The present invention relates to a machine for continuous processing of leather, in particular to cleat the leather m, t a pair of twin-screw rollers.

Several known cleat machines essentially imitate the hand-made cleat, ie leather is turned over over a knife edge. The hoisting machines are a typical example. These machines, which are already obsolete today, have the great advantage that they are capable of all g g 6 ^. _{def the leather without}

F i g. 5 is a view from above, with the fenders are omitted.

On the machine frame 1 are side walls 2.3 fasten. In the lower part of these side walls are in LaeernO a pair of screw rollers 6,7 supported, the from the engine S via pulleys 9, 10 through V-belts U are driven. Both screw rollers 6.7 wear a left one on one half of their length and one on the second half of their length right helix. In the profile, the helical lines of the two screw rollers are either 6.7 coincident or of different shape.

Above the pair of screw rollers 6, 7 a rectangular frame 11 is rotatably ojaeert in the bearings 12, 13 and carries 15 pairs of discs 16 in forks. The forks 15 are pivotably arranged in the bearings 17. The disks 16 are either made of metal or one of each pair is made of rubber. The planes of the pairs of discs 16 are inclined to the direction of movement of the leather by the angle * (Fig. 1,3). Each disc is rotatably mounted in a fork 15. The end of the bolt 18 of each gear 15 merges into a lever 19 on which a spring 20 engages. The disk pairs are ^g ft from the ausgeuSen of this spring 20 Kra pressed against Gerlie rollers 21 or conical rollers 22 16th The rollers 21, 22 can be adjusted by means of the screw 23 in the bracket 24. The straight rollers 21 or conical rollers 22 are rotatably mounted in bearings 25, 26 and via a chain 27 from the motor 28 via a sprocket 29 and a gear pair 30 of the axis of the roller 21 and the IS is the angle of inclination of the »^^ _of either 0 ° so parallel to the 'f' ^^ Sch dtr leather or inclined to it.
