Abstract This invention is directed to apparatus for sequentially packaging items in a chain of imbricated bags mounted on two strands of tape including a stationary support table, a tape puller, a forced air bag opener, a tray for inserting articles in the bag, indexing means operated by the bags for positioning the bags for loading; a method for sequentially loading such a chain of bags, supporting the bags in the loading position, opening the bags by directing air stream over and then into the bag, loading article via tray into bags; a special power supply apparatus for driving the tape puller including air motor, drive clutch and lock clutch; and a cartridge equipped chain of imbricated bags; all as further described hereafter.
A method of sequentially loading a chain of imbricated bags comprising sequentially moving a bag into a loading position, firmly supporting the bottom of the bag in the loading position, reducing the air pressure above said bag and partially opening the bag, directing a stream of fluid into the partially open bag and increasing the pressure inside the bag and fully opening the ag, positioning the front inward portion of the bag under the bag, edge of the tray, and when the stream of fluid is directed into the partially open bag the bag is caused to ride up under the forward portions of the tray and hump up so that its upper lip is drawn up along the forward edge of the tray and caused to flip out above the forward edge of the tray, the article is loaded into the tray and shoved from the tray into the bag without moving the tray further into the bag and the bag is then removed from the tray.
