The purpose of a sewing frame is twofold: When sewing a single book-block, the sewing frame holds the tapes or cords upright, assisting in neater, faster sewing. A sewing frame also makes edition sewing onto tapes possible. Edition sewing is sewing a succession of the same size book-block in a stack and separating them when sewing is complete by sliding them along the tapes and snipping off enough of the tape for each one.
Many types of ‘home made’ sewing frames available via the internet, have mechanisms to to stretch the cords and tapes to a significant degree of tension. This is not only unnecessary but detrimental, particularly when sewing onto cords. Over-stretching the cords will result in the signatures being pulled too tightly together when released from the sewing frame and rounding or backing will be rendered impossible. Tapes and cords do not need to be stretched under tension like guitar strings, they simply need to be held upright without slackness.
Our sewing frame is designed to enable sewing onto both tapes and cords and also enables edition sewing onto tapes. It is simple to use and folds flat for easy storage.
