Abstract: Cylindrical objects such as rolled coils are frequently stored supported on rows of supporting members which rows have along their length a regularly repeating hill and valley profile. With increasing coil size and weight the supporting members tend increasingly to become damaged and stacks of several layers of coils become less stable. To ameliorate these problems the supporting members are made of a resiliently deformable material such as a low density polyethylene and are so shaped when not deformed that the hill and valley profile has a series of upwardly projecting ridges, sloping regions extending downwardly away from each side of each ridge, and substantially horizontal regions between the sloping regions. Preferably each supporting member has one centrally disposed ridge, a sloping region on each side of the ridge, and half of a horizontal region at each end.

Abstract: A method of forming a composite extrusion is disclosed wherein a main body portion (1) of the extrusion is first extruded from a thermosetting material, this body portion then being heated so as at least partly to cure it, the main body portion then being passed at high temperature through a further extruder where a thermoplastics material (8) is extruded onto one or more surfaces of the main body portion (1), the subsequent composite extrusion then being cooled and formed into its final shape. It is important that the combining step be undertaken at a temperatue high enough to cause the thermoplastics material to bond to the thermosetting material and while it is simplest for the thermoplastics material to be on an outer surface of the composite extrusion, it is possible for it to be located within the thermosetting material by extruding the thermosetting material in an "opened out" state and then after extruding the thermoplastics and while the extrusion is still hot, folding in edge regions of the main body to overlie the thermoplastics material and bond thereto. The thermoplastics material may be of a special colour, may be embossed, and if it is located within the thermosetting material in the end product, may be stiffer than the latter. The invention also extends to the extrusions themselves.

Date Aug. 5, 1993In order to be able to consolidate mineral fibers without binder, such as in particular glass wool into a needle-felt by needle-punching, an agent as a needling aid which comprises a thixotropizing additive having a relatively low flow viscosity during needling and thus allows to effectively support the needling process, is added to the mineral fibers. At rest, this thixotropizing additive however has an extremely high viscosity, whereby the needle-punched felt obtains good strength. In particular, for needling rock wool, suppler textile fibers are moreover added which contribute to improved mutual interlocking of the fibers, in particular in the case of mineral fibers such as basalt fibers, which can only with difficulty be interlocked by needling. A corresponding processing aid furthermore proves advantageous in the production of a crimped mat from a laminar mat, as the drastically weakened resistance against further shifting makes it possible to reorient the fibers in the crimping zone, gently and to a large degree, without the application of excessively large forces.
