Per dumbbell is a tube with a semicircular cross-section, its Ends by bolts or the like. swiveling with the as a support beam trained axis are connected.

In the practical embodiment of this feature is the dumbbell with a semicircular cross-section at its ends, each with a forehead plate and a dome-shaped head piece Location rough. ^ e connected for the bolt.

According to a further feature of the invention, the inflatable hose rests evenly on the two parts over its length when the axis and the jacket are parallel. This means that, even if the axis and the jacket are in a parallel position, the sewing scale has a uniform cross-section over its length _o

The invention starts from the basic idea that Tension of the paper web by a uniformly on the To compensate for the line load exerted by the jacket irläiischlauch in its described training and arrangement produces »Ird.

Fig. 1 is a longitudinal section through the device and Fig. 2 is a section along the line II-II of Fig _o 1.

The paper web 1 is guided around the jacket 2 in the counterclockwise direction in the illustration according to Figure 2 and introduced into a calender. The dumbbell 2 consists of a tube with a semicircular cross section and is at its ends 2a each provided with a front plate J, which is of a dome-shaped Part 4 is worn. This has a bearing eye 5, through which a Bolt 6 is hindurciigefuhrt, the recording with its middle part in the end piece 7 of the formed as a support beam 8 rigid axle is mounted. The dumbbell 2, which is semicircular in cross section, can therefore oscillate around the bolts 6 execute, i.e. the ends of the jacket pipe can be swiveled in relation to the support beam 8 »

This has a central section 8a, which is surrounded by the dumbbell, which is semicircular in cross section. Between the lower \ 7and 8b of the middle section 8a of the support beam 8 and the jacket 2, which is semicircular in cross section, an inflation tube 9 is arranged which, as shown in FIG can be seen, is located essentially in the bending plane «The inflatable tube extends over approximately the entire area Length of Ll & ntels 2 and is at its ends by suitable jiiittel, like terminals 10 or others; l. tightly closed.

Ίχι the hose opens a line 11, which is passed through the support beam at 12 and 13. The ends of the inflatable hose can be connected to the jacket 2 so that the inflatable hose always maintains its position. The arrangement and design of the inflation hose is also chosen so that when the hanteis 2 and the wall 8b of section 8a of the support beam 8 are in parallel position, the inflation hose has a uniform cross-section over almost its entire length and therefore also over its length on the two parts mentioned rests evenly _o

Due to the tensile stress of the paper web guided over the dumbbell 2, the jacket takes a bending line 14 corresponding to it Shape. By applying the inflation hose via the line 11, this deflection can be compensated, as well as a positive deflection according to the bending line 15 can be achieved. The deflection after the bending line 14 affects the jacket through the inflatable tube against the line load exerted, whereby a very sensitive infinitely variable bending of the sheath is possible.

The support beam 8 has a moment of inertia which is a multiple of the moment of inertia of the Hanteis 2.
