ABSTRACT:
A machine for closing the lids of a box, especially overfilled agricultural produce boxes. The flaps of a paper box are individually closed and pressed shut to compact the contents within the box, and make ready for fastening the lid closed. The machine includes a continuously moving conveyor means on which the boxes are placed for movement through the closing and compacting portions of the machine and into and out of the lifting and fastening portion of the machine. Belt means and movable and stationary finger means are used in combination with a compacting mechanism to close the flaps and compact the box. A lifting device between and below the conveyor means lifts the boxes off of the moving conveyor into engagement with a fastening device that fastens the flaps of each box shut before it is lowered back onto the conveyor belt for movement out of the machine. The lifting device is a platform operated by a lifting mechanism which may be guided by a parallel or encircling telescoping tube. The telescoping tube has the extreme opposite ends fixed. One end is fixed to the platform while the opposite end is fixed to the machine. The telescoping tube receives the lateral force of the conveyed boxes.
