<p>A belt-type printing machine, primarily for printing large numbers of different bingo tickets, includes a pair of endless belts (8,8') one of which is slightly longer than the other. The belts each carry a series of identically-sized printing plates (16,16'), there being more plates (16') on the longer belt (8'). The plates (16) on one belt (8) are used to print a first sub-area of each ticket, while the plates (16') on the other belt are used to print the remaining sub-area of each ticket, the different lengths of the belts (8, 8') which are rotated at the same speed, resulting in the printing of tickets with different combinations of sub-areas from the plates (16, 16').</p> |
