Title:
REED OF AIR JET LOOM
Document Type and Number:
Japanese Patent JP2006016725
Kind Code:
A
Abstract:

To provide a technical means for preventing lowering of rigidity of dents while improving weft introduction functions into a guide groove in relation to a reed of an air jet loom in which the guide groove for guiding the weft yarn is formed at the front and the upstream end of the guide groove is smoothly extended so as to receive the weft yarn and a carrying air stream thereof.

The problems are solved by forming the bottom edge 15 of a recessed part 3 of each dent in the upstream end side forming an extending part into a circular arc shape and deepening the groove depth in the central part of the vertical width of the guide groove. A part in which the front and rear width W2 of the reed between the bottom edge 15 and the rear edge 17 of the reed is reduced is sufficiently only a part of the central part of the vertical width in the guide groove by deepening the groove depth of the guide groove in the extending part. Since the shape in each part of the bottom edge 15 provides a nearly constant distance from the weft yarn flight center, an improvement in functions to introduce (catch) the weft yarn and the carrying air stream thereof into the guide groove 4 can be expected.
