Description
CROSS REFERENCE TO RELATED PATENT APPLICATION
[0001] This patent application claims the priority benefit of a
Chinese patent application No. 200520057639.X filed on Apr. 27,
2005.
FIELD OF THE INVENTION
[0002] The present invention relates to the art of soles and
methods of manufacturing the same, and especially to a sole glued
with cloth and a method of manufacturing the same.
BACKGROUND OF THE INVENTION
[0003] Soles of shoes that people usually wear are commonly made of
synthetic rubber material. Such soles are always so stiff that the
impact between soles and the floorboard while walking at home may
easily break the expensive floorboard. And the friction between the
soles and the ground while walking on the street may also easily
abrase the soles. The prior method to solve above problems is to
glue cloth onto a front portion and a heelpiece of the sole so that
the soft cloth which contacts the floorboard and the ground could
not only avoid breaking the floorboard of a city family but also
protect the sole from abrasion by the hard ground.
[0004] At present, one method of gluing the cloth onto the sole is
to put the cloth in a mold first, then perfuse the mold with raw
material. The sole and the cloth connect together after cooling,
and the cloth attach to the bottom of the sole. But the raw
material may infiltrate into the cloth during the perfusion process
so as to affect the pliability and the aesthetics of the cloth on
the sole. Another method of gluing the cloth onto the sole is to
glue the cloth from the outside. The first is to manufacture a sole
and treat its bottom surface with solvent, and then daub glue on
the sole twice after roasting. The sole should be roasted after
each daubing process. Finally the cloth is glued onto the sole.
Because the above working procedure are mostly operated by people,
it has the following disadvantages: (1) The petroleum used as the
solvent is easy to volatilize into the air during treatment and
roasting process and it may injure people when inbreathed by
people; (2) The inconvenient and repeating operations are waste of
manpower, material resources and electric power; (3) It is
difficult to glue the cloth onto the correct place so that it may
easily result in brokenness or disuse of the cloth when it is glued
onto a incorrect place and torn to glue again, so as to increase
the production cost; (4) The daubing and gluing processes need 4
workers to complete. It is easy to pollute the sole and workers
often need to do poorly done work over again.
SUMMARY OF THE INVENTION
[0005] In order to overcome those disadvantages of the prior art, a
main object of the present invention is to provide a novel sole
glued with cloth to achieve a fast connection of the cloth and the
sole, and to ensure that the cloth is glued onto a correct place
and the cloth has a neat facies.
[0006] Another object of the present invention is to provide a
method of manufacturing a sole to solve the problem that the raw
material may easily infiltrate into the cloth during the perfusion
and molding process. And the method of the present invention can
achieve a close connection of the cloth and the bottom surface of
the sole.
[0007] In order to fulfill the above objects, the present invention
provides a sole which comprises a sole main-part and cloth defined
on the bottom surface of said sole main-part, a film being defined
between said cloth and the bottom surface of said sole
main-part.
[0008] Said film is made of polyamine ester.
[0009] Said sole main-part is made of polyamine ester.
[0010] Said cloth and said film are connected by hot pressing after
a daubing process.
[0011] Said film and said sole main-part are connected by a
perfusion and molding process.
[0012] Compared with the sole of the prior art, because of the film
additionally defined between the cloth and the sole main-part, the
connection of the cloth and the sole is very fast, the cloth is
absolutely in a correct place and the facies of the cloth is
neat.
[0013] The method of manufacturing the sole of the present
invention comprises the following processes: (1) Daubing glue on
the cloth and gluing the film onto it; (2) After leaving the cloth
still for a period of time, cutting the cloth glued with the film
to desired shapes and then putting the cloth into a mold of the
sole, the surface which is glued with the film being upward and the
other surface contacting a lower mold; (3) Perfusing the liquid raw
material which is used to manufacture the sole into the mold for
molding, the bottom surface of the sole close connecting to the
film so that the cloth connects to the sole after molding.
[0014] Said film is made of polyamine ester.
[0015] Said sole is made of polyamine ester.
[0016] In the process (1), the cloth is daubed with glue and glued
with the film by a daubing glue device and then hot-pressed to
connect with the film.
[0017] In the process (2), the cloth is leaved still after being
rolled up.
[0018] In the process (2), the period of time for leaving still the
cloth is no less than 24 hours.
[0019] Compared with the prior art, because of the film
additionally defined between the cloth and the sole main-part, the
connection of the cloth and the sole is very fast, the cloth is
absolutely in a correct place and the facies of the cloth is neat.
The following are the advantages of the method of manufacturing the
sole of the present invention: the daubing process operated by the
daubing glue device decreases the injury to people; the perfusing
process which is operated after putting the cloth in the mold could
glue the cloth onto a correct place; and the consumption of
manpower and material resources is lesser; the film glued to the
cloth could obstruct the liquid raw material from infiltrating into
the cloth and keep the cloth clean and neat.

DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring to FIGS. 2 and FIGS. 3, an embodiment of present
invention comprises a sole main-part 7 and cloth 8 defined on the
bottom surface of said sole main-part 7, a film being defined
between said cloth 8 and the bottom surface of said sole main-part
7. Said film 9 is made of polyamine ester. Said sole main-part 7 is
made of polyamine ester. Wherein said cloth 8 is defined on the
bottom surface of a front portion of the sole main-part 7 and said
film 9 is defined between the cloth 8 and the front portion. A
cloth 10 is defined on the bottom surface of a heelpiece. A
polyamine ester film 11 is defined between the cloth 10 and the
heelpiece. The inside surface of the front portion defines several
columniform notches 12 and the inside surface of the heelpiece
defines several columniform notches 13.
[0025] Referring to FIGS. 1, the mold for the method of
manufacturing the sole of the present invention is made up of an
upper mold 1 and a lower mold 2. The front portion and the
heelpiece of the inside surface of the upper mold 1 form several
columns 3 and 4 respectively. The front portion and the heelpiece
of the lower mold 2 respectively define two recesses 5 and 6 to
receive the cloth.
[0026] Referring to FIG. 1.about.FIG. 3 together, the method of
manufacturing the sole of the present invention comprises the
following processes: (1) The cloth is daubed with glue and glued
with the polyamine ester film (the polyamine ester film sold by THE
TAIWAN JIEXIN Co. Ltd. is a preferred choice) by a daubing glue
device (the glue device numbered HR-800 which is sold by THE
SHANGHAI ZONGXIN MECHANICAL DEVICE Ltd. is a preferred choice) and
then hot-pressed to connect with the film; (2) Rolling up the cloth
glued with the film and leaving it still for 24 hours, then cutting
the cloth into desired shapes by a cutting knife, putting the cloth
in the recesses of the front portion and the heelpiece of the lower
mold respectively, the surface glued with the film being upward,
the other surface contacting the lower mold; (3) Perfusing the
polyamine ester liquid raw material, which is used to manufacture
the sole, into the sole-shaped space formed by the upper mold and
the lower mold, the bottom surface of the sole close connecting to
the film so that the cloth connects to the sole after molding.
