Abstract
A cushioning conversion machine and method for converting sheet-like stock material, such as paper in multi-ply form, into cut sections of relatively low density pad-like cushioning product. The machine includes conversion assemblies which convert the stock material into a strip of dunnage, a stock supply assembly which supplies the stock material to the conversion assemblies, a cutting assembly which cuts the strip into cut sections of a desired length, and a post-cutting constraining assembly which circumferentially constrains the cut section.
Claims6
A cushioning dunnage conversion machine for converting sheet-like stock material, such as paper in multi-ply form, into cut sections of relatively low density pad-like cushioning dunnage product, said machine comprising:
- a frame having an upstream end and a downstream end;
- conversion assemblies, mounted on said frame, which converts such sheet-like material into a strip of a pad-like cushioning dunnage product;
- a stock-supply assembly, mounted on said frame upstream of said conversion assemblies, which supplies such stock material to said conversion assemblies;
- a cutting assembly, mounted on said frame downstream of said conversion assemblies, which cuts such strip into a cut sections of a desired length;
- and
- a post-cutting constraining assembly, mounted on said frame downstream of said cutting assembly, which circumferentially constrains such cut sections.
A method of producing cut sections of relatively low density pad-like cushioning dunnage product, comprising the steps of:
- supplying a sheet-like stock material;
- converting the sheet-like stock material into a strip of a pad-like cushioning dunnage product;
- cutting such strip into cut sections of a desired length;
- and
- circumferentially constraining such cut sections.
