The machine (10) is used for trimming the fore-edge of books (22) formed from a book block (24) with its spine either sewn or milled and glued, and from a flexible cover (23) the openable parts (26, 28) of which are provided with respective inwardly folded flaps (27, 29). It comprises: at least one conveyor device (19, 49) for conveying the books (22), each conveyor device (19, 49) comprising two superposed belts (18, 20; 48, 50) mounted about relative pulleys, the distance between the adjacent branches of the two belts (18, 20, 48, 50) being equal to the thickness of the books (22), these latter being fed in regular succession to one end of the conveyor device (19, 49) with their spine parallel to its direction of movement (A) and their fore-edge to be trimmed projecting from the belts (18, 20; 48, 50), a trimming blade (36) movable in a vertical plane parallel to the direction of movement (A) of the books (22); and a presser (42) and counter-presser (43) to make contact with respectively opposing parts of the book block (24) which are adjacent to the cutting plane of the trimming blade (36) The machine (10) further comprises two furrower means (34, 40), one for each of the two faces of the books (22), each (34, 40) to be inserted, starting from the fore-edge, between the relative openable part (26, 28) of the cover (23) and the book block (24) to open this openable part (26, 28) before the trimming operation is carried out on the fore-edge, to prevent the blade (36) from interfering with the cover (23).
