Pushing member for apparatus for paying out a roll of insulation material

摘要

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. As the carriage moves in the downstream direction, a support sheet for support of insulation material is payed out so that the support sheet depends from adjacent purlins. The apparatus further includes a plate which is attached to the carriage. The plate supports a roll of insulation material which is unsupported axially. The insulation material is connected at the upstream end of the roof structure and is payed out on top of the support sheet as the carriage moves along the length of the purlins. The apparatus also includes a pushing member which pushes on the exterior surface of the roll of insulation material as the carriage moves along the length of the purlins, thereby assisting in unrolling the roll of insulation material so that the roll of insulation material moves simultaneously with the plate.
