Abstract
The invention provides a table top folding apparatus that is easily reconfigured to provide a single fold folding apparatus or a multi-fold folding apparatus. The apparatus includes a frame, having first and second roller pairs and a first fold table and a second fold table positioned to receive material from the respective roller pairs. The apparatus also includes a fold selector assembly rotatably attached to the frame, the assembly including a diverter and a stop fence. The fold selector assembly is adjustable by a single actuation arm to rotate between a single fold position and a double fold position. The invention further provides a tabletop folding apparatus having independently adjustable fold selector and material diverter assemblies.
Claims19
A tabletop material folding apparatus comprising:
- a frame;
- first and second roller pairs operably attached to the frame;
- a first fold table positioned to receive material passed through the first roller pair;
- second fold table positioned to receive material passed through the second roller pair;
- and
- a fold selector assembly rotatably attached to the frame, the fold selector assembly including a diverter and a stop fence, wherein the fold selector assembly is rotatable between a single fold position and a double fold position, wherein when the fold selector assembly is rotated to the single fold position the diverter is positioned to divert material passing through the first roller pair into the second roller pair and the stop fence is positioned at a first fold position of the second material fold table, and when the fold selector assembly is rotated to a double fold position the diverter is positioned to allow material into the first fold table and the stop fence is positioned in a second fold position of the second fold table,
- wherein the fold selector assembly includes a selector shaft including a cam, the diverter including a plurality of diverter fingers and a diverter arm, the stop fence attached to the selector shaft, wherein rotation of the selector shaft positions the stop fence and simultaneously interfaces the cam with the diverter arm to position the plurality of diverter fingers between the first fold position and the second fold position.
A tabletop material folding apparatus comprising:
- a frame;
- first and second roller pairs operably attached to the frame;
- first material fold table positioned to receive material passed through the first roller pair;
- a second material fold table positioned to receive material passed through the second roller pair;
- a diverter shaft rotatably attached to the frame, wherein the diverter shaft is rotatable between a single fold position and a double fold position, wherein when the diverter shaft is rotated to the single fold position the diverter shaft is positioned to divert material passing through the first roller pair into the second roller pair and when the diverter shaft is rotated to a double fold position the diverter is positioned to allow material into the first fold table;
- and
- a selector shaft operably engageable with the diverter shaft, wherein the selector shaft includes a selector cam, the diverter shaft including a diverter and a diverter arm, a stop fence attached to the selector shaft, wherein rotation of the selector shaft positions the stop fence and simultaneously interfaces the cam with the diverter arm to position the diverter between the single fold position and the double fold position.
A tabletop material folding apparatus comprising:
- a frame;
- first and second roller pairs operably attached to the frame;
- a first material fold table positioned to receive material passed through the first roller pair;
- a second material fold table positioned to receive material passed through the second roller pair;
- a diverter shaft rotatably attached to the frame, wherein the diverter shaft is rotatable between a single fold position and a double fold position, wherein when the diverter shaft is rotated to the single fold position the diverter shaft is positioned to divert material passing through the first roller pair into the second roller pair and when the diverter shaft is rotated to a double fold position the diverter is positioned to allow material into the first fold table;
- a selector shaft;
- and
- a stop fence attached to the selector shaft, the diverter shaft including a diverter and a diverter arm, wherein rotation of the selector shaft positions the stop fence between a first fold position and second fold position.
A tabletop material folding apparatus comprising:
- a frame;
- first and second roller pairs operably attached to the frame;
- a first fold table positioned to receive material passed through the first roller pair;
- a second fold table positioned to receive material passed through the second roller pair;
- means for diverting the material from entering the first fold table;
- means for stopping the advancement of the material within the second fold table;
- means for simultaneously adjusting the diverting means and
- the stopping means.
