MODULE FOR ORYGHAMY AND METHOD FOR MANUFACTURING THE SAME Russian patent published in 2004 - IPC

FIELD: games, in particular, construction for development of mental abilities. SUBSTANCE: module has flat geometric figure defined by three parallelograms. Larger parallelogram, which is middle part of module, is joined with its smaller sides along embossed line to larger sides of two equally sized smaller parallelograms. Smaller parallelograms put together and joined with their free large sides define parallelogram congruent with largest parallelogram. Basic material for manufacture of module is thermoplastic film. Method involves releasing roll of basic thermoplastic material; stamping- cutting out blanks-tape lengths and simultaneously forming fold lines by embossment process, said fold lines defining regular geometric figures over the entire surface of blank; folding blanks along fold lines for obtaining of envelope and simultaneously joining folded free sides in mid portion of blank; cutting doubled blank and fusing by heating knife at an angle of 45 deg to longitudinal axis along cutting lines into equal strips for defining larger parallelogram and two equally sized smaller parallelograms congruent with said larger parallelogram, with detachment line extending in mid portion of module. EFFECT: increased wear-resistance and service life and increased module manufacturing efficiency. 3 cl, 10 dwg
