  • Publication number: 20250242961
    Abstract: A film transfer tool has a casing, a tape-supplying assembly having a supply reel and a take-up reel linked therewith, a brake component which can move relative to the supply reel, and a transfer head. The transfer head moves between an original position and an operating position to drive the tape-supplying assembly and the brake component to move relative to the other. When the transfer head moves toward the operating position, a relative movement between the supply reel and the brake component is caused and the braking capacity gradually decreases.
