Air-wiping device opening and closing in one level plane
View Patent ↗An air-wiping device for removing particulates, including water, adhering to an elongated member by compressed air is provided. In particular, this invention relates to an air-wiping device that loads said elongated member by opening with a sliding motion in one plane, instead of swinging open in two planes that is commonly to the conventional air-wiping devices embodied in a clamshell configuration, which not only substantially shortens the loading time but also greatly reduces the floor space needed to accommodate said device.
1. An air-wiping device sliding to open and close in one plane to load and unload an elongated member, wherein the air-wiping device dislodges undesirable adhering particular matter from said elongated member by compressed air;
wherein the air-wiping device consists of two bodies and at least two rails, one of the bodies is stationary and the other one slides on the at least two rails, each of the bodies is inlayed with one-half piece of a cylindrical wiping passage with at least one orifice for directing the compressed air tangentially and opposite to the direction of the traversing elongated member;
wherein said rails are cylindrical and rotary, bearing against the traversing elongated member, relieving a major portion of the frictional abrasion, which otherwise exerts on the wiping passage.
2. The device of claim 1 , wherein the air-wiping device comprises a rectangular housing and consists of two metallic bodies.
3. The device of claim 2 , wherein the two metallic bodies are precisely machined, lapped, and hermetically sealed under a tension of a spring and an inward pressure of the environmental atmosphere when the device is closed under wiping, yet it will open readily to let pass knots carried by the elongated member.
