Abstract

The coloring roller is designed for creation characters by mechanical means on coils, especially in computing machines. The essence of the device is to allow fluid flow to flow smoothly colors on the surface of the dye roller for creation characters, while ensuring smoothness counting machine operation. Remove densifying the surface of the dye roller as is the case with the hitherto used dyes rollers and remove partial damage — we wear out characters on character cylinder. Coloring roller for character creation according to the invention, of which the main functional part is a cylinder of pressurized porous material, strung on the perforated tube allows you to extend your lifetime and thus more economical use of calculations machines.

Description

(54) Coloring roller for character creation

The dyeing roller is designed to produce characters by mechanical means on coils, especially in calculating machines. The essence of the device is to allow a continuous transfer of the liquid ink to the surface of the coloring roller for generating the characters, while ensuring the smooth operation of the calculating machine. This eliminates the densification of the dyeing roller surface, as is the case with the dyeing rollers used so far, and eliminates partial deterioration — we wear the characters on the character roller.

The dyeing roller for producing the features of the invention, the main functional part of which is a pressurized porous mass, firmly threaded on a perforated tube, allows to prolong its own life and thus more economically to use the calculating machines.

The present invention relates to a dyeing device for the formation of scratch marks on coils, in particular in the case of computerized strips ^.

In the prior art dye rollers used in conventional practice, the hollow roller body is formed as a single unit of dense porous material, with closed cells and a filler opening for the liquid dye that passes through the axis of the dye roller. A disadvantage of this formed dyeing roller is that the dense porous material reduces dye transfer while gradually drying, making the dyeing roller unusable. Another disadvantage is the gradual hardening of the paint roller surface, which results in faster wear of the marks on the emblem roller.

By way of example, the dyeing rollers used in the practice of Facit strainers, wherein the hollow body is made of dense porous material, with a filling opening in the axis of the roller, are used in practice. There is an absorbent mass in the cavity, which is absorbed upon injection of the dye. In the operation of the saloon, the dye grows through the pores of the hollow body to its surface, from where it is transmitted to the emblem by the impact of the keyboard. By permanently rubbing the marks on the dyeing roller, the surface of the dyeing roller body is compacted, reducing porosity and increasingly less dye transfer to the dye surface until the pores are completely clogged and dye transfer is prevented.

These drawbacks are overcome by the mechanical dyeing roll on the coils of the present invention which, by having the surface formed of a resilient porous material, permits stable and uniform dye leakage to the surface, while permanently rubbing the marks on the dyeing roll surface. compaction. In the case of a coloring roller so formed, the wear of the characters on the symbol roller is prevented.

This solution ensures a smooth and reliable operation of the calculating machine, which depends at least on a uniform and stable transfer of the dye to the surface of the coloring roller for character formation. Simplicity of maintenance is ensured - replenishment, as well as simple manipulation with the tarbacin to create the characters. The dyeing roller thus formed is industrially difficult to manufacture, while in the manufacture of the individual functional parts, such as plugs and a perforated tube allow the use of lightweight materials such as plastics.

An example of an embodiment of a coloring roller for generating features is shown in the drawing, wherein FIG. 1 shows a cross-section through a dyeing roller, and FIG. 2 shows a longitudinal section through a coloring roller for generating features.

The coloring roller for forming the characters by mechanical means on the coils, in particular in calculating machines, consists of a perforated tube 1 of circular cross-section on which a cylinder of pressurized porous mass 2 is tightly threaded. The hollow space of the perforated tube 1 is closed by plugs When filling the liquid paint into the cavity formed, the plugs 3 are provided with a filling opening 4, which is outside the axis of the coloring roller for generating the features.

In the event of physical or other damage to the absorbent porous mass 2, the plug 3 is loosened by pulling in the direction of the coloring roller axis before generating the features, and after pulling off the absorbent porous mass 2 from the perforated tube 1, 2. After closing the hollow space with a plug 3, a liquid ink dose is injected through the filling opening 4 into the cavity space.

After rotating the inking roller several times, the liquid paint leaks evenly onto the surface of the absorbent porous mass 2 and the inking roller is operable.

The possibility of using the ink rollers to produce characters by mechanical means on the coils is particularly useful in calculating machines where liquid ink rollers are used to transfer characters from the character roller to paper and the like.
