  • Pneumatic powered pinking shears
    Patent number: 5511313
    Abstract: An electric/pneumatic pinking shear with one touch button blade closure. The blades In these shears are shorter than previous blades because of the twisting and bending moments of long thin blades. The bending moments of the blades have been reduced so that shear tension between the blades can be kept to a minimum. The teeth on the blades are wider than other pinking shears in order to improve the quality of the finished cut. This will decrease the amount of thread unraveling after the fabric is cut.
