Abstract

The present invention is directed roof edge seal and barrier devices and their method of manufacture. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier comprises stamping or cutting an elongate strip of material along a sinuous path located between the edges of the strip and then separating the strip into two portions, each of which consists of a fixing edge corresponding to the edge of the original strip from which project a series of teeth or prongs forming a comb structure.

Claims

1. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier which comprises stamping or cutting an original elongated strip of material along a sinuous path located between the edges of the original elongated strip and then separating the original elongated strip along the sinuous path into two portions by pulling the two portions apart, wherein each of the two portions consists of a fixing edge corresponding to the edge of the original strip, a side portion extending a distance from the fixing edge, and a series of teeth or prongs extending from the side portion and forming a comb structure wherein each individual tooth or prong in the series of teeth or prongs is spaced apart such that a gap is present between each individual tooth or prong.

2. The method according to claim 1 wherein the original elongated strip is stamped or cut along a sinuous path that includes interruptions of unstamped or uncut material and separating the original elongated strip into the two portions by fracturing the interruptions as the two portions are pulled apart.

3. The method according to claim 2 wherein the original elongated strip is uncoiled prior to being stamped or cut and then re-coiled once the original elongated strip is stamped or cut.

4. The method according to claim 1 wherein, during the separation of the original elongated strip along the sinuous path into two portions, the original elongated strip is passed through a folding or creasing mechanism which acts to provide a fold or crease in the side portion of one or both of the two portions at a location near or at where the series of teeth or prongs extends from the side portion.

5. The method according to claim 4 further comprising the step of impressing dents or punching holes in the side portion of one or both of the two portions to act as a guide for nails.

6. The method according to claim 1 further comprising stamping or cutting a number of cuts or slots extending parallel to the edges of the original elongated strip, in order to facilitate folding or creasing one or both of the two portions.

7. The method according to claim 1 wherein the comb structure is provided with an overlay of flexible material across the gaps between each tooth or prong of the series of teeth or prongs to enable the comb structure to better resist penetration from small flying insects.

8. The method according to claim 1 wherein, following the separation of the original elongated strip along the sinuous path into two portions, one or both of the two portions is passed through a folding or creasing mechanism which acts to provide a fold or crease in the side portion of one or both of the two portions at a location near or at where the series of teeth or prongs extends from the side portion.

9. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier which comprises punching a strip of material with a plurality of transverse slots and subsequently parting the strip to provide two strips, one or both having a comb-like set of teeth on it such that there is a gap between the individual teeth of the comb-like set of teeth and wherein the comb-like set of teeth is provided with an overlay of flexible material across the gaps between the individual teeth to enable the comb-like set of teeth to better resist penetration from small flying insects.

10. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier which comprises punching a plurality of transverse slots in a strip of material and subsequently removing one edge of the strip to produce a comb-like structure having a series of teeth spaced apart such that a gap is present between each tooth and wherein the transverse slots in the strip of material are sized and spaced such that in the comb-like structure, the series of teeth are disposed along a length of the comb-like structure such that the teeth occupy a larger portion of the length of the comb-like structure than the gaps between the teeth.

11. The method according to claim 10 wherein the comb-like structure is provided with an overlay of flexible material across the gaps present between each tooth in the series of teeth to enable the comb-like structure to better resist penetration from small flying insects.

12. The method according to claim 11 which includes applying a highly elastic fabric, netting or loosely flocked or felted material to one side of the comb-like structure or impaling such a material on the series of teeth of the comb-like structure.
