Embodiment Construction

[0021] In Figures 1 to 3 a printing press 1 is schematically represented, comprising a frame 100 in which the web supply station 2 and the printing station 3 can be seen.

[0022] The printing station 3 comprises a printing head 4 which moves back and forth in direction A. As shown in FIG. The printing head 4 is arranged above the printing table 11 and a cutter 12 is positioned at its right-hand end.

[0023] In the supply station 2 two reels 5a, 5b of the paper web W have been arranged one above the other, the upper reel 5b being supported by a retractable support 13 . The next reel 5a is supported by means not shown and rewound in the direction of the curved arrow in order to supply the web W in the direction B.

[0024] To transport the web W from the supply station 2 to the printing station 3, two drive rollers 6a, 6b are arranged a short distance downstream of the reel 5a and two drive / press rollers are arranged a short distance upstream of the printing station 11 Compo...

Abstract

Printer comprising at least one support for a roll of printing paper web, a printer station including a print head , means for conveying printing paper web from the roll to the printer station, driving means adapted for selectively driving the conveying means in a downstream conveying direction or an upstream conveying direction, a cutting station downstream of the printer station for cutting the printing paper web, means for detecting the passage of an end location on the end portion of the printing paper supplied from the roll and conveyed in downstream direction to the printer station, controlling means for controlling the print head including means for entering and storing a printing job, the controlling means further including means for receiving a signal from the detecting means indicating the passage of the end location of the roll of the paper web and then to interrupt the printing job and to deactivate the driving means so as to hold the printed paper web upstream of the cutting means for a drying period, and after that drying period to operate the driving means again for conveying the dried paper web portion located upstream of the cutting means in upstream direction to discharge it from the printer.

Description

technical field [0001] This invention relates to printing machines. In particular, the invention relates to printing presses suitable for printing paper arranged on rolls. Background technique [0002] A printing press for printing paper arranged on a roll is used to print a range of printing jobs. The required web length for the total print job entering the press will not correspond to the web length on the roll. Therefore, when the end of the web is close to the printing head, the printing press will also be busy with printing tasks. [0003] Known printing presses are provided with sensors for detecting the web end and control means for stopping the printing head when the web end is detected. The sensor is located between the web and the first set of web drive rolls. Another drive / press roller assembly is arranged directly upstream of the printing station. [0004] After the printing press has been stopped, the printing press must be ready again to continue the print...
