Leno selvedge forming device, has bearing ring comprising circumferential distributed openings for compressed air supply, where circumferential distributed openings are arranged in region of bearing collar

摘要

The device has an electric motor including a rotor (1) and a stator (10), where the rotor includes guide openings (3, 4) for leno threads (30, 40). The rotor is retained through a bearing ring (20) using an air suspension, and includes a rotary bearing channel (7). The bearing ring includes a rotary bearing collar (28) corresponding to shape of the bearing channel, where the bearing ring comprises circumferential distributed openings (28b) for a compressed air supply. The distributed openings are arranged in a region of the bearing collar.
