Each middle layer former and the top former having couch rolls that define an associated couching zone; wherein the back liner former and each middle layer former are configured such that the side of the higher fines content of the back liner contacts the lower fines content side of the middle layer.

Abstract: A machine for the manufacture of a multi-layer fibrous web includes at least two fibrous web layers and at least two formers; the fibrous web layers each having a lower fines side with a lower fines content and a higher fines side with a higher fines content; and the formers include a first former and a second former, at least one of the two formers being a gap former, with the second former including a couch roll defining a couching zone whereat the lower fines side of the first fibrous web layer is brought into contact with the lower fines side of the second fibrous web layer.
