DEVICE TO COOL DOWN PLASTIC SECTIONS Russian patent published in 2013 - IPC B29C47/90 

Abstract RU 2471624 C1

FIELD: process engineering.

SUBSTANCE: invention relates to processing of polymer thermosetting materials and may be used for cooling strip, band or bag section at process outlet. Proposed device comprises extruder with moulding device. The latter supports taper-surface cooling nozzle arranged nearby moulding device and sized to its cross-section. Note here that cooling nozzle consists of truncated cone case made integral with ring and provided with cover. Note also that said ring has conical surface adjacent to moulding device. Besides, said rings has channels to feed and discharge coolant from chamber formed at joint of casing, ring and cover. Casing open end diverges to plastic flow escape.

EFFECT: simplified design, higher quality and accuracy, reduced surface roughness.
