FIELD: plastic processing.
SUBSTANCE: invention relates to an apparatus for manufacturing packaging tubes. Technical result is achieved by a rotary indexing device for manufacturing packaging tubes, comprising: indexing turntable (3) mounted in a rotary manner about axis (9), mandrels (4) with respective supports (14) secured to said turntable (3) and disposed radially with respect to said axis (9), radial actuating means (10, 11) for moving mandrels (4) in a direction perpendicular to said axis (9), and linear guide means (13) for moving mandrels (4) in another direction perpendicular to said axis (9). Mandrels (4) with respective supports (14), radial actuating means (10, 11) and linear guide means (13) are disposed in a direction parallel to said axis (9).
EFFECT: technical result is shorter duration of stepped rotation and higher productivity.
