Abstract: A book of removable forms such as a cheque book, also comprises interleaved counterfoils, secured at the fold line of the book cover, on which a copy is produced when the cheque is written. Separators are provided between cheques and respective counterfoils (except for the uppermost cheque which is ready to write). After writing and removing a cheque, its separator is automatically partially withdrawn by the action of folding back its counterfoil for storage in a pocket on the cover. The separator is then torn out and discarded, thereby preparing the next cheque to be written and copies made onto its counterfoil. The arrangement allows facsimiles of the cheques to be produced on the counterfoils, which are stored in a non-removable manner.
