Abstract: Apparatus for introducing fresh bobbins containing supplies of convoluted web material into and for evacuating expired bobbins from web consuming machines has a reservoir for a horizontal row of coaxial fresh bobbins and a conveyor system for delivery of selected fresh bobbins directly to one of several stub shafts on a turntable which is indexible about a horizontal axis parallel to the common axis of the fresh bobbins in the reservoir. The conveying system includes an elevator which is movable into the reservoir from below to engage and lift a selected fresh bobbin and to thereupon transport it directly onto the selected stub shaft. An expired bobbin, normally in the form of a hollow core, is engaged by a gripper which moves it off the respective stub shaft and into a magazine which is adjacent and parallel to the reservoir.
