A calender for treating a paper web includes a roller stack being loaded with a load on one end. The calender has at least two hard rollers each having a substantially smooth outer surface. The at least two hard rollers each have a device for heating a surface of the roller to a temperature of at least 100.degree. C. The calender also includes at least two soft rollers, wherein each of the at least two soft rollers is disposed adjacent to at least one of the at least two hard rollers to form a working nip therebetween. At least one working nip has a dwell time of the paper web passing through the working nip of at least 0.1 ms. The load on the rollers produces an average compressive stress in the at least one working nip of at least 42 N/mm.sup.2. An arithmetic mean of the numerical value of the surface temperature T, the dwell time t and the compressive stress p in all of the working nips satisfies the following relationship: a target value Zg=1.378-0.00356.multidot.T-(0.00825-5.12.multidot.10.sup.-5 T)p-�0.039+(0.188-0.00112T)p.multidot.e.sup.-0.093p !t.multidot.e.sup.-0.42lt =0.8 to 0.9.

A controlled deflection roll for use in calenders and like machines has a non-rotatable carrier for a hollow cylindrical shell the end portions of which are rotatable on bearings and the central portion of which surrounds hydraulically operated shell deforming elements. A first hydraulic circuit is provided to supply heated oil to the deforming elements, and a second hydraulic circuit serves to feed lubricant to the bearings. The two circuits are separated from each other by thermal barriers which are installed between the shell and the carrier intermediate the deforming elements and the bearings. Valves and/or flow restrictors are provided in the second circuit to vary the rate of feed of lubricant to and/or the flow of lubricant from the bearings. This renders it possible to establish a desired temperature profile along the full length of the peripheral surface of the shell.

A system of rolls for use in a calender has an end roll with a fixed carrier and a deformable hollow cylindrical shell surrounding the carrier with freedom of radial movement and defining with a neighboring roll an elongated nip for a running web of paper, textile material or the like. The end roll has a row of primary hydrostatic supporting elements disposed between the carrier and the shell adjacent the nip and a row of secondary hydrostatic supporting elements diametrically opposite the row of primary supporting elements. The bearings between the end portions of the shell and the carrier surround rings which are movable relative to the carrier radially of the shell and can be arrested in selected positions by cylinder and piston units which are connected to a source of pressurized fluid by way of shutoff valves. The areas of those surfaces of at least some primary supporting elements which are adjacent the internal surface of the shell are greater than the corresponding areas of at least some secondary supporting elements. This contributes to a reduction of friction and to a reduction of the temperature of the shell.

A device for adjusting the roller gap of superimposed rollers of a calender with upwardly and downwardly movable spindles suspended on both sides of the calender which extend through supporting means on lateral ends of roller bearings. Below each supporting means a spindle nut is adjustable relative to the pertaining supporting means. The distance between each spindle nut and the supporting means thereabove is adapted to be sensed. Each supporting means carries a feeler head of a proximity switch and a vertical guiding bar having guided thereon a marker adjustable by the respective spindle nut on the pertaining guiding bar in the longitudinal direction of the pertaining guiding bar.

The invention relates to the cargo area of an airport, having transporting paths which connect the land side and the air side of the airport and are intended for the standard loading units (ULDs), and also having interim stores for the buffer storage of the loading units prior to the cargo being assembled. In order to create storage and sorting opportunities in the immediate vicinity of the transporting paths, while being simultaneously independent of the main store, and in order to achieve flexible supply of the loading units, it is proposed for the transporting paths to be assigned vertical stores each with a plurality of storage levels which are arranged one above the other, are set up above or alongside the transporting paths and in which, with the aid of lifting means, the loading units, which can be lifted off from the transporting paths, can be stored.

A calender for treating both sides of a paper web includes hard rollers and soft rollers. Working nips are formed between the juncture of each hard roller and soft roller. The roller stack can be loaded from one end, and preferably includes six to eight rollers. A changeover nip is formed by the juncture of two soft rollers or at the transition between two stacks. When using two stacks, each stack preferably has three to five rollers. At least one working nip has a dwell time of at least 0.1 ms. A heatable roller adjacent to the working nip is heated to a surface temperature of at least 100.degree. C. The roller stack is loaded such that an average compressive stress in the working nip is greater than or equal to 42 N/mm.sup.2.

A calender roll wherein a cylindrical shell is rotatably mounted on a stationary carrier by way of bearings which are disposed in the end portions of the shell. The median portion of the shell is heated by a first heating device, and the end portions of the shell are heated by a discrete second heating device. The second heating device has channels which are provided in the end portions of the shell and/or indictive heaters which are adjacent to the exterior of the end portions of the shell. Alternatively or in addition to such expedients, the second heating device can include the bearings in the end portions of the shell; each such bearing includes or constitutes an axial or radial hydrostatic bearing which is heated by hydraulic fluid to thereby heat the respective end portion of the shell. The second heating device ensures that the effective length of the shell approximates or even matches the axial length of the shell.
