发明名称 Perforated cushioning dunnage product, machine and method for making same
摘要 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.
