Methods of bonding a printing plate on a base film and an apparatus therefor are disclosed. The apparatus includes a pair of support mechanisms, one of which is horizontally located and the other of which is disposed at a right angle with respect to the horizontal one. A strip of paper is reeved around the horizontal support mechanism, while a strip of film is reeved around the vertical one. A plotter is provided above and in conjunction with the horizontal support mechanism for marking the location on which to place a printing plate, on the paper reeved around the horizontal support mechanism. A half mirror is disposed in close proximity to both of said horizontal and vertical support mechanisms for projecting the location marked on the paper onto the film reeved around the vertical support mechanism. Using a lifter, the operator looks down the half mirror to view the location of a printing plate as projected onto the film, and bonds the printing plate to the base film in that projected location.

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.

Disclosed herein is a method and means for replacing upper and lower corrugated rolls in a single facer having a cassette frame for rotatably supporting the upper and lower rolls and a main frame to which the cassette frame is detachably connected. The method comprises the steps of suspending and moving away the cassette frame apart from a predetermined mounting position in the single facer, keeping a spare cassette rotatably supporting other upper and lower rolls waiting in a suspended condition and fixing the spare cassette frame to the predetermined mounting position in the single facer in place of the cassette frame removed. Means for performing the method is disclosed which comprises a cassette frame rotatably supporting the upper and lower rolls; and a main frame carrying a pressure roll and a gluing unit. The cassette frame is detachably connected to the main frame.
