    摘要： Disclosed are a continuous screen changer, a screen changing device, and an extruder. The continuous screen changer includes an external shell (10) with an internal cavity (11) and an internal drum (20); the external shell (10) is provided with a feed port (12), a screen changing port (14) and a discharge port (13). The internal drum (20) is provided with at least four filter screen mounting grooves (21) and material flow passages (22) correspondingly communicating with the filter screen mounting grooves (21), and a sealing wall (23) hermetically connected with the internal cavity (11) is formed between each two adjacent filter screen mounting grooves (21). After entering the internal cavity (11) along the feed port (12) and being filtered by a filter screen (40), materials flow out of the discharge port (13) along the material flow passages (22). The filter screen mounting groove (21) rotates to be opposite to the screen changing port (14), and the filter screen (40) on the filter screen mounting groove (21) is changed at the screen changing port (14). The continuous screen changer can implement continuous and uninterrupted change of the filter screens (40), so that the apparatus to which the continuous screen changer is applied can continuously work.

    摘要： An extrusion die (100) includes a plurality of studs (156), a tuning assembly (200) and a restrictor member (300). The tuning assembly (200) comprises a wedge member (202), first and second adjustment members (204), and an adjustment control (208) having a rotatable single point adjustment member (209). The wedge member (202) is coupled to first ends (158) of the studs (156) and includes a first and second plurality of channels (212, 213) within. The first and second adjustment members (204,206) have a plurality of protrusions (216), each of which is positioned within a respective one of the first and second plurality of channels (212, 213). The restrictor member (300) extends in the longitudinal direction and is coupled to second ends (106, 158, 160, 302) of the studs (156). Rotation of the single point adjustment causes each of the protrusions (216) to move within each respective channel forcing the wedge member (202), the studs (156), and the restrictor member (300) to move in a direction that is substantially perpendicular to the longitudinal direction.

    摘要： Apparatus (100, 101, 102) and die cartridge assembly (18, 44, 45, 47) adapted for use with same for producing fibrous material (212). The apparatus (100) comprises a removably attachable die cartridge assembly (18) that adapts to conventional spunmelt equipment. The die cartridge assembly (18) is removably positionable beneath an extrusion body (10) for effecting formation of fibrous material by fibrillation of polymer films. The cartridge assembly (18) includes at least one polymer passage (19) communicating with a molten polymer source (10) for directing molten polymer onto at least one film forming surface (20, 28) defined by the cartridge assembly (18), and also defines at least one gas passage (222, 22, 30) communicating with a gas source (16) for directing pressurized gas (220) against the molten polymer (210) in the form of a film for effecting formation of the fibrous material (212).

    摘要： The present invention relates to an integrated process for the production of polyester tape, comprising the steps of a) preparing feed polyester comprising a polymerisation reaction in one or more reactors in series and measuring the viscosity of the obtained feed polyester, b) feeding the feed polyester obtained from step a) and optional additives to a melt mixing device, mixing said feed polyester and said optional additives so as to form a molten polyester composition and measuring the viscosity of the obtained polyester composition, c) extruding the molten polyester composition through a film extrusion die thereby forming a molten film of said polyester composition, d) preparing a polyester tape from said molten polyester film, said preparing comprising trimming the edges of the film at a stage where said film is below its melting temperature, e) feeding at least a part of the trimmed edges obtained in step d) in-line to the melt mixing device in step b) wherein the amount of trimmed edges and optional further additives fed to the melt mixing device in step b) is controlled on the basis of the measured viscosity of the polyester composition.

    摘要： Eine Sicherheitskupplung (100) für einen Doppelschneckenxtruder, weist wenigstens ein Paar von Kupplungshalbelementen (10, 20) auf, welche jeweils eine Wellenaufnahmebuchse (21) für das Wellenende (202, 301) einer Antriebswelle (201) oder einer Extruderschnecke (301) besitzt und welche über wenigstens zwei Scherelemente (30) miteinander koppelbar sind.
    Die Kupplungshalbelemente (10, 20) besitzen jeweils eine flanschlose, zylindrische Hülle (12, 22), die die Wellenaufnahmebuchse (21) umschließt und in einen Bodenbereich (13, 23) übergeht. An einer Stirnseite, die den Bodenbereich (13, 23) abschließt, ist jeweils wenigstens eine Bohrung (14, 24) je Scherelement (30) vorgesehen. Die Kupplungshalbelemente (10, 20) liegen mit ihren am jeweiligen Ende des Bodenbereichs (13, 23) gelegenen Stirnseiten (15, 25) voreinander und sind über die die Trennebene (T) überbrückenden Scherelemente (30) gekoppelt.
