Abstract: A device (1) for packaging finely divided, moistened tobacco material in individual portion packages, comprising a means (2) for feeding the material into pockets (4) formed in a rotary portioning wheel (3) for portioning the material into portions. The device further comprises at least one compression means (10, 11, 12) for compressing these portions, a unit (23, 27) for advancing a packaging material (17) in synchrony with the compressed portions, at least one means (14, 15, 16) for discharging the portions from the pockets and advancing them the packaging material, and a unit (28, 29, 30, 31, 33) for forming individual portion packages from the discharged portions and the packaging material. At the intended point of discharge of the portions to the packaging material, said material has the form of a tape (17), the compression means (10, 11, 12) being arranged to compress the portions in a direction which differs from the discharging and the feeding directions.

Abstract: It has not been possible hitherto to equip outer wrappings (10) for (tobacco) bagpacks of the twistbag type (11) with a tear-open thread or strip (15). The present wrapping (10) is provided with a tear-open strip (15) extending transversely relative to the longitudinal extension of the twisting (11). A longitudinal edge strip (17) with a longitudinal welding seam (18) is folded round against a wrapping wall (19,20) and fixed at the ends by transverse welding seams (21,22). A process and apparatus for producing such a twistbag.
