Abstract
Abstract A belt-type printing machine, primarily for printing large numbers of different bingo tickets, includes a pair of endless belts one of which is slightly longer than the other. The belts each carry a series of identically-sized printing plates there being more plates on the longer belt. The plates on one belt are used to print a first sub-area of each ticket, while the plates on the other belt are used to print the remaining sub-area of each ticket, the different lengths of the belts, which are rotated at the same speed, resulting in the printing of tickets with different combinations of sub-areas from the plates.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
A belt-type printing machine for printing a plurality of printed sheets, the machine comprising at least two endless belts, and an ordered sequence of printing plates of the same dimensions carried on each of said belts, each plate on a first belt being associated with the printing of a first sub-area of a sheet and each plate on the at least one further belt being associated with the printing of a further sub-area of the sheet, the first and further belts being of different lengths whereby said belts carry different numbers of printing plates thereon, the arrangement being such that, on controlled passage of a series of sheets past each endless belt in turn and on rotation of said belts to move the printing plates thereon at the same speeds, first and further sub-areas of each sheet are sequentially printed by the first and further belts respectively to produce a series of printed sheets each comprising a combination of sub-areas printed from printing areas on different belts, each rotation of a belt displacing the printing plates thereon relative to the plates on the at least one further belt whereby, on continuous rotation of the belts, a plurality of printed sheets each with different combinations of sub-areas thereon are printed.
