Abstract

Disclosed is a decentralized control method for a corrugator line characterized by the fact that, in the control method for a corrugator line for the continuous production of corrugated boards including the process of bonding a liner to the corrugated medium so as manufacture a single-faced corrugated board, bonding another liner to this single-faced corrugated board so as to fabricate double-faced corrugated boards or sheets, cutting the boards into predetermined lengths, and the like and having a local control unit provided for each process unit which is set up by dividing the aforenoted series of production processes so as to achieve synchronized production control of the line by means of these unit-process local control units which are allotted different functions and which are linked into a multiplex transmission network. The cycle pulses (that is, the synchronization signal which serves as the production reference for each control unit) that are obtained, when the double-faced or double wall corrugated boards are cut into the required lengths, are used and supplied to the main control unit and each local control unit for the synchronized production control by means of the local control units.
