Drew device for cleaning formwork that share the diameter of their HüUkrciscs in the area 2 such as shuttering boards, squared timber or the like. the gap between the two is shown on the shaft one. This device has two pairs of Roller arranged hollow bodies is slightly larger 15 rollers 3. which in operation different Drchzahals have the diameter of their enveloping circle on the outer ones. It can be seen in particular in Fig. 1 that ren ends.

One recognizes this by the fact that in each case particularly good cleaning also of the rollers 3 on one side of the formwork part 2 a curved shuttering board results. It can be connected by chain drives 4, the Ketdie Flexibility of the roller is further improved by this 25 tennki: r of the diagonally opposite one another be that the shaft in the area of the gap between gears is the same size as that of two neighboring woas the two hollow bodies are preferably excellent but different in size. This results in has a rounded incision on its circumference. The one hand is a translation between the cinan gap between the hollow bodies can be about 1mm of the adjacent rollers 3 and on the other hand an equal width being. As a result, sufficient bending 30 is more likely to be a sense of rotation for the two rollers on one side of the possible without the adjacent hollow body device 1.

In the exemplary embodiment, a particularly expedient transmission of the driving force is provided. M ^! <n recognizes that the drive motor 10 has a pinion 11 which meshes with a drive wheel 12 associated with the first roller, that this friction gear 12 meshes with a gear 13 on the diagonally opposite roller and that each roller 3 on one side, such as already mentioned, od via a chain drive. Like. Connected to one another. whose sprockets have a different number of teeth. It can be seen above all that the gears 12 and 13 engage the rollers 3, the spacing of which remains constant even when pivoting. As a result, this non-positive transmission of the drive is possible despite the pivoting movement of one of these rollers 3. For good guidance of the formwork piece 2, it is useful if the opposing rollers 3 are arranged in such a way that, even in the end positions of the pivoting movements, one roller each comes to lie opposite the space between the two opposing rollers. The best guidance is achieved for a formwork part 2, the strength of which just makes such a pivoting 'Jcr rollers 3 necessary that two rollers are exactly opposite each other. This arrangement of the rollers is achieved by a sufficiently large distance between two rollers that are effective on one side of a formwork part 2.

According to FIG. 3 and 4, the rollers 3 have radially arranged, elastically resilient scraper boxes 14, preferably of about the same strength throughout. The rollers 3 have one mounted on a shaft 15 Hollow body 16 with millings 17 along its surface lines. in which the scraper strips 14 can be used are. The Einfräsimgcn 17 are closely spaced on the circumference, whereby the Effectiveness of the roller 3 is increased. Due to the elasticity of these Schabelcisten a filling is possible the gaps 18 between the ribs largely prevented, since these gaps during of the company alternately expand and narrow depending on how the scribble strips are deformed.

en.

The scraper strips 14 are exchangeable. It can be seen that on the end faces of the individual hollow bodies 16 provided with an annular edge 19 in recesses 20 on the narrow end sides 21 of the scraping strips 14 engaging retaining disks 22, preferably fastened to the hollow bodies 16, are provided are. In the exemplary embodiment, these are detachably fixed with the aid of Secgerringcn 23. Single or all scraping iron 14 can easily be replaced if they are dull, worn or damaged are.

In Fig. 3 it is shown that a roller 3 has two has a through shaft 15 seated, each provided with scraper strips 14 hollow body 16, to it is provided that the Schabelcisten 14 of a roller 3 are designed so that the diameter of their Enveloping circle cs // in the region of the gap 24 between the two arranged on a common shaft 15 Hollow bodies 16 is slightly larger than the diameter of their enveloping circle at the outer ends on the roller 3.

The shaft 15 of the roller 3 has a gap 24 between the two hollow bodies 16 in the region of the gap 24 preferably rounded incision 25. As a result, the roller 3 is easier to bend at this point possible. For this bend, there is a small distance between those located on a common shaft 15 Parts of the roller required. It is enough. when the gap 24 between the hollow bodies »5 pcm 16 is about 1 mm wide. so that there is Concrete is also broken loose.

For cleaning the narrow sides of shuttering boards or the like are not driven on the device Rollers 27 with scrap boxes 14 beforehand. whose longitudinal axis is perpendicular to the axes of the rollers 3 and at an angle to the direction of advance of the cleaning formwork parts 2 are available. The feed movement of the formwork piece 2 causes this inclined rollers 27 pressed against the narrow sides of the shuttering board a rotary movement, which, however, also has a scraping effect on the narrow side of the Formwork board causes. These rollers 27 can therefore be constructed similarly to the cleaning rollers 3. However, a subdivision is not provided.

In the embodiment it is provided that one of these rollers 27 on a pivot lever 8 for the Bearing block 6 of the pivotable rollers 3 and the other on one od via a bevel gear 28. Like. Adjustable carriage 29 are arranged. The height of the stored on the carriage 29 Roller 27 is steplessly adjustable with the help of the bevel gear drive 28, so that the shuttering boards are different Widths can also be cleaned on their narrow sides.

The axes of the rollers 3 are arranged vertically
