Hinging In A Single Text Page

Tear a strip of Japanese repair tissue approximately l/2” wide and as long as the height of the page. Japanese tissue tends to stretch a little lengthwise when wet so it can be trimmed a little shorter than the page.

• Lay the page to be hinged on a piece of wax paper or non-stick material.
• Lay a strip of Japanese repair tissue on a piece of waste paper and mask one half of the width of the tissue.
• Brush wheat paste on to the exposed side, remembering to brush across the waste paper toward the edge of the Japanese tissue.
• Remove the waste paper from the Japanese repair tissue and carefully lay the repair tissue on the inner margin of the page to be hinged. The pasted half of the Japanese tissue strip should be laid on the page while the half that is not pasted hangs off the page.
• Use a folder to gently smooth the feathered edge of the repair tissue into the repaired page working from the middle of the Japanese tissue strip toward the edge. Take note of any excess paste. Try to use just enough paste to adhere the tissue to the paper and not so much that it is forced out the edge of the repair.
• Cover the repair with wax paper or non-stick material and blotter paper then dry under weight. If blotter paper is used, changing it every 10 – 15 minutes will speed the drying time.

When the first half of the repair is dry, trim the top and bottom edges of the Japanese tissue if they extend past the edge of the paper.

• Fold the Japanese tissue back toward itself to form the hinge. Place wax paper and waste paper under the folded hinge, with the waste paper closest to the pasted Japanese tissue. Lay the page, wax paper and waste paper on a sheet of waste paper and carefully paste the exposed Japanese tissue. Be careful not to get paste  under the Japanese repair tissue or beneath the printed page.
• Remove the waste paper and carefully position the hinged page in the book.
• Use a folder to work the page and repair hinge into the inner hinge.
• Double check placement of the page and hinge. Make sure the hinge is smooth and all the way back into the hinge area. Check to see that the edges of the hinged page match the edges of the top and bottom of the text block.

MAKE SURE THE PAGE IS RIGHT SIDE UP!

• Place a piece of wax paper on either side of the Japanese tissue repair so the moisture will not travel into the text block.
• Put the book in a press or rods in the joints and dry under weight Keep the book under pressure until it is completely dry. If the Japanese hinge or the paper feels cool, it is not completely dry.

If the edges of the hinge have not adhered to the page, apply a small amount of paste to the edge and gently work it in place with a folder. Replace the wax paper or non-stick material, close the book and dry under weight.

Trimming The Hinged-In Page
The edges of the hinged-in page may not be even with the rest of the text block. If the paper extends beyond the edges of the text block, trim it with a sharp knife and ruler. Do not use scissors as they will not cut a straight edge.

• Place a thin piece of cardboard under the page to be trimmed to protect the text block. 
• Slip a flat metal ruler between the page to be trimmed and the page before it.
• Line up the edge of the ruler so it is even with the edge of the page before it.
• With a very sharp knife, trim the excess margin from the page beneath the ruler.
