Abstract
In one embodiment of the present invention, a device for supporting and storing wound material thereon may include a substantially cylindrical, hollow bobbin having a thickness defined by an inner and outer diameter for supporting and storing material wound around the exterior surface thereof, and a reinforcing apparatus located at one end of the bobbin, the apparatus having generally a cylindrical shape and a length comprising two zones, the outside surface of the first zone being in contact with a portion of an inner surface of the bobbin, and the second zone of the apparatus extending beyond the end of the bobbin.
Claims24
A device for supporting and storing wound material thereon, comprising:
- a substantially cylindrical, hollow bobbin having a thickness defined by an inner and outer diameter for supporting and storing the material wound around an exterior surface of the bobbin, and
- a reinforcing apparatus located at one end of the bobbin, said apparatus having generally a cylindrical shape and a length comprising first and second zones, an outer surface of the first zone being in contact with a portion of an inner surface of the bobbin, and the second zone of the apparatus positioned entirely beyond an end of the bobbin, the first and second zones secured to one another through a releasable connection,
- wherein the first zone has an outer diameter such that the first zone fits within the inner surface of the bobbin and wherein the second zone has an outer diameter larger than the inner diameter of the bobbin,
- whereby the reinforcing apparatus provides strength and support to the bobbin.
A product for maintaining or storing a wound stock material, comprising:
- a substantially cylindrical, hollow cardboard bobbin for winding and maintaining the wound stock material thereon;
- and
- a first reinforcing apparatus in connection with the bobbin located at an end of the bobbin and characterized by adding rigidity, strength and protection to the bobbin, the first reinforcing apparatus including a first zone, a portion of which is positioned within the bobbin, and a second separate zone, positioned on another portion of the first zone, the first and second zones secured to one another through a releasable connection,
- wherein the wound stock material is wound on the bobbin and reinforcing apparatus.
A device for supporting and storing wound material thereon, comprising:
- a substantially cylindrical, hollow bobbin having an inner and outer diameter for supporting and storing the wound material around an exterior surface of the bobbin, and
- a reinforcing apparatus located at one end of the bobbin, said apparatus having generally a cylindrical shape and a length, the reinforcing apparatus comprising a first cylindrical sleeve portion having a flanged end, at least part of which is in contact with an inner surface of the bobbin, and a second, separate cylindrical end portion, at least a part of which is positioned over the first sleeve portion, the first and second portions secured to one another through a releasable connection, wherein the second end portion has an outer diameter larger than the inner diameter of the bobbin,
- wherein at least a part of the first sleeve portion has a first outer diameter such that the part of the first portion having the first outer diameter fits within the inner diameter of the bobbin,
- whereby the reinforcing apparatus provides strength and support to the bobbin.
