APPARATUS FOR FORMING AT LEAST ONE CONTINUOUS STRIP OF CONTAINERS

摘要

A forming apparatus for forming at least one continuous strip of containers comprises a feed line for the indexing along a preset route according to an advancing direction and with a preset advancing step two continuous webs in film material that face each other. The webs pass through a heat-sealing station provided with a separator the end of which is arranged to be inserted between two open longitudinal flaps of the webs. During the phase of heat-sealing of the webs the separator is kept in position to exert downward pressure against said flaps by means of an axial fluid actuator. The invention ensures that at the forming station, that is contiguous with and subsequent to the heat-sealing station the flaps are sufficiently separated to receive the nozzles that blow in the forming fluid.
