Abstract

L'invenzione riguarda una combinazione di estrusore-calandra costituita da un estrusore e da una calandra inserita a valle, collegata rigidamente alla testa di iniezione dell'estrusore. Il compito dell'invenzione è quello di fornire una forma strutturale di una combinazione di estrusore-calandra che si distingua per un ingombro strutturale ridotto e in cui, già dopo brevi percorsi quasi uguali, i nastri estrusi possano essere riuniti per cui il prodotto presenta i vantaggi della tecnologia "Roller Head" o a testa a rulli, senza presentare tensioni o sollecitazioni interne. L'invenzione consiste nel fatto che nel supporto della calandra due coppie di rulli sono posizionate l'una al di sopra dell'altra, che ad ogni coppia di rulli o cilindri è associata una testa speciale di iniezione, in cui una testa di iniezione è disposta al di sopra dell'altra, e che ad ogni testa di iniezione è associato un estrusore specifico, i quali sono disposti l'uno al di sopra dell'altra, in cui sulla parte della calandra opposta all'estrusore, è previsto un dispositivo per l'ulteriore unione ed il trasporto con uno degli estrusori posti l'uno al di sopra dell'altro.The invention relates to an extruder-calender combination consisting of an extruder and a calender inserted downstream, rigidly connected to the injection head of the extruder. The task of the invention is to provide a structural form of an extruder-calender combination which is distinguished by a reduced structural footprint and in which, after short, almost equal paths, the extruded belts can be assembled so that the product presents the advantages of the "Roller Head" or roller head technology, without presenting internal stresses or stresses. The invention consists in the fact that in the calender support two pairs of rollers are positioned one above the other, that to each pair of rollers or cylinders there is associated a special injection head, in which an injection head is arranged above the other, and that a specific extruder is associated with each injection head, which are arranged one above the other, in which on the part of the calender opposite the extruder, a device is provided for further joining and transport with one of the extruders placed one above the other.
