Method for adhesion of surface skin of ball
Abstract
A method for adhering a surface skin of a ball, which uses a
means that is free of solvent and involves no solvent, and which is
friendly to the environment, creates no odor, poses no danger of
fire attributable to catalysts, eliminates the solvent drying time
and space that would otherwise be required, and requires no
particular skill. In a ball, an adhesive layer 2 is provided on the
outer surface of a carcass 1, and a surface skin 3 is placed over
the adhesive layer 2; or the adhesive layer 2 is provided on the
inner surface of the surface skin 3, and the surface skin 3 is
placed over the carcass 1; and adhesion is performed using a means
free of solvent. Here, the carcass 1 includes the adhesive layer 2
provided over a tube 1a or includes a reinforcing layer 4 provided
over the tube 1a, and the adhesive layer 2 provided over the
reinforcing layer 4.

Claims
1. A method for adhering a surface skin of a ball, comprising the
steps of providing an adhesive layer on an outer surface of a
carcass and placing a surface skin over said adhesive layer, or
providing an adhesive layer on an inner surface of a surface skin
and placing said surface skin over a carcass; and then performing
adhesion with a means that is free of solvent.
2. The method for adhering a surface skin of a ball according to
claim 1, wherein the carcass is produced by either providing an
adhesive layer over a tube or providing a reinforcing layer over a
tube and providing an adhesive layer over said reinforcing
layer.
3. The method for adhering a surface skin of a ball according to
claim 1, wherein the adhesive layer is one selected from an
adhesive film, a thermal adhesion film, a powdered adhesive agent,
and a non-solvent adhesive agent.
4. The method for adhering a surface skin of a ball according to
claim 1, wherein the means free of solvent is heating, pressing, or
rubbing.
Description
TECHNICAL FIELD
[0001] The present invention relates to a method for adhering a
surface skin of a ball.
BACKGROUND ART
[0002] Conventional balls used for sports include a bonded ball in
which a surface skin is provided on a reinforcing layer, a rubber
ball in which a rubber layer is provided on a reinforcing layer,
and a stitched ball in which a surface skin and a valve portion are
fixed together.
[0003] On the insides of these balls is what is known as a carcass,
comprising a rubber member called a tube, which has a valve and
holds the air inside to become spherical when filled with air, and
a reinforcing layer, which covers the tube.
[0004] A surface skin is bonded over this carcass by way of using a
solvent. But the use of a solvent for this purpose accompanies
several problems. There is a solvent odor and the danger of fire,
which creates an unhealthful working environment; and the solvents
take time to dry, take up space while drying, and require
adjustment of the viscosity, which requires considerable skill.
[0005] In view of this, the present invention discloses and
provides a method for adhering a surface skin of a ball, which
supplants conventional methods for adhering a ball surface skin,
and which does not use a solvent, that is, which performs adhesion
by a means that is free of solvent; and it is, therefore, friendly
to the environment, results in no odor, poses no risk of fire
attributable to solvents, eliminates the solvent drying time and
space that would otherwise be required, and requires no special
skill.
DISCLOSURE OF INVENTION
[0006] With the present invention, in adhering a ball surface skin,
an adhesive layer is provided on either the surface skin or the
carcass, and the carcass and surface skin are adhered together. The
carcass is such that either an adhesive layer is provided over a
tube, or a reinforcing layer is provided over a tube and an
adhesive layer is provided over the reinforcing layer, while the
adhesive layer is selected from an adhesive film, a thermal
adhesion film, a powdered adhesive agent, and a non-solvent
adhesive agent.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a partially omitted cross sectional view of an
embodiment of the present invention.
[0008] FIG. 2 is a partially omitted cross sectional view of
another embodiment of the present invention.
[0009] FIG. 3 is a partially omitted cross sectional view of yet
another embodiment of the present invention.
[0010] As for the reference numerals used in all the drawings, 1 is
a carcass, 1a is a tube, 2 is an adhesive layer, 3 is a surface
skin, and 4 is a reinforcing layer.
BEST MODE FOR CARRYING OUT THE INVENTION
[0011] An embodiment of the present invention will now be described
with reference to FIG. 1, which illustrates a method for adhering a
surface skin of a ball. In a ball, an adhesive layer 2 is provided
on the outer surface of a carcass 1, and a surface skin 3 is placed
over the adhesive layer 2; or the adhesive layer 2 is provided on
the inner surface of the surface skin 3, and the surface skin 3 is
placed over the carcass 1; and then adhesion of the surface skin to
the carcass is performed by a means that is free of solvent.
[0012] As shown in FIG. 2, the carcass 1 comprises the adhesive
layer 2 provided over a tube 1a; or, as shown in FIG. 3, it
comprises a reinforcing layer 4 provided over the tube 1a, and the
adhesive layer 2 provided over the reinforcing layer 4.
[0013] Further, the adhesive layer 2 used in the present invention
is selected from an adhesive film, a thermal adhesion film, a
powdered adhesive agent, and a non-solvent adhesive agent.
[0014] The surface skin 3 is made from natural leather, synthetic
leather, natural rubber, synthetic rubber, natural sponge rubber,
synthetic sponge rubber, natural fabric, synthetic fabric, or the
like.
INDUSTRIAL APPLICABILITY
[0015] Because an adhering means that requires no solvent is used
in the present invention, a uniform adhesive layer is obtained on
the carcass and surface skin; and when an adhesive film is used for
the adhesive layer, the carcass and surface skin are adhered
together. The adhesive film can be punched out in any shape
desired, and there is no oozing of solvent; and since no solvent is
used, it is also friendly to the environment, creates no odor,
poses no danger of fire attributable to catalysts, and eliminates
the solvent drying time and space that would otherwise be
required.
[0016] Also, because the adhering means that requires no solvent is
employed, there is no need to deal with changes over time in the
relationship between the solvent and the adhesive layer as in the
past, nor is there any danger of curing modification; and therefore
no particular skill is required, which lowers the cost entailed.
Thus, the present invention is extremely beneficial in terms of
both safety and ease of work.
