Description

8201370-7 Detta uppnås enligt föreliggande uppfinning därigenom att folien är delad på längden i två remsor, av vilka åtminstone den folieremsa som ligger närmast tungorna är en avrivningsfolie, att de två folieremsorna överlappar varandra vid sina sammanfal- lande längsgående kanter, och att klisterfältet vid shingelele- mentets bakkant består av värmekänslig asfalt, medan klisterfäl- ten för tungorna är både värme- och tryckkänsliga. This is achieved according to the present invention in that the foil is divided lengthwise into two strips, of which at least the foil strip closest to the tongues is a tear-off foil, that the two foil strips overlap each other at their coincident longitudinal edges, and that the adhesive field at the trailing edge of the shingle element consists of heat-sensitive asphalt, while the adhesive fields for the tongues are both heat- and pressure-sensitive.

V En fördelaktig utföringsform utmärker sig av klisterfältet vid bakkanten och klisterfälten för tungorna går över i varandra, så att ett gemensamt klisterfält med tandad kant bildas.V An advantageous embodiment is characterized by the adhesive field at the trailing edge and the adhesive fields for the tongues merge into each other, so that a common adhesive field with a toothed edge is formed.

Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritning, på vilken fig 1 visar shingelelementet enligt uppfinningen sett ovanifrån, fig 2 visar shingelelementet sett underifrån, fig 3 visar shingelement enligt uppfinningen lagda på ett första sätt, och fig H visar shingelelement enligt uppfinningen lagda på ett andra sätt.The invention is described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows the shingle element according to the invention seen from above, Fig. 2 shows the shingle element seen from below, Fig. 3 shows shingle elements according to the invention laid in a first way, and Fig. H shows shingle elements according to the invention laid on a other ways.

Shingelelementet 1 består på vanligt sätt av en s k rygg 2 samt tungor 3. Längs bakkanten H av ryggen 2 är på shingelelementets översida anordnat ett sammanhängande klisterfält 5 av värmekänslig asfalt. På det ställe där ändarna av tungorna på ovanpåliggande element placeras är anordnade klisterfält 6 som består av värme- och tryckkänslig asfalt.The shingle element 1 usually consists of a so-called ridge 2 and tongues 3. Along the rear edge H of the ridge 2, a continuous adhesive field 5 of heat-sensitive asphalt is arranged on the upper side of the shingle element. At the place where the ends of the tongues are placed on top of the elements, adhesive panels 6 are arranged which consist of heat- and pressure-sensitive asphalt.

Tungornas översida och den del av ryggen som är synlig på det färdiga taket är på vanligt sätt bestrött med ett relativt grovt strömaterial. Shingelelementets 1 undersida har ett längs- gående klisterfält 7, som är täckt med en plastfolie som är delad i två remsor 8 och 9. Remsorna har en sådan bredd att de över- lappar varandra vid en mittöverlappning 10. Såsom framgår av det ovanstående och även syns på ritningen, kommer folieremsorna 8 och 9 att fullständigt täcka klisterfälten 5 och 6 när shingelelementen staplas på varandra med det ena shingelelementets undersida mot det nedanförliggande shingelelementets översida. Sålunda sker ingen hopklisting i packen.The upper side of the tongues and the part of the back that is visible on the finished roof is usually sprinkled with a relatively coarse spreading material. The underside of the shingle element 1 has a longitudinal adhesive field 7, which is covered with a plastic foil which is divided into two strips 8 and 9. The strips have such a width that they overlap each other at a central overlap 10. As can be seen from the above and also As can be seen in the drawing, the foil strips 8 and 9 will completely cover the adhesive fields 5 and 6 when the shingle elements are stacked on top of each other with the underside of one shingle element facing the upper side of the shingle element below. Thus, no gluing takes place in the package.

Om shingelelementen enligt föreliggande uppfinning skall läggas i ett mot vinden oskyddat område, placeras ett shingelele- ment 1 på en färdiglagd rad av shingelelement utan att remsornaIf the shingle elements according to the present invention are to be laid in an area protected from the wind, a shingle element 1 is placed on a completed row of shingle elements without the strips

Claims

8201570-7 3 8 and 9 are removed. The shingle tongues 3 will lie on top of the adhesive fields 6 with heat and pressure sensitive, asphalt, and fields 5 with heat sensitive asphalt, and will stick so as to prevent the tongues from inflating. If shingle is to be laid on a roof in an area with rainfall, the strip 9 is removed before the shingle element 1 is laid on a previously laid row of shingle elements. The lower part of the adhesive field 7 on the back of the shingle element 1 will then lie against the adhesive field 5 on the upper side of the shingle elements below, and a tight seal is obtained at a trailing edge of a shingle row which will prevent water penetration. It is thus desired to be able to perform a labor-saving roofing in areas without driving rain by keeping the strips 8 and 9 on the back of the shingle elements. In rainfall areas, you can get a complete seal of the shingle coating by pulling off a strip 9 and you get a seal of the roof asphalt against asphalt. P a t e n t k r a v

Device at shingle element (1) for roofing, where a sticky field is arranged on the upper side of the element (1) for attaching the shingle element on top, which sticky field forms a continuous sticky field (5) at the rear edge (4) of the element, and where the back is provided with a continuous adhesive field covering the entire back of the element except for the tongues, which field is covered with a foil to prevent the individual elements from sticking together in a stack, characterized in that the foil is divided lengthwise into two strips (8, 9) , of which at least the foil strip (9) closest to the tongues (3) is a tear-off foil, that the two foil strips (8, 9) overlap each other at their coincident longitudinal edges (10), and that the adhesive field (5) at the shingle element rear edge (4) consists of heat-sensitive asphalt, while the adhesive fields (6) for the tongues (3) are both heat- and pressure-sensitive.

Device according to claim 1, characterized in that the adhesive field (5) at the trailing edge and the adhesive fields (6) of the tongues (3) merge into each other so that a common adhesive field is formed.
