摘要

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 ( 8 a) movable along a respective closed path having at least one active segment parallel to the direction of advance (A). The carriage ( 8 a) supports a sealing base ( 11 ) able to be associated to a first lateral face ( 2 a) 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 ( 8 a) and movable between a first closed position in which it is approached to the base ( 11 ) and abuts against a second lateral face ( 2 b) of the tubular wrapper ( 3 ) opposite to the first lateral face ( 2 a) at the sealing region (Z), and a second position in which it is movable away from the base ( 11 ).
