摘要： 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.

摘要： 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.

摘要： A calender for the two-sided treatment of a paper web has two similar stacks each of which has at least two soft rollers and two hard rollers. Working nips are formed between each hard and soft roller. The calender has at least one working nip wherein the dwell time (t) is at least 0.1 ms, the surface temperature (T) is at least 100.degree.C., and the load (P) on the stack creates an average compressive stress in the working nip of more than 42 N/mm.sup.2. This provides a calender that is smaller and less expensive to manufacture and operate than super-calenders of the prior art but that also affords excellent finishing results.

摘要： An apparatus and method for treating a sheet material (3) with an arrangement of rollers (6, 7), including at least one heated roller (8, 9), which defines at least one roller gap through which the sheet of material is passed and acted upon with pressure and/or elevated temperature. A housing (32) surrounds the roller arrangement (6, 7) and the treatment takes place in an environmental atmosphere, the temperature and/or humidity of which can be adjusted to a specified value. A roll of the sheet material is subjected to pretreatment to provide it with desired temperature and humidity conditions before entering the housing (32).

摘要： A method and apparatus for treating a web of paper or board applies a functional coating to the web, followed by calendaring. The functional coating is first applied without direct contact between a coating supplier and the web. Next, the web is calendered utilizing a broad nip in a shoe calendar, the shoe calendar having a shoe roller with a rotating outer cover and a squeeze roller. The shoe calendar has a shoe roller exhibiting a rotating outer cover and a squeeze roller interacting with the shoe roller.
