    摘要: The invention describes a blow head (1, 21, 208) for production of a multilayer blown film (18) with at least two plastic layers, which (1, 21, 208) has at least the following melt guiding areas (16, 17, 25, 205), which are traversed in succession in the direction of flow (z) of the melt: feed lines (25, 205) to the at least two individual gaps for guiding an individual stream at least two individual gaps (16) for guiding of an individual stream an annular gap (17) for combining of the film composite (18). At least one thermocouple (85, 142) is arranged on at least one flow path of at least one individual stream before it reaches the annular gap (17).
