Problems solved by technology

[0015] However, the elastomeric layer obtained by this method is not uniform and thicker than desired
This means excessive consumption of elastomer and imprecise application of elastomer

Embodiment Construction

[0059] First refer to figure 1 A pad printer for depositing elastomers on a sleeve of the present invention is described.

[0060] In this embodiment, the method is applied to a tubular fabric kit 2 .

[0061]By way of non-limiting example, this sheath 2 is a fabric sheath knitted from multifilaments of glass fibers impregnated with an acrylic solution containing graphite. Thus, the sheath 2 is flexible and can be crushed.

[0062] Of course, the sleeve 2 can also be manufactured from other materials, such as eg silicon dioxide, ceramics or polymers. In the case of a textile sheath, the sheath can for example consist of knitted, woven or braided multifilaments or monofilaments.

[0063] The flattened kit 2 is transported along the pad printing machine 1 by standard transport means 10 such as, for example, a series of driven rollers.

[0064] In this embodiment, the pad printing machine 1 comprises two pad printing modules 3 , 4 . Each pad printing module 3,4 all includes ...

Abstract

The invention relates to a method for applying an elastomer on a sheath (2) that comprises the step of applying by pad printing an elastomer layer on a portion (20) of the sheath (2). A pad printing machine (1) is also provided for implementing said method. The invention can particularly be used for textile sheath used in the protection of exhaust-gas circulation pipes in an automobile.

Description

technical field [0001] The invention relates to a method of applying an elastomer to a sheath. [0002] The invention also relates to a tampographie suitable for carrying out the method. [0003] Furthermore, the invention relates to a protective sheath, in particular a sheath of fabric (ie a sheath of interwoven filaments) covered with an elastomeric layer obtained by this method and cut to length. [0004] In particular, the invention applies to textile covers used to protect exhaust gas gratings (EGR) in motor vehicles. Background technique [0005] These fabric sets, usually knitted sets, are obtained by cold cutting very long fabric sets (often up to several meters) into longitudinal sections of predetermined length. [0006] When the fabric kit is cut to length, the ends of the kit flare and this flare is accentuated by the action. [0007] Thus, when installed around a pipe or pipe, the sleeve deforms at the ends and loses its protective properties. [0008] Relat...
