BLOWHEAD AND METHOD FOR THE PRODUCTION OF A MULTILAYER BLOWN FILM |
摘要 |
A blow head for production of a multilayer blown film with at least two plastic layers has melt guide areas, which are traversed in succession in the direction of flow (z) of the melt, including feed lines to at least two individual gaps for guiding an individual stream, and an annular gap for combining of the film composite. At least one thermocouple is arranged on at least one flow path of at least one individual stream before the stream reaches the annular gap. |
