INNOVATIONS:  TONGUE-IN-SLOT BOARD ATTACHMENTS

A tongue formed on the book-block (possibly with a manila card strengthener along it) is left with a tapering cut, and the board is made with three laminars, the centre one being cut away to create a slot the same shape as the tongue.

The board can be completely finished away from (for example) a large, heavy book-block, doublures or paste-downs already attached, and then slotted on to the spine piece. A tight or grooved attachment can be chosen.
