Estimating the term…
A roll arrangement for the non-deforming treatment of moving web-type or strip-type products. The arrangement includes at least two rotatable rolls which are adjustable radially relative to each other. The arrangement is used, for example, for drying one or both surfaces of the product. The rolls are axially adjustable in opposite direction and each roll has slightly S-shaped or bottle-shaped contour over the entire length of the roll body, in such a way that the contours of two rolls arranged on both sides of a roll gap complement each other only in a certain relative axial position of these rolls. In other axial positions of the rolls, the roll gap becomes narrower either in the center or at the ends of the rolls, so that a uniform pressing action or other uniform non-deforming treatment of the product is possible over the entire width of the product independently of the bending of the rolls and/or deviations from the plane-parallelism of the surfaces of the product.
In a method for the treatment of moving flat woven or mesh material of fiber, felt or textile by means of a roll arrangement including at least two rotatable treatment rolls which are adjustable radially and axially relative to each other, the rolls including roll bodies, each roll having a slightly S-shaped or bottle-shaped contour over the entire length of the roll body in axial direction thereof, wherein the contours of two rolls arranged adjacent each other and defining a roll gap therebetween each other only in a certain relative position of the rolls, the improvement comprising moving the material through the roll gap under low pressure such that the contour or shape of the products is essentially not permanently changed by the rolls.
