Procedure for cleaning the retractor springs at a specialised imaging facility for weaving machines and specialised imaging equipment

摘要

To keep the springs clean at a loom harness, to form the shed, a compressed air flow is directed at the return springs to prevent a build-up of dust and fiber debris on them. The draw springs are directly or indirectly at a compressed air channel at the lowering frame, connected to a compressed air supply. The compressed air stream is continuous at a constant pressure level and/or a pressure control compensates for air flow leakages. An Independent claim is included for a harness spring cleaning assembly where the harness springs (9) are directly or indirectly in the air flow path of compressed air from a compressed air channel (12) at the lowering frame (11), linked to a compressed air supply. The air flows at the return springs prevent a build-up of dust or fiber debris on them Preferred Features: The compressed air channel (12) at the lowering frame (11) is defined by the upper seal and spring system (13) and the base (10) of the lowering frame (11). The base (14) of the compressed air channel can be raised and lowered, to alter the pressure of the compressed air flow by changing the cross section of the channel (12). The draw springs (9) are tightly against the flow, directly or indirectly at the base (10) of the lowering frame (11), as part of the compressed air channel (12), or there is an intermediate tube to hold the springs directly or indirectly at the base (10) of the lowering frame (11).
