TURN-IN

The portion of a covering material that is folded back over the head, fore-edge and tail edges of a board and adhered on the reverse of the covered board surface. The edges of the turn-in are adhered under or on top of the doublure, depending on the material used for covering the board’s inner surface. If there are no boards, the edges may be folded back and adhered directly to the reverse of the covering material.
