An extrusion die (12) has an internal deckle system comprising, in a downstream order, an inner deckle rod, where a front end (36) of the deckle rod facing a passageway (14) has a pointed shape and is chamfered. - An extrusion die has an internal deckle system and comprising a flow passageway extending to an exit slot (24), the passageway comprising, in a downstream order, a supply channel (16), a transverse distribution manifold (18) and a channel portion, the internal deckle system comprising, in a downstream order, an upper deckle component (30, 30'), a lower deckle component (32, 32'), and an inner deckle rod, each of which deckle components is adjustably arranged to change the width of the passageway, where a front end of the deckle rod facing the passageway has a pointed shape and is chamfered. |
