发明名称 Cushioning conversion machine and method for converting stock material into a dunnage product having a casing and a stuffing within the casing
摘要 A cushioning conversion machine and method for converting multiple layer of sheet-like stock material into a cushioning product, characterized by a first shaping device which shapes a first layer of the stock material into a casing with the lateral edge portions being brought into overlapping relationship one inside the other, a second shaping device which shapes at least one second layer of the stock material into a stuffing for the for the casing, a connecting assembly downstream of the first shaping device for connecting the overlapped lateral edge portions of the first layer separate from the stuffing, and an inner feed assembly downstream of the second shaping device for feeding the second layer into the interior of the casing. The machine further comprises an outer feed assembly for engaging and feeding a central portion of the first layer, the outer and connecting assemblies being cooperative to pull the first layer through the first shaping device. The inner feed assembly is mounted to the downstream ends of cantilevered supports extending through the first shaping device from an upstream end thereof.
