Loom reed - has two rows of dents in relation to each other to increase density of warp pile fabrics

In the construction of the reed of a loom, there is one row of dents with a further row of fixed dents in the direction of reed movement, but spaced from the first row. Each dent of the second row is mounted to a dent of the first row, or displaced opposite it by a gap which is less than half the spacing of the first row along the length of the row. The design allows a denser adjustment to be made, partic. in the mfr. of a fabric with pile warps.
