Craft device for making aerial projectiles from sheet material |
摘要 |
A craft device for use in constructing aerial projectiles and in particular, paper airplanes. The device includes a press having a lower die portion and an upper die portion pivotally connected thereto along one edge. A plurality of detents or protrusions on the lower die portion are provided in alignment with complementary holes in the upper die portion and serve to perforate a suitable sheet of material such as paper to define a plurality of fold lines on the sheet. The device includes a template alignable on the sheet so that a particular design or coloration can be applied to the sheet to add realistic characteristics to the projectile. A nose piece is frictionally secured to one edge of the sheet to maintain the folds and add a predetermined amount of weight to aid in flight control.
