The fibre-contacting surface 3 As a matter of convenience, the clothing-is in is composed of circumferentially-extending ribs the form of a wire of a cross-section similar to 6 alternating with circiunferentially-extending 0 that shown in Fig. 1, and includes a substangrooves 5. tially rectangular base H having a fiat inner edge Normally, in a carding roll the outer or pesurface l2 adapted to bear against the outer ripheral edge 6 of each rib 4 is discontinuous, peripheral surface I3 of the foundation cylini. e., each rib is provided with a multiplicity of der 2. In that form of the invention shown in teeth arranged with the tips I of the teeth equi- Fig. 1, for example, the wire includes a blade portion I 4 having one side face continuous with a side face l5 of the base H, and which is disposed substantially at right angles to the flat edge 12 of the wire. The blade I4 is of relatively narrower width than the base II, with that end of the blade disposed adjacent the base ll inset with respect to the second longitudinal surface I6 of the base ll providing a longitudinal recess ll along the full length of the wire. As shown in Fig. 1, the blade tapers downwardly towards its outer edge 6, which outer edge preferably is disposed at right angles portion M of the wire, as clearly shown in Figs. 1 and 2.
If alternating plain and toothed-edge ribs are desired, the convolutions are formed with two wires or multiples of two in side by side relation to each other, for groups corresponding to Figs. 5 and 6, three wires or multiples of three with two of one kind and one of another in the proper relationship to each other are wound in successive convolutions on the face of the roll.

I claim:
A roll having a fibre-contacting surface composed of alternately arranged circumferentially extending ribs and grooves formed by a series of wires of corresponding cross-sectional contours and each including a base of predetermined width seated on the roll and an upstanding blade of relatively narrower width projecting from said base, with the blade of one or more of the wires of the series provided with fibre engaging points formed in the outer edge thereof and the blade of each remaining wire oi the series having a substantially smooth outer edge devoid of said teeth, said series of wires being disposed on said roll in interwound spiral convolutions providing said surface with intermingled plain and toothed-edged ribs of equal widths separated by grooves of equal relatively greater widths throughout said surface.
