BENDING ROLLER

FIELD OF THE INVENTION The invention relates to a bendable roll, in particular for applying a sheet material comprising a continuous roll of composite material and a fixed shaft portion which is further provided with a bending apparatus for rolling.

10 The bendable composite rolls in which the sheath is coarser are particularly used as rollers for paper and board machines, the titanium having advantageous material properties, in particular the elastic mode, whereby it can be dimensioned to be relatively easy or to the desired curvature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Fig. 1 is a cross-sectional side view of a semiconductor roll having a composite roll of a composite roll center center shaft 2 having a thicker I and thinner end portions (inner) 22 and (outer) 23 passing through the roll mantle.

Between the inner shaft portion 22 and the sheath 1 there is a protective sleeve 30 (outer sleeve) fitted inside the roller sheath which is fixed: * * «· β to the end of the sheath 1. Inside the protective sleeve 30, bearings 31 and 32 are fitted at their ends and bearing housing 1 arranged almost entirely inside them. support sleeve 33 (inner sleeve). In addition to the roll * 4 * ··; 25 bending apparatus 33 arranged on twisting sleeves 33 and sleeve 33 ···? and bending. For this purpose, an adjusting screw 5 arranged in the outer sleeve 33 of the sleeve 33, which is threaded 4 connected to the shaft part p; in addition, the stub end of the sleeve 33 is articulated by the ball bearing 6 in the shaft portion: the deflection (curvature adjustment) of the wml \ m lane is done by rotating the screw 5, thereby changing the position of the shaft portion 22 and the bearing sleeve 33 3 1 1

In addition, a pivot bearing 7 is mounted on the end of the shaft with a pivot bearing for turning the direction of the arc. In the figure, the forces are received along the axis. The other end portion is in principle 5 except that the axial forces of the bearing are released in the road.

Figures 2 and 3 show other bends according to the invention, Fig. 2 also having a through shaft and a tongue 8 at its end, and Fig. 3 having shaft pins 9 having a thinner outer member 93 and a helical gear 10 at the end. In the figure, the bending forces are transmitted entirely to the frame, and the patterns: between the shaft and the frame.

It will be apparent to one skilled in the art that the various applications of the invention are not limited to the above examples, but vary within the scope of the following claims.
