<p>A feeder for the gripper head of wrapping machines for small- and medium-size products, comprising: a disk (6;306), which substantially lies horizontally and rotates about a vertical axis (7); recesses (8;308) for receiving a respective product (4a;304a), which are distributed all around the disk, are spoon-shaped and have a slot (12;312) which is open towards the outside of the disk and can be crossed substantially along a plane that passes through the vertical axis; an extractor (17-18;317-318) which cooperates, in a transfer station which corresponds to one of said recesses (8;308) and to a gripper (3;303), with a corresponding complementary element (129) and with a device for dispensing a piece (5;305) of material in sheet form and is suitable to intersect and pass beyond the recess with an active stroke in the vertical plane, passing through the slot in an upward and outward direction so that the product (4a;304a) and the material in sheet form (5;305) are secured against the complementary element and so that by means of the complementary element (129) the product and the material are inserted in the gripper, whilst the extractor performs its return stroke below the disk (6;306). <IMAGE></p> |
