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.
Claims21
A method for producing packaging cushioning, comprising:
- a. successively feeding sheets of a substrate at a first speed to a crumpling mechanism;
- b. crumpling said sheets in said crumpling mechanism, said crumpling mechanism crumpling said sheets at a second speed to convert said sheets into packaging cushion units;
- and
- c. controlling at least one of said first and second speeds to produce a desired degree of overlap between successive sheets, thereby generating a connected series of said packaging cushion units, wherein said connected series of packaging cushion units has a density that is proportional to said degree of overlap between successive sheets.
A machine for producing packaging cushioning, comprising:
- a. a feed mechanism for successively feeding sheets of a substrate at a first speed;
- b. a crumpling mechanism for receiving said sheets from said feed mechanism and crumpling said sheets at a second speed to convert said sheets into packaging cushion units;
- and
- c. a controller for controlling at least one of said first and second speeds to produce a desired degree of overlap between successive sheets, thereby generating a connected series of said packaging cushion units, wherein said connected series of packaging cushion units has a density that is proportional to said degree of overlap between successive sheets.
