ABSTRACT:
A profiled weaving reed, especially for shuttleless looms with pneumatic weft thread insertion, has profiled reed teeth which are so deformed along the path of weft thread insertion that a first deformation forms an edge slanted in the direction of weft thread insertion while a further deformation on the opposite side of the respective reed tooth is slanted in the opposite direction. The first deformations may, for example, have a bent edge. The first and further deformations of all individual reed teeth form, over the width of the reed a type of groove or throat in which the weft thread is guided. The deformations prevent or greatly reduce an air loss through the reed and improve the air flow transporting the weft thread.
