BEVERAGE PREPARATION MACHINE

A clamping mechanism for a beverage cartridge is provided, comprising: a frame; a tray suitable for receiving a beverage cartridge therein; a clamp; and an actuator. The tray is coupled to the frame to allow the tray to move between a brewing position and a loading position. The actuator is pivotably connected to the clamp and the clamp is pivotably connected to the frame to allow the clamp to be pivoted between a clamped position and an unclamped position on rotation of the actuator relative to the frame. The tray is engagable with the clamp during movement of the tray into the loading position to move the clamp from the unclamped position to a raised position.
