Compression device for fibrous band on spinning machine, defines constant curvature by clamping arrangements with given depth of penetration and tangential transition

摘要

The convex curvature (21) defined by the clamping arrangements has a radius of 15-30 mm. Depth of penetration (e) is 2-5 mm. The curvature transitions into a tangential plane (22), at the second clamping location (16). Curvature over the entire length (L) of the suction slot (12) has a virtually-constant radius (R).
