<p>Automatic machine for packaging products of various kind into bags of heat weldable plastic material, in which the bags are obtained from a continuous band formed by two thin sheets overlapped and joined to each other along their side edges, or formed by a single sheet. Machine comprising a first and a second movable roll (15, 23), which can be moved away and approached to each other, and provided with cutting means (29) and sealing means (31, 44) of the continuous band (6), and also comprising a first and a second pliers carrying support (32, 37) provided with a relative grasping pliers (34, 39) of the continuous band (6), which can be moved away and approached to each other, and detaching means (42, 43) of the bag which has been formed and filled with the desired products. During the operation, the continuous band (6) is unwound from a feeding roll (9) and advanced through the movable rolls (15, 23), the pliers (34, 39), the cutting means (29) and the sealing means (31, 44'), so as to form a bag which is then welded, filled with the products and detached from the machine.</p> |
