Automatic feeding machines are commonly used for filling blister packs with items of product such as pharmaceutical dosage forms. These machines are usually designed for the handling of a specific shape and sized product item. Handling of different shaped items requires expensive re-tooling of all the product item contact components. The invention allows a single feeding machine to be quickly configured for use to handling a wide variety of item sizes/shapes. A machine (21) has a tray (36) defining a series of tapered channels (40) and a container (22) slideably mounted above the tray. A wall of the container and the channels together define apertures into each channel through which items of product pass out of the container. Sliding movement of the container across the planar tray surface (38), along and over the channels, allows the size of the apertures to be adjusted depending upon the size of the item of product to be handled, using the same components.
