Problems solved by technology

Such a method is not entirely satisfactory because it requires the use of relatively bulky equipment and because the compressive strength of the annular (or tubular) member produced is inferior to that of the starting material

Embodiment Construction

[0034]The apparatus shown in Fig. 7 is used to implement the punching method of the present invention. This punching method will be described in detail below. The apparatus comprises a device 21 for stepwise advancing a strip 22 of coated fibrous material, such as mineral wool or vegetable fibers, which extend in the longitudinal direction A of the strip. In addition, the device also includes a platen 24 in which a piercing punch 27 is mounted in a hole 25 of the platen 24 . The piercing punch 27 is tubular and its length x is 80% to 500%, preferably 100% to 350%, especially 200% to 300%, of the thickness t of the strip 22. The back pressure plate 210 may be provided with a hole 28 , see FIG. 9 , and the back pressure plate 210 is arranged opposite to the pressure plate 24 . The length of the piercing punch 27 is such that when the piercing punch has been pressed into the strip, the punched-out components are pushed backwards and outwards through the inner channel of the pie...

Abstract

The invention relates to an assembly comprising on the one hand a compressed tubular mineral wool felt element (3) and on the other hand at least one retaining means (5) for maintaining the compressed state of the felt. The retaining means (5) may be a film surrounding the felt member on its cylindrical surface. This assembly can be used as an isolation bushing in a conveyor line. The invention also relates to a method for producing annular components by punching holes, where the starting material is a coated fiber material, such as a strip of quenched mineral wool. At least one punching tool in the form of a punch is mounted on the pressure plate and is pressed through the strip and then withdrawn.

Description

technical field [0001] The present invention relates to the isolation of conveying lines, such as piping systems, especially in the field of thermal or even acoustic isolation, which convey or enclose a fluid at a temperature different from its ambient temperature. Especially for limiting heat exchange between transfer lines and their environment. [0002] The present invention relates to a method of producing components, such as annular (in fact tubular) components, by punching, starting from coated (generally by a network-like binder) fiber material, such as quenched ( In the heat quenching sense) nonwoven strips (that is to say felts) of mineral wool, using at least one punching (or stamping) tool in the form of a piercing punch mounted in a press plate, The piercing punch is pressed through the nonwoven strip of coated fiber material and then pulled out. Background technique [0003] We study the means of thermal insulation of transmission lines regardless of their dia...
