Roof insulation applicator with purlin connectors

An applicator for laying sheet material on adjacent parallel purlins of a roof structure comprising:

• a support carriage having opposed first and second ends,
• a reel support carried by said carriage for supporting a reel of sheet material over said carriage,
• carriage support means mounted to said carriage configured to engage adjacent purlins of a roof for mounting said applicator on the purlins, said carriage support means positioned between said first and said second ends of said carriage so that said carriage is tiltable intermediate its ends about said carriage support means when supported on purlins of a roof,
• a magnet mounted on said carriage at said first end of said carriage for attraction to a purlin on which the carriage is mounted to urge the second end of said carriage toward a purlin.

A process of progressively applying sheet material to adjacent purlins during construction of a roof, comprising:

• placing a carriage on adjacent purlins with a support roller affixed to the carriage mounted on the purlins,
• supporting a reel of sheet material on the carriage,
• moving the carriage along the lengths of the purlins,
• in response to the carriage moving along the lengths of the purlins, paying out sheet material from the reel of the sheet material about a carriage support means and onto the purlins,
• applying most of the weight of the carriage and reel of sheet material on one side of the carriage support means so as to tend to tilt the carriage in a first direction about the carriage support means toward engagement with a purlin,
• urging said one side of said carriage with a magnet toward the purlin, and
• tilting the carriage in a second direction about the carriage support means to disengage the magnet from the purlin.

A process of applying sheet material to adjacent purlins during the construction of a roof, comprising:

• placing a carriage having a framework on adjacent purlins,
• supporting a reel of sheet material on the carriage,
• moving the carriage along the purlins,
• in response to the carriage moving along the purlins, paying out sheet material from the reel of sheet material onto the purlins,
• tilting the carriage in a first direction to rest the framework on the sheet material paid out onto the purlins,
• holding the framework on the sheet material with a magnet attracted to the purlin, and
• tilting the carriage in a second direction opposite to the first direction to lift the magnet away from the purlin.

An applicator for progressively laying sheet material on spaced apart parallel purlins during construction of a roof of an industrial building wherein the sheet material is progressively applied to the purlins and roof panels are individually applied behind the sheet material, comprising:

• a support carriage for mounting on adjacent purlins, said support carriage having a front and a rear,
• a support roller mounted on said support carriage for supporting said carriage on adjacent purlins of a roof so that said carriage is tiltable about said support roller,
• a reel support mounted on said carriage for supporting a reel of sheet material on said carriage,
• said carriage and said reel support configured so that the center of gravity of said carriage, said reel support and a reel of sheet material supported on said reel support is positioned between said rear of said carriage and said support roller and tend to tilt the rear of the carriage toward the purlins,
• a pole receptacle mounted on said carriage for receiving an end of a pole, and a lifting receptacle mounted on said carriage configured to limit the upward tilting movement of a pole with respect to said carriage, and
• a pole for inserting in said pole receptacle and said lifting receptacle,
• whereby the upward tilting of a pole in the pole receptacle and in said lifting receptacle tilts the carriage about the support roller.

An applicator for progressively laying sheet material on spaced apart parallel purlins during construction of a roof of an industrial building wherein the sheet material is progressively applied to the purlins and roof panels are applied behind the sheet material, comprising:

• a support carriage for mounting on adjacent purlins, said support carriage having opposed first and second ends,
• a support roller mounted on said support carriage for supporting said carriage on adjacent purlins of a roof so that said carriage is tiltable about said support roller,
• a reel support mounted on said carriage for supporting a reel of sheet material on said carriage,
• said carriage and said reel support configured so that the center of gravity of said carriage, said reel support and a reel of sheet material supported on said reel support is positioned between said first end of said carriage and said support roller and tends to tilt said first end of the carriage toward the purlins for applying the weight of said carriage to the purlins,
• a pole engageable with said carriage for tilting said carriage about said support roller and lifting said first end of said carriage away from the purlins.

• a purlin connector mounted to said first end of said carriage, and
• a pole engageable with said carriage for tilting said carriage,
• whereby the tilting of the pole tilts the one end of the carriage about the support roller and moves the magnets with respect to the purlins.
