Abstract
An apparatus for providing a roof structure having a plurality of purlins spaced apart from one another in a parallel arrangement is disclosed. The apparatus includes a carriage which is movable in a downstream direction along the length of the purlins. The carriage pays out a support sheet for support of insulation material as the carriage travels along the length of the purlins so that the support sheet depends from the top portion of adjacent purlins. The apparatus further includes at least one roller mounted on the carriage mounted to roll along the top portion of at least one purlin and thus support and guide the carriage along the downstream direction. The roller includes a frustum portion to hinder movement of the carriage in a direction lateral to the downstream direction and thus help to maintain the carriage in alignment with the purlins.
