Abstract: The invention relates to a device for transferring, depositing and positioning films that are used as cores in coating-core tablets, in matrices of tablet presses, said device comprising at least three modules, a. module 1 (11) comprising at least one storage unit that contains the films, and/or at least one supply unit that supplies the films for transfer by a second module, b. module 2 (12) comprising at least one transfer unit, at least one conveyor belt (17) and at least one intake wheel (22), c. module 3 (13) comprising at least one controllable vacuum head (25) which comprises a removal device that removes the films from the carriers (28) of module 2 (12) using a vacuum and deposits them in the matrices of the tablet press (14).

Abstract: The invention relates to a method for inserting inserts (cores) into female molds of a rotary tableting press. The inserts are inserted individually into one female mold each of a rotating rotor of the rotary tableting press by separating the inserts from a nonspecific quantity by means of a feeder mechanism, feeding them to a core distributor and aligning them from there with the female molds in a precisely defined position and delivering the inserts to the female molds in this position.

Abstract: The invention relates to a rotary pelleting machine comprising a driveable die block provided with a defined number of dies distributed over the periphery thereof, bottom rams and top rams which are associated with the dies and rotate about a common rotational axis, synchronously with the die block, along a bottom ram guide and a top ram guide, at least one filler device for filling the dies with a material to be compressed, and a compression device for acting on the rams with a compression force. According to the invention, the filler device (18) comprises at least two independently chargeable filling chambers (24) which can be successively brought into a defined filling position. The invention also relates to a method for producing a multi-layer pellet by means of a rotary pelleting machine.

Abstract: A device for positioning in a mold table of a tabletting machine, in particular a rotary tabletting machine with facon molds that have molding cavities and form a circular cylinder on an outer perimeter. Each facon mold has at least one centering area associated with the molding cavity and for each facon mold, a centering piece is movably mounted on the mold table to engage the centering area of the facon mold. The centering area in cooperation with the centering piece properly positions the facon mold to the upper ram of the tabletting machine.

Abstract: A device for fixing the dies in the die table of a tabletting machine, especially of a rotary tabletting machine, using die holders. To make it possible to rapidly remove the old dies and to rapidly fix the new dies during the replacement of the dies for cleaning the machine, the die holders are arranged between the rotor axis and the pitch circle of the dies, and structure is provided for jointly moving the die holders on the die table.

Abstract: A process for quality control in tablet production by pressing by means of influencing the pressing force, the weight, the hardness, and the height of the tablets by means of a control mechanism. The task of the invention is to develop a process of the type according to this concept, according to which all necessary control mechanisms for maintaining a constant tablet weight, tablet height, and tablet hardness operate in such a way that a rapid control of deviations is assured, and according to which, the limiting values can be optimized automatically, is hereby resolved in that the control system is divided into several influential and essentially parallel running control circuits for the simultaneous control of the pressing force as well as the tablet parameters of weight, height, and hardness.

Abstract: A process for cleaning tabletting, pan-coating and granulating machines, especially rotary tabletting presses, with a treatment chamber including at least the rotor. To ensure the complete removal of the liquid residues from the treatment chamber and from the components left in the treatment chamber, especially of the rotor of a rotary tabletting press using small amounts of cleaning and rinsing liquids, a cleaning agent and a rinsing agent are sprayed within the treatment chamber and then drained off. All openings of the treatment chamber are then closed, and a vacuum of about 0.1 to 0.2 bar (absolute pressure) is generated within the sealed treatment chamber. The vacuum drains the residual liquid from all holes and joints of the rotor and from the treatment chamber.
