Abstract (en)
[origin: WO2022043363A1] The invention relates to a device and a method for treating fibers. The device has a multipart housing in which at least one first treatment tool (1, 3) and a second treatment tool (2, 4) are arranged. The treatment tools (1, 2, 3, 4) have a rotationally symmetrical shape and are arranged coaxially to each other and can be rotated relative to each other about a common axis (5). Each of the two treatment tools (1, 2, 3, 4) delimit a treatment gap (11, 12), through which the fibrous material passes in a radial direction. Two housing parts (7, 8), each of which supports at least one treatment tool (1, 2, 3, 4), are coupled together via a joint (9) which can rotate about a joint axis (13). A contact between two treatment tools (1, 2, 3, 4) is reliably detected via at least one sensor (6) arranged on the housing, preferably a sensor (6) arranged on the exterior of the housing, in order to detect vibrations of the device.
