PURPOSE OF HOLES

Before cutting the slits in the necks, some operators punch small holes, with a bodkin or an awl, in the sides of the necks, at a point where the length of the slit is to be determined. The hole serves two purposes: First, it acts as a guiding mark when the operator cuts the slit; second, it has an influence on the lap-over, allowing it to be moved freely as the lid is placed over it.

Round, shouldered magnesia boxes are covered with glazed or enameled paper, white or colored. Trimming paper is seldom applied. When tubes, or rings of white paper have been used in the construction of these boxes, the covering paper for the side of the box and side of the lid may be cut to widths that will permit four white edges of the box to show. These white edges make the box and lid appear as though they had been trimmed with white paper. The reader is to understand, however, that in the case of a round box with projecting edges, it would be necessary to apply trimming paper, before pasting on the regular covering paper, as the trimming paper serves to hold the round piece of box-board to the edge of the ring.

In the case where the tops and bottoms of plain, round boxes are to be covered with glazed or enameled paper, there are two methods of covering: One method is in having one side of the box-board (which is to be used for the tops and bottoms of the boxes) covered with glazed or enameled paper before the box-board is cut into round pieces. The other method is in having round pieces of the paper, of desired size and color, cut out with a die, and the round pieces of paper are then pasted to the tops and bottoms of the boxes.

Labels for round magnesia boxes are usually pasted to the sides of the boxes, and for this reason the tops and bottoms of these boxes are frequently covered with glazed or enameled paper, the same color as that applied to the sides of the boxes.

As mentioned in a previous paragraph, some plain, round boxes, not having projecting edges, are trimmed on all four edges with “Round-Work Glazed Paper” before regular glazed or enameled paper is applied to the sides, but as a general rule, only round boxes with projecting edges are treated in this manner.
