Method of producing a sports glove
Abstract
A method of producing a sports glove includes the steps of: (A)
heating a covering sheet made of a rubbery material; (B) pressing
the heated covering sheet and simultaneously cooling the same so as
to reduce the thickness of the covering sheet and so as to form an
embossed surface on the covering sheet; (C) bonding a fabric layer
to the covering sheet to form a laminate; and (D) cutting and
sewing the laminate to form the sports glove. The embossed surface
of the covering sheet is exposed.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a method of producing a sports
glove, more particularly to a method of producing a sports glove
having a soft covering sheet.
[0003] 2. Description of the Related Art
[0004] A conventional sports glove, such as a baseball glove, is
made from pigskin or cowhide, and has the following drawbacks:
[0005] 1. Because the shape and the thickness of leather made from
the hide or skin of an animal are not uniform, different portions
of leather from a single animal are suitable only for use in
different portions of a sports glove, and many processing steps are
required. This results in complicated production of the
conventional sports glove.
[0006] 2. Since pigskin and cowhide are hard, the conventional
sports glove lacks softness so that it has a low degree of
flexibility and is uncomfortable to use.
[0007] Another conventional sports glove is made from polyvinyl
chloride (PVC), and similarly lacks softness.
[0008] Still another conventional sports glove is made from
polyurethane (PU). This kind of sports glove is too soft, has no
embossed surface, and easily wrinkles and cracks. Hence, this kind
of sports glove wears easily and is not durable.
SUMMARY OF THE INVENTION
[0009] Therefore, the object of the present invention is to provide
a method of producing a sports glove that is capable of overcoming
the aforementioned drawbacks of the prior art.
[0010] According to this invention, a method of producing a sports
glove comprises the steps of: (A) heating a covering sheet made of
a rubbery material; (B) pressing the heated covering sheet and
simultaneously cooling the same so as to reduce the thickness of
the covering sheet and so as to form an embossed surface on the
covering sheet; (C) bonding a fabric layer to the covering sheet to
form a laminate; and (D) cutting and sewing the laminate to form
the sports glove. The embossed surface of the covering sheet is
exposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Before the present invention is described in greater detail,
it should be noted that the same reference numerals have been used
to denote like elements throughout the specification.
[0019] FIGS. 1 and 2 illustrate the steps involved in a method of
producing a sports glove according to the first preferred
embodiment of the present invention These steps will be described
in greater detail below, in combination with FIG. 3.
[0020] In step (A), a covering sheet 2 having a thickness (d) of
about 4 mm is heated to a temperature of about 130.degree. C. The
covering sheet 2 is made of a rubbery material. The rubbery
material is selected from the group consisting of ethylene-vinyl
acetate copolymer (EVA), styrene-butadiene rubber (SBR),
chloroprene rubber (CR), styrene chloroprene rubber (SCR),
thermoplastic rubber (TPR), and thermoplastic elastomer (TPE).
Preferably, the covering sheet 2 is made of EVA or TPE. In step
(B), the covering sheet 2 is pressed by a pressing machine 9 which
has a temperature lower than that of the covering sheet 2. The
pressing machine 9 has upper and lower mold parts 91, 92. The lower
mold part 92 has an embossing surface. The pressing machine 9
operates at a pressure of about 150 kg/cm.sup.2to press the
covering sheet 2 to about 1 mm in thickness, and cold water is
provided in the mold parts 91, 92 to cool the covering sheet 2 to
room temperature. The covering sheet 2 is pressed for about 3
minutes and 50 seconds, and is then released. After the release of
the pressure, the thickness (d) of the covering sheet 2 is
naturally restored to about 1.5 mm, and the covering sheet 2 is
formed with an embossed surface 21.
[0021] In step (C), a fabric layer 3 is bonded to the covering
sheet 2 to form a laminate. This is accomplished in the following
two sub-steps of:
[0022] (i) applying an adhesive to a surface 23 of the covering
sheet 2 which is opposite to the embossed surface 21; and
[0023] (ii) adhering the fabric layer 3 to the surface 23.
[0024] In step (D), the laminate is cut and is sewn to form the
sports glove of the present invention, a cross section of which is
shown in FIG. 3. The embossed surface 21 of the covering sheet 2 is
exposed. From the aforementioned description, the advantages of the
sports glove produced from the method according to the first
preferred embodiment of the present invention can be summarized as
follows:
[0025] 1. The covering sheet 2 and the fabric layer 3 have a
uniform thickness, so that cutting of the produced laminate is
easy.
[0026] 2. The covering sheet 2 is softer as compared to PVC and
leather, so that the sports glove of the present invention has a
high degree of flexibility and is comfortable to use.
[0027] 3. The covering sheet 2 does not easily wrinkle and crack.
Further, wear-resistance of the sports glove of the present
invention is enhanced through the embossed surface 21 of the
covering sheet 2.
[0028] Referring to FIGS. 4, 5, and 6, the steps involved in a
method of producing a sports glove according to the second
preferred embodiment of the present invention is shown to be
similar to the first preferred embodiment. However, in this
embodiment, in step (A), the covering sheet 2 and the fabric layer
3 are heated together, so that the covering sheet 2 is softened,
and in step (B), the covering sheet 2 and the fabric layer 3 are
pressed so that the covering sheet 2 is forced to penetrate the
fabric layer 3, thereby forming a laminate without using an
adhesive. Thus, bonding of the covering sheet 2 is carried out
simultaneously with the pressing of the covering sheet 2 and the
fabric layer 3. The laminate is cooled while being pressed.
[0029] It should be noted that in step (B), by controlling the
pressure used in pressing the covering sheet 2 and by controlling
the pressing time (about 3.5.about.4 minutes), restoration of the
thickness (d) of the covering sheet 2 to about 1.5.about.2 mm is
possible. The aforementioned advantages can be similarly
achieved.
[0030] While the present invention has been described in connection
with what are considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiments but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretations and equivalent arrangements.
