Abstract (en)

[origin: EP3260585A1] A cleaning device (100) for a drafting roller (14a, 14b, 15a, 15b, 17a, 17b) includes a scraper (150; 150A; 150B) extending along a width direction of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b) and contacting an outer circumferential surface of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b). The scraper (150; 150A; 150B) is provided with, at an end portion on an upstream side in a rotational direction of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b), a scraper edge portion (152) contacting the outer circumferential surface of the drafting roller. An angle (±) being formed by a tangent-line upstream portion (L) that is on a tangent line of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b) passing a contact point (T) with the scraper edge portion (152) and extends from the contact point (T) toward the upstream side of the rotational direction of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b), and by an upstream-side outer surface (152a) that is in an outer surface of the scraper edge portion (152) and is a surface facing the upstream side in the rotational direction of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b), when viewed along an axial direction of the drafting roller (14a, 14b, 15a, 15b, 17a, 17b), is an obtuse angle.
