SYSTEM FOR FEEDING AND MIXING MULTI-COMPONENT MOLDING COMPOSITIONS

摘要

A system is provided for supplying a plurality of different components in controlled amounts and component conditions to a molding machine which comprises a plurality of holding bins (10, 12, 14, 16) for particulate molding composition components, means (110, 112, 114, 116, 118) for drying said components and maintaining the dried condition of the components throughout the system, a separate source (80) for a reinforcing component, means (40, 42, 44, 46) associated with each bin for feeding the components to weighing stations (58, 58', 60, 60') under controlled drying conditions, feeding means (70) for supplying said components and feeding means (84, 85, 86) for supplying controlled amounts of reinforcing component to a mixer (90) and means (92) for releasing a uniform blend of a mixture of particulate components and reinforcing component into a molding machine (96).
