Description

Machine for coloring printing blankets, especially for type printers and small printing machines. The inking of printing blankets, e.g. B. for type printer, - has been a cumbersome and time-consuming job so far, as the cloths are in the containers containing the coloring liquid are immersed and then dried have to. Apart from the fact that this work is a heavy soiling of the hands and Brought clothing with it, the sheets were warped by diving and when subsequent drying unevenly soaked with paint. If necessary, have to the cloths are sent to the institute set up for dyeing, which in turn sometimes a considerable loss of time and expense.

The invention relates to a machine for inking printing blankets, especially for type printers and small printing machines, which the owners of such machines the possibility of coloring the for these machines make the necessary wipes yourself. The machine allows an even and quick coloring of any wide and long cloths, whereby as Another advantage to be emphasized is that the insertion of the wide cloth web on extremely can be done conveniently and without soiling the hands, etc. A warping of the cloth inside the machine is excluded; the cloth is purely mechanical Colored white and dried. The machine is also easy to manufacture and cheap, so that they can be used as an additional machine for the type printer for every small business can be considered.

The novelty of the invention is that the storage of the pressure and stand of the machine serving tensioning rollers is constructed in two parts, in which Way that the one provided with a pressure roller and the tension rollers stand part is hinged on the other, so that all for coloring, pressing and rollers serving to guide the printing blanket for convenient placement of the printing blanket can be exposed.

The drawing shows an embodiment of such an inking machine shown in the side view.

The machine stand consists of yours attached to a base plate Stand part a., On which the Einf: irbewalze b and a pressure roller c are mounted. The inking roller b hisses into the container o that holds the coloring liquid, in which also (never resiliently influenced doctor roller d is arranged in such a way that the ink taken from the inking roller before delivery (read the blanket evenly is stripped. In order to apply a layer of paint of uniform thickness on roller b received, the roller has a corresponding recess in a known manner bl (Fig. 2), which, in conjunction with the roller d, defines the passage cross-section for the Specifies the color exactly. On the stand part a, the second stand part a1 is rotatable at e stored; this carries the second pressure roller cl and the two tension rollers f and the leadership roles; in addition to the winding roller h. By folding the part al The machine can be exposed around its axis c, (let (read on the Supply roll l wound printing blanket k first on inking roller b, then guided over the one pressure roll c and over the guide rolls g to the take-up roll h can be. In Fig. R, the part a1 is in the folded position with dotted Lines indicated.

If (the printing blanket is inserted in the manner described, part a1 is folded upwards until the two printing rollers c, cl come to rest on one another, whereby the required pressure can be set in the desired manner with the help of the tensioning screw Printing rollers c, cl are connected to one another and to inking roller b by a spur gear n, so that when the hand crank q, which is attached to the axis r of printing roller c, for example, is rotated, the rollers mentioned inevitably rotate After the winding roller is also connected to the drive roller by a pull cord, the crank d (las printing blanket h is first pulled off the supply roller l by the press rollers c, c1, then with the help of the tension rollers f tangentially over the inking roller b, which releases the ink in even quantities <into the printing blanket. When passing between the pressurized rollers c, cl, the ink is in the fabric of the cloth is pressed, so that a uniform penetration of the dye and saturation of the cloth is effected. The excess amount of ink remains on the surface of the rollers c, cl and is removed from them by the scrapers p and fed back into (le-i ink container o. When leaving the pressure rollers c, the dyed cloth h is extended over the guide rollers in such a way so that it has already dried up to the take-up roller h. In this way, the cloth k remains taut all its way, so that creasing or warping cannot occur.

It should be mentioned that the machine, depending on its size, for example can also be driven electrically.

Claims (1)

PATENT CLAIM Machine for coloring printing blankets, in particular for type printers and small printing machines, characterized (let the for Storage yaw pressure and tension rollers (c, cl) serving stand designed in two parts is, in such a way that the upper one, with a pressure roller (cl) and the tension rollers (f) provided stand part (an) is hinged on the lower stand part (a), so that all for inking, pressing and guiding the printing blanket (K) serving rollers can be exposed for convenient placement of the printing blanket.
