The present invention provides a nanofiber manufacturing method and a nanofiber manufacturing device. A solution 25 in which a polymer is dissolved in a solvent is supplied from a distal end of a nozzle 16 to form a Taylor cone 44 at a distal end opening 16b. By applying a voltage between the solution 25 and a collector 50 using a power supply portion 62, an electrospinning jet 45 is sprayed from the Taylor cone 44 to the collector 50. At the start or stop of electrospinning, a blocking member 48 is inserted into a spraying area 42 of the electrospinning jet 45 such that an unstable electrospinning jet or unstable nanofibers are received. A product is not manufactured from an unstable electrospinning jet formed at the start or stop of electrospinning, and the manufacturing of a defective product is prevented.

A method for polymerizing a High Internal Phase Emulsion foam including exposing a High Internal Phase Emulsion foam comprising a photoinitiator to an Ultraviolet light source, and partially polymerizing the top surface of the emulsion.

A single screw extruder (E) for the extrusion of food or feed, comprising in the direction of flow of a product to be extruded: i) a processing section (8); ii) a bypass outlet (B); iii) a valve plate (V); iv) a die plate (D); and iv) a cutter (6). The flow of product can be directed through the valve plate, under normal operating conditions of the extruder (E), and through the bypass outlet (B), during start-up of the extruder (E) or for maintenance purposes, downstream of the valve plate (V). The valve plate (V) is arranged on or in a mounting plate (M). The cutter (6) and the mounting plate (M) are provided with interacting guiding mechanism that prevent rotation of the cutter (6), vis-?-vis the mounting plate (M); and the cutter (6) and the mounting plate (M) are mechanically fastened to each other with rotational locking mechanism.

An interchangeable unit adapted to couple to a computer numerical control (CNC) machine is disclosed comprising a holder that couples to a spindle of the CNC machine, a controller, wherein said controller is configured to receive the rotational speed of the spindle as an input, and a material processing unit, wherein said material processing unit executes a first function in response to a first rotational speed range of the spindle and executes a second function in response to a second rotational speed range of the spindle.

In a kneading extrusion apparatus according to an embodiment, when an extruder is started in order to manufacture a resin compound, an amount of a resin raw material to be supplied is increased with an increase in a rotation speed of a screw of the extruder based on a predetermined starting-time supply pattern for the resin raw material, and a supply of the filler is started after the supplying of the resin raw material is started and an amount of the filler to be supplied is increased with the increase in the rotation speed of the screw based on a predetermined starting-time supply pattern for a filler.

A mouthpiece (10) for extruding a molding compound into a formed body which has internal channels, comprises: a mouthpiece frame (14) with a frame opening (16); a first core retaining plate (22) which is fastened in the area of an upstream end of the frame opening (16) when viewed in the flow direction (15) of the molding compound; and a plurality of longitudinal cores (28) which are axially and laterally held by an upstream end section (26) on the first core retaining plate (22). It is proposed that, furthermore, it comprises a second core retaining plate (36) which is loosely arranged downstream of the first core retaining plate (22) relative to the mouthpiece frame (14) in the flow direction (15), and in which the areas (32) of the cores (28) farther from the upstream end section (26) are arranged to be radially fixed but axially loose.

A melt processing plant including a melt charger for charging a processing head, in particular a pelletizing head, with melt, is provided. Upstream of the processing head a diverter valve for discharging the melt during a starting and/or retooling phase is associated with the melt charger, and a portioning device for portioning the discharged melt into melt portions is associated to the diverter valve. A cooling device for cooling the melt portions to at least partly solidified chunks of material is also provided, the cooling device including a cooling bath having an associated belt conveyor with a first collecting belt portion inclined at an acute angle to the horizontal and extending through the level of the cooling bath for collecting chunks of solidified material.

A method for producing a biaxially oriented tube from thermoplastic material, wherein a tube in preform condition is extruded from thermoplastic material and is subjected to a temperature conditioning. Use is made of an expansion device and of a drawing device which is arranged downstream of the expansion device. The expansion device includes a non-deformable expansion part and a run-on part located upstream of the expansion part and having an upstream sealing member. The expansion device further includes a first gas discharge duct having one or more first inlet ports in the exterior surface of the expansion device, a first inlet port being open or closed or partly closed dependent on whether or not the first inlet port is covered and closed, or partly closed, by the tube.

A method and device for producing metal wire by sheathing a wire with an elastomer compound coming from an extruder is described herein. The aspects disclosed herein may include a feed canal for feeding a sheathing die, through which the wire is made to pass at a pre-established nominal speed. Various temperatures are controlled during the method based on a variety of parameters such as the measured speed at which the wire is moving is other than the nominal speed.
