Abstract: A machine (M) for producing blister packs (10) includes unrolling means (3,7,21) for unrolling a band of heat-formable material from a bobbin (2) and for feeding the band (1) along a predetermined path (P) extending through subsequent stations (5,6,30,8,9,13), in which the band (1) is processed. The above-mentioned stations include a heating station (5), where the band (1) of heat-formable material is heated, a forming station (6), where a plurality of blisters (20) are formed on the band (1), a filling station (8), where the blisters (20) are filled with products, a sealing station (9), where the blister band (1a) is closed with a sealing band (11), and a cutting station (13), where the closed blister band (1ac) is cut into blister packs (10). A further heating station (30) is provided for heating the blister band (1a) along the path (P) upstream of the filling station (8), so as to heat the band (1a) to cause a thermal stabilization treatment of the blister band (1a).

Abstract: The device is used in conjunction with a step-driven conveyor featuring an upper surface where seats for receiving blister packs are placed with transverse portions of each blister packs protruding symmetrically from the relative seat. At a station where these seats stop one after the other, there is a vertical magazine, open below, centered with respect to the station and containing a stack of blister packs supported by spring-operated retaining means. Below the magazine, there are two arms one on each side of the upper surface, equipped above with suction cups, and vertically movable in a synchronous manner. Actuation of the arms, combined with action of the suction cups, enables a blister pack to be transferred from a seat present at the station to the magazine, and vice versa.
