Patent number: 7361132Abstract: A novel cushioning conversion machine and method for converting sheet stock material into a novel cushioning product and for producing discrete sections or pads of desired length, without the need for a cutting assembly, thereby enabling the construction of a less expensive, smaller and less complex machine. The machine and method are characterized by a weakening device for perforating a sheet stock material of one or more plies along tear lines so that as a strip of cushioning is formed from the stock material, discrete sections or pads of desired length may be detachable along the tear lines. The stock material includes material which is biodegradable, recyclable and composed of a renewable resource, such as kraft paper.Type: GrantFiled: July 31, 2007Date of Patent: April 22, 2008Assignee: Ranpak Corp.Inventors: Richard O. Ratzel, Joseph J. Harding, Michael J. Lencoski, James A. Simmons, Donald J. Barnhouse

Patent number: 6540652Abstract: A cushioning conversion machine (20) for converting sheet-like stock material (22) into a three-dimensional cushioning product (P) including a device (400; 400′; 500; 600; 600′; 700) which controls the width of the strip and which may be selectively adjusted to change the width of the strip. By selectively setting the device (400, 400′, 500; 600; 600′; 700), a cushioning product of a desired width may be produced. For more sophisticated packaging needs, the stock material may be converted into a first portion of a certain width, the device adjusted, and then the stock material may be converted into a second portion of a different width whereby the cushioning product will have continuous portions of different widths.Type: GrantFiled: November 11, 1998Date of Patent: April 1, 2003Assignee: Ranpak Corp.Inventors: Richard O.
