NON-CONTACT WEB TRANSFER TURNING DEVICE

摘要

PURPOSE: A contacless web transferring and turning device is provided to minimize the amount of fluid supplied by decreasing the loss of fluid and reduce power loss by the low-speed rotation of a fluid supply source. CONSTITUTION: A contacless web transferring and turning device comprises a fluid supply source, a semicircular frame(20), a nozzle unit(30), and a blocking plate(40). The fluid supply source supplies compressible and incompressible fluid. The semicircular frame holds a plurality of fluid supply pipes formed in an axial direction along semicircular circumference. The nozzle units are installed on the outer circumferential surface of the semicircular frame. The nozzle unit is communicated with each fluid supply pipe. Coanda nozzles(33) are formed on the nozzle unit at narrow intervals.
