FIELD: machine building.
SUBSTANCE: invention relates to machines for manufacturing paper tubes by spiral wound strips of cardboard. Machine for manufacturing cardboard tubes comprises a mandrel (M) on which the cardboard tube is formed by spirally winding the cardboard strip (S) on said mandrel (M), a winding member configured to interact with a mandrel (M) and a strip (S) of cardboard to effect said spiral winding, an input section, intended for filling a strip (S) of cardboard, pulling device configured to exert a pulling action on the strip (S) of the cardboard, introduced along said predetermined retraction direction, said pulling means functioning during the filling step, cutting means, intended for configuration of strip (S) of cardboard with a configuration suitable for winding it onto the mandrel (M), and guide means configured to guide the strip (S) of cardboard to the mandrel (M) at the end of said charging step, wherein said guiding means are arranged and functioning between the pulling means and the mandrel (M).
EFFECT: technical result is improved safety.
