The invention further relates to an extruding die, an extrusion facility and to a method of operating the extrusion facility.

A length-adjustable adapter device (100) for connecting a plastics melt filtering device (200) to a pipeline (300), having at least a housing connection element (10) which has at least one inner flow duct (13) in a pipe extension (12) which is provided with an external thread (14), an adjusting ring element (20) having an internal thread (24) for receiving the external thread (14) of the pipe extension (12) and a line connection element (30) for connecting to the pipeline (300) with a line ring flange (31) and with a pipe extension (32) having an inner flow duct (33). The line ring flange (31) is rotatable in a receiving groove (23) of the adjusting ring element (20) and is fixed in a form-fitting manner against axially acting forces.

The present invention relates to a connection adapter for connecting two melt-guiding components having two adapter halves having connection means for connection to a respective one of the components and having connection means for connecting the two adapter halves to one another and having a melt-guiding piece that is adapted to a first of the melt-guiding components by a first opening cross-section and to the second of the melt-guiding components by a second opening cross-section. The invention furthermore relates to a melt processing plant having two melt-guiding components such as an extruder and a pelletizer that are connected to one another by such a connection adapter. In accordance with the invention, the melt-guiding piece is formed separately from the adapter halves and is tensionable against the melt-guiding components by the mutually connected adapter halves.

Calibration basket having exchangeable air guiding elements composed of porous material. The invention relates to a guiding device and to methods for guiding a plastic film, wherein the plastic film can be guided by means of an air cushion, wherein the guiding device comprises a plurality of blower elements (31) each having the foil owing features: at least one supporting element (35), at least one film-guiding element (34), which is at least partially porous, preferably microporous, and which is connected to the supporting element (35). At least one fastening element is provided, by means of which the supporting element (35) and the film-guiding element (34) can be detachably fastened to each other.

A device, to homogenise plastics material melts, has a homogenising element with a plurality of flow channels, which differ with respect to at least one feature from the group length, cross sectional area and cross sectional shape. When flowing through the homogenising element, the plastics material melt is divided into a plurality of part streams, which, in each case, flow through an associated flow channel. When leaving the respective flow channel the part streams have different flow speeds so the plastics material melt is expanded and sheared on transition to a uniform flow. As a result, a homogenisation of the plastics material melt takes place in a simple, efficient and effective manner.

A device (1) for filtering plastic melt having an inlet valve (14), an outlet valve (15) and a filter canister (2), wherein a cavity (3) closable by means of a cover (4) is formed and into which a melt channel (20) opens. In the filter canister (2) there is arranged a plurality of filter cartridges (5), which are each formed by a filter substrate (6) and a filter lattice (7). The filter substrate (6) comprises a wall having openings, said wall defining an internal space (8), which opens through an outlet (9) into a collection channel (10). The filter lattice (7) covers the openings of the filter substrate (6). The melt channel (20) is adjacent to the inlet valve (14) and may be brought into fluid communication with an outlet channel (16) via the inlet valve (14). The collection channel (10) is adjacent to the outlet valve (15) and may be brought into fluid communication with an outlet channel (18) via the outlet valve (15). The cover (4) fixes the filter lattices (7) onto the filter substrates (6).

An apparatus for controlling temperature of materials in a flowable state as they flow through a barrel. The apparatus includes a band surrounding the barrel having a plurality of connected blocks, each block having an inner surface in communication with the barrel. One or more of the connected blocks has a slot therein and has a removable, temperature controlling mechanism slidably received in the slot. A flexible cover surrounds an outer surface of the band with the flexible cover having a pouch for receiving a temperature sensing element.
