Abstract: An apparatus for continuously winding web material into a succession of rolled packages includes spaced side frames which define a transfer path leading from a first winding station to a second winding station. A plurality of rotatably driven winding drums extend between the side frames and support the cores and packages wound thereon during a winding operation which begins at the first winding station and continues during transfer of the cores to the second winding station. Tracks are fixed to the side frames which mount a transfer carriage movable on the tracks between the first and second winding stations. A first hold down mechanism and a first rider roll are carried by the carriage and a second hold down mechanism and second rider roll are located at the second winding station. The first hold down mechanism engages grooves in the ends of mandrels which are inserted into the cores to axially stabilize the mandrels.
