Seamless paper reel
Abstract
A paper reel includes a lining, and an enclosure mounted on a
periphery of the lining. Thus, the plastic enclosure encompasses a
whole length of the paper lining to reinforce the strength of the
paper reel, so that when an element, such as a tape, cloth, weaving
strap, metallic foil, car insulating paper or the like, is closely
wound around the paper reel, the paper reel will not be deformed or
distorted due to compression, thereby enhancing the quality and
stability of the paper reel.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a paper reel, and more
particularly to a seamless paper reel for winding a tape, cloth,
weaving strap, metallic foil, car insulating paper or the like.
[0003] 2. Description of the Related Art
[0004] A conventional paper reel is used for winding a tape, cloth,
weaving strap, metallic foil, car insulating paper or the like, and
comprises a lining including a plurality of paper strips
overlapping each other in an oblique manner to form a tubular body,
and a paper strap wrapped around a periphery of the tubular body
formed by the paper strips. However, the conventional paper reel
has a weaker strength, so that it is easily deformed or distorted
due to compression, thereby decreasing the quality of the
conventional paper reel.
SUMMARY OF THE INVENTION
[0005] In accordance with the present invention, there is provided
a paper reel, comprising:
[0006] a lining; and
[0007] an enclosure mounted on a periphery of the lining.
[0008] The primary objective of the present invention is to provide
a seamless paper reel.
[0009] Another objective of the present invention is to provide a
paper reel, wherein the plastic enclosure encompasses a whole
length of the paper lining to reinforce the strength of the paper
reel, so that when an element, such as a tape, cloth, weaving
strap, metallic foil, car insulating paper or the like, is closely
wound around the paper reel, the paper reel will not be deformed or
distorted due to compression, thereby enhancing the quality and
stability of the paper reel.
[0010] A further objective of the present invention is to provide a
paper reel, wherein the lining is formed by a winding process, and
the plastic enclosure is made by a plastic injection molding
process, so that the paper reel is made easily, exactly and
rapidly, thereby enhancing the working efficiency and decreasing
costs of fabrication.
[0011] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] FIG. 1 is a partially cut-away perspective view of a paper
reel in accordance with the preferred embodiment of the present
invention;
[0013] FIG. 2 is a partially cut-away perspective view of a lining
of the paper reel as shown in FIG. 1;
[0014] FIG. 3 is a partially perspective view of the lining of the
paper reel as shown in FIG. 2; and
[0015] FIG. 4 is a partially enlarged perspective view of the paper
reel as shown in FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings and initially to FIGS. 1-3, a
paper reel in accordance with the preferred embodiment of the
present invention comprises a lining 10, and an enclosure 20
mounted on a periphery of the lining 10.
[0017] The lining 10 includes a plurality of paper strips 11
overlapping each other in an oblique manner, and a plurality of
grooves 12 located between the paper strips 11 in an oblique
manner. Preferably, the grooves 12 of the paper strips 11 are
arranged in a helical manner. The paper strips 11 are wound around
a helical winding track in an oblique manner so as to form a
tubular body. The paper strips 11 are juxtaposed to each other in
an oblique manner.
[0018] Referring to FIGS. 1-4, the lining 10 further includes a
paper strap 13 mounted between the paper strips 11 and the
enclosure 20. The grooves 12 of the paper strips 11 are covered by
the paper strap 13 completely. The paper strap 13 is substantially
tubular and has a length equal to that of the tubular body formed
by the paper strips 11. The paper strap 13 is radially wrapped
around a periphery of the tubular body formed by the paper strips
11. The paper strap 13 is harder than each of the paper strips
11.
[0019] The enclosure 20 is made of plastic material. The enclosure
20 is substantially tubular and is wrapped around a periphery of
the paper strap 13.
[0020] In assembly, an adhesive is bonded on a side of each of the
paper strips 11. Then, each of the paper strips 11 is wound around
a helical winding track of a winding machine in an oblique manner
with a determined pitch, so that each of the paper strips 11 is
bonded layer by layer so as to form a tubular body. In addition,
the paper strips 11 are juxtaposed to each other in an oblique
manner to form the grooves 12. Then, an adhesive is bonded on a
side of the paper strap 13 and the paper strap 13 is radially
wrapped around the periphery of the tubular body formed by the
paper strips 11 so as to form the lining 10. In such a manner, the
grooves 12 of the paper strips 11 are covered by the paper strap 13
completely. Finally, the lining 10 is mounted in a tubular die and
a plastic material is injected into the die to form the enclosure
20 which is wrapped around the periphery of the lining 10. Thus,
the lining 10 and the enclosure 20 form a seamless paper reel as
shown in FIG. 1.
[0021] Accordingly, the plastic enclosure 20 encompasses a whole
length of the paper lining 10 to reinforce the strength of the
paper reel, so that when an element, such as a tape, cloth, weaving
strap, metallic foil, car insulating paper or the like, is closely
wound around the paper reel, the paper reel will not be deformed or
distorted due to compression, thereby enhancing the quality and
stability of the paper reel. In addition, the lining 10 is formed
by a winding process, and the plastic enclosure 20 is made by a
plastic injection molding process, so that the paper reel is made
easily, exactly and rapidly, thereby enhancing the working
efficiency and decreasing costs of fabrication.
[0022] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
