posed ends in one bridge-piece. ing method permits but a small degree of transposingof the dents or rows of slips.

Consequently such reeds afford but little di minishing of friction, since the threads are still subjected to considerable compression between the dents.

In the reed forming the subject of the present invention each row of dents is united in a separate bridge-piece and the transposing of the rows of dents is effected by providing between such rows of dents spaces of a' size greater than half the width of the dents and in which spaces the threads will always lie free on one side of each dent. This arrangement is of importance in reeds for weaving bands of cloth having a variable width, for which purpose, as known, trapeze shaped reeds having an up-and-down movement; in the lay are employed. In these reeds, however, such bands or ribbons can be produced onlyin inferior qualities, because the dents at the narrow side of the reeds stand soclose together that on account of the consequent friction but few threads can be passed through.

In the annexed drawings, Figure 1 is a face view of the new reed. Fig. 2 is a horizontal sectional view at line x Fig. l. Fig. 3 is a bottom'view. Fig. 4 shows a vertical section of a reed with-two rows of slips or dents.

Like characters refer to like parts in all the figures.

The dents g g' are secured at the wide end In these reeds the*- dents are fastened or secured at their trans` Such fastenof the reed side by side in a plane, while at the 'narrow end d every alternate dent is transposed so as f to provide at such narrow end two 'rows'-v of dents, each row being engaged or united bya separate bridge-piece a a. The strip ,separating the dent-rows, provides be*- tween the latter the spaces t', which is of great importance in the trapeZe-shaped reeds, since the dents lmust be placed or distributed at the narrowvendvupon a smaller reed width.
