Abstract
The invention relates to a process for producing pipe sleeves made of mineral wool for insulating pipelines or for reducing the sound level in pipeline systems, comprising the following steps: providing a nonwoven web () made of mineral wool which is provided with an uncured binder, winding up the nonwoven web () on a winding mandrel () of a winder, curing the binder. Here, at least one reinforcing layer () is provided before the nonwoven web () runs into the winder, in such a way that during the winding the said reinforcing layer becomes a constituent part of the pipe sleeve produced as a result.
