Cushioning conversion machines and methods are provided for converting plural layers (56, 57, 58) of a sheet-like stock material into a dunnage product. The plural layers (56, 57, 58) of the stock material are shaped into a threedimensional strip of dunnage and the overlapped edge portions of a first layer (56) of the stock material are connected together separate from a central portion of the first layer (56). The overlapped edge portions of the first layer (56) may be generally coplanar with its adjacent unoverlapped portions. The overlapped edge portions of the first layer (56) may be connected together separate from other layers of the sheet-like stock material. Alternatively, the lateral edges of the other layers of the sheet-like stock material may be connected to each other and also the lateral edges of the first layer, but not to the respective central portions of the layers.
