BASIC THEORY OF BUCKLE FOLDING

If a sheet of paper is laid on a flat surface and driven
into a stationary object, a buckle or series of buckles
will form along the surface of the sheet.
If the sheet of paper is pushed into a narrow channel
before butting up against the stationary object, the
buckles that form within the channel will be of a much
smaller size than free-forming buckles. At the end of
the channel, however, larger buckles will again start
to form.
