The present invention provides that tea bags, especially round tea bags, are packaged in sachets by producing the sachets from a web of heat sealable material which is fed downwards and as it is, it is formed into tubular configuration, with longitudinal seam. Simultaneously, batches of round tea bags are produced and are delivered in batches to the location where the web is being formed into tubular configuration, and then are dropped into the formed web. The web is sealed transversely in synchronism with the feed of the web and the delivery of the batches so that sachets are produced each containing a pre-determined number of tea bags. Also provided is a weigher which weighs each batch of tea bags and causes the dosing of the tea in the tea bag making machine to be adjusted automatically to ensure that each sachet package will contain the correct weight of tea. |
