    摘要： The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process. Embodiments of the present disclosure provide a unidirectional cooling element having a unidirectional cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube. The unidirectional cooling element operably expels cooling gas in a path with the flow of the molten film tube toward an exit gap formed between the unidirectional cooling interface and the molten film tube. The minimum gap between the unidirectional cooling interface and the molten film tube occurs at the exit gap, and advantageously, the unidirectional cooling interface is provided with one or more compound angles to maximize stability and cooling efficiency.

    摘要： Provided is a thickness variation adjustment-type air ring capable of accurately and optimally controlling the volume of cooling air at all positions in the circumferential direction, and stably manufacturing a synthetic resin film having an exceptionally low thickness variation. A thickness variation adjustment-type air ring is provided on a die of an inflation film manufacturing apparatus which locally controls the volume of cooling air discharged from a cooling air passage in a circumferential direction to adjust the thickness variation of a synthetic resin film when blowing the cooling air around a molten synthetic resin tube extruded in a longitudinal direction to cool and solidify the molten synthetic resin tube to form the synthetic resin film, the thickness variation adjustment-type air ring. The thickness variation adjustment-type air ring includes: a ring-shaped passage adjustment portion arranged sequentially in the circumferential direction inside of the cooling air passage; and a plurality of moving portions connected at a predetermined position in the circumferential direction of the passage adjustment portion so as to move a connecting portion of the passage adjustment portion in a predetermined direction independently from other portions, wherein a space in which cooling air can circulate inside the cooling air passage is locally adjusted in the circumferential direction and the volume of cooling air is locally controlled in the circumferential direction.

    摘要： The invention relates to an extrusion die (10) for a film-blowing head (1) of a tube extrusion system for extruding a tube (2) from a plastic melt, having a die body (11), which has a melt duct (12) for producing the tube (2), the melt duct (12) having an annular exit opening (13) for the plastic melt; an air guide (20), which extends through the die body (11) and through which cooling air (3) can flow through an opening (21) in the air guide (20) in order to cool the interior of the tube and through which heated exhaust air (4) from the cooling of the tube interior can be extracted through the opening (21) in the air guide (20). According to the invention, the air guide (20) has a central duct (22) for the cooling air (3) and an annular duct (23), which surrounds the central duct (22), for the waste air (4); an air exchanger (40) is arranged in the air guide (20) in such a manner that the air exchanger (40) directs the cooling air (3) from the central duct (22) outwards towards the die body (11) in the direction of the opening (21) in the air guide (20) and directs the waste air (4) substantially in counterflow to the cooling air (3) outwards towards the die body (11) towards the annular duct (23).
