Description

me der Lager 18. Die gesamte Länge dieser Walze über die Lagerzapfen ist mit L₂ angeführtme of the bearings 18. The entire length of this roller over the bearing journals is indicated with L ₂

Man erkennt in dem dargestellten Beispiel, daß die Lagerstellen beider Walzen 10 und 16 einander gegenüberliegend angeordnet sind. Der Rohrmantel ist also über die Länge der Walze 16 verlängert und an seinen Enden in den Lagern 15 auf dem Joch 11 geführt Zum Andrücken der Walzen gegeneinander, um die nötigen Quetschdrücke auf die Warenbahn 22 auszuüben, kann entweder, wie es dargestellt ist die Mantelrohrwalze 10 durch Verschieben des Jochs 11 im Gestell 21 mittels hydraulischer Kolben oder dergl. 20 verschoben oder aber auch die Walze 16 im Gestell 21 verschoben werden. It can be seen in the example shown that the bearing points of both rollers 10 and 16 are opposite one another are arranged. The pipe jacket is therefore extended over the length of the roller 16 and at his Ends in the bearings 15 on the yoke 11 to press the rollers against each other to the necessary Exerting squeezing pressures on the web 22 can either be the tubular jacket roller 10, as shown or by moving the yoke 11 in the frame 21 by means of hydraulic pistons or the like but also the roller 16 in the frame 21 can be moved.

The invention relates to a pair of squeeze rollers, the invention is based on the following considerations:

Particularly for foulards and the like, in which one of the A uniform squeeze joint is only achieved cooperating rollers as loaded on a yoke 30 when the deflection of the surfaces of both rollers Gert jacket tube roller, the bending line of which is equal to the contact line by means of between.

In treatment processes for textile finishing, the bending line of the roller 10 can exactly cover There is often the need to bring goods that are fully wet when the storage distance between the control lanes mechanically, for example by nip rollers, the roller 10 is designed so that the bearings of this water. Since it has been found that it is precisely on the connection between the bending radius following for the roller Treatments are often of great importance is that the drainage extends over the web width. Since the bending radius is very large, the difference te takes place as evenly as possible so, for example, the bearing distances are so small that there is enough Colors, a completely uniform product loss is a precise approximation, if both storage distances the web width is guaranteed, it is because the de are the same and the bearings are chosen opposite who-pinch rollers with the necessary squeezing pressures 45 den.

To achieve this goal, the various pressures on the pipe 12 have already been applied. Under the most constructions of nip rollers or the effect of these forces, the roller 16 bends Pinch roller pairings have been proposed. In when employed on the roller 10 according to the through More recently, when the tube 12 of the roller 10 is pretensioned with great precision the squeezing effect arrives across the width of the fabric, bending line.

Outer casing rollers are often used, in which the casing pipe is denoted generally by 10 in the case of the pair of squeezing rollers in FIG. The distributed pressure body, such as rollers, hydraulic star-roller consists of the fixed yoke 11 and the pel and the like. Is supported against a yoke. Tubular jacket 12, which rotates by means of the bearings 15 on the yoke 11 by applying different pressure to this body. In the interior of the pipe jacket 12, the pipe jacket can be deformed and the bending line 60, the yoke 11 and the pipe jacket 12, are largely adapted to the pressure conveyor counter-roller. A complete 13 is arranged, which is used to adjust the pipe jacket by means of adjustment and thus to provide a uniform squeeze-off 12. In the figure, the web is marked with 22 but could only be reached when drawing. The length of the pipe jacket 12 is in the two of these expensive special rollers cooperate. provided example with L; designated.

The aim of the present invention is to achieve the object be released, completely even squeezing and is designed as a solid roller in the example shown to be reached across the width of the goods if only one leads, for example with an elastic covering 19.
