Patent ID: 8319946

Claim:
A transfer device for feeding a tape-shaped work to a process stage arranged along a vertical direction in which the work is fed vertically, the transfer device being located on one side of the process stage, said transfer device comprising: a supply reel around which the work and a protective sheet for covering a surface of the work are wound, the supply reel for feeding the work to the process stage and feeding the protective sheet to a different direction from the process stage; a take-up reel located lower than the supply reel; the take-up reel winding the work being processed in the process stage and the protective sheet that have been fed from the supply reel; a work feeding mechanism for feeding the work from the supply reel to the take-up reel through the process stage; and a protective sheet feeding mechanism for feeding the protective sheet from the supply reel to the take-up reel; the protective sheet feeding mechanism having a first roller located lower than the supply reel and a second roller located higher than the take-up reel, for guiding the protective sheet from the supply reel to the take-up reel, and a first air dancer for adjusting a tension of the protective sheet to be fed to the take-up reel; the first air dancer being located between the first roller and the second roller; the work feeding mechanism having a third roller and a fourth roller for guiding the work to the process stage from the take-up reel, and a second air dancer which adjusts a tension of the work between the third roller and the fourth roller; the work feeding mechanism having a fifth roller and a sixth roller for guiding the work fed from the process stage to the take-up reel, and a third air dancer which adjusts a tension of the work between the fifth roller and the sixth roller; the fifth roller, the sixth roller and the third air dancer being located lower than the take-up reel; the third air dancer being located below the second air dancer; wherein the work and the protective sheet are wound around the take-up reel in balance by adjusting the tension of the work and the tension of the protective sheet with the third air dancer and the first air dancer, respectively.
