Abstract (en)
[origin: EP3321399A1] A spinning unit (2) includes a draft device (6) and a pneumatic spinning device (7) adapted to supply a yarn (Y), a yarn accumulating roller (54) adapted to accumulate the supplied yarn (Y), and a front cover (60) arranged on a front side than the yarn accumulating roller (54) and formed with an opening (61) for exposing the yarn accumulating roller (54) to the front side. The front cover (60) includes a main body part (62), and a first edge member (63) and a second edge member (64) that form an edge of the opening (61). The first edge member (63) and the second edge member (64) have hardness higher than hardness of the main body part, a fusion point higher than a fusion point of the main body part, and a surface roughness smaller than a surface roughness of the main body part.
