In the strip feeding mechanism of the invention, the main drive shaft drives meshing bevel gears on secondary shafts respectively, which extend in opposite directions with one secondary shaft being journalled by a main bearing cartridge unit. The said cartridge unit is characterized by a concentric surface and by an eccentric surface which is adjacent to the annular flanges of the unit. This novel feature of the cartridge unit enables the secondary shaft journalled thereby to be secured in the housing wall so as to eliminate all clearances in the bevel gearing and also to eliminate all clearances in the conjugate cam arrangements which are driven by this secondary shaft.
