Boxes with separate ends
A box made with separate ends has several advantages:
- it saves material if the box has deep sides,
- it does not require corner notching,
- all cutting-out can be done with a guillotine,
- all folding can be done with a plain full-length clampbar;
and some drawbacks:
- more folds must be formed,
- more corners must be joined, and
- more metal edges and fasteners show on the finished box.
Making this kind of box is straight forward and the full -length clampbar can
be used for all folds.
1. Prepare the blanks as shown below.
2. First form the four folds in the main workpiece.
3. Next, form the 4 flanges on each end piece. For each of these folds, insert
the narrow flange of the end piece under the clampbar.
4. Join the box together.
Flanged boxes with plain corners
Plain cornered boxes with outside flanges are easy to make if the length and
width are greater than the clampbar width of 98 mm. Forming boxes with
outside flanges is related to making TOP-HAT SECTIONS (described in a
later section - see Contents).
4. Prepare the blank.
5. Using the full-length clampbar, form folds 1, 2, 3 & 4.
6. Insert the flange under the clampbar to form fold 5, and then fold 6.
7. Using appropriate short clampbars, complete folds 7 & 8.
