Abstract
A card wherein at least the pre-carding zone, located between the licker-in and the revolving flats is subdivided into a multiplicity of angular ranges with respect to the axis of the main cylinder, all of which have a unified angular extension or an integral multiple of this unified angular extension. In this zone, or in several of these zones on both sides of the main cylinder there are exchangeable fastening plates, lying opposite to each other in pairs, which can be fitted to the card shells, whereby the angular extension of the fastening plates around the axis of the main cylinder corresponds to the unified angular extension or to an integral multiple of this angular extension. Each pair of fastening plates with the component parts fitted thereto forms an exchangeable, pre-adjusted module whereby the components comprise groups or combinations of the same or different pieces of equipment of a card and each has an angular extension around the axis of the main cylinder which corresponds to the unified angular extension or to an integral multiple of this unified angular extension.
