is ordered, one end of which aul the pitch circle of FIG. 5 The crank disks 1 are rotatable in bearings 15 Crank disk mounted by means of a crank disk bolt. The crank plate is articulated on the pitch circle 13 connected to this while benbolzen? attached. The crank disk can turn the other end can be rotated their axis of rotation 12 by means of a compensating rocker bolt. The compensation scene articulated to the first crank arm 10 is in such a way on the crank disk 1 the is, furthermore a sliding block is arranged, the io of which is arranged that its one end articulated in the crank width that corresponds to the longitudinal slot and the washer bolt 7 is attached. Next to the axis of rotation rotatably attached to a stationary sliding block pin 12, the sliding block pin 6 is fastened around which it rotates, which is arranged adjustable at a distance in the direction of the sliding block 11 bar. The compensatory two moving tables towards the axis of rotation of the arm 10 has a longitudinal cutout 14, the Crank disk Tcrsetzt and a second crank 15 width corresponds to that of the sliding block 11. At the other swing arm hingedly attached to the crank disc bolt end, the balance arm 10 has a leveling element and the centers of the sliding block pin, the swing pin 8, on which the first crank-crank disc bolt and the compensating rocker arm 9 is articulated. When the bolt is rotated on a straight line that goes through the middle of the crank disk describes the point of departure of the sliding block pin leads, the 20 equivocal bolts 7 form a circle with the first one Crank rocker on the first moving table and the knife of the pitch circle 13, during the crank second Crank rocker articulated on the second travel rocker pin 8 is a different one table is connected. Curve describes.

So each crank disk has its own crank on the first rocker arm 9 is a first

In the standard version, the second moving table 3 is connected in an articulated manner. The table traversing device According to the invention, the traveling tables move kinematically on approximately two crank disks. shirt in the same way against the solid wall 4.
