ABSTRACT A plastics core for use in a paper or plasticsheet roll, e.g. for a cash register or the likepaper rolls, is produced by cutting an indeterminatelength of an extrusion molded, unitary, tubularstructure to a predetermined length. The tube or thecore comprises two concentric, radially spaced,thin-walled cylindric members and a plurality ofpreferably radial, thin ribs maintaining thecylindric members at their radial spacing. Thecore is lighter than known cores, can easily beproduced by slicing an extrusion molded product andhas an increased dimensional stability.
