ABSTRACT A cushioning pad for the packaging and storage of fruits. Such pad contains a chemical composition such as cal- cium hydroxide for removing carbon dioxide and/or ethylene from the atmosphere to retard ripening and prevent damage to the fruit. The pad may also contain a hygroscopic chemical such as calcium chloride. The system and mechanism for dispensing a metered amount of the particulate chemical material onto a series of moving batts to form the pads includes a supply conveyor system for the chemical. In one embodiment a vertical holding column is used to feed the intake end of a horizontal ribbon auger conveyor. A second embodiment utilizes an inclined chute holding column which feeds a hopper mounted over a paddle wheel unloader system. The material is finally dispensed from a hopper means by a belt dispensing conveyor and by means of a metering gate system deposited onto the surface of moving batts passing therebeneath. Cam switch control means are used to coordinate the dispensing of material with the speed of travel and length of the batts and to provide positive metering and stop and start dispensing flow cycles.
