Embodiment Construction

[0017] figure 1 A printing press 1 for printing sheets by inkjet printing is shown. The printing press 1 comprises a plurality of printbars 2, each of which ejects a different ink. The printbars 2 are structurally identical and are shown by way of example in the figures described below.

[0018] exist figure 1 The printbar 2 is shown in side view, while in Figures 2 to 4 The printbar is shown in top view in , where, in image 3 and 4 China is relative to figure 2 An enlarged detail shows the printbar.

[0019] figure 2 It is shown that the printing bar 2 has a support rail 3 which can be configured as a rail or as a frame. The carrying bar 3 extends vertically or longitudinally to the conveying direction of the printing material, and the conveying direction of the printing material is Figures 2 to 4 Middle is the vertical direction. about figure 1 , the bearing bar 3 extends longitudinally perpendicular to the plane of the drawing.

Abstract

A printing bar (2) for ink jetting comprises a load bar (3), a row of head holders (4) and print heads (5), said head holders being carried by the load bar (3), said The print head is held by a head holder (4). The head holders (4) each have lateral guide profiles (8, 9) for linearly guiding the head holders (4), wherein the guide profiles (8, 9) of the respective adjacent head holders (4) 9) Cooperate with each other.

Description

technical field [0001] The present invention relates to an inkjet printbar comprising a load rail, an array of head holders, and printheads, the head holders being carried by the load rail, and the printheads being held by the head holder. [0002] The printbar is used for page-wide inkjet printing, the print heads being arranged in a row which extends over the format width of the sheet or web. Background technique [0003] In WO 2014160219 A1 a printing rod is described which is complex to manufacture. A large number of components are required to fasten the printing head on the carrier beam, which results in long tolerance chains with small component tolerances. Furthermore, the components are not robust and need to be adjusted very carefully. Contents of the invention [0004] The object of the present invention is to provide a printing rod which is simple to manufacture and robust to operation. [0005] This task is solved by a printbar for inkjet, said printbar comp...
