Abstract
A cushion producing machine includes a frame, a forming assembly mounted to the frame for creating a cushioning product from sheet-like stock material, the forming assembly including a triangular plate coacting with a pair of curved surfaces to inwardly roll the lateral edges of the stock material to form a continuous strip having lateral pillow-like portions and a thin central band, and a coining assembly for coining the central band of the continuous strip.
Claims24
A cushion producing machine, comprising:
- a frame;
- a forming assembly mounted to the frame for creating a cushioning product from sheet-like stock material, the forming assembly including a triangular plate coacting with a pair of curved surfaces to roll inwardly lateral edges of the stock material to form a continuous strip having lateral pillow-like portions and a thin central stand;
- and
- a gear assembly for engaging at least the central band of the continuous strip.
An assembly for converting a cushion producing machine suitable for producing dunnage product from sheet-like stock material of a certain width to a machine suitable for producing dunnage from a smaller width sheet-like stock material, comprising:
- a forming assembly insert sized to fit within a larger forming assembly, the insert including a triangular plate coating with a pair of curved surfaces to roll inwardly lateral edges of the stock material to form a continuous strip having lateral pillow-like portions and a thin central band.
A cushioning conversion machine for converting a sheet-like stock material into a cushioning product, said machine comprising:
- a frame,
- a forming assembly mounted to the frame which forms the sheet-like stock material into a three-dimensional strip having lateral pillow-like portions separated by a central band, and
- a feed assembly which feeds the sheet-like stock material through the forming assembly;
- wherein the forming assembly includes a triangular plate and a member including a pair of curved surfaces which together cause lateral edges of the stock material to roll inwardly to form the three-dimensional strip;
- and
- wherein the pair of curved surfaces each include a bight portion and the triangular plate includes a pair of side edges which extend into the bight portions of the curved surfaces.
