Abstract: A knock-down starting platform for a roof seaming machine includes spaced side frame rails joined at one end with a platform on which a roof seaming machine may be supported and joined at their other end with a movable gate or bridge. Pins are also included to prevent disconnection of the frame rails once those rails are connected. The bridge carries a member which is adapted to be secured relative to a roof panel to support the rails and platform on a roof with the platform supported beyond the edge of the roof and the rails disposed in straddling relationship to the seam between adjacent panels. The side frame rails, the pins, latching device and bridge comprise a plurality of releasably connected together parts separable from one another to enable the starting platform to be disassembled for storage, shipment and handling in the form of a kit.

Abstract: Paper adhered to a surface with a starch-based adhesive is removed by mixing together (1) an enzyme composition containing a carbohydrase or a carbohydrase and a pratease, (2) a liquid composition containing (a) an activator for the enzyme composition, (b) a wetting agent and (c) a solvent for reducing the rate of evaporation of water from the paper, and (3) warm water, applying the resultant aqueous composition to the paper and physically removing the wet paper after the enzyme has degraded the adhesive. Prior to mixing, the enzyme composition is in a sealed moisture-proof package and the liquid composition is in another package.

Abstract: A two component article of manufacture useful for removing paper adhered to a surface with a starch-based adhesive comprising a sealed moisture-proof first package containing an enzyme composition comprising either a carbohydrase or a carbohydrase and a protease and a second package containing a liquid comprising (a) an activator for the enzyme composition, (b) a wetting agent and (c) a solvent for reducing the rate of evaporation of water from paper. Paper is removed from the surface by mixing the contents of the two packages with hot water, applying the aqueous composition to the paper and removing the paper after the enzyme composition has degraded the adhesive properties of the adhesive.
