Abstract

Il trovato è riferito ad un procedimento per produrre strutture a rete in materia plastica che comprende una prima fase di estrusione di una struttura tubolare di filamenti longitudinali continui in materia plastica e da una successiva fase che consiste nel sovrapporre filamenti trasversali distanziati al fine di definire un disegno quadrato o rettangolare di fori regolari.Il trovato si riferisce anche ad un apparato per attuare il procedimento comprendente una testa di estrusione con corpo sostanzialmente cilindrico all'interno del quale è definita una camera per il passaggio della materia plastica proveniente da un macchinario estrusore verso un'uscita inferiore.L'apparato si caratterizza per il fatto che detta uscita inferiore è definita tra un'apertura, posizionata in corrispondenza di una porzione inferiore alla fine di detta camera per il passaggio della materia plastica di detta testa, e di una piastra circolare che si affaccia verso detta porzione inferiore.Almeno una delle aperture e della piastra circolare sono provviste di una scanalatura con una pluralità di fessure passanti.Almeno una delle porzioni inferiori e della piastra circolare è collegata ad un mezzo di movimento alternativo per andare a portarsi in battuta e separarsi rispettivamente l'una dall'altra.The invention relates to a process for producing plastic mesh structures which includes a first extrusion step of a tubular structure of continuous longitudinal plastic filaments and a subsequent step which consists of superimposing spaced transverse filaments in order to define a square or rectangular design of regular holes The invention also refers to an apparatus for carrying out the process comprising an extrusion head with a substantially cylindrical body inside which a chamber is defined for the passage of the plastic material coming from an extruder machinery towards a lower outlet.The apparatus is characterized by the fact that said lower outlet is defined between an opening, positioned at a lower portion at the end of said chamber for the passage of the plastic material of said head, and of a plate circular that faces towards said lower portion openings and of the circular plate are provided with a groove with a plurality of through slots. At least one of the lower portions and of the circular plate is connected to an alternative means of movement to go to stop and separate respectively from each other.
