Description

"Regulator for controlling a flexible material sheet of fabric, paper, plastic film or the like

The object of the invention relates to a regulator sum controlling a "flexible material web made of fabric, Paper, plastic film? CU like * against right or Left course, consisting of two end shields connected to one another by a drill or the like, which on both sides of the pipe transversely to the direction of travel of the Y / arenbahn in each case one revolving regulator roller and one in the middle Have pivot point.

Material webs made of paper, fabric, plastic film or the like must be used in the paper, textile and oil industries be guided without wrinkles. As a result, these vJarenbahnen are passed over spreader rollers that smooth the tissue, stretch it out to the side and

go straight ahead as far as possible. In the case of the Varenbahnen, however, it is very often the case that they disengage from their point of view and, for these reasons, should run.

To prevent this skewing of the Varenbahnen, cream guides are zxm. independent straight-line practice of material structures known. These devices are particularly used in textile finishing machines, such as calenders, drying machines, finishing machines, spreader systems or the like To grasp edges, to sxraffen the fabric and to guide it onto the putty of the infeed rollers. The fabric web guide - in general, two fabric web guides are required, of course, consists of a pair of guide rollers, which are pressed against each other by a spring tensioner. T> the pair of guide rollers does not have the varicose edges between them and is set in rotation by the continuous fabric web *

Instead of SewebebaVruilhrern you can connect also regulators -> end. 1-he known regulators consist of one cylindrical Hohr cd. Like. That through on both sides

an end shield is completed, the end shields at the same time having the task of the left and to the right of the tube arranged regulating rollers to be rotatably supported «, The cylindrical tube of the regulator v / eist a centrally arranged pivot on which the regulator in the horizontal plane to the left or swivel to the right.

Regulators of the type described above have not really proven themselves in practice. «This is because that such a regulator has a certain inertia in terms of regulation, which thereby is conditional on the fact that between the locking cylindrical tube and the web of fabric sliding over it a more or less different frictional resistance occurs across the entire pipe width.

Furthermore, devices have become known in this context, v / elche an overflowing ligament with great tension for the puncture intended for it, e.g. 3. Steel belt, require »To put the steel band under tensile stress, it is necessary to achieve correspondingly large To generate adjustment forces, which are capable of sliding friction, which zv / iochen the surfaces of the Lp.ferbucks arises to overcome. Here, the tax effect is caused by shifting weight and by asymmetrical

-A-

Distribution of the frictional forces on the grinding spar is generated, with the force triggering the control process running in the direction of the bisector of the required angle of wrap ₀

From this knowledge a device has become known, the. label is identified by the combination one in the vertical axis direction below that of the running direction the '..' arenbahn opposite the regulator roller arranged Turning and tipping point, located at both ends below the regulator rollers, in the direction of travel Material web - crimped and tapered career paths and from both ends arranged on the cylindrical tube, adjustable angle lever with at the end in the vertical axial direction lying below the regulator roller guide rollers, the Guide rollers rolling on lateral tracks Support and regulate the position of the "arenbahn" Keep in position, while the guide rollers on the raceways when the arena is in an eccentric position unroll and the regulator simultaneously a rotary movement in the horizontal and a tilting movement in give the vertical,

It is therefore necessary to use a spreader roller once to be used in conjunction with a ". arenbahnfükrerpar.r or a regulator. On leden? ■ · !! two guidelines must be used, namely

■ · ■ AA

once a spreader roller for spreading the V.'arenbahn and another a ",, 'arenbahnfükrerpaar" resp. a regulator for driving straight ahead of the var-bahn. It is obvious that this certain disadvantage does not result in pur.cto, expense and costs, in particular because two Ξ: Ώ directions are used.

To orange in this respect the combination of spreader roller and regulator, a strand spreader with built-in regulator for controlling a web of textile goods or the like against right or left direction has become known. These strand spreaders serve to unravel the material webs : · ■ to keep them neat at the same time. In the relevant industry it can now very often happen that "webs of the most varied of widths are driven. It means that the strand spreader with built-in regulator for the widest" ..arer.bahn is constructively designed and also then v / erden only uses, v / enn, for example, buckle "> .T.renbal: ner. gefai.ren '.rerclen. With completely buckle',. 'r.rencahnen there is then the disadvantage that: the regulator opens drund his lcerreite did not achieve the desired effect according to his task
