Roll with a Rubber or Rubber-Like Sheath for Coatin~
or Other Applicator Devices The present invention relates to a roll for use in a substrate (e.g. paper or the like) applicator.
Rolls of this type are used in many areas where paper or cardboard are coated in a pressure gap formed between two rolls. In general, the amount of coating material applied is small (low specific weight per unit area). The coating materials usually contain a considerable amount of water as solvent.
In the case of rolls which are covered by a plastic, such as polyurethane or polyamide, there is the danger that damage can occur through hydrolysis, especially to the bonding layer, which forms the joint between the plastic sheath and the rnetal core of the roll. In addition, the plastic sheath can soften, which leads to a change in its hardness and to a loss of strength. This, of course, also considerably reduces the service life of a roll of ~is type, which means that it will have to be replaced prematurely.
In the past, it has been proposed to utilize heatable rolls. Although a wide variety of designs for heatable rolls is known, these are rolls of pure metal, which must have a high surface temperature for use, for example, in calenders, one of the main areas of application.

Accordingly, the present invention provides an applicator for applying a spreading or coating compound to a substrate, the applicator comprising a coating roll or mating roll consisting of a core and a sheath, the core being of metal, preferably steel, and the sheath being of rubber or a rubber-like material, characterized in that the metal core (1) has a temperature at least 0.1 K higher than that of the sheath (2), at least in the area of the boundary surface between the core and the sheath.
Typically, the s~reading or coa~ng composition is forlTIulated on the basis of pigments or starch to be applied to a subst~ate such as paper or cardboard.

While not wishing to be bound by any particular theory or mode of operation, it is believed that although some water molecules still arrive at the adhesion layer of the roll covering (plastic sheath), the amount arriving there is not large enough to form "moisture nests". Thus, in the present roll, the small amount of water reaching the adhesive layer cannot exert a substantially damaging effect in the roll.
The present roll can be used advantageously in a coating system with two press rolls according, for example, to U.S. Patent No. 4,848,268 or with at least one mating roll of a feed device for the coating compound, such as, for examp]e, that according to U.S. Patent 4,250,211, this mating roll guiding the web of product, e.g., especially a web of paper or cardboard, around a certain wrap angle.
