Abstract
A size control system of raw silk consisted of at least 4 basic elements (1) a cocoon feeding element (FE), (2) a restoring element (RE), (3) a size-detecting element (DE) and (4) a signal-transmitting element (TE).
A study was carried out to analyse the differences in reliability depending on the relations among DE, TE, FE and RE from the view point of reliability design.
The differences in the theoretical values of reliability were determined for 4 technologically different relations among the elements especially between FE and RE. It is concluded that the reliability of the standby removal feeding system is higher than that of the simple stationary feeding system to a certain computable extent. The reliability could be infinit approaching the value 1 depending on the number of FE as far as the relation between FE and RE concerned in the feedforward process of size control system.
