A machine for wrapping cigarette packs (P), or the like, each into a wrapping material sheet (F), which including a stepwise-operatable spoke wheel (1) formed with a plurality of outwardly open radial pockets (4) which are for receiving packs (P) with the relative wrapping material sheet (F) from a feeding station (A), each pocket (4) being provided at the trailing end of its mouth--relative to the direction of rotation of the spoke wheel (1), with the radial teeth (214) for retaining in position the trailing flap (L1) of the wrapping material sheet flaps (L1, L2) which are folded on the respective pack by a folder device (5, 6). The folded flaps (L1, L2) are welded together by welding device (7, 8) which are imparted with a radially directed reciprocating motion between the one and the successive step of the spoke wheel (1), so that any interference is avoided with the retaining teeth (214). The welding device (7, 8) are operated by driving device which consist of main driving device (10, 11) and an auxiliary driving device (18) that is timely set in action only when the operation of the main driving device is discontinued, whereby the function and the integrity of the machine is guaranteed.
