Description

(A 37962

When using the method according to the main patent 388094 it has been shown that that the patterns, e.g. B. for wallpaper and similar types of paper, not so exactly with that Format can be brought into conformity, as is the case with these papers is essential.

According to the invention this is to be achieved in that the sample tube bundle or Sample pots at their radiation outlets are given a diameter that corresponds to that of the wallpaper. Like. Format corresponds.

The usual wallpaper format is 500 mm with edges, without edges about 470 mm, and the sample pot would have to correspond to this dimension get a diameter of about 470 mm at the outlets. But there are also wall coverings that, because they are not glued on, but to be nailed to a larger width, e.g. B. 1000 mm can, and accordingly the pattern device would have a diameter of about 1000 mm at the outlets here. It would be the same with all these patterned ones, on a specific, fixed one Wide sized papers must be kept.

If you work one patterned paper on the paper machine, two extraordinary ones Wallpaper strips, i.e. with a working width of 2 m, you would get along with two sample pots in the machine width and depending on the number of colors that the pattern should have, in the direction of paper travel Cream two or three pots in a row and for a certain type of wallpaper

and two lanes next to each other, e.g. B. 4 or 6 m large sample pots must use. These flat disk-like large sample pots must be specially set up so that they do not become too heavy, especially made of the lightest material, then cut out in the disk and provided with ring channels, channel-like arms or with specially inserted, radially displaceable small sample pots that have their own movement, whereby, in addition to the above-mentioned advantage, a different pattern, especially suitable for wall coverings, is achieved. The sample pots can also have a diameter such that they cover the entire width of the sieve. The drawing shows the new pattern devices, namely Fig. Ι show the top view of part of a wire section with large pattern devices of various types, Fig. 2 the longitudinal section thereof and Fig. 3 a cross section. The lid belts b run on both sides of the machine slider. Between the latter, the new devices apply their patterns to the paper web running on the wire α. The devices c, d, e are each arranged in pairs next to each other over the wire α and pattern continuously in width each half of the paper web, so] that z. B. here two wallpaper webs side by side, with the device f, which sweeps the entire width of the machine, but a machine-wide wallpaper o. The like. Patterned paper web arise. So that these large pattern devices turn out to be quite easy and a wide variety of patterns can be generated, z. B. the device c formed from ring channels c, c1, c2, which are each fed individually, have dye outlets g and sit on a light cross h which is attached to a pipe axis i and which participates in this given rotary movements. The neck bearing k gives the axis i its hold. In the pattern device d, a wheel d provided with straight arms d1 carries the pattern pots / which are radially displaceable on the arms d1. The wheel d1 turns and so does the sample pots, but the latter also each turn around its own axis. The wheel d, dl receives its rotary motion by means of a rope, belt, lever or the like drive from outside the paper machine; the sample pots / can be turned directly by pull-up or electric spring turning mechanisms connected to them. The pattern device e consists of a wheel e, the arms of which are designed like a channel and which dispose of dye g; the wheel e is given a rotating movement from outside the machine. The color can also be introduced into the middle space 0, from where it is distributed into the arms η. The three described pattern devices c, d, e lie one behind the other in the direction of paper travel and together produce a continuous pattern which, however, can be changed in the most varied of ways depending on the colors, directions of rotation and speeds used in the individual devices. The device f consists of a wheel / with arms p that rotates around the hollow axis q; the sample pots I can be arranged radially adjustable on the arms p and provided with their own drive. The pots / can be fed individually or in groups with other colors, and individually with water, so that with this one sample pot / a finished, continuous pattern can be created across the width of the machine. The large devices described also have the advantage over many small ones that the dye lines, the drive and the storage are simpler. Godfather T-Ax sayings: 1. Apparatus for the production of patterned papers and cardboards according to the method of patent 388094, characterized in that the pattern devices so large in diameter that they either cover the entire width of the machine or the width of the format be able to pattern the paper, cardboard or wallpaper strip to be patterned. 2. Device according to claim j, that the rotatable pattern devices (c, d, c and /) with with dye outlets (g) provided with ring channels (c, c ¹ , c ² ) and a spider (h) or with a with arms ( ei ¹ ) provided wheel (d), radially displaceable, its own. Pattern pots (/ ') with a drive or with a wheel (e) provided with channel-like arms (· « ) having arms () or with a single pattern wheel (f>P>1> I) covering the entire width of the paper . 1 sheet of drawings.
