The standard covering machine is equipped with a glue-pan, heating apparatus, gluing roller, glue scraper, a table, and a cut-off device. The gluing roller revolves in the glue pot, in such a manner as to apply the glue to one side of the paper as the paper passes over the surface of the roller. The glue pan may be heated by steam, gas or electricity. The scraping device regulates the amount of glue applied to the paper. When the machine is in action the operator simply wraps the strip of paper around the four sides of the box, allowing a “lap-over” of the paper, at one corner of the box, of about one inch. Some operators are careless, and they often allow “lap-overs” of several inches of paper, which of course results in considerable wastage of paper during the course of a day. The carefully-trained operator will try to save as much paper as possible. Another important point which the efficient operator will consider is in having the “lap-over” occur at one corner of the box, and not in the center of one side of the box. When the “lap-over” is made at one corner of the box, the work looks neat and finished, but when the seam is made on one side of the box, the work presents a poor appearance.

It is also very important that the work of “turning-in” should be done as neatly as possible. The “turner-in” works on a table near the covering machine. As the operator of the covering machine finishes wrapping a box, it is passed to the second operator who turns in the corners and edges of the paper. A wad of cheese-cloth, or a soft, clean cloth of any kind, is useful in the work of turning-in, the corners and edges of the paper being rubbed down firmly and smoothly. Some operators of covering machines also use a cloth in smoothing the paper as it is applied to the sides of the box. Others use merely the palm of the hand. Attached to the machine is a receptacle for holding tallow which many workers make use of for keeping their hands free from glue. On the new model covering machines the cut-off device is adjustable, up and down, by means of screws, and it can be moved to and from the box-spindle in any desired position, without it being necessary for the operator to leave his or her seat. The cut-off device may be operated by hand by means of a lever.
