Abstract

An elastic cleaning lip (14, 15) for cleaning a rotating roller (4, 5, 6, 7, 8, 9, 10) of a drafting unit (1) of a textile machine has a scraper edge (21) on one of its longitudinal sides and a fastening element on its other longitudinal side for attachment to a support element (18, 19). The cleaning lip (14, 15) has a Y-shaped cross-section with a stem (20) and two substantially parallel legs (22), wherein the scraper edge (21) is arranged at the open end of the stem (20) and the two legs (22) form the fastening element for a positive-locking attachment of the cleaning lip (14, 15) to the support element (18, 19). The support element (18, 19) has receptacles (25) at its ends, and a fastening strip (24) with side surfaces (12) and end surfaces (13) is arranged between the receptacles (25). The side surfaces (12) and at least one of the end surfaces (13) are provided for the positive locking attachment of the plaster lip (14, 15).A cleaning device (16, 17) has such a support element (18, 19) and a cleaning lip (14, 15) arranged on it.
