Abstract:
A threading apparatus for threading the start of a printing-material web through an offset bar region of a rotary printing machine using a pulling device for pulling a threading point connected to the start of the printing-material web, the printing machine having a path for the printing material web along a longitudinal direction of the printing machine, said apparatus comprising:a guide rail arrangeable parallel to the longitudinal direction of the printing machine alongside the path in the offset bar region, said guide rail being guidably connectable to the pulling device so that the threading point is guidable through the offset bar region by said guide rail;a pair of parallel offset bars arranged in said offset bar region for laterally offsetting the printing material web; andguide means extendable perpendicular to the longitudinal path for receiving the printing-material web during the threading operation, said guide means being arranged relative to said guide rail so that the printing material is threadable around said guide means instead of said offset bars, said guide means being removable from the longitudinal path.
