Abstract
The present invention relates to devices for use in a loom for fluid insertion of the filling yarn, the loom having a reed, each of whose teeth defines a bulge with the opening of the bulge facing the fell of the cloth being woven to provide for better beat-up, all of said bulges together forming a guide channel for the passage of fluid which serves for the insertion of the filling yarn.
Claims8
A loom having a device for the inserting of filling yarns by means of a fluid and having a reed for beating-up of the filling yarns, each of the teeth of the reed having a bulge the opening of which faces the filling yarn beating-up point, said bulges together forming a guide channel for the fluid serving for the insertion of the filling yarn, in which the bulge of each reed tooth is adjoined smoothly by at least one approximately linearly extending portion of the tooth to present a ridgeless smooth surface on the reed tooth, and the reed is so guided in its backward and forward movements that the bulges of the reed teeth lie within the shed in the position of the reed in which the insertion of the filling yarn takes place, and the linearly extending portion of each reed tooth is at the beating-up point when the reed is in the filling-yarn beating-up position, said bulge moving along an arcuate path and out of the shed so that a weft thread insertion can ride smoothly out of the bulge of each reed tooth on the said ridgeless smooth surface to its beat-up position on said approximately linearly extending portion.
A loom having a device for the inserting of filling yarns by means of a fluid and having a reed for beating-up of the filling yarns, each of the teeth of the reed having a bulge the opening of which faces the filling yarn beating-up point, said bulges together forming a guide channel for the fluid serving for the insertion of the filling yarn, in which the bulge of each reed tooth is adjoined smoothly by at least one approximately linearly extending portion of the tooth, said linearly extending portion and its adjoining flank of the bulge of each reed tooth positioned at an angle to each other within the range of from about 135.degree. to about 180.degree., and the reed is so guided in its backward and forward movements that the bulges of the reed teeth lie within the shed in the position of the reed in which the insertion of the filling yarn takes place, and the linearly extending portion of each reed tooth is at the beating-up point when the reed is in the filling-yarn beating-up position.
