Abstract
In a coating film transfer tool, a tape is unwound from a supply reel, fed over a transfer head, and wound onto a take-up reel driven from the supply reel by a drive mechanism having slippage. Instead of setting the average slipping torque at a high value, or minimizing its variations, to prevent it from falling below the winding threshold, the initial slipping ratio is set at a value of at least 34%. This avoids slackening of the tape without the need for close manufacturing tolerances or lubricants, and without causing a condition in which excessive force is required to wind the tape onto a take-up reel in the later stages of the tool's useful life.
