Abstract
The picking mechanism has a torsion rod whose zero position is adjustable by an adjusting lever and an adjusting drive. A rigid wedge-shaped intermediate member movable by the adjusting drive is disposed between a sliding surface of the adjusting lever and a stationary sliding surface. Movement of the intermediate member produces a pivoting movement of the adjusting lever to alter the zero position. The intermediate member transfers a force exerted by the adjusting lever on to the stationary sliding surface.
Claims14
A picking mechanism for a projectile loom comprising
- a torsion rod having a longitudinal axis;
- an adjusting lever secured to said rod for rotating said rod about said axis relative to a zero position of said rod;
- and
- an adjusting mechanism for pivoting said lever about said axis to vary said zero position of said rod, said mechanism including a rigid intermediate member disposed between said adjusting lever and a stationary surface and a drive for moving said member relative to said lever to effect a corresponding pivotal movement of said adjusting lever while transferring a force from said lever onto said stationary surface.
A method of operating a picking mechanism in a projectile loom, said method comprising the steps of
- turning a torsion rod connected with a picking lever about a longitudinal axis thereof from a zero position to affect picking of a projectile;
- and
- adjusting said zero position of the rod stepwise directly after each picking of a projectile wherein the zero position to increase stressing of the rod is adjusted immediately before a planned interruption of operation.
