Claims

[Scope of utility model registration request]

A guide path is formed by a row of guide holes 16, in which guide elements 14 each having a guide hole 16 and a weft reading gap 17 connected to the guide hole 16 are arranged side by side with a predetermined gap in the weft insertion direction. In the weft insertion device of an air-injection type loom, which inserts the weft by blowing the weft with auxiliary air inside the weft, the inner hole 16 of the guide 14 is connected to the narrowed part 18 which is connected to the weft escape gap 17.
and an expanded portion 19 continuous to the opposite side of the weft escape gap 17 of the narrowed portion 18, and air is ejected from the periphery of the expanded portion 19 toward a point on the axis passing through its center. A plurality of nozzle ports 22a to 22d and the narrowing portion 1
Weft insertion of an air injection type loom, characterized in that nozzle ports 23.41 are arranged at predetermined intervals in the weft insertion direction for ejecting air in a direction in which air passes through the weft opening 8 and reaches the expanded portion 19. · Device.
