"Retaining device. In front of the tape reel for winding up Slit strips "■ ■

The invention relates to a 'restraint device the tape reel for winding up slit tapes, 'esp. Metal strips in strip production or processing plants, viobei the restraint rollers compared to the motor-driven ones The tape reel is braked regeneratively.

When winding metal strips after result depending on the thickness of the individual slit strips different laps on the tape reel, i.e. the thicker ones Slit strips form laps with a larger diameter and these therefore take on an ever-increasing proportion am overall train and are therefore wrapped too tightly, while in

Conversely, the thinner slit strips / increasingly looser Wraps are formed. For this reason one has band gap

309842/0130

systems already connected downstream of individual reels according to the number of slit strips “But this is very time-consuming and is worthwhile at most in special cases but not in the general application with frequently changing broad range.

Here, according to the invention, a retaining device from the tape reel for winding up slit tapes, especially «, Metal strips in strip production or processing plants, with the retaining rollers opposite the motor-driven ones Tape reels are braked regeneratively, which the tape tension over the individual slit strips independently maintains its thickness and thus ensures din winding with specifically uniform tape pulls, -so that on the The subsequent tape reel creates tightly wound laps. The restraint device according to the invention characterizes to this end, in that the roller shell of the retaining rollers is rotatable under friction on the retaining shaft stored hinge is divided, the transferable braking torque is preferably adjustable. In this way it is achieved that each Slit strip is held with the same specific retention force against the train of the common strip reel.

The roll shell is divided into the rings most expediently so that the narrowest strip of tape runs on: at least more than one ring "

Further details of the restraint provisions "according to Er- f finding are below. .Hand 'the drawing "for example j shown, and jprai "'show:

Fig. 1 the schematic structure of a sqlchen restraint device,

Fig. 2 shows the view and the longitudinal section through a retaining roller according to the invention and

3 and 4 show two sections F of different ring arrangements on the roller jacket.

As Figo 1 of the drawing shows, there is the retaining device from the machine frame 1 with, for example, a pressure roller 2 and two deflection rollers 3 and A- on the inlet side E and two further deflection rollers 5 and 6 on the outlet side Α «Here is to insert the tape, here the sub-belts 7, the guide roller 4 on the inlet side E and the

309842/0130

Deflection roller 6 on the outlet side A in each case from position 4a in direction B to 4 or 6a in direction G to 6 by means of Pivoting mechanism 8 or 9 can be brought and the pressure roller 2 accordingly from position 2a in direction D to FIG this is known per se. Likewise, the folding table 1o is used in the usual way to introduce the partial belts 7 when starting up.

According to Pig. 2 to 4 the backing ewalz en 2 to 6, the number of which depends on the required retention effect can vary, divided into retaining rings 11 on the roll shell, which on the retaining shaft 12 below Friction are stored and the transmittable torque is adjustable.

Correspondingly, these retaining rings 11 are supported _{in a rolling manner in accordance with 3Pig o} 3 at 1J or in accordance with FIG. The retaining rings 11 can be pressed together or released against the fixed annular flange 19 for setting the desired braking torque by means of an annular flange 18 actuated by pressure medium. The hydraulic, pneumatic, electromagnetic or the like actuation of the ring

flange 18 takes place via the supply line 2o. The restraint shaft 12 is rotatably mounted at 21 and 22 and here · braked generatorically from 23, whereby the restraint tension is built up against the tape reel, which according to the invention is distributed specifically evenly over the entire bandwidth of the individual slit strips by means of the retaining rings 11 and regardless of their thickness, so that an unequal sag results thereof, while the individual winding tapes are wound specific evenly on "the tape reel ₀ for a given tape tension the printing and TJmlenkwalzen can be with respect to centrally control the adjustment of the respective torques of the retaining rings each roll «
