Abstract
A dunnage conversion machine (10) and method for providing strips of dunnage that better fill a void in a container are characterized by means (24) for separately guiding at least two sheets of stock material (14 and 16) to respective laterally-disposed regions of an inlet (20) to a conversion assembly (40) such that one sheet does not wrap around another sheet, and means (12) for converting the sheets into strips of dunnage that can readily separate and follow separate paths.
Claims20
A dunnage conversion method comprising the steps of (A) separately guiding at least two sheets of stock material to respective laterally-disposed regions of an inlet to a conversion assembly such that one sheet does not wrap around another sheet;
- and (B) converting the sheets into strips of dunnage that can readily separate and follow separate paths.
A dunnage conversion machine, comprising:
- a conversion assembly having an inlet and an outlet that advances, inwardly gathers and crumples sheet stock material as the stock material passes through the conversion assembly;
- and laterally-spaced guides upstream of the conversion assembly that define separate paths to laterally-disposed regions of the inlet such that one sheet does not wrap around another sheet, whereby the crumpled strip exiting the outlet can readily separate and follow separate paths.
A dunnage conversion machine, comprising means for converting sheet stock material into a dunnage product as the stock material travels from an inlet to an outlet of the converting means;
- and means for guiding multiple sheets of stock material to respective laterally-disposed regions of the inlet of the converting means such that one sheet does not wrap around another sheet.
