20180236742, Aug 23, 2018

Filed:

Jun 24, 2016

Appl. No.:

15/751494

Inventors:

- Concord Township OH, US
Peter J. Urban - Mentor-on-the-lake OH, US

International Classification:

B31D 5/00
B31D 1/00

Abstract:

A dunnage conversion machine includes a frame, a supply support coupled to the frame for supporting a supply of expandable sheet stock material, and a pair of opposed expansion members rotatably coupled to the frame for rotation about respective axes. The expandable sheet stock material is gripped between the expansion members while it is drawn between the expansion members. Tension provided between a downstream pulling force downstream of the expansion members and the gripping force of the expansion members causes expansion of the expandable sheet stock material. Portions of the expansion members are periodically recessed to provide more uniform expansion of the expandable sheet stock material while reducing or altogether preventing jamming of expanding sheet stock material between the expansion members or tearing of the expanding sheet stock material adjacent the expansion members.

Abstract:

An apparatus () for converting a slit-sheet stock material () into an expanded dunnage product () includes a housing (), a pair of rollers () within the housing extending widthwise across a path of the sheet material, and a plurality of guide strips () extending from an upstream side of the pair of rollers to a downstream side of the pair of rollers at a plurality of locations spaced across the width of the path. The guide strips guide the sheet material between and around the rollers. Exemplary rollers have a plurality of grooves spaced across the width of the path, and the guide strips are received in respective grooves. The guide strips may be connected by a crossbar to form a guide member.
