Embodiment Construction

[0036] figure 1 A side view of a winding machine 1 is shown in a highly schematic manner, on which a sleeve 10 according to a first embodiment is produced (cf. figure 2 ). The winding machine 1 has a winding mandrel 2 , onto which a nonwoven web 11 made of mineral wool is wound up in an inherently conventional manner, the nonwoven web 11 being supplied by a first supply belt 3 .

[0037] In the shown figure, the nonwoven web 11 has been substantially wound on the winding mandrel 2, and the inner reinforcement layer 12 has been placed on the winding mandrel 2 before starting the winding operation, so that during the winding operation , the reinforcing layer becomes an integral part of the sleeve 10 to be produced.

[0038] Furthermore, the winder 1 comprises a second supply belt 4, via which the outer reinforcing layer 13 can be supplied in such a way that its front end partially overlaps the end of the nonwoven web 11 so that it is also wound into rolls. As a result of th...

Abstract

The invention relates to a method for producing pipe sleeves made of mineral wool for insulating pipes or for reducing sound levels in piping systems, the method comprising the steps of: providing A non-woven web (11), the non-woven web is provided with an unhardened binder; the non-woven web (11) is wound on the winding mandrel (2) of the winding machine; the adhesive is hardened. At least one reinforcement layer (12, 13) is provided before the nonwoven web (11) enters the winder, so that during winding the reinforcement layer becomes an integral part of the resulting sleeve. The invention also relates to a sleeve comprising a wound nonwoven web made of mineral wool with a hardened binder and at least one reinforcing layer. Thus, the sleeves can be produced in a cost-effective manner with less labor, and the sleeves can be assembled, firstly, with improved mechanical properties, and/or secondly with virtually unchanged mechanical properties compared to conventional sleeves but with Lower bulk density.

Description

technical field [0001] The invention relates to a method for producing a pipe sleeve from mineral wool according to the preamble of claim 1, and also to a pipe sleeve comprising a coiled nonwoven web made of mineral wool with a hardened binder (nonwoven web). Background technique [0002] Sleeves of this type are frequently used, for example, in heating and water supply lines to insulate pipes so that energy losses are minimized. The insulation of such sleeves is usually produced by winding a nonwoven web made of mineral wool on a mandrel of a winder and, as described in DE 35 36 174 C1, can have an additional thin metal out-of-board stackup. The compressive strength of the sleeve, in particular in the radial direction, can conventionally be improved by means of this laminate, which is generally a thin aluminum sheet. In addition, the metal laminate also provides trickleguard against any loose fibrous material that may be present in the sleeve. [0003] While such conven...
