Improvements in or relating to web printing machines

1,037,467. Screen printing machines. FRITZ BUSER A.G. Sept. 18, 1964 [Sept. 18, 1963], No. 38266/64. Heading B6C. In a web-fed screen printing machine in which the web is stuck to an endless conveyer belt for presentation to a printing station, the upper flight 2a of the belt is intermittently movable whilst the lower flight 2b moves continuously. This is achieved by passing the belt around two rollers 3 and 4 each of which is mounted in a carriage 17 movable along rails 18 the carriages being joined together in fixed relative positions by an endless chain 19. Hydraulically operated gripper elements 10 are used to intermittently advance the combined web and upper belt flight 2a to a position on the printing table 1, such forward movement also causing similar movement of the roller carriages 17. Whilst the flight 2a is stationary a motor and chain drive 32, 31, 30, 29, 28, 25, 24 and 26, Fig. 2 (not shown), causes retraction of the carriage 17 carrying the roller 3, the latter roller carrying a suitable sprocket-wheel 23 for this purpose such wheel engaging the chain 24 of the motor and chain drive. The motor is of variable speed being controlled by an element 33 connected by a rod system 34 to the carriage 17.

It is stated that a rapid change of printing format can be acheived thereby by changing the selection of which cartridge is to be in printing engagement with the web. Out of use cartridges may be exchanged while the press continues to print with the selected cartridge. ...

Processing paper and other webs

A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the unit(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.
