Opening roller housing for an opening roller of an open-end spinning device and open-end spinning device with an opening roller housing

Abstract

An opening roller housing (1) for an opening roller (2) of an open-end spinning machine (3) has a feed opening (4) for feeding a fiber material (5) into the opening roller housing (1), a delivery opening (6) for drawing opened individual fibers (7) out of the opening roller housing (1), a trash removal opening (8) for extracting trash (9) out of the fiber material (5), and an inner circumferential wall (10), which surrounds the opening roller (2) during operation and has a fiber-guiding area (11), which extends from the feed opening (4), over the trash removal opening (8), and up to the delivery opening (6). The opening roller housing (1) includes a hollow cylindrical ring (12). The hollow cylindrical ring (12) is designed as a self-supporting component, which is directly fastenable on a carrier part (13) of the open-end spinning machine (3) and includes the inner circumferential wall (10) having the fiber-guiding area (11) as well as the feed opening (4), the delivery opening (6), and the trash removal opening (8). An open-end spinning machine (3) includes an opening roller housing (1) of this type.

1 . An opening roller housing ( 1 ) for an opening roller ( 2 ) of an open-end spinning machine ( 3 ), having a feed opening ( 4 ) for feeding a fiber material ( 5 ) into the opening roller housing ( 1 ), having a delivery opening ( 6 ) for drawing opened individual fibers ( 7 ) out of the opening roller housing ( 1 ), having a trash removal opening ( 8 ) for extracting trash ( 9 ) out of the fiber material ( 5 ), and having an inner circumferential wall ( 10 ), which surrounds the opening roller ( 2 ) during operation and has a fiber-guiding area ( 11 ), which extends from the feed opening ( 4 ), over the trash removal opening ( 8 ), and up to the delivery opening ( 6 ), wherein the opening roller housing ( 1 ) includes a hollow cylindrical ring ( 12 ),
