MAKING BOXES (USING SHORT CLAMPBARS)
There are numerous ways of laying-out boxes and numerous ways of folding
them up. The MAGNABEND is ideally suited to forming boxes, especially
complex ones, because of the versatility of using short clampbars to form
folds relatively unhindered by previous folds.
Plain Boxes
1. Make the first two bends using the long clampbar as for normal bending.
2. Select one or more of the shorter clampbars and position as shown. (It is
not necessary to make up the exact length as the bend will carry over gaps
of at least 20 mm between the clampbars.)
For bends up to 70 mm long, just select the largest clamp piece that will fit.
For longer lengths it may be necessary to use several clamp pieces. Just se-
lect the longest clampbar that will fit in, then the longest that will fit in the
remaining gap, and possibly a third one, thus making up the required length.
For repetitive bending the clamp pieces may be plugged together to make a
single unit with the required length. Alternatively, if the boxes have shallow
sides and you have available a slotted clampbar, then it may be quicker to
make the boxes in the same manner as shallow trays. (See next section:
TRAYS)
Lipped boxes
Lipped boxes can be made using the standard set of short clampbars provided
one of the dimensions is greater than the width of the clampbar (98 mm).
1. Using the full-length clampbar, form the length wise folds 1, 2, 3, &4.
2. Select a short clampbar (or possibly two or three plugged together) with a
length at least a lip-width shorter than the width of the box (so that it may
later be removed). Form folds 5, 6, 7 & 8. While forming the folds 6 &
7, be careful to guide the corner tabs either inside or outside the sides of
the box, as desired.
