Abstract
A machine and method for the continuous folding of sheet material into difference three-dimensional patterns is featured. The innovative machine and method folds sheet material by force converging the sheet to a final stage that imparts a final fold or pattern. Unique programming allows for the change of convergence sequencing and change of materials.
Claims9
A machine for folding sheet material, comprising:
- a plurality of sets of dies, wherein each set of dies is defined by a first die and a second die, respectively;
- and
- at least one tessellation being disposed on each die of each set of dies for making a single longitudinal fold in the sheet material, wherein each immediately successive die of said set of first and second dies has two more tessellations than that of each die of a previous set of dies;
- a penultimate set of dies, wherein each die of said penultimate set of dies has a number of tessellations, said number of tessellations being two more than that of each die of a previous set of dies;
- a last set of dies, wherein each die of said last set of dies has a number of tessellations, said number of tessellations being the same as the number of tessellations as that of each die of said penultimate set;
- said last set of dies further comprising a fold pattern negatively machined on a surface of each of said dies of said last set of dies.

A method for folding sheet material with tessellated patterns, comprising:
- (a) providing a plurality of sets of dies, wherein each set of dies is defined by a first die and a second die, respectively;
- (b) providing at least one tessellation disposed on each die of each set of dies for making a single longitudinal fold in the sheet material, wherein each immediately successive die of said set of first and second dies, except for the last set of first and second dies, has two more tessellations than that of each die of a previous set of dies;
- (c) moving said sheet material through said plurality of dies;
- (d) folding said sheet material with each tessellation on each die of said sets of dies forming one corresponding fold, said plurality of dies thereby forming a plurality of folds in said material;
- and
- (e) forming a pattern on said plurality of folds by running said material through a die having a fold pattern negatively machined on a surface thereof.
