<p>Retrofitting apparatus, for splitting, applying and pre-incise, at least one continuous strip supplied from a single reel of adhesive tape (5), on at least one side of an envelope of plastic material, to allow the tear opening of at least one side of said envelope, intended for packaging of plants and flowers, produced and extruded in a continuous and automated manner by a pre-existing and conventional machine, in such a way that, the retrofitting of said apparatus which applies the said strip, brings an improvement of the mechanical resistance to stresses, of said envelope destined to subsequent packaging of plants and flowers; which consists of a support structure (1), a motorized reel (2) of adhesive tape (5) that is dispensed and divided into at least two semi half (5a, 5b), by a cutter (9), with speed of unwinding proportional to the tension of said tape (5) that, is made to adhere and incised by blades of pre-incision, on the said envelopes, in continuous manner.</p> |
