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 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.

2. The method according to claim 1 wherein the separation of the two parts of the strip into two comb-like members comprises a first stage in which the strip is punched or cut along a sinuous line, but with interruptions which constitute bridges of unpunched or cut material which maintain the two edges of the strip together, and a second stage in which the edges of the strip are pulled apart to separate them from one another with fracture of the bridges.

3. The method according to claim 2 wherein, in the first stage, the strip is uncoiled, punched or cut and then re-coiled.

4. The method according to claim 1 wherein, during or following the separation of the strip into two portions, the strip is passed through a folding or creasing mechanism which acts to provide a fold or crease between the edge of the emerging comb-like strip and a location near or at the line where the individual teeth or prongs join the strip.

5. The method according to claim 4 and including the step of impressing dents or punching holes in the edge of each separated portion to act as a guide for nails used to affix the strip in place.

6. The method according to claim 1 wherein, in order to facilitate folding or bending of the edges of the strip, a number of cuts or slots extending parallel to the side edges of the strip are punched in the material of the strip.

7. The method according to claim 1 wherein the comb-like structure is provided with an overlay of flexible material across the gaps between the individual teeth to enable the comb-like strip better to resist penetration from small flying insects.

8. 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.

9. The method according to claim 8 wherein the comb-like structure is provided with an overlay of flexible material across the gaps between the individual teeth to enable the comb-like strip better to 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.

11. The method according to claim 10 wherein the width and spacing of the transverse slots are such that the width of the teeth in the comb-like structure is greater than the gaps between the teeth.

12. The method according to claim 10 wherein the comb-like structure is provided with an overlay of flexible material across the gaps between the individual teeth to enable the comb-like strip better to resist penetration from small flying insects.

13. The method according to claim 12 which includes applying a highly elastic fabric, netting or loosely flocked or felted material to one side of the comb or impaled such a material on the teeth of the comb.
