A friction liner, for a dry friction device such as a clutch friction wheel, or a disk brake for a motor vehicle gearbox, is of flat, annular general form. It comprises a flat annular body of friction material having a cylindrical inner surface and a cylindrical outer surface. At least one annular reinforcing zone is incorporated in the body of the liner.

Friction liner for a dry friction device, a method of making such a liner, and a clutch friction wheel having such a liner

An annular friction liner, especially for use in a friction device of a motor vehicle, is made by an apparatus including a pair of adjacent conical rolls, a helical guide and a device for trimming a length of the continuous ring whereby a straight strip of friction material, having a width substantially equal to the required final width of the liner, is deformed into a continuous ring.

Apparatus for making an annular friction liner

Disclosed is a process for manufacturing a filtration device. The process includes a fibre carding procedure which forms a web. The filtration device in accordance with the invention takes the form of a web having a single layer lap.

Filtration device and process for its manufacture

A combined filter, for removing solid particles and noxious gases from air to be delivered into the cabin of a vehicle, as part of a ventilating, heating and/or air conditioning system, comprises two layers of a non-woven tissue such as polypropylene, between which are deposited activated carbon granules. The two layers of non-woven tissue are interleaved at least partially, so as to trap the granules between them.
