A forming station for producing a packaging trough by thermoforming at least an area of a film web positioned between a forming tool upper part and a forming tool lower part of the forming station. A male die part of the forming tool upper part may be moved in a vertical direction and inserted into a forming space of a female die part of the forming tool lower part. The packaging trough is produced by deforming the film web between the male die part and an inner wall of the forming space of the female die part. In an inserted condition of the male die part within the female die art, a push-in unit is extended from the male die part towards the inner wall of the forming space at an angular orientation relative to the vertical direction.

The thermoforming assembly includes feeding devices for moving a continuous strip-shaped semi-finished product along a forwarding path, along which a forming mould is arranged defining a forming cavity delimited by a base wall, a first pair of respectively opposed side walls, and a second pair of respectively opposed side walls. Heating devices operate on the strip-shaped semi-finished product near the forming mould, and forming devices are operatively associated with the forming mould and configured to conform the strip-shaped semi-finished product against the base wall and the side walls defining the forming cavity. At least one of the side walls belonging to the second pair is a movable wall, positionable towards and away from the other side wall belonging to the second pair, to vary the dimension of the forming cavity.

A packaging machine is for forming a product cavity in a web including a forming die box defining a recess into which the product cavity is formed. An insert is axially movable in the recess to thereby vary a depth of the recess. A variable depth mechanism selectively moves the insert to vary the depth of the recess. The packaging machine includes a latching mechanism that moves the forming die box into and between a first position in which the forming die box is spaced apart from the die box base and a second position in which the forming die box is supported by the die box base.
