Abstract
Roof insulation applicator ( ) for applying sheet material to the roof of an industrial building includes a carriage ( ) for mounting on adjacent purlins ( and ) of a partially completed roof. Support roller ( ) is applied by the carriage to the upper surfaces of the purlins ( and ) and the carriage is tiltable about the support roller ( ). The center of gravity of the carriage ( ) is applied rearwardly of the support roller ( ). Purlin engager ( ) is mounted to the front of the carriage and engages under the upper laterally extending flange ( ) of the purlin ( ) and limits the downward pivoting of the rear end of the carriage applying a lever arm effect by the weight of the rear portion of the structure to the support roller ( ). This firmly holds the sheet material in its stretched configuration extending from the roof panel ( ) out to the support roller ( ), reducing the tendency of the sheet material to sag in between the adjacent purlins. Magnets ( and ) are mounted to the rear of the carriage to hold the carriage against the purlins when the purlin engagers are inoperative.
