Abstract:
A cushioning conversion machine for converting sheet stock material into a relatively lower density cushioning product as the sheet stock material moves through the machine from an upstream end toward a downstream end, comprising a forming assembly including a former about which lateral regions of the stock material turn as the stock material moves through the forming assembly, the former including a top portion having a pair of generally longitudinally extending, and coplanar converging lateral and laterally spaced top edges that support the lateral regions of the stock material as the lateral regions turn inwardly around the former and which converge toward each other, and at least one two longitudinally spaced side edge-depending edges that extend obliquely from each of the top edges, and the side edges defining therebetween a space recessed in relation to the side edges wherein the sheet stock material can move to enhance crumpling, thereby facilitating Progression of the sheet stock material past the side edges while inhibiting tearing.
