The invention relates to a method for the mass decoration of ceramic products, comprising the following steps: spreading, superposed on one another, a layer (L) of granular or powder material and a decorative layer (3) on a support surface (2); transferring the layer (L) from the support surface (2) to an accumulation belt (T1), contiguous and aligned to the support surface (2), which is located at a lower height than the support surface (2), wherein the accumulation belt (T1) is mobile in advancement at a speed that is different from the advancement speed of the support surface (2), so that a variation in the thickness and longitudinal extension of the layer (L) is produced; pressing the layer (L) and the decorative layer (3).

A removal apparatus for removing pellets from a die plate of a rotary press comprises a housing and a first channel positioned on the housing and configured to receive pellets removed from the die plate. A guide element is arranged on the housing and positioned over the die plate. The guide element is configured to guide pellets produced in the rotary press from the die plate into the first channel. The guide element and the first channel are moveably mounted on the housing. A plurality of mechanical positioning elements are configured to be alternatively inserted into the housing and cooperate with the guide element and the first channel to movably position the guide element and the first channel relative to the housing. Each of the mechanical positioning elements defines a different position of one of the guide element and the first channel relative to the housing.

A pressing arrangement (100) is disclosed. The pressing arrangement (100) comprises a pressure vessel (2) comprising a pressure cylinder (1). a top end closure (3) and a bottom end closure (9), a furnace chamber (18) for heating a pressure medium, a plurality of guiding passages (10, 11, 13), a load compartment (19) configured for holding at least one article to be treated, and at least one flow generator (30, 32) for circulating pressure medium within the pressure vessel. The pressing arrangement further comprises a heat exchanging element (170) arranged in the top end closure or in the bottom end closure. The heat exchanging element comprises at least one passage for allowing a flow of pressure medium through the heat exchanging element, and at least one circuit for allowing a circulation of cooling medium within the at least one circuit for a cooling of the pressure medium.

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 device for capacitively measuring a powder fill level in a filling apparatus for a rotary press where the fill apparatus comprises a filling pipe. The device comprises a first measuring electrode positioned on the filling pipe and a reference electrode. A first electrical capacitor is configured to be formed by the reference electrode and the first measuring electrode, wherein an electrical field is configured to be formed between the first measuring electrode and the reference electrode. The first measuring electrode is covered by an electrically conductive protective shielding on a side facing away from the filling pipe and the electrically conductive protective shielding is at a ground potential.

A rotary press comprising at least one pressing station having each of a vertically-adjustable upper and lower pressure roller, which are mounted by axes in the at least one pressing station. Cam-guided upper punches having punch heads are fed to the upper pressure roller by a control cam and a pull-up cam raises the upper punches to a highest point above a filling device. A vertically-adjustable safety cam is designed to be vertically adjustable in relation to the upper pressure roller. The rotary press may comprise a preliminary pressure cam, which is integrated in a guide block.

The invention relates to a method of controlling a ceramic and/or metal powder press (1) for pressing a compressible material (6), wherein at least one electromotive drive (15, 16; 20, 21), which adjusts at least one punch (5; 4) along a pressing direction, is controlled in such a manner that the drive (15, 16; 20, 21) moves the punch (5; 4) along a setpoint positioning path (as1) and the drive is readjusted if it deviates from the setpoint positioning path (as1), wherein a measured force (F11, F12) acting on the compressible material (6), the punch (4) or its supporting components (17-19), is used as at least one control variable for readjustment. The invention also relates to a ceramic and/or metal powder press (1) configured to carry out the method.

A filling unit for filling cavities in a tablet press with a feedstock to be pressed, particularly a powder, having a filling assembly including a fill chamber. The fill chamber is arranged in the installed condition between a die table containing the cavities and a punch support including at least one punch. The fill chamber has at least one inlet opening for filling the fill chamber with raw material and at least one outlet opening for filling the cavities of the tablet press with feedstock to be pressed. The filling chamber has at least one mixer for mixing the raw materials of the feedstock to be pressed arranged at least partially in the fill chamber and at least one delivery unit for filling the cavities of the tablet press with feedstock to be pressed.

The invention relates to a method for calibrating, in particular, sintered pressed parts, wherein a calibration procedure of each individual pressed part is controlled depending on at least one specific pressed part parameter of the respective pressed part measured before calibration and/or depending on at least one production parameter of a preceding pressing and/or sintering step of the respective pressed part.
