Abstract
Abstract A method for removal of newsprint paper remaining on cores after the majority of the rolled paper on the cores has been used for printing newspapers, the method comprised of emplacing the depleted roll with core in a cradle positioned parallel to an open-end, rotatable shaft with polished surface, partially uncoiling the depleted roll, then causing the paper to be transferred from the core to the rotating shaft, removing the paper from the open end of the shaft and disposing thereof, retaining the core for future use.

A method for separating newsprint paper from the core upon which it is wound, after said core and newsprint paper have been utilized in a newspaper printing process, comprising a. Starting with i. A core upon which a depleted amount of newsprint paper is wound, ii. A cradle, iii. An open-end, rotatable shaft located in parallel proximity to said cradle, iv. A friction bar located in parallel proximity to said cradle and shaft offset from any imaginary line drawn between the center of said shaft and the center of a core placed in any location in said cradle, v. A drive motor, housing and frame to which said shaft, cradle and friction bar are attached, and vi. A switching means for energizing said motor; b. Placing said core with newsprint paper in said cradle; c. Pulling the exposed end of said newsprint paper to slide over said friction bar then to surround said shaft; d. Causing said shaft to rotate by activating said switching means and motor; e. Transferring said newsprint paper from said core to said open-end shaft; f. Causing said shaft to cease rotating by de-activating said switching means and motor; and g. Removing said newsprint paper while in rolled configuration from the open-end of said shaft.
