<p>Method and apparatus to provide a tea bag with a cover. The tea bags (1) slide (2) onto a length of cover material (3) where they are attached at one edge only, using heat sealing, etc. (7). The cover material is creased (5, 9) and cut (13), the rollers (10, 11) serving to forward it and the bags attached thereto. Blade (15) pushes the creaseline of a cover so that bag and cover are forced between rollers (16, 17) to fold the cover about its bag. In an alternative, blade (15) pushes each bag and cover between two spring steel plates whereby the pressing of the plates folds the cover about its bag.</p> |
