Abstract
Abstract A method of producing resilient cushioning dunnage comprising taking at least one web of sheetlike material, such as paper, of predetermined width, rolling the lateral edges of the web generally inwardly, generally loosely crumpling the web with the rolled edges radially inwardly into a padlike configuration and then connecting together the confronting rolled lateral edge portions to maintain the dunnage article in its formed configuration.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
In a method of producing low density cushioning dunnage in padlike form from sheetlike material, comprising taking at least one web of sheetlike material of predetermined width, rolling the lateral edges of the web inwardly by pushing on the web laterally with a generally transversely extending means, to cause said inward rolling of the lateral edges of the web while pulling the web lengthwise thereof, crumpling the rolled edges of the web radially inwardly into a padlike configuration of relatively low density per unit volume so that the rolled edges of the sheetlike material are disposed in generally confronting abutting condition, and then connecting the rolled and crumpled edge portions together by coining of the edge portions along the juncture thereof to form a unitary padlike dunnage product.
Claim 2
Dependent Claim
128 words
In a method of producing low density cushioning dunnage in padlike form from sheetlike material, comprising taking at least one web of sheetlike material of predetermined width, rolling the lateral edges of the web inwardly by pushing on the web laterally with a generally transversely extending means, to cause said inward rolling of the lateral edges of the web while pulling the web lengthwise thereof, crumpling the rolled edges of the web radially inwardly into a padlike configuration of relatively low density per unit volume so that the rolled edges of the sheetlike material are disposed in generally confronting abutting condition, and then connecting the rolled and crumpled edge portions together by coining of the edge portions along the juncture thereof to form a unitary padlike dunnage product.
Claim 3
Dependent Claim
35 words
A method in accordance with claim 1 including pushing the formed dunnage product forwardly after said connecting Operation and applying further radial crumpling to further compress the padlike configuration into an article of greater density.
Claim 4
Dependent Claim
19 words
A method in accordance with claim 2 including continually shearing the formed padlike article transversely thereof into selected lengths.
Claim 5
Dependent Claim
97 words
A method in accordance with claim 1 including the step of providing a plurality of webs of said sheetlike material, orienting the latter into generally engaged surface-to-surface superimposed relation during said lateral pushing and lengthwise pulling of the webs, and into generally tensioned engagement with one another, prior to said radial crumpling of the sheetlike material into said padlike configuration, and wherein the step of rolling the lateral edges of the webs inwardly comprises utilizing a pusher of arcuate configuration extending generally transverse of the webs and engaging the confronting webs along the generally central portion thereof.
