Title: Synchronous prodn. line drive system - has wheels of adjacent stations driving common conveyor belt with compensating slide
IPC: B65G47/51
Filed: 1975-12-01
Abstract: The system is for a production line with a continuous or indexing conveyor and having two or more processing stations, each with its independent drive. A non-slip, endless chain conveyor (30) connects adjacent stations on the line and has two driving wheels (12, 22) coupled rigidly respectively to the independent drives of the first (10) and second (20) stations.
