An apparatus and process for the delivery of material to rolls of a laminator is disclosed.

The invention relates to a process for the production of thermoplastic moulding compounds, in particular for the production of acrylonitrile-butadiene-styrene (ABS), wherein at least a first reagent (11) and a second reagent (12) of the thermoplastic moulding compounds are fed to a loop conduit (29) which comprises a static mixer (36), wherein the reagents (11, 12) are pressed in loops through the loop conduit (29) and passing the static mixer (36), whereby the reagents (11, 12) are dispersed to form a dispersion (15) in the static mixer (36). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.

A three-dimensional (3D) printing system and method for printing with the 3D system. The 3D system includes a pneumatic dispense gun for mixing a thermoset resin and catalyst and dispensing a catalyzed resin to a rotary dispense valve for application of the catalyzed resin to a substrate on a movable table. The dispense gun contains a catalyst injection unit and a mixer for mixing the catalyst with the thermoset resin. The mixer is downstream of the catalyst injection unit and the catalyst injection unit includes a catalyst injector and a distribution ring surrounding the catalyst injector. One or more first pumps are provided for pumping the thermoset resin from a storage container to the pneumatic dispense gun. A second pump is provided for pumping the catalyst from a storage container to the dispense gun.

A mixing apparatus includes a mixer configured to mix a material including a rubber or a resin in the presence of a working fluid that is in a supercritical state or a subcritical state. The mixer includes a chamber that forms a flow passage for the working fluid and the material, and a mixing blade disposed in the chamber and fixed to the chamber.

A fully impregnated fiber-reinforced thermoplastic granule includes a fiber core impregnated with a thermoplastic resin and coated with the resin and subsequently polymerized to form a thermoplastic. The granule is formed in a continuous process including a continuous fiber strand being coated and impregnated with a thermoplastic resin, curing the thermoplastic resin, and cutting the fiber and thermoplastic into granules of a desired length. The continuous process results in a uniform, fully impregnated fiber core in the granule which results in a longer reinforcing fiber for added strength in subsequently produced products formed from the granules.

The application relates to a process for continuously producing aqueous polyurethane dispersions, which is characterized by the use of micro structured mixing elements and addition of water twice during the dispersion step. The energy input in the mixing of the dispersion is low. In addition, the application describes an apparatus suitable for execution of the aforementioned process.

A device for reducing the microbiological contaminants of container products made predominantly of plastics materials feeds a plastics granulate to an extruder assembly (19) that melts the granulate. The granulate is subsequently supplied to a form-fill-seal machine for producing a container product. A guide assembly (35) guides the plasticated plastic material from the extruder assembly (19) to the machine. At least one guide assembly (35) has at least one flow or channel guide (41) for the melted plastics material, so that microbiological contaminants are guided predominantly into the interior of the wall of the polymeric tube that interior is enclosed by regions of the plastic material that are less contaminated.

A method of manufacturing a plurality of colors of bulked continuous carpet filament from a single multi-screw extruder which, in various embodiments, comprises: (A) passing PET through an extruder that melts the PET and purifies the resulting PET polymer melt; (B) splitting the extruded polymer melt into a plurality of melt streams and adding a colorant to each of the plurality of melt streams; (C) using one or more static mixers (e.g., thirty six static mixers) to substantially uniformly mix (e.g., homogeneously mix) each of the plurality of melt streams with its respective added colorant; and (D) feed each of the uniformly mixed and colored plurality of melt streams into a respective spinning machines that turns the polymer into filament for use in manufacturing carpet, rugs, and other products.

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.
