Abstract: A heatable roller suitable for a machine for producing and/or upgrading a web of material, in particular a fibrous material web such as a paper, paperboard or tissue web. The roller has a main element with a metallic and cylindrical roller wall which is heatable by suitable means and on the radially outer side of which there is, at least in sections, a coating. When the roller is used as intended, the coating provides a web contact side which can be brought into contact with the web of material. The coating includes, or is formed by, at least one metallic or metal-carbidic layer with a first layer component providing a matrix and a second layer component distributed in the matrix. The first layer component has a higher abrasion resistance than the second layer component and the second layer component has a greater thermal conductivity than the first layer component.

Abstract: A roll for use in a machine for producing and/or further processing a fibrous web, such as a paper, paperboard, or tissue web, includes a roll cover having at least some sections or regions formed of a metal material and a coating formed on the roll cover. The coating is formed of a metal, ceramic and/or cermet material, or at least some sections or regions of the coating include one of those materials. An alloy region is situated between the roll cover and the coating.

Abstract: A blade for treating fibrous nonwoven webs having a base body and a coating covering at least a part of the surface of the base body. The coating forms at least that part of the blade surface which is provided to come into contact with the fibrous nonwoven web. At the contact surface, the coating has an open-pored material, the pores of which are filled at least partly with a polymer.

Abstract: A combination of a press felt with a pressure and/or suction roll covering for a papermaking machine, including a porous press felt with a carrier structure. The pressure or suction roll covering having a circumferential groove surface structure having a groove width in the range of 0.5 mm to 1.5 mm, a distance between grooves in the range of 1.5 to 2.5 mm and a groove depth in the range of 1.5 mm to 4 mm. A percentage of an open surface relative to an overall surface of the pressure roll covering is in a range of 20% to 50%. The suction roll covering additionally having an arrangement of holes with a plurality of suction holes completely penetrating through the suction roll covering, whereby a percentage of an open surface in relation to an overall surface of the suction roll covering is in a range of 30% to 50%.

Abstract: A fuse link, especially for low voltage, high-breaking-capacity fuses, includes at least one fusible conductor having a soldering substance in a solder depot of a carrier, the solder being tin-based and the carrier being copper-based. The solder contains a tin alloy as an active substance, the tin alloy having two other constituents. The first constituent, which is the larger of the two in weight percent but which is smaller in weight percent than the proportion of the base substance tin, is selected for lowering the fusion temperature of the solder. The second constituent, which is the smaller of the two in weight percent, is a substance which does not dissolve in tin. Crystal nuclei are formed when said substance is cooled from the liquid state to the solid state, creating a fine structure and preventing the structure from becoming coarse under a load.
