Abstract

FIELD: different cooling around the edges of film tubing extruded from thermoplastic artificial material. SUBSTANCE: materials is blown for production of film with the aid of a blow head, from which the tubing is blown by differently heated or cooled around its edges cooling air, whose specific feature is the fact that cooling air introduced in the annular built-up chamber is divided into a great member of flow jets differently heated or cooled with the aid of heating appliances located in separated flow jets and radially directed to the film tubing being extruded. EFFECT: facilitated procedure.

Изобретение относится к способу различного охлаждения по периметру пленочного шланга, экструдированного из термопластичного искусственного материала, который раздувают затем для получения пленки с помощью выдувной головки, из которой шланг выдувают различно нагретым или охлажденным по своему периметру охлаждающим воздухом, отличительной особенностью которого является то, что охлаждающий воздух, вводимый в кольцевую сборную камеру, разделяют на множество направленных радиально на экструдируемый пленочный шланг отдельных струй потока, по-разному нагреваемых или охлаждаемых с помощью нагревающих устройств, расположенных в отдельных струях потока.The invention relates to a method of various cooling around the perimeter of a film hose extruded from thermoplastic artificial material, which is then blown to produce a film using a blowing head, from which the hose is blown with cooling air differently heated or cooled around its perimeter, the distinguishing feature of which is that the cooling the air introduced into the annular collecting chamber is divided into a plurality of individual sweat jets directed radially to the extrudable film hose Single variously heated or cooled by means of heating devices arranged in separate flow streams.
