DEVICE FOR COMPOSITE MOLDING Russian patent published in 2002 - IPC

FIELD: production processes, in particular, means for molding of abrasive and frictional articles of fibrous materials. SUBSTANCE: the device for composite molding of articles of fibrous materials provides for uniform delivery and deposition of the composite mixture of filaments of staple fiber and binding pitch due to coaxial arrangement and direct communication of the cavities of the shifting chambers, composite mixture, its deposition and depression successively in the direction of mixture deposition. The pressure pipe-line for delivery of fiber filaments is pneumatically connected to the means of pneumatic delivery. For orientation of the transporting flow oppositely to the direction of deposition of the composite mixture the delivery pipe-line is arranged coaxially in the cavity of the composite mixture deposition chamber. The composite mixture deposition chamber is positioned across the device longitudinal axis. EFFECT: enhanced quality of molding of the article blank due to provision of uniform delivery and deposition of the composite mixture. 1 dwg
