The coating stays; the carrier returns
Read the diagram
Separate paths at the head. Fresh carrier tape leaves the supply reel, passes around the transfer head against the paper, then returns to the take-up reel. The white coating transfers to the paper; the used carrier continues back into the dispenser.

Three layers arrive at the head
Tombow describes an adhesive layer, a white correction coating and a base tape. The coating contains white pigment and resin; its surface is made to accept new writing. The base tape supports that thin coating on its journey through the dispenser.
At the head, pressure brings the adhesive into contact with the paper. As the dispenser moves, the carrier bends around the head and returns into the case. The transferred coating continues along the page instead of following that bend.

Why there are two reels
One reel gives up unused tape; the other collects the carrier after transfer. In Tombow's gear-driven example, movement of the supply reel drives the take-up reel. A slipping connection accommodates their changing diameters.
That detail matters because the full reel shrinks while the used reel grows. A rigid ratio between their rotations would not keep taking up the same length of tape throughout the roll.

A covered mark is still there
Correction tape adds a new writing surface over the old one. An eraser instead removes or displaces marking material. The white strip's edge is the boundary of a covering layer, not a cleaned patch of paper.

The thing to remember
The strip you see is only the transferred coating. The carrier that delivered it is collected inside the dispenser.
What this example leaves out
This is a dry transfer tape with a supply reel and take-up reel. Drive arrangements vary; it does not describe correction fluid or guarantee adhesion on every coated paper.
