Beverage pad and apparatus for making beverage pads

A puck forming device for use in an apparatus for making beverage pads, each pad having an amount of extractable or soluble beverage preparation product as a compacted puck enclosed between two sheets of filtering material, wherein the pads are useable in a beverage preparation machine for preparing a beverage by supplying the pad in the machine with an aqueous fluid under pressure to extract or solubilize the beverage preparation product, the puck forming device arranged to compact the dose of beverage preparation product in the compacted puck and to deliver the compacted puck to a packaging device of the apparatus for enclosing the compacted puck between two sheets of filtering material to form the beverage pad, wherein the puck forming device comprises:

• a cylindrical rotating drum with an outer side surface having recesses for receiving in each recess the dose of extractable or soluble beverage preparation product, a bottom wall of each recess formed by a respective movable piston arranged to move with respect to the outer side surface of the drum to vary a height of the recess in relation to an angular position of the recess on the circular circumference of the drum;
• and
• a compression body adjacent to the rotating drum arranged to provide a counter surface for the dose of extractable or soluble beverage preparation product in the recess in the rotating drum positioned at an angular position opposite the counter surface to be compressed against, against which counter surface the dose of extractable or soluble beverage preparation product is compressible by the respective piston of the recess to form the compacted puck, wherein the compression body comprises drive means arranged to drive the counter surface moving along a circumferential part of the outer side surface of the rotating drum with a velocity corresponding to a velocity of the outer side surface of the rotating drum,
• wherein the compression body comprises a sequence of links, wherein at least one link of the sequence of links provides the counter surface, and
• wherein the links in the sequence of links are coupled to each other in a closed loop to form a continuous rotating chain.
