Abstract: The device includes dispensing units, each of which features a pair of counter-rotating rollers, between which there is inserted the end of a blister band unrolling from a reel and pushed toward a delivery opening. A blade moves vertically and cooperates with the edge of a support surface, situated downstream of the two rollers, to cut the blister band after a predetermined number of products, counted by a sensor, have passed through the delivery opening. An electric motor drives two ratchet coupling mechanisms acting in opposite directions and connected, by belts or chains, with pulleys or toothed wheels which are integral respectively with the rollers and with a pinion meshing with a rack fastened to the blade. An electronic unit controls and checks the working of the device. Optionally, a token, or coin receiver, a banknote reader or other payment mechanism may be used to allow the user to activate the dispenser after making a payment.
