  • Vanishing target and arrowhead projectile therefor
    Patent number: 4462598
    Abstract: A target system includes a target sheet (10) comprising a polyester film (20) adhesively secured to a paper or polyethylene backing sheet (15). The polyester film (20) defines an exposed target surface (F) and includes a plurality of circular target strike zone portions (T) defined by spaced apart slits (S) perforating the polyester film (20). The circular target zone portions (T) are not adhesively secured to the backing sheet (15) and are integrally connected to the polyester film (20) with connecting portions (30) each located between adjacent slits (5). A rounded impact head (42) of a projectile (40) striking a target portion breaks the connecting portions (30), causing the target portion (T) to detach from the polyester film (20) and be pulled through the backing sheet (15) to achieve a vanishing effect. In another embodiment, separate zone portions (T) can be secured to the backing sheet with minute adhesive portions (25') or adhesive tape (32).
