A non-lethal projectile consisting of a solid capsule filled with a flowable payload. The solid capsule comprises a weakened area that ruptures upon impact with a target. The solid capsule also comprises an internal hydrodynamic structure. At the moment of impact, the internal hydrodynamic structure forces the radial movement of the flowable payload, from the center to the periphery, against the weakened area of the solid capsule, facilitating the rupture and reducing the pressure of projectile's point over target's surface.

According to the present invention, a roll member is formed by winding a heat-sensitive adhesive sheet in one direction, and the heat-sensitive adhesive sheet can be smoothly deflected and easily cut to a predetermined length. A heat-sensitive adhesive sheet, while being unwound from a roll member stored in a roll member storage unit, is inserted into a printing device and is heated by a thermal head to perform printing on a printing enabled layer of the sheet. After the printing has been accomplished, the heat-sensitive adhesive sheet is conveyed forward to a guide portion until the leading edge of the sheet abuts upon a guide roof member. While contacting the guide roof member, the leading edge of the heat-sensitive adhesive sheet is slid down and guided along the guide roof member to the nip portion of a pair of insertion rollers and is held at the nip. Once the insertion rollers 13 have been halted, or have begun rotating slowly, the heat-sensitive adhesive sheet 1 is conveyed further and is deflected downward and assumes a concave shape. Then, the heat-sensitive adhesive sheet 1 is cut to a predetermined length by a cutting device, and the heat-sensitive adhesive layer of the cut portion is heated and thermally activated by a thermal activation device 5.
