УСТРОЙСТВО ДЛЯ ГОФРИРОВАНИЯ ЛИСТОВОГО МАТЕРИАЛА

摘要

FIELD: plastic metal working, possibly making of special designation shapes used for making noise insulation panels. SUBSTANCE: shaping members are stationary mounted on shafts. On one shaft shaping members are arranged normally relative to axis of shaft; on second shaft shaping members are inclined relative to shaft axis by angle whose value is selected according to next relation 0 is less than alpha that is less than 90 degrees. EFFECT: possibility for making panels with corrugations allowing to suppress sound intensity. 2 dwg
