Abstract

334,183. Beaune, S. May 22, 1929. Inking-apparatus. - In multi-colour printing from a single engraved plate or cylinder, the inks are applied to the printing-surface by a number of inking-rollers having relief surfaces corresponding to the areas of the different colours to be applied, and the surplus colours are removed by a wiping-roller from which the colours are continuously removed. The inking-rollers are provided with an elastic and easily cut coating, e.g. of wax, whitening, gelatine, and glycerine, and are of a circumference equal to the length of the design to be printed. In preparing the rollers for inking, they are placed in the machine and an inked impression from the printing-surface is applied to each roller. The surface of each roller is then cut away to leave in relief only that portion corresponding to the colour which the roller is required to apply. Each inking-roller is supplied with colour from a fountain Q, Fig. 3, by a steel roller P having a milled surface, a steel blade S removing all colour except. that in the recesses of the roller. The wiping-roller is provided with a coating of a composition similar to that of the inking-rollers and is rinsed with alcohol, after which it is rotated in a bath of a saturated solution of alum. After drying it is maintained at a temperature of about 3‹ C. for at least 24 hours and is then rubbed with chamois leather. It is mounted in the machine and driven so that, during the wiping operation, its surface moves at the same speed as the printing-surface but in the opposite direction. To clean the roller after the wiping operation, its surface may pass in succession under a reciprocating brush B, Fig. 6, supplied with a solvent such as carbon tetrachloride, a rubber blade Z, and a steel blade Y which conveys the removed colour into a container N. The roller may be surmounted by a bell-shaped casing provided with a suction device. An alternative method of cleaning the roller consists in causing it to rotate in a bath O, Fig. 7, of solvent in which are mounted reciprocating brushes U rotated in a direction opposite to that of the wiping-roller D. A rubber blade Z removes. the solvent and colour.
