Definitions
- This invention relates to tubular core assemblies for rolls of paper or other
- Tubular core assemblies which have a hollow cylindrical core member of
- tubular core assemblies which comprise a hollow cylindrical core member of
- each annular end member is provided with at least one radially-projecting
- the present invention is based on the discovery that the problem mentioned
- each plastic annular end member has at least two
- annular surface at said end which is continuous and of constant radius around the
- the annular end member may have a pair of radially-projecting lugs which

- Fig. 5 is an exploded view of one end portion of a tubular core assembly in
- Fig. 6 is a perspective view of the tubular core assembly of Fig. 5 in an
- Figs. 1 and 2 show one end portion of a tubular
- core assembly for a paper roll which comprises a hollow cylindrical core member
- the core member 12 has multiple spirally-wound wraps (i.e. laminated
- plies of paperboard material, and the synthetic plastic material may be of suitable
- polymeric material such as injection moulding grade 25% glass filled nylon type 6.
- each end member 12 has an outer annular surface
- Each end member 14 has a pair of diametrically opposite solid lugs 18,
- the lugs 18, 20 are the same size as the
- Each end member 14 also has an end surface 26 adjacent the respective end
- Each end member 14 has an internal diameter in the range of about 3 to
- the core member has a length in the range of from about 1.5 to about 6 inches.
- thickness to core member thickness is in the range of from about 0.75:1 to about
- the lugs 18, 20 each have a height above the outer annular surface of the end
- the notches 22,24 are of course similarly sized.
- member 14 has an internal diameter of 3 inches, an external diameter of 3.75 inches
- the core member 12 has an outer diameter of 4.4 inches
- Each lug 18, 20 has a height above the outer annular surface of
- the end member 14 of 0.325 inches, a circumferential width of 0.75 inches, and an
- the notches 22, 24 are of course of substantially the
- Each end member 14 has no notches and thus has an inner surface 32
- each lug 18, 20 is solid.
- Figs. 3 and 4 show a further embodiment which is generally similar to the
- each end member 14 has three solid
- Fi s. 5 and 6 show a further embodiment which is generally similar to the
