is processed by coating absorbent and by spraying powder adhesive,
while a lower adhesion surface of the midsole is processed by
spraying two-in-one primer, to achieve a one-side cementing. When
the sole and the vamp are attached, an upper surface of the sole is
processed by coating absorbent and by spraying powder adhesive,
while a lower adhesion surface of the vamp is processed by spraying
two-in-one primer, to achieve a one-side cementing. The powder
adhesive is uncharged powder adhesive which is directly sprayed by
a machine, without needing static attachment. The two-in-one primer
is made of reinforcer and glue.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a shoe making method and,
more particularly, to a shoe making method with one-side cementing
by applying powder adhesive.
2. Description of the Related Art
[0002] A shoe structure comprises a sole and a vamp which are
combined together. The sole includes an outsole and a midsole which
are combined together. A conventional shoe making method in
accordance with the prior art shown in FIG. 1 comprises (1) a step
of washing and buffing 10, (2) a step of surface modifying 11, (3)
a step of cementing 12, and (4) a step of adhering 13. In the step
of washing and buffing 10, the outsole and the midsole are washed
and buffed to remove the release agent from the surface of the
outsole and the midsole. Then, the outsole and the midsole are
baked. In the step of surface modifying 11, a modification agent is
coated on the respective adhesion surfaces of the outsole, the
midsole and the vamp, so that the respective adhesion surfaces of
the outsole, the midsole and the vamp have a better adhesive
effect. Then, the outsole, the midsole and the vamp are baked. In
the step of cementing 12, the respective adhesion surfaces of the
outsole, the midsole and the vamp are processed by a cementing
operation. Then, the outsole, the midsole and the vamp are baked.
In the step of adhering 13, the respective adhesion surfaces of the
outsole, the midsole and the vamp are attached so that the outsole,
the midsole and the vamp are adhered to form a shoe structure. When
the outsole and the midsole are attached to form a sole, the step
of cementing 12 performs a two-side cementing operation on the
respective adhesion surfaces of the outsole and the midsole.
However, the cementing operation is performed by a worker, thereby
consuming the manual labor and the working time, and thereby
increasing the cost of fabrication. In addition, when the cementing
operation is performed by the worker, the cement easily spills
outward from the vamp, thereby decreasing the quality of the shoe
product, and thereby increasing the cost of production.

[0069] In the preferred embodiment of the present invention, the
outsole is processed by coating absorbent 22 and by spraying powder
adhesive 220, while the midsole is processed by spraying two-in-one
primer 260 as shown in FIG. 3 to achieve a one-side cementing
purpose. Alternatively, the outsole is processed by spraying
two-in-one primer 260, while the midsole is processed by coating
absorbent 22 and by spraying powder adhesive 220 to achieve the
one-side cementing purpose.
[0070] Referring to FIG. 8, the sole and the vamp are processed and
adhered.
[0071] The method of processing the sole includes:
[0072] (1) washing and buffing 24: the upper surface of the sole is
processed by washing and baking or buffing;
[0073] (2) surface modifying 25: the upper surface of the sole is

[0077] (2) brushing 31: the vamp is processed by brushing
two-in-one primer and baking: and
[0078] (3) adhering 32: the vamp and the sole are attached.
[0079] Referring to FIG. 9, the step of vamp treatment 30
includes:
[0080] (1) surface buffing 301: the adhesion surface of the vamp is
processed by a buffing operation if the vamp is made of leather
material; or
[0081] (2) surface modifying 302: if the vamp is made of PU
synthetic material or net cloth material, the adhesion surface of
the vamp is processed by wiping a modification agent (not shown) to
increase the surface adhesive force thereof.
[0082] Referring to FIG. 10, the step of brushing 31 includes:
[0083] (1) spraying 310: the adhesion surface of the vamp is
processed by spraying two-in-one primer 260; and
[0084] (2) baking 311: the vamp is processed by baking.
[0085] Referring to FIG. 11, the step of adhering 32 includes
attaching 320: directly attaching the sole and the vamp to form the
shoe structure.
[0086] In the preferred embodiment of the present invention, the
sole is processed by coating absorbent 22 and by spraying powder
adhesive 220, while the vamp is processed by spraying two-in-one
primer 260 to achieve a one-side cementing purpose. Alternatively,
the sole is processed by spraying two-in-one primer 260, while the
vamp is processed by coating absorbent 22 and by spraying powder
adhesive 220 to achieve the one-side cementing purpose.
[0087] Referring to FIG. 12, the outsole 40 and the midsole 41 are
combined to form the sole 4, while the sole 4 and the vamp 5 are
combined to form the shoe structure 6.
[0088] Referring to FIG. 13, the midsole 41 is washed. Then, the
modification agent 210 is wiped on the lower surface of the
midsole. Then, the midsole 41 is baked. Then, the two-in-one primer
260 is sprayed onto the lower surface of the midsole 41 by a spray
gun 8 so that the lower surface of the midsole 41 has an adhesive
force. At this time, the two-in-one primer 260 is made of
reinforcer and glue. Thus, the operation of spraying the two-in-one
primer 260 replaces the step of cementing.
[0089] Referring to FIG. 14, the lower adhesion surface of the vamp
5 is buffed. Then, the two-in-one primer 260 is brushed onto the
lower adhesion surface of the vamp 5 so that the lower adhesion
surface of the vamp 5 has an adhesive force.
[0090] Referring to FIG. 15, the lower surface of the midsole 41 is
provided with the two-in-one primer 260, and the upper surface of
the outsole 40 is provided with the absorbent 22 and the powder
adhesive 220. Then, the outsole 40 and the midsole 41 are combined
to form the sole 4. In addition, the lower adhesion surface of the
vamp 5 is provided with the two-in-one primer 260, and the upper
surface of the sole 4 is provided with the absorbent 22 and the
powder adhesive 220. Then, the sole 4 and the vamp 5 are combined
to form the shoe structure 6.
[0091] Accordingly, the reinforcer and the glue are mixed to form
the two-in-one primer which is directly coated on the lower
adhesion surface of the vamp to replace the conventional operation
of labor cementing, so that only one-side cementing operation is
needed, to reduce the labor cementing step, to shorten the
procedures of fabrication, and to save the manual labor. In
addition, when the outsole and the midsole are combined, the lower
surface of the midsole is provided with the two-in-one primer, and
the upper surface of the outsole is provided with the absorbent and
the powder adhesive, so that only one-side cementing operation is
needed to combine the outsole and the midsole. Further, when the
sole and the vamp are combined, the lower adhesion surface of the
vamp is provided with the two-in-one primer, and the upper surface
of the sole is provided with the absorbent and the powder adhesive,
so that only one-side cementing operation is needed to combine the
sole and the vamp. Further, the powder adhesive uses uncharged
powder so that the powder adhesive is directly sprayed by a
machine, without needing static attachment that is necessary for a
conventional powder. Further, the two-in-one primer is directly
sprayed onto the lower surface of the midsole by a spray gun,
without needing labor cementing, thereby preventing the product
from being polluted by labor cementing, decreasing the manual
labor, and reducing the cost of fabrication. Further, when the
outsole and the midsole are combined, and when the sole and the
vamp are combined, the location of the absorbent and the powder
adhesive and the location of the two-in-one primer are
interchangeable to achieve the one-side cementing purpose.
[0092] 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.
