Abstract
A novel bag machine and method for sealing a novel bag is disclosed. The bag is formed by positioning adjacent end surfaces of the bag tightly together and forming a plurality of tab structures on the ends of the bag which are turned against at least one of the end surfaces of the bag to lie flush therewith. Adhesive is applied to the area of the end surfaces and the tab structures and reinforcing tape is positioned over the adhesive and over the adjacent end surfaces to cover the turned tabs. The novel machine comprises a conveyor and a perforator assembly for conveying the bag and perforating the plurality of tab structures in combination with a tab turner to turn the tabs against one of the ends of the bag. Adhesive and reinforcing tape then are introduced into the sequence after which a cut-off and a pressure group complete the sequential operation of the machine. The method for applying adhesive to both sides of adjacent surfaces on a bag or similar material is also disclosed. A bag may have one or both ends sealed in the novel manner disclosed.
