A rotor for a rotary press comprises a die plate, upper punch seats, and lower punch seats configured to be rotationally driven by a rotary drive. An annular discharge channel is configured to be in a fixed position with respect to the die plate and further configured to collect product residue from at least one of the die plate and the lower punch seat. The discharge channel additionally comprises a removal region where the product residue is configured to be removed from the annular discharge channel A catch element is configured to rotate in sync with the die plate and is guided within the annular discharge channel to convey the product residue collected in the annular discharge channel to the removal region.

The rotary tablet press comprises a machine base assembly and detachable module. Granulation is fed into the module from the hopper and travels into the feeder chamber. The base assembly comprises motorized pressure roll assemblies and a turret drive assembly. The detachable module comprises a module base, turret base, turret, cam body, cams, feeder, tablet discharge chute, hopper, upper enclosure, and guard doors. The rotary turret comprises upper punches, dies, and lower punches. As the turret rotates, the dies move underneath the feeder chamber. The rotary feeder paddles move the granulation and assist with feeding powder to the dies. Punches travel along cam tracks as the turret rotates and compresses the powder into a tablet when the punches contact the pressure rolls. An ejection cam pushes the lower punch in the upward direction and a take-off bar mounted just above the die table directs the tablet into a discharge chute. The detachable module is sealed by incorporating an upper enclosure.

A method for sampling both layers of a bi-layer tablet, comprising forming a first layer of a first pharmaceutical powder of the bi-layer tablet in a tablet press machine, performing weight compensation for forming a second layer of a second pharmaceutical powder of the bi-layer tablet based at least on the formed first layer, performing height compensation for forming the second layer of the second pharmaceutical powder of the bi-layer tablet based at least on the formed first layer, and forming the second layer of the bi-layer tablet based on the performed height compensation and weight compensation, in the tablet press machine, for individually sampling both the first and second layers of the bi-layer tablet.

The invention relates to a rotary press having height-staggered ram tips for carrying out at least two pressing operations, which preferably build on one another. Furthermore, the invention relates particularly to rotary presses and methods for producing multi-layer and coating-core tablets and for pressing tablets into cups during a rotation.

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.

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.

The invention relates to a device (10) for producing a compression moulded body (11), having at least one first moulded layer, wherein the device has an upper ram arrangement (12) and a lower ram arrangement (13), with in each case at least one ram unit (15, 16), and a mould (14), wherein the ram unit has at least one ram tool (17), wherein the ram tools are configured such that they can be displaced axially with respect to one another in a die (19) of the mould, in such a way that moulding segments can be configured in the mould by means of the ram tools, wherein the device has a filling device (27), wherein the die can be filled with moulding material by means of the filling device, wherein the upper ram arrangement and the lower ram arrangement in each case have a multiplicity of circularly annually arranged ram units, wherein the mould is configured as a die plate (18) and, together with the ram units, configured as a rotor which is configured such that it can be rotated about an axis, wherein the device has a feed device (30), wherein a film (31) can be fed to the rotor by means of the feed device, such that it lies between a ram tool and a die which is configured in the die plate, wherein a layer can be configured on the first moulding layer by means of the film.

The present invention pertains to a method of producing a compressed nicotine tablet comprising nicotine. The method comprising the steps of adding a first powdered portion of tablet base material into a punch die, pressing said first tablet base material by means of an upper and a lower punch to obtain a first pressed material, inserting an object at the upper face of the first pressed material and fixing the object in a central cavity of the first pressed material, adding a second powdered portion of tablet base material into the punch die, and pressing said first and second tablet base material around the object to enclose the object from the surface of the tablet. The object is based on a material different from the first and/or the second powdered portion of tablet base material.
