Abstract
A roll core is adapted for fitting into an open end of a roll core for supporting said roll core while said roll core is capable of rotating with respect to said handle. The handle includes a hollow holder body having a plurality of side-by-side side wall arcuate segments and a plurality of stiffening ribs formed longitudinally around the holder body, wherein the stiffening ribs are positioned spacedly apart to separate the plurality of arcuate segments into groups of resilient rotor supports adapted for compressive constraint within said roll core for enabling the roll core to be smoothly rotated with respect to the holder body. The handle further includes a flange radially and outwardly extended from a proximal end of the holder body integrally.
Claims23
A handle for fitting into an open end of a roll core respectively for supporting said roll core while said roll core is capable of rotating with respect to said handle, wherein said handle comprises:
- a hollow holder body having a proximal end and an end wall, wherein said holder body is longitudinally divided into a proximal portion extended from said proximal end to a middle portion of said holder body and a distal portion extended from said proximal portion to said end wall, wherein said proximal portion has an outer diameter arranged for fitting into said open end of said roll core for rotatably supporting said roll core and said distal portion has an outer diameter smaller than that of said proximal portion for preventing direct contact with an inner surface of said roll core, wherein said holder body further has a plurality of side-by-side side wall arcuate segments longitudinally extended around said proximal portion for enabling said roll core to be smoothly rotated with respect to said holder body;
- and
- a flange radially and outwardly extended from said proximal end of said holder body integrally.
A handle for fitting into an open end of a roll core for supporting said roll core while said roll core is capable of rotating with respect to said handle, wherein said handle comprises:
- a hollow holder body having a plurality of side-by-side side wall arcuate segments and a plurality of stiffening ribs formed longitudinally around said holder body, wherein said stiffening ribs are positioned spacedly apart to separate said plurality of arcuate segments into groups of resilient rotor supports adapted for compressive constraint within said roll core and derives from such compressive constraint for enabling said roll core to be smoothly rotated with respect to said holder body;
- and
- a flange radially and outwardly extended from a proximal end of said holder body integrally.
A roll core supporting apparatus comprising a pair of cylindrical handles, each of said handles having a generally circular side wall, said side wall comprising a plurality of side-by-side arcuate segments adapted for outward spring bias deflection for gripping a roll core interiorly at one end thereof, wherein said side wall provides an axially directed seam enabled for parting said side wall.
