Abstract: A circular comb arrangement in which a segment-shaped member has individual needle strips located parallel to each other and connected by pressure strips fastened to the segment-shaped member under pressure. The latter has a cutout holding all needle strips and pressure strips. The pressure strips are in the form of a flexible lamination having a free end fastened inside the cutout of the segment-shaped member. A pressure member is connected to the lamination, and one pressure surface of the pressure member is in contact with the subsequent needle strip as supporting surface. Behind the last needle strip, there is located a clamping strip which is detachably connected to the segment-shaped member. The clamping strip presses all needle strips and pressure members against one another and against a support surface ahead of the first needle strip.

Abstract: A pin roll includes a roll body having wedge grooves therein disposed parallel to the axis of the roll body. Pinstrips are disposed in the wedge grooves, and clamping wedges are disposed in the wedge grooves to hold the pinstrips therein. At least two parallel pegs in the roll body are disposed generally transversely of the wedge grooves. The clamping wedges have means defining oblique slots extending from the bottom thereof with the pegs being disposed in the oblique grooves. Operable means operable in a longitudinal direction and engageable with the wedge means are operable to effect securing and releasing of the pinstrips.
