The invention relates to a feeding carriage for a compressor machine of the type having an upper filling end through which a particulate material which is to be compressed in a mold of the compressor machine is introduced, and a lower discharging end for discharging said particulate material towards said mold. At least some of the elements forming said feeding carriage can move with respect to one another, which thereby allows modifying the geometry of at least one of said lower discharging end, said upper filling end and an intermediate portion of the supply carriage located between both ends. The invention also relates to the use of such a feeding carriage comprising the initial steps of determining optimum carriage geometry for a particulate material which is to be compressed and applying said optimum carriage geometry to the feeding carriage.

Provided is an imprint apparatus that includes a supplying device configured to supply an imprint material to an imprint region on a substrate; a driving device configured to perform driving for bringing a mold into contact with the imprint material supplied to the imprint region; and a sealing device configured to seal the imprint region by forming a flow of gas, wherein the supplying device includes a member having a surface facing the substrate, an inlet port through which the gas flows into the member and an outlet port through which the gas flows out of the member are formed in the surface, and a flow path for connecting the inlet port with the outlet port is formed in the member.

A microporous insulation material mixture is blended and the blended mixture is spread across a lower conveyor belt which is trained over rollers. To aid the spreading of the mixture a spreading device is used. The mixture is delivered by the conveyor to a pressing system which in this case comprises an upper conveyor belt. The pressing system also comprises a nipping means provided in this case by a plurality of upper and lower nipping rollers. The gaps between the individual rollers are adjustable. An upper fleece liner is led from a delivery roller to lie between the upper conveyor belt and the insulation mixture and a lower fleece liner is fed from a delivery roller to lie between the insulation mixture and the lower conveyor belt. The fleece liners may be used to encase the core prior to enclosing in an envelope and applying a vacuum.

In methods and apparatuses for producing auxetic foam from conventional foam, conventional foam is compressed into a mold before thermal, chemical or thermo-chemical treatment processes are performed. A segmented mold is accommodated in a compressing apparatus. After compressing the foam between the mold segments, the mold is fastened shut and removed from the compressing apparatus. The forces applied to any given volume of foam and the amounts by which the foam is compressed while being processed are controlled to impart desired mechanical properties to the produced foam. Poisson's ratio and density of discrete portions of finished foam shapes are reliably predicted and controlled to achieve uniform and non-uniform mechanical properties within a single continuous quantity of foam.

A system for continuously processing pulverulent products includes at least two system inlets for pulverulent products. A mixer is provided that continuously mixes the pulverulent products received at a mixer inlet into a product mixture that is dispensed at a mixer outlet. A production machine having a filling apparatus continuously processes the product mixture from the mixer outlet into end products dispensed at the machine outlet. A conveyor apparatus conveys the product mixture from the mixer outlet to the machine inlet. The conveyor apparatus includes a first fill level sensor that measures a product mixture fill level in the filling apparatus of the production machine and a second fill level measures a product mixture fill level in a conveyor reservoir. A control apparatus receives measurement data from the first fill level sensor and the second fill level sensor and controls at least one production parameter based on the measurement data.

A method and system for feeding a lubricating or releasing agent from a dosing station to one or more pressing tools arranged in a pressing chamber of a tablet press. The tablet press is configured with a feed pipe for feeding the lubricating or release agent from the dosing station to the one or more pressing tools of a pressing chamber of the tablet press and the feed pipe is configured with a shut-off valve disposed in-line with the feed pip for controlling the flow of the lubricating or release agent to the pressing chamber. The method comprises the steps of: producing a negative pressure with respect to the surroundings of the pressing chamber of the tablet press, measuring a pressure in one of the feed pipe and the pressing chamber, and issuing a signal indicative of the measured pressure and issuing an enable signal to open a valve in response to the pressure signal.

A pellet press machine, comprises a die block assembly for receiving powder to be compacted, and a press assembly for compacting the powder, the die block assembly laterally movable along a linear horizontal axis between the filling location at which an array of dies are filled with the powder to be pressed at the pressing location in which the powder in dies is pressed to form pellets. The filling assembly includes an auger driving by a motor to force the powder directly into dies. The auger further has a sharp edge sits right above the dies to force the powder directly into dies and the sharp edge scrapes the top surface of the dies so as to allow the high degree accuracy of filling dose for each die. With this filling assembly, the pellet press machine can product high density and small diameter pellet with high density and sticky density powder.

A device produces pellets from pressed material, including a feeding apparatus for receiving pressed material, which is arranged in the region of a feeder screw, a pre-pressing chamber which can be fed by the feeder screw, a closable main pressing chamber having a main ram movable for compacting the content of the main pressing chamber, and an ejecting apparatus having a closing slide, and a cutting device for cutting the pressed material during or after entering the pre-pressing chamber, the device being designed to cut the pressed material supplied to the pre-pressing chamber via the feeder screw so as to provide cut pressed material in the pre-pressing chamber and/or main pressing chamber for the purpose of compaction.

Provided is an imprint apparatus that includes a supplying device configured to supply an imprint material to an imprint region on a substrate; a driving device configured to perform driving for bringing a mold into contact with the imprint material supplied to the imprint region; and a sealing device configured to seal the imprint region by forming a flow of gas, wherein the supplying device includes a member having a surface facing the substrate, an inlet port through which the gas flows into the member and an outlet port through which the gas flows out of the member are formed in the surface, and a flow path for connecting the inlet port with the outlet port is formed in the member.

Embodiments are directed to a compression molding apparatus. The compression molding apparatus may include a female mold, a heated male mold, and a cooled male mold. The female mold may carry ultra-high-molecular-weight polyethylene (UHMW) material. The heated male mold may compress the UHMW material in the female mold during a first time period. The cooled male mold may compress the UHMW material in the female mold during a second time period.
