Distance at the exit roller pair is much smaller than 1st at the input roller pair.

A machine for rolling out Seig is known in which several pairs of rollers are arranged vertically one above the other within a frame, with an endless canvas being provided between the pairs of rollers to transport the dough the lower pair of rollers has a higher peripheral speed than the previous one. This machine (see Austrian patent specification 66 348) has the technical part that the entire door direction only works when the WgpLeen runs approximately vertically above one another, and the dough must always be guided from above into a pair of bulbs below. Among the rollers resulting gaps where scrapers must be mounted so that you through this whole structure of a very large and heavy machine receives, as it is not very straight in a bakery readily usable · It is also like

note that the roller pairs must be adjusted individually, which is very time consuming and The purchase of such a machine is only necessary when producing large quantities, e.g. in a biscuit factory appears displayed.

A similar device in which the pairs of rollers are also superimposed, but in an incline

are arranged, is In the üS-Patentsohrift 2 691 shown and described this machine is disadvantageous in that it is always between the rollers Transition pieces must be provided to which sensitive dough very often adhere, so that the dough has to be peeled off again, what means considerable loss of time. On top of that, the whales are not adjustable, so one Machine only for very specific, standardized, so to speak Pieces can be used and you are bound to this size and possibly the type of dough, well not all doughs can be rolled out with it Such a machine is in place if you they only apply to a very specific type of pastry wants to use, so ζ * B. for croissants or any other particular pastry "

Finally, another known machine is described in German patent specification 1 048 845, where however, roller groups of four orphans each are combined. This known device can only be used for partially proofed bread doughs that have been re-used to achieve an even volume to achieve in the division. They are Rollers cannot be adjusted and you cannot roll out the dough thinly, e.g. down to the starch of just one millimeter.

Finally, a dough rolling device is also known in which a number of rollers in two rows on top of each other and provided horizontally

are, however, these orphans, as well always face each other directly in the known facilities discussed so far. Also here are Intermediate pieces are always necessary between the rollers so that the dough does not somehow get between the rollers pulled in, he is also liable well-known establishment also the Haohteil that not all types of dough without sticking over such Intermediate pieces slip so that here too the machine and the dough are repeatedly stopped must be promoted 'So one can do such a thing Device as described e.g. in British Patent Specification 220 056, for whole only Use certain firm doughs, such as those used for biscuits and specialty baked goods.

In the device according to the invention, the in two rows of rollers offset from one another, i.e. they each stand on a gap, so that in this way any scrapers or spacers are not needed. Since the Offset of the rollers to each other is arranged so that each of the first roller of the top row only in the direction of the first roller of the lower row exerts a bridge and so does the second Roll the top row onto the second roll of the. bottom row and follow in this way all other rollers, you get the advantage that each one roller of the top row on the one hand as a pressure roller and on the other hand, in cooperation

with the second lower roller only as a conveyor roller, for conveying the dough onwards.

If, furthermore, the rollers should approach one another, or can move away from each other, with which the passage profiles for the dough can be changed and thus the speed of the rollers is adjusted proportionally, it is ensured that the dough, no matter what kind of dough it is, always processed correctly and not in his own The elasticity and its connection is disturbed. Ea, the tearing of the dough structure is thus also avoided. You can with the invention The device can process any dough, not just dough for special baked goods, as it is any desired setting can be carried out. There are also favorable effects on the bread dough Results, especially with wheat bread or for types of bread that contain a lot of wheat flour.

Further features of the invention result., from the following description of an embodiment in connection with the drawing and the claims.

It show, in schematic sketches,

Ee are two superimposed in Figures 1 and 2 Rows of rollers, indicated by the circumferential circles, outlined, being explicit it should be noted that there is an approximately horizontal one Arrangement is shown, but that these superimposed rows of rollers also under one Can be at an angle to the horizontal in their entirety, or also vertically to the horizontal.

There are four reels in each row supposed to be there Of course, fewer or more such rollers can also be used.

The rollers can be driven by a single one common drive motor via gear ratios or via Kettenradaiitrisbe or via V-belt drives and similar things happen} but it is also possible without further ado, single drives or to provide drives in pairs »

In Figure 1, dfce rollers of the lower row are designated with 1, 2, 3 and 4, the rollers of the upper row with 1 ^! , 12 »13 and 14. In FIG. 2, the lower rollers have been labeled 5, 6, 7 and 6 and the upper rollers have been labeled 15, 16, 17 and 18.

You are now at the top row of rollers Variant, which is shown in Figure 1, is placed on the gap below the rollers of the lower row, that it is offset slightly to the right opposite this

are, while in the design as shown in Figure 2 tends to put the upper rollers against the lower orphans, to whom they are also on gap, are offset slightly to the left. :

In both cases, however, the arrangement is such that in each case an upper roller exerts pressure on one of the lower rollers, but no pressure on the lower roller next to it. In Figure 1, therefore, the rollers exert a pressure on roller 1, as do roller 12 on roller 2, roller 15 on roller 3 and roller 14 on orphan 4V thereby so that no pressure _p is in the direction of each subsequent lower orphan exerted, ie, it practicing the rollers 11> 12, 13 on the lower rollers 2, 3, any pressure · ":; ■.. -

The same also applies for the variant according to FIG Z ₉ because there is from the rollers 15, 16, 17, 18 respectively on the rollers 5, or "6 or * 7 Bew x 8 a pressure is applied during the other hand, by the upper rolling to Fine pressure is exerted in each case on the preceding lower roller, the rollers 16 do not exert any pressure on the roller S *> ew '17 on 4i # Wale © 6, or 18 on the roller 7.

At this point the greatest distance 10 -from each other to have. ! This distance between the rollers is reduced to the point where the rolled out and much thinner dough reaches a fig finish 19. There he eats Distance 20 between the opposing rollers 1 and 11, for example. 5 and 15 much lower than the distance 10, i.e. it corresponds to the final used dough thickness.

Depending on how you now approach or move the upper and lower rollers apart, you can put smaller or larger amounts of dough in the feeder 9 in the machine and depending on how large you set the gap 20, you get then dough of a correspondingly thin layer, the you can optionally bring up to a thickness of only one millimeter.

In order to be able to adjust the distance between the opposite rows of rollers, one can provide the most diverse possibilities. A simple set-up for this, on the basis of a roller arrangement according to FIG. 1, it is sketched in FIG. Here are in the The lower rollers 1, 2, 3, 4, 21 are provided with five rollers each on both rows of rollers Machine frame 24 stored, while the upper rows of rollers 11, 12, 13, 14, 23 of corresponding Carriers in which the bearings of the rollers are used are included, whereby these carriers'

can then be combined into a kind of box 25 The machine frame is trough-shaped in its upper part 26 and, for example, on the two Side walls are provided with racks 27 and 28. The box 25 is inside this trough in guides not shown in terms of height movable and should, if possible, adjust the gap widths, i.e. the distance, with one movement of the upper rollers may be possible from the lower rollers. This can be done in various ways, mechanically, done electrically, hydraulically or pneumatically and is only a simple example of FIG such Verstellmögliohkeit outlined. By doing Box 25 are arranged opposite the racks 27 and gears 29 and 30, on which levers 31, or * 32 are attached. From these levers 31 and rods 33 go baw. 34 on an angle lever 35, which is provided with a handle, not shown, with latching pawl, so that it is by means of a Detent can be fixed in any position. By pivoting this lever 35, in the two Directions of arrow 36 can be seen aleο each other opposite rows of Walsen approach or move away from each other, so that the desired Dough dioke at output 19 can be set.

In Figure 3 it is also indicated that _t the two opposed cylinder rows via a common chain 37, can range from a gear 22 from which drive, in which case corresponding sprockets; are interposed and, if necessary, the further drive to the other rollers also takes place via gears.
