A rotor for a rotary press comprising a die plate having die bores and upper punches and lower punches assigned in pairs to the die bores, circulating synchronously with the die plate An upper punch receiver is configured to axially guide the upper punches and a lower punch receiver is configured to axially guide the lower punches. An upper control cam is configured to control the axial movement of the upper punches passing through the upper control cam and a lower control cam is configured to control the axial movement of the lower punches passing through the lower control cam.

A spray head for the cooling lubrication of a lower die and/or an upper die of a forming machine is disclosed. The spray head is able to be introduced between two working strokes into a working chamber between the lower die and the upper die. The spray head has at least two individually controllable nozzles for the cooling lubrication of different places of a die surface of the lower die and/or the upper die. The spray head also has a thermal imaging camera for recording a thermal image of the lower die and/or the upper die. A forming machine has a cooling device comprising an aforementioned spray head.

Method of forming a compact based on the press forming method provides a compact having high density and not having cracking or surface roughness in a product and without compact adhesion to press forming mold wall occurring, including steps: filling raw material powder in a cavity formed by an outer mold and lower punch, or outer mold and lower punch and core rod, pressing and forming raw material powder between an outer punch and lower punch, and extracting the compact obtained out of the outer mold by the lower punch, wherein a lubricating film of a press forming mold lubricant containing oil as main component is formed on at least part of outer mold inner surface, or outer mold inner surface and core rod outer circumferential surface before filling the raw material powder in the cavity, and press forming so that compact density ratio is not less than 93%.

In a method for external lubrication of the press rolls (2 or 2.1) of a roller compaction device (1) by means of a continuous coating of said press rolls (2 or 2.1), a thin layer of a lubricant and/or an anti-adhesive are continuously provided to coat the press rolls (2 or 2.1). This coating preferably contains magnesium stearate or a mixture containing magnesium stearate. To carry out the method, at least one coating device (13, 14, 15 or 13.1, 14.1, 15.1) is arranged in a housing in which the press rolls (2 and 2.1) are arranged, by means of which coating device at least one press roll is provided with a thin coating of a lubricant and/or an anti-adhesive, preferably with magnesium stearate or a mixture containing magnesium stearate. The method is used for the manufacture of dry granules in the pharmaceutical and food industries.

A compression molding machine includes a first spray device configured to spray an external lubricant to at least one of the inner surface of a die bore, the upper end surface of a lower punch, and the lower end surface of an upper punch, and a second spray device configured to spray a coating agent for blocking a strange taste or an odor of a molded product, or the like, to at least one of the inner surface of the die bore, the upper end surface of the lower punch, and the lower end surface of the upper punch.

A rotary tablet press, comprising a lubrication device configured to lubricate at least one of the upper and the lower pressing punches with a lubricant. The lubrication device includes a lubricant reservoir configured to hold a lubricant and a stationary applicator connected to the lubricant reservoir and configured to apply the lubricant to at least one of the upper pressing punches and the lower pressing punches rotating past the stationary applicator. A control apparatus is configured to individually control an amount of lubricant applied by the stationary applicator to the at least one of the upper pressing punches and the lower pressing punches for different upper or lower pressing punches.

A device for pressing material includes a control device, at least one first endless band forming a first presser; and at least one second presser. A pressing zone for pressing material is formed between the first endless band and the second presser and a longitudinal direction parallel to the first endless band is defined in a direction with respect to the pressing zone, from beginning to end of the pressing zone. By at least one pressure-exerting device, a pressing pressure on the at least one first endless band inner surface that is directed away with respect to the pressing zone can be built up in the direction of the pressing zone. The pressure-exerting device is designed so that at least one fluid can be applied onto the at least one first endless band inner surface in the direction of the pressing zone to build up the pressing pressure.
