Abstract

In an electrically-controlled device for programmable weft cutting in gripper weaving looms, of the type comprising two blades (1, 2) to be operated at the time of insertion of the weft (T) into the carrying gripper (P), said blades (1, 2) are controlled by cam means (5 to 8) driven by an electric motor (9) programmable according both to the main motion of the loom and to the textile features of the weft yarn. Said blades (1, 2) are carried by two oscillating arms (3, 4) and said cam means comprise two cams (7, 8) arranged side by side and mounted coaxially on the shaft (9A) of the programmable motor (9), and the relative cam followers (5, 6) carried by said blade-mounting arms (3, 4). These arms (3, 4) are preferably mounted parallel to each other and side by side, oscillating about the same axis (O), the shaft (9A) of the motor (9) and of the cams (7, 8) being parallel to the oscillation axis (O) of the blade-mounting arms (3, 4).
