- --- ~ --- »-» --- rv-aww-e- ~ q--. . ., -, ..._-. «I ._._ _.1 ..- ~ ..._, ..._-.-__-.-___.._, _. ~ _ .. ., __.,. s4os4es-4 I '2 attaching a plurality of fiberglass threads formed of bundles of glass yarn formed on the carrier by means of a flame-retardant base layer of adhesive, so that the threads extend substantially parallel to each other along the longitudinal direction of the wallpaper at a distance from each other, calculated in the transverse direction of the threads, and abut with its side facing the wearer against said base layer, and externally along the threads, on the side of the same facing the wearer, apply a flame-resistant and pigmented surface layer. The invention is described below as a preferred embodiment, reference being made to the accompanying drawings, in which Fig. 1 schematically shows different steps in the manufacture of a cladding according to the invention, in Fig. 2 shows a section across a manufactured cladding, fig. Fig. 2A shows on an enlarged scale a portion of the cladding, and 7 in Fig. 3 shows a pattern image of a manufactured cladding.

From, for example, spools I or other storage rollers, which support wound glass yarn 2 of glass fiber material, the fiber yarns 2 in question are discharged, so that after any deflection around deflectors 3 in the direction of the arrows 4, from a first station I, they can be paralleled relative to each other. in the feed direction by deflection around further deflection means 5 in a second station II.

Then the wires 2 are fed in the direction of the arrow 6, after compression between, for example, rollers 7, 8, to a third station III. In this station III the fastening of wires 2 to a carrier 10 for the cladding 9 according to the invention formed in the intended formed as wallpaper is also included.

Said carrier 10 is suitably formed of fibrous material, such as paper, and may have the shape of an elongate web, which is wound up to form a roll 11, from which it can be discharged in the direction of the arrow 12 to a collecting device 13. Prior to arrival at, or in the passage of, the device 13, the carrier 10 is intended to be coated with an adhesive layer 14, which consists of adhesive, which has the ability to be flame retardant. V .M-.q -... fei a 8405463-4 and which is suitably also pigmented with the desired color.

For example, a container 15 can hold, for forming said adhesive layers in the dried and / or hardened state, blank 16 intended in the un solidified state, and which can for instance be applied to the carrier web 10 along preferably its entire one side surface 10A, by means of a roller 17, acting in said container 15 and blank 16. When deflected around a roller 18, etc. included for the web 10 and the wires 2 in the device 13, the wires 2 are applied to the base layer 14 of adhesive coated along the web 10. During the subsequent passage of a formed nip between, for example, said roller 18 and a press roller 19 cooperating therewith in the direction of the arrow 20, the threads 2 are pressed, so that they with their sides ZA facing the carrier 10 are pressed into the not yet solidified and / or or cured base layer 14, which is intended to, in addition to the purpose of serving for fastening purposes or as flame retardant for the formed wallpaper 9, suitably also provide a primer effect of the wallpaper 9, depending on whether the layer 14 is pigmented with the intended color.

Then the web 10 is allowed to dry / harden with applied threads 2, which in the example shown extend substantially parallel in relation to each other and substantially in common direction with the longitudinal direction of the web, but which of course can also have a different stretch. Drying / curing can take place in a subsequent fourth station IV, which can have a suitable number of winding rollers 21, 22, etc., around which the formed wallpaper 9 is wound, for example in a heat-emitting oven.

In a fifth and subsequent station V, along the side 2B of the wires 2 attached to the carrier 10, which are facing in the direction of the carrier 10, a flame-retardant, preferably pigmented surface layer 23 is also applied, said said outer layer 23 can be applied to the wires 2 by shaving on the layer 23, so that only the outer sides 2B of the threads or the raised portions projecting from the base layer 14 are coated with said outer layer 23, whereby color effect is achieved with the threads 2 against the background of the base layer 14. Other application procedure of external condition 23 is also possible, for example by means of a roller etc.

Thereafter, said outer layers are also allowed to dry in a suitable manner, after which the wallpaper web 9, which runs in the direction of the arrow 24, is passed to the subsequent general treatment of wallpaper, is4os4as-41, such as winding, cutting, etc.

The cladding formed by the wallpaper 9, which is suitable for attachment to walls and other surfaces of a suitable type, is made possible to be mounted on, for example, a wall in the usual way, as in conventional wallpapers, thereby making it possible to provide a flame-retardant cladding of the desired color by to “easily and quickly attach the intended wallpaper 9, which is made possible even for not fully trained persons.

According to the present invention, fiberglass yarns formed by wire bundles formed of glass yarns are attached in parallel along the wallpaper at a distance from each other, as shown in Fig. 3. Such fiberglass yarns are environmentally safe and do not cause such problems as known fiber yarns bond to each other does, for example, causes dust formation, and provides good fire safety. The threads are on one side attached to the carrier via a flame-retardant base layer of adhesive, while its other side is coated with a flame-retardant and pigmented surface layer. A thus ready-painted joint-free, flame-resistant and environmentally friendly wallpaper of fire class I is made possible by the present invention and which is made possible to be provided with a pigmentation with a colored bottom effect of the base layer.

The invention is not limited to the above-mentioned embodiment shown in the drawings, but can be varied within the scope of the appended claims, without departing from the spirit of the invention. For example, threads can be equated with strips of fiberglass material.
