Abstract
An apparatus (10) for converting a slit-sheet stock material (16) into an expanded dunnage product (12) includes a housing (20), a pair of rollers (22, 24) within the housing extending widthwise across a path of the sheet material, and a plurality of guide strips (90) 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.
