Abstract

A method for producing packaging cushioning includes successively feeding sheets of a substrate at a first speed to a crumpling mechanism, crumpling the sheets at a second speed to convert the sheets into packaging cushion units, and controlling at least one of the first and second speeds to produce a desired degree of overlap between successive sheets, thereby generating a connected series of the packaging cushion units.
