The present invention is related to a method for testing multilayer tablets in a multiple rotary press, in which die holes of a circulating die plate are successively filled with tablet material of different layers in succeeding filling devices, and the tablet material is compressed one layer after the foregoing layer into pressed articles having n layers by means of synchronously circulating compression punches, and the pressed articles are subsequently ejected in an unloading station and taken out, in which in a testing procedure, pressed articles with m layers are taken out after the compression in a respective unloading station and are conveyed to a testing station, wherein applies 1&#x3c;=m&#x3c;=n, wherein before taking out the pressed articles, at least the m-th layer is compressed more strongly than during the normal manufacture of the multilayer tablets, wherein applies m&#x3c;n. According to the present invention it is provided that only pressed articles of die holes are supplied to the testing station, which had been completely filled with the tablet material of the m-th layer already before the initiation of the testing procedure.

Method for testing multilayer tablets

A pressing station in a rotary press having a bearing component for a compression roll that can be adjusted vertically in height along a guide attached to the frame of the rotary press, a first adjustment drive fastened to the frame, which is coupled via an adjustment drive to the bearing component for height adjustment of the bearing component, wherein a shaft or axle for the compression roll or the bearing component or a part of these is coupled to a second adjustment drive in such a way that the compression roll can be adjusted in its height independently from the first adjustment drive.

Pressing station in a rotary press

A method for operating a rotary press, comprising a rotor rotatably driven about a vertical axis that has a die-plate and upper and lower rams which, while being guided vertically in guides of the rotor, interact with holes of dies in the die-plate wherein at least one compression station is provided and has an upper and a lower pressing roller past which the presser rams run along and by which they are moved towards the die-bore for the purpose of compacting the material in the die-hole, wherein the upper and lower rams are lifted subsequent to the compression procedure, causing the lower ram to eject a compact from the die and the compact to be stripped by a stripper in the direction of a discharge chute, characterized in that while an compact ejection procedure is under way the upper ram stands upright on top of the compact and is lifted therewith and the stripper seizes the compact laterally while the upper ram is still standing upright on top of the compact.

Method for operating a rotary press and concentrically running press

Rotary press with a rotor, rotatingly drivable around a vertical axis of rotation, which has a die plate with die bores and upper and lower punches guided in guidings, radial cams for the upper and lower punches, at least one compression station with upper and lower pressing roller, at least one filling equipment and at least one stripping device for pressed articles which are ejected from the die bores, characterized in that the rotor has an annular plane situated radially outside of the graduated circle for the die bores, which is concentric to the axis of rotation and is lowered with respect to the upper side of the die plate about a predetermined degree, first deflection portion direct the ejected pressed articles to the annular plane and second deflection portion direct the pressed articles from the annular plane towards the outside.

Rotary press

A sealing strip for a housing of a pelletizing machine has a one-piece sealing body with a central web with an upper side having two upper edges and a lower side having two lower edges, two sealing lips extending from the upper edges of the upper side of the central web at an angle relative to one another, and a clamping strip extending from a center of the lower side of the central web and provided with lateral webs.

Sealing strip for housing of pelletizing machine

A rotary pelletizing machine has a rotatable matrix disc, a plurality of vertically adjustable pressing rollers which control position of the upper and lower plungers, a drive for a height adjustment of the rollers, a housing accommodating the drive, and a bearing block supporting the pressing roller and releasably connected with the housing.

Pelletizing machine

A rotary pelletizing machine comprises a rotatable matrix disc, a plurality of upper plungers and lower plungers guided in the matrix disc, and an element for holding the lower plungers from falling out during a dismounting of the matrix disc, the holding element including a braking ring arranged in the matrix disc and pressing radially against the lower plungers so as to hold the lower plungers from falling out.

Rotary pelletizing machine with matrix disc having copper and lower

A rotary pelleting machine comprises a housing, a drive shaft, a matrix disc connected with the drive shaft and guiding upper plungers and lower plungers, a unit for controlling position of the plungers during rotation of the matrix disc. The unit includes a cam ring provided for controlling the upper plungers. The cam ring is supported rotatably relative to the housing and the drive shaft. Also a unit for measuring a torque of the cam disc is provided.
