Cover for ironer rollers or the like layered helically, wound Metal fiber ribbons

The invention relates to a covering ^ for Mangle rollers or the like, consisting of metal fiber strips made of crimped metal fibers, which are layered are helically wound on the ironer roller and consists in that the Metal fiber ribbons are interspersed with smoothly cut, non-crimped metal fibers.

It is known to mangle with metal fiber ribbons winding, whereby the good properties and thus the advantage of these metal fiber layers or the metal fiber base lies in that it is good

air and vapor permeable, hit zeb constantly, is thermally conductive and point elastic. ;

The crimping of the metal fibers produced by a "A certain machining process is achieved", brings about the elasticity of the support of the ironer roller. However, these known metal fiber tapes applied to mangles have the considerable The disadvantage is that the crimped metal fibers are caused by the circumferential forces generated by the contact pressure be elongated, whereby the elasticity of the covering is reduced. Furthermore, a Lengthening of the strands and thus a reduction in the thickness of the lining or the entire end diameter of the stirrup roller, which overall affects the ironing effect considerably.

Attempts have been made to stop the circumferential forces by placing the metal fiber strands in asbestos hoses inserts or applies these metal fiber strands to carrier tapes. However, this affects disadvantageous, in particular on the ironing effect, there the metal fiber strands or metal fiber layers through foreign materials, which also do not have the elasticity of the metal fibers are interrupted and separated and isolated from one another. This will the heat distribution is interrupted, which cannot be as beneficial as with a pure one, not Metal fiber covering interrupted by foreign bodies.

The present invention has the task of avoiding these disadvantages by an elongation the metal fiber strands is avoided in that the highly elastic, crimped into the strand Metal fibers a strand of non-crimped, smooth-cut metal fibers is inserted. Because of the lack of crimp, this strand has no possibility of elongation and works counteracts the circumferential forces that occur, so that elongation of the metal fibers is avoided and these remain highly elastic.

Further features of the invention emerge from the following description of an exemplary embodiment in conjunction with the drawings and the claim.

It show, in schematic sketches,

FIG. 2 shows a section of the metal fiber band on an enlarged scale with the crimped ones Metal fibers and the inlaid smooth metal fibers.

In FIG. 1, a metal fiber band 2 is wound helically onto a mangle roller 1, with the Metal fiber tape 2 consists of crimped metal fibers 3 and non-crimped smooth metal fibers 4. About the metal fiber tape 2 is a protection
