Embodiment Construction

[0023] As shown in the figures, a printing machine 1 such as a flexographic printing machine comprises:

[0024] – frame 2;

[0025] – feeder or feeding station 3;

[0026] - one or more printing units, in the printing press 1 there are five consecutive printing units 4, 6, 7, 8 and 9 arranged in a row and printing five different colors such as black, blue, red, green and yellow; and

[0027] - The discharge end or delivery station 11 of the machine (shown in dotted outline).

[0028] The infeed station 3 receives a stack of board elements, for example boards 12 of unprinted corrugated cardboard, and transfers said board elements one by one to the first printing unit 4 . At the outfeed end of the machine 1 , a transfer station 11 recovers the printed sheet 13 .

[0029] The sheets 12 and 13 are transferred from one printing unit to the other (arrow F), ie in the longitudinal direction from the infeed station 3 to the delivery station 11 . The sheets 12 and 13 are conveyed...

Abstract

A method of adjusting a machine (1) for printing plate elements (12) equipped with at least one rotary impression cylinder (27) includes the steps of measuring a speed of the element (12, 13) passing through the machine (1), generating an operating signal (34) as a function of the measured speed and a tangential speed of the cylinder (27), and adjusting an operating speed of the machine (1) as a function of the signal generated so that the operating speed of the machine (1) is such that the speed of the element (12, 13) is substantially equal to the tangential speed of the cylinder (27).

Description

technical field [0001] The invention relates to a method for automatically adjusting a machine for printing plate elements. The invention also relates to an adjustment device for adjusting a machine for printing plate elements. The invention also relates to a printing press with an adjustment device. [0002] In the packaging industry, printing presses are used to print board elements such as cardboard or cardboard. The machine consists of several consecutive stations. The first station most upstream is the infeed station for the continuous and sequential introduction of the sheets from the bottom of the sheet stack. The feed station feeds a plurality of printing stations in the form of one or more printing units placed one behind the other. Each printing unit prints one color. At the end of the machine there is a transfer station for collecting the printed sheets. [0003] In the case of printing cardboard, and more specifically corrugated board, the most commonly emplo...
