Abstract: An apparatus for packaging resiliently compressible articles is disclosed. In one embodiment, the apparatus has at least two rotatable, spaced apart article engaging elements adapted to receive an end portion of an article for rolling the article into a compact rolled up configuration. Each article engaging element can be rotatably mounted to one of at least two arm portions, which are desirably pivotally mounted to the apparatus. At least one of the arm portions can be adapted to be movable in a lateral direction. The apparatus may also be provided with a vacuum hose fluidly connected to a vacuum source for vacuum packing an article desirably before it is rolled-up. A spring containing mattress is also disclosed, which, in one embodiment, comprises plural rows of springs and substantially C-shaped border wires extending around the periphery of the end portions of the upper and lower surfaces of the mattress.

Abstract: A foam dispensing gun of the type having a disposable nozzle for mixing and dispensing separate fluid components of a resin system. The nozzle is retained on the gun by a sliding breech which also pivotally supports a valve actuating trigger to be in an operative position when the breech is moved to retain a nozzle to the gun and disabled when the breech is moved to release the nozzle for reloading. The breech and trigger may be further arranged so that the trigger is inoperative in the absence of a nozzle on the gun.
