A method of manufacturing books, which contain a number of coupons or cheques, documents etc., arranged in the form of folded-up strips (10, 11,12) where each strip is attached at one end in a cover (7) and can be unfolded to its full length, starting from a symmetrically folded cover (7) and printed sheets comprising coupons arranged in rows and columns, where along one short side of the sheets a flap (6) is located. Each sheet 1 has break perforations (5) and, respectively, tear perforations (4) between each column and, respectively, row of coupons. A cover intended for several books is provided with break perforations (13) in a spaced relationship corresponding to the width of a desired book. Thereafter in a first step at least as many sheets (1) as desired strips in a book are laid upon each other in a stack and are folded along the tear perforations (4) into wave shape. In a second step the uppermost sheet (1) in the stack is drawn off and the folding is completed, whereby the sheet, seen in cross-section, is folded up in zigzag pattern, with the flap (6) projecting outward. Thereafter the folded-up sheet according to a third step is inserted into said cover, whereafter the second and the third step are repeated until as many sheets (1) as desired strips in a book have been inserted into the cover (7), whereby thus a number of folded-up sheets (1) are inserted in a row of as many coherent covers (7). In a fourth step the cover (7) for each book is stapled together with the flaps (6) inserted into the cover, whereafter in a fifth step the row of coherent books are broken apart along the break perforations (13 and, respectively, 5) in the cover (7) and sheets (1). <IMAGE> |
