ABSTRACT:
Carding roller apparatus for processing staple fibers is disclosed which includes rollers combined to form operative carding units (A) to provide a desired effect which may be combined to provide a desired levelling and carding of fibers. The operative units consist of a high speed roller (1, 5, 9, and 13) having a carding point with a working roller (2, 6, 10, and 14). There is a stripper roller (3, 7, 11, and 15) in advance if each working roller as seen in the travel direction. The first roller (1, 5, 9, and 13) is contacted by a fourth roller (4, 8, 12, and 16) which acts as a carding and transfer roller with fiber circulation and additional fiber storage between the next operative carding unit. By the additional carding points with fiber circulation and by the additional fiber storage, the apparatus provides improved levelling and opening qualities as compared to conventional carding arrangements.
