Abstract
The plastic projectile with an associated projectile opener has a projectile clip having arcuate parts. The projectile opener exerts forces both transversely and lengthwise of the picking direction on the arcuate parts of the clip for simultaneous opening and positioning relative to these two directions. A through aperture in the plastic casing is not touched by the projectile opener. The problem of wear in connection with conventional positioning on the plastic casing therefor disappears. A projectile made of abrasion-resistant impact-resistant plastic facilitates oil-free operation and ensures very high cloth quality.
