In plants where this machine is in operation, the work is handled as follows: First, the sheets are cut square or oblong to the required size. Second, the corners for regular paper boxes, or the corners for extension bottom work, are cut from the paper. Third, the wrappers are fed through a gluing machine, which by means of rollers, places a thin coating of glue on one side of the paper. Fourth, the sheets, with the glue-side up, are placed on a revolving table which is really a part of the wrapping machine. Fifth, from the revolving table the operator of the wrapping machine lifts up a wrapper with one hand, and with the other hand takes an uncovered box, placing it bottom down on the glued paper, being careful to see that the bottom of the box is accurately centered between the cut out corners of the wrapper. Sixth, the box and wrapper are then placed on a form on the wrapping machine. The action of the machine thereafter is “almost human.” The box and its wrapper pass down through a series of brushes and rollers which draw the wrapper closely to the sides of the box, neatly folding the paper at the corners and ends, and turning in the edges of the wrapper on the inside of the box. At the end of a complete revolution of the machine the box emerges from the machine in a finished condition.

In some of the larger paper box manufacturing plants, where Stokes & Smith machines are being used, a great deal of time is being saved by grouping the machines, and by working the operators in teams. For example, two wrapping machines and two gluing machines are so arranged that the boxes and the lids are finished, inspected and assembled with all of the work being done in one small “department.” In not a few shops the boxes and lids are covered on machines which are located a considerable distance apart, resulting in a waste of time when the boxes and lids are assembled. The accompanying illustration will give the reader an idea of how the machines may be properly grouped so as to eliminate unnecessary handling:
