Abstract

A converter mechanism and method for producing a relatively narrow width and small size cushioning dunnage product of pad-like form, from sheet-like stock material. A conversion kit comprising a funnel-like chute member and a coacting elongated generally rectangular shaped (in top plan) bar former is provided for conversion of a known cushioning dunnage converter into one which can produce the relatively narrow and small size pad-like cushioning dunnage product of the invention. The bar former has its forwardmost end disposed generally adjacent the exit end of the funnel-like chute member, with its rearward end extending rearwardly of the entrance to the funnel-like chute member. The narrow width and small size dunnage product produced on the instant converter mechanism possesses a density of approximately one pound per cubic foot, and is between approximately 31/2 inches to approximately 4 inches in width and approximately 1 to 11/4 inches in thickness, and is especially useful for packaging and cushioning small parts, as well as for effectively cushioning edges of products, for instance furniture or the like, during shipment thereof.
