A method and apparatus for manufacturing tagged two-ply infusion packages. The string (14) forming the tags is supplied to a rotating drum (12) which has a plurality of pins (17) protruding from its periphery. The drum (12) is rotatably mounted so as to cooperate with a web (1) used to form at least one layer of the two-ply infusion package. As the drum (12) rotates the string (14) is guided around the pins (17). The web (1) is introduced to the drum (12) by a roller (29) and urged against it by a curved guide (30) to transfer the string from the periphery of the drum to the surface of the web (1). The guide (30) is heated so as to melt the thermoplastics coating on the web (1), whereby the string is attached lightly to the web by the combination of heat and pressure from the guide (30). The web (1) with the string (14) lightly attached thereto is then sealed to a second web on which an infusion material has been deposited by heat sealing rollers (8) to form a travelling two-ply web having infusion containing pockets (11). The individual packages are then cut from the travelling two-ply web by, for example, co-rotating cutting rollers defining the shape of the packages.

Method and apparatus for making tagged infusion packages

A method and apparatus for manufacturing infusion packages such as tea or coffee bags of predetermined shape, comprises means for dosing discrete piles (7) of infusion on a first moving web (4), means (8) for sealing a second web (5) over the first to form a consolidated web with discrete infusion containing pockets (3), a co-rotating roller cutting device having cutting means and recess means to cut packages of predetermined shape e.g. circular from the web, a suction device (15) for collecting waste web and maintaining downstream web tension to transport the cut packages to a removal device (50, 51) operable to stamp the packages downwardly into stacking chambers (49).

Manufacturing infusion packages

Infusion package

A tacker which ejects magazines from a staple on operation of a handle by means of a spring biased striker protruding from the ejections slot. The tacker must first be pressed against the surface so that the protruding portion of the striker is pressed inwardly so that a pawl formed on the operating handle can then engage the striker. It is only then that the tacker can be operated.
