ABSTRACT:
A device (8) for forming containers (2) produced continuously from a tubular wrapper (3) fed along a substantially vertical direction of advance (A). The device has at least one support carriage (8a) movable along a respective closed path having at least one active segment parallel to the direction of advance (A). The carriage (8a) supports a sealing base (11) able to be associated to a first lateral face (2a) of the tubular wrapper (3) at a sealing region (Z) of the wrapper (3). A contrasting element (14) is removably associated to the support carriage (8a) and movable between a first closed position in which it is approached to the base (11) and abuts against a second lateral face (2b) of the tubular wrapper (3) opposite to the first lateral face (2a) at the sealing region (Z), and a second position in which it is movable away from the base (11).
