Abstract: A press for shaping an absorbent tampon blank into a shaped tampon pledget includes a central cavity arranged and configured to accommodate an absorbent tampon blank having a front portion and a back portion. The main longitudinal axis of the press passes in the middle of the central cavity and a plurality of penetrating dies are arranged radially around the said main longitudinal axis. Each penetrating die has a pressing face on at least a fragment of its side facing the central cavity. The said press comprises at least one cam to actuate the plurality of penetrating dies. Furthermore, the plurality of penetrating dies comprises at least one penetrating die having a pressing face with a first shaped longitudinal profile, and least one penetrating die having a pressing face with a second shaped longitudinal profile.

Abstract: A doming tool for manufacturing absorbent tampon includes a plurality of stations made of devices for shaping a tampon pledget tip, and a hollow mandrel engaging with the stations. The stations are supported by at least one mounting plate.

Abstract: A feed unit, for example for feeding components to smoking article assembly apparatus, has a guide member (14) and a plurality of pushers (21) arranged to push components (2) along a path defined by the guide member (14) for output from the feed unit. The guide member (14) is arranged to separate the components (2) into separate streams (63, 64) according to their orientation. The stream (63) of non-correctly oriented components (2) comprises a channel that is helically rotated to orientate correctly said components (2). Both streams (63, 64) converge downstream said helical section to achieve a single flow of components (2) of similar orientation.

Abstract: A feed unit, for example for feeding components to smoking article assembly apparatus. The feed unit has a rotary device having a supply region (4) and one or more channels (7) adapted to receive components from the supply region (4) such that the components are stacked one on top of another within each channel (7). Each channel (7) has an inlet (5) and an outlet through which components pass for output from the feed unit. One of the inlet (5) and the supply region (4) is configured to reciprocate relative to the other to agitate the components in the supply region (4) so that components pass into the channel (7).

Abstract: A feed unit, for example for feeding components (2) to smoking article assembly apparatus, having a stationary guide member (14) and a dispensing unit configured to dispense components (2) into the stationary guide member (14). The dispensing unit has one or more channels (7) to receive components (2) one on top of the other, and each channel (7) has a control gate (12) to apply suction/gaseous flow to control output of components (2) from the channel (7) for onward conveyance through the stationary guide member (14).

Abstract: A feed unit, for example for feeding components to smoking article assembly apparatus, includes a rotary device having one or more channels (7) adapted to receive components, one on top of another, and one or more pushers (21) associated with each channel. The feed unit also has a track (14) to receive components from outlets of the one or more channels (7) and the rotary device is configured to rotate with respect to the track (14) so that components pass through the channels (7) and are pushed along the track by the pushers (21) for output from the feed unit.
