Abstract

The invention relates to a carding machine with an infeed side (1a) for fiber batts which are fed to a pre-carding cylinder (4) and are loosened up to individual fibers and are oriented, wherein a first layer of web is transferred by means of an upper doffer (7) to a transfer roller (9) and thereafter onto a needle cylinder (11), wherein a second layer of web is transferred by means of a lower doffer (8) to a transfer roller (10) and thereafter onto the needle cylinder (11), wherein at least one layer of web is removed from the outfeed side (1b) of the carding machine by means of at least one doffer (14) for further processing. The invention is characterized in that the transfer rollers (9, 10) have the same diameter. The lower doffer (8) has a diameter which is about more than 50% of the upper doffer (7), wherein both doffers (7, 8) are designed to run at the same circumferential speed. Furthermore, the invention comprises a wire bottom for use in a carding machine.
