Aug. 28, 1962 v. APPENZELLER PRESSURE APPLYING ROLLERS Filed May 31. 1960 FIG] In en far MIL ilk 77W Alvin/251.461?
3,5,8Z9 Patented Aug. 28, 1962 3,050,829 PRESSURE APPLYING RGLLERS Valentin Appenzeller, Kreield, Germany, assignor, by mesne assignment, to Eduard Kusters, lviaschinenfahrik, Kreteld, Germany Filed May 31, 1960, Ser. No. 32,773 Claims priority, application Germany Apr. 2, 1969 2 Claims. (Cl. 29-113) This invention relates to improvements in rollers for the pressure treatment of material webs such as the smoothing and embossing of paper and similar material, for the squeezing out of moisture from textiles, for calendering for the drawing of sheets of rubber, synthetic material, or the like as well as for other pressing operations, of the type comprising a drum or tubelike hollow body forming the periphery of the roller and adapted for rotation and a stationary core located therein for taking the load wherein on the side turned towards the efiective part of the core a longitudinal chamber is provided for receiving a fluid pressure medium acting on the interior of the hollow body and on the other side of the core i.e. the side turned away from the efiective part a second longitudinal chamber is also provided which is adapted to receive a fluid pressure medium.
Rollers of the aforementioned type are already known in which between the hollow body forming the roller periphery and the core an intermediate space or gap is left on all sides and the gap is divided by longitudinal plates into a longitudinal chamber lying on the side turned towards the efiective part and a longitudinal chamber lying on the side turned away from the eiiective part. In the longitudinal chamber located on the side of the efiective part of the hollow body there is when the roller is working a fluid pressure medium, for example, pressure liquid. The flow of the pressure medium can be reversed from the inlet to this longitudinal chamber to the inlet to the longitudinal chamber located on the side turned away from the effective part of the hollow body. Such a reversal is eflected when the hollow body forming the periphery of the roller is to be raised opposite the eifective part.
According to the invention the chambers are provided in a stationary i.e. nonrotatable hollow body surrounding the core and securely held against rotation and the hollow body forming the periphery of the roller is rotatably mounted on this hollow body. Such arrangement gives besides the simple possibility of lifting the hollow body forming the periphery of the roller opposite the effective part by reversing the flow of pressure medium, the further advantage that the tightness of the longitudinal chambers remains uninfluenced by the rotation of the hollow body forming the roller periphery and the longitudinal chamber can be formed in a simple manner.
The longitudinal chambers are preferably formed by inflatable bodies, for example, tubelike structures which are arranged between the hollow body surrounding the core and the core.
The mounting of the hollow body forming the periphery of the roller on the hollow body containing the longitudinal chambers is suitably effected by bearings arranged at difierent positions along its length. Hereby in known manner the arrangement of the bearings may, for example, be such that the hollow body forming the periphery of the roller is mounted only at two positions along its length.
The accompanying illustrate diagrammatically one embodiment of the invention. In these drawings: FIG. 1 is a longitudinal section through the roller the counter roller being also indicated and FIG. 2 is a section through the roller.
In the embodiment illustrated the stationary core is indicated at 1. It may be of any cross section being shown circular in cross section. Its ends are mounted in bearings which can be adjusted in height in any suitable manner.
The core 1 is surrounded by a stationary tubelike hollow body 2 which leaves an annular space 3 between it and the core. In the space 3 on the side turned towards the counter roller 3 as an effective part between the core 1 and the hollow body 2 is arranged an inflatable body 4. On the side turned away from the effective part there is arranged likewise between the core 1 and the hollow body 2 an inflatable body 5'. These inflatable bodies formlongitudinal chambers and extend over substantially the whole length of the hollow body 2. The inflated bodies embrace the core only over the top and bottom and are separated from one another on each side thereof.
The hollow body 6 forming the periphery of the roller is rotatably mounted on the hollow body 2. The mounting is efiected by the bearings 7 arranged annularly of which two are for example provided which are shown in full lines. There may also be provided an intermediate hearing or bearings, as shown in broken lines.
The inflatable body 4 turned towards the effective part is, when the roller is working, filled with a fluid pressure medium, for example, pressure liquid or compressed air which is led into the inflatable body from a source, not shown. If the hollow body 6 forming the periphery of the roller is to be raised or lifted towards the counter roller 8 then fluid pressure medium is supplied to the inflatable body 4 on the side toward the effective part and means may be provided in the inflatable body 5 to allow of the escape of the pressure medium therefrom. It is not necessary for a fluid pressure medium of the same kind to be used for both inflatable bodies. Thus, for example, compressed air rnay be used for the inflatable body 5 and pressure liquid for the inflatable body 4 or vice versa.
The counter roller 8 may be of the same construction as the roller 7.
I claim:
1. A roller for the pressure treatment of strips of material comprising a rigid cylindrical tubular hollow element having a continuous peripheral surface adapted to rotate, said rotatable element forming the operative periphery of the roller, a rigid cylindrical tubular nonrotatable hollow element of invariable cross section, upon which the aforesaid rotary peripheral element is supported and upon which the aforesaid hollow element is able to rotate; and a nonrotatable core, inside the stationary hollow element, with ends forming bearing journals, the core having an outer diameter smaller than the inner diameter of the stationary holiow element; in combination with one tubular element which can be inflated on each side of a plane running through the axis of the core and the parallel longitudinal contact line of the outer hollow element in the gap between the stationary core and the stationary hollow element surrounding it.
2. A roller in accordance with claim 1, characterized in that there are annular bearings disposed, in the axial direction of the nonrotatable hollow element and at a distance from one another, between the outer rigid rotatable cylindrical peripheral hollow element and the rigid nonrotatable inner cylindrical tubular element that supports the former; whereby the former is able to rotate.
