Abstract (en)
[origin: CA2967497A1] The invention relates to a blowing head, a method for producing a blown film and a blown film installation. Specifically, the invention relates to the use of plate spiral distributors (2) in blown film installations. It is proposed that the melt streams in a plate spiral distributor (2) are initially bundled (13, 17, 18) and then forwarded in a bundled manner to a common co-extrusion flow (8).
