Definitions

  • This invention relates to the production of double-layer cardboard roofs.
  • the upper layer to be pressed onto the adhesive is tight and perfectly flat when unrolled and completely covers at rst in a level manner all elevations and depressions, so that' air spaces in the depressions of the first layer are covered also. Owing to the action of the sun, the air in these hollow spaces considerably' expands and enlarges and increases the height of these spaces by separating the two cardboard layers at the points where they are united by the adhesive. 'I'his process constitutes the rst destruction of the rooting. The upper layer increasingly becomes uneven by the formation of cockles.
  • the invention eliminates the drawbacks mentioned by employing in the production of doublelayer pasted cardboard roofs webs comprising two standard cardboard layers pasted together by factory methods.
  • the layers are staggered relative to one another so as to provide a narrow strip free from adhesive.
  • the method of laying these webs consists in 40 overlapping the lower layers of two consecutive webs, securing'them by nailing through the nonadhesive strip to the support and uniting the projecting strip of the top layer with the adjacent one by pasting.
  • the layers are mechanically pressed together, so
  • the two layers a and b are mechanically pasted together and are staggered relative to one another in such manner that the rst layer projects beyond the second and, at the opposite edges, the second beyond the rst to the extent of a narrow strip a1, b1. These strips are free from adhesive.
  • Parallel to the strip a1 a second nonadhesive strip s extends between the two layers which are preferably diagonally displaced to pro- Vide a projecting non-adhesive strip on both the long and cross sides.
  • the method of laying the mechanically prepared webs is as follows:
  • the two webs A and B each consist of two layers of standard cardboard pasted together and are superposed so that the lower layer b of the web B lies on the strip b1 of the web A, and both are nailed to the roof boarding c while the strips al, s 'of the web B are raised. Then the strips a1, s of the web B are provided with an adhesive and pasted across and beyond the nailing onto the respective portion of the webA.
  • a roof covering made up of unit sections, each comprising two layers of cardboard or the like of substantially uniform surface area and disposed one upon the other in oset edge relation, whereby a margin of the lower layer projects beyOnd the upper layer at one edge and a similar margin of the upper layei projects beyond the proximate edge of the lower layerat the opposite edge, the contacting faces of the layers being cemented together except for ⁇ a marginal area of the lower layer at the edge adjacent the projecting margin of the upper layer, the sections being applied for roong purposes with the uncemented margin of the lower layer resting upon overlle, protect and sed the securing means md tooverlle-andbesecuredtotheupperlayer materially beyond the edle of the upper layer of thepreoeding section, whereby the roo! n s whole presents s double thickness of material throughout its full area and a. third thickness overlying and sealed to the roof covering in both glctions beyond the meeting edges of adjacent PHILIPP SATI'IG
