Abstract
An inductive projectile sensor on a gripper shuttle weaving machine or loom comprises a flat induction coil surrounding at least one of the guide teeth which are mounted on the lathe beam of the weaving machine to form a guide duct for the projectile when passing through the weaving shed. Means for magnetizing the guide tooth or teeth, such as a permanently magnetized small plate or lamella, are provided beneath the induction coil to form a magnetic core or bridge between two neighboring guide teeth, one of which is surrounded by the induction coil.
Claims6
