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.
Claims9
A weaving reed for weaving looms with pneumatic weft thread insertion, comprising profiled reed teeth each with a nose projection for forming a weft thread guide channel, each nose projection having a recessed portion (4') for guiding a weft thread through said guide channel, said recessed portion having a first deformation including a first bevelled edge (4") the bevel of which is slanting in the direction (S) of weft thread insertion for an improved guiding of an air flow carrying a weft thread through said guide channel and for preventing or at least reducing an air loss through gaps between neighboring reed teeth, each of said reed teeth having a further deformation (7) located on its profiled reed tooth substantially in a weft thread contact zone, said further deformation (7) slanting in a direction opposite to the weft thread insertion direction, said further deformations causing a partial, downwardly directed air stream (T) for guiding said weft thread along said nose projections.
