Abstract
The invention relates to an assembly comprising, on the one hand, a tubular compressed mineral wool felt element and, on the other hand, at least one means of maintaining the compression state of the said felt. The maintaining means may be a film surrounding the felt element on its cylinder-shaped surface. The assembly may be used as an insulating pipe section for pipework. The invention also relates to a method of producing annular elements, by way of punching, where the starting material is a web of bonded fibrous material, such as tempered mineral wool. A punching tool in the form of at least one punch knife which is mounted on a press plate is pressed through the web then pulled out again.
