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 3½inches to approximately 4 inches in width and approximately 1 to 1¼inches 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.

A converter mechanism for taking paper in stock roll form and converting it into a narrow width and small size pad-like cushioning product for use for instance, in packaging and comprising lateral juxtaposed portions which have been coined transversely thereof generally centrally and lengthwise of the cushioning product, to maintain said portions in generally connected relation, and forming an elongated pad-like product, said converter mechanism comprising a frame, means on said frame for causing inward rolling of the lateral edges of the sheet-like stock material into generally rolled form, said means including a longitudinally extending converging funnel-like chute member and a coacting former member, extending lengthwise and interiorly of said chute member, the latter including a widened entrance end portion and relatively narrower exit end portion, means for rotatably mounting a multi-ply stock roll of the sheet-like material, for supplying the latter to the first mentioned means, and coining means on said frame disposed downstream from said chute member and adapted to receive from said exit end portion the generally abutting rolled edge sheet-like stock material between the bite of said coining means and operable to connect the generally abutting rolled edge stock material into pad-like cushioning dunnage product form, said coining means being operable to pull the sheet-like stock material from the stock roll through said chute member and past said former member, and to coin the inwardly rolled edge stock material for the major portion of the transverse dimension of the pad-like product, thereby forming the product with a lengthwise extending generally central coined portion and lateral non-coined edge portions extending lengthwise of the product, said former member comprising an elongated generally rectangular shaped, in plan, bar having its forward end positioned generally adjacent said exit end portion of said chute member and its rearward end extending rearwardly of said entrance and end portion of said chute member, said former member extending lengthwise of said chute member along the vertical longitudinal center plane of said chute member.
