ABSTRACT:
Apparatus for producing and separating a string of interconnected packing cushions comprises a packing cushion production machine which produces a string of interconnected packing cushions, the string of interconnected packing cushions exiting an output end of the machine at a first velocity, and a separation device associated with the output end of the machine, the separation device adapted to selectively engage the string of interconnected packing cushions and to drive the string at a second velocity, greater than the first velocity, and in doing so to cause the string of interconnected packing cushions to separate. The method comprises producing a string of interconnected packing cushions, or supplying a pre-produced string of interconnected packing cushions, the string of interconnected packing cushions traveling at a first velocity, and selectively engaging the string of interconnected packing cushions at a second velocity, greater than the first velocity, and in doing so causing the string of interconnected packing cushions to separate.
