This invention provides suspension fabric product, methods of making such product, and methods of installing such product, in fall protection systems used in metal building construction. The fabric product is presented Z-folded on a core, with essentially all surface air removed, and wrapped in a protective plastic wrapping which extends into the roll alongside outer layers of the roll of fabric. Essentially all surface air is removed from the Z-folded fabric at a compression station as the roll is being fabricated. Use of the roll includes extending a shaft through the core, elevating the roll to a working height at the roof elevation, temporarily mounting the shaft to existing roof structural members of the building being constructed, and drawing a leading edge of the fabric from the roll and along a run of the space between next adjacent ones of the purlins and across the space between first and second ones of the rafters. |

1. In a process of installing a fall protection system at in a building roof structure, such building roof structure including at least first and second rafters, a space between the first and second rafters defining a first distance between the first and second rafters, each rafter having a length, and opposing first and second ends, the roof structure further comprising an eave, having a length, and extending between the first ends of the first and second rafters, a ridge, having a length, and extending between the second ends of the first and second rafters, and a second distance between the eave and the ridge, the eave and the ridge extending transverse to the first and second rafters, and a plurality of intermediate purlins, having lengths, and extending between the first and second rafters and spaced from each other between the eave and the ridge, a run extending from the first rafter to the second rafter between adjacent ones of the purlins, the fall protection system comprising a grid-work of support bands, and a suspension fabric overlying, and being supported by, the grid-work of support bands, a method of presenting the suspension fabric over the grid-work of support bands wherein the suspension fabric has been prepared as a rolled-up roll, the method comprising:
(a) extending a shaft through the roll; (b) lifting the roll to an elevation of the purlins and placing the shaft in direct contact with next adjacent ones of the purlins, with the roll suspended on the shaft and over the run which is between the next adjacent ones of the purlins; and (c) drawing the fabric from the roll and along the run toward the second rafter and onto the grid-work of bands, such that the fabric is unwound from the roll and supported by the grid-work of bands. |
