A connecting device for connecting a screw machine to a gear mechanism comprises a housing which in regions delimits an interior. The interior serves for the arrangement of at least one shaft connection between at least one gear shaft and at least one screw shaft. The connecting device comprises at least one cleaning element for cleaning contaminants from the interior. The connecting device allows simple, efficient and reliable cleaning of contaminants from the interior.

A spinneret assembly for spinning polymeric fibers, including: (a) a cap provided with an inlet port and a flared lower surface that flares outwardly from the inlet port in the direction of flow; (b) a spinneret having numerous spinning flow channels through its thickness; (c) a filter freely resting on the spinneret; and (d) a flow guide with a tapered geometry mounted in a cavity defined by the cap and the spinneret. The flow guide has an apex facing the inlet port, a base facing the filter, and one or more side surfaces tapering up to the apex. A diverging flow passage is defined by the tapering side surface(s) of the flow guide and the cap's flared lower surface. The base of the flow guide is spaced apart from an upper surface of the spinneret, creating a space that is in fluid communication with the divergent flow passage.

The present invention provides a process for the viable production of lyocell cellulose continuous filament yarns.

A self-cleaning dosing apparatus includes a material hopper for containing pellets of material, a feed screw, a first material outlet through which pellets of material fall by gravity onto a first end of the feed screw for the feeding of pellets to a process machine. A second material outlet is located beneath the first end of the feed screw, with a slide gate blocking the second material outlet. A pneumatic piston is provided for pulling the slide gate to unblock the second material outlet, and a Venturi pump is located under the second material outlet for pulling pellets through the second material outlet when the slide gate is opened.

The invention relates to a melt filter (1) for filtering plastic melts, comprising a screen rotor (3) which is arranged such that it can be rotationally driven between two housing plates (2) and which has recesses (5) along a circular path (4) for receiving exchangeable filter elements (6), and comprising a melt channel (7) which penetrates the housing plates (2) in the region of the circular path (4) and is associated with the screen rotor (3). In order to create advantageous conditions, it is proposed that the screen rotor (3) comprises two axially spaced rotor cheeks (9) which are provided opposite one another with filter elements (6) through which the plastic melt can flow and towards which the melt channels (7) of the two housing plates (2) open out, wherein at least one collecting chamber (10) for plastic melt filtered by the filter elements (6) is provided in the screen rotor (3) between opposing filter elements (6), and wherein a flow channel (11) opening out of the screen rotor (2) in the region of the rotor axis (8) is provided for discharging filtered plastic melt from the collecting chamber (10).

An encapsulant compound apparatus, includes a mechanical operator, and an insert disposed on a surface of the mechanical operator. The insert operates to capture foreign material in the encapsulant compound.

The present invention relates to a method for the step-by-step guidance of a machine operator of an extrusion device for a film machine when changing from an application formula to a subsequent formula, comprising the following steps: identifying a formula change request, displaying the formula change request for the machine operator, displaying at least one concluding step to be performed for the application formula, identifying a confirmation of the machine operator for the at least one concluding step, displaying at least one preparatory step to be performed for the subsequent formula, identifying a confirmation of the machine operator for the at least one preparatory step, and concluding the change from the application formula to the subsequent formula.

An extrusion device that produces plastic film includes at least two feed units that feed feedstock for an extruder, wherein, in each feed unit an automatic cleaning device is arranged for a removal of feedstock from the feed unit when changing material in the extrusion device.

An on-line automatic cleaning apparatus of slit extrusion type coating die for lithium battery and a method associated therewith are provided. The cleaning apparatus includes: a die lip, a coating steel roller, and a cleaning mechanism disposed therebetween. The cleaning mechanism includes a cleaning chamber which includes elongated sealing strips and a flow-guiding arc groove. Front and rear ends of the cleaning chamber are connected to an inlet sealing plate and an outlet sealing plate respectively. The flow-guiding arc groove is in contact with and presses upper and lower sloped surfaces of the die lip through the elongated sealing strips to seal and thereby define a closed cleaning tunnel. The inlet and outlet sealing plates are in contact with and press two ends of the closed cleaning tunnel respectively for circumferential sealing. An inlet and an outlet are connected to pipes having solenoid valves installed thereon.

In particular embodiments, a process for producing bulked continuous carpet filament from recycled polymer utilizes two vacuum pumps (140A, 140B) in combination with a single extruder (100). In various embodiments, the dual vacuum arrangement (e.g., at least two vacuum pumps (140A, 140B)) operably coupled to the single extruder (e.g., MRS extruder (100)) may be configured to remove one or more impurities from recycled polymer as the recycled polymer passes through the extruder.
