Definitions

  • the present invention relates to methods for making a Goodyear shoe. More particularly, the present invention relates to a method for making a Goodyear shoe, wherein a lower edge of an upper is directly stitched to an inner midsole so as to dispense with such conventional steps as gripping the upper, driving wire nails, and trimming off an excess of the lower edge of the upper.
  • Goodyear shoes Work shoes made and stitched by the Goodyear process are called Goodyear shoes. These shoes, strong and durable, are suitable for use in factories as well as for hunting, firefighting, military actions, etc. where strict safety protection is required.
  • FIG. 1A through FIG. 1D for a conventional manufacturing process of a Goodyear shoe, wherein the manufacturing process (hereinafter referred to as the gripping and wrapping method) includes the steps of: a) placing an inner midsole 11 on a bottom portion of a last 12; b) gripping a lower edge 14 of an upper 13 with lasting pincers 15, wrapping the lower edge 14 of the upper 13 around the last 12, and bonding the lower edge 14 of the upper 13 to an outer surface of an inner welt 16 formed at a lower edge of the inner midsole 11, using hot glue injected from the lasting pincers 15, as shown in FIG.
  • the manufacturing process hereinafter referred to as the gripping and wrapping method
  • the manufacturing process includes the steps of: a) placing an inner midsole 11 on a bottom portion of a last 12; b) gripping a lower edge 14 of an upper 13 with lasting pincers 15, wrapping the lower edge 14 of the upper 13 around the last 12, and bonding the lower edge 14 of the upper 13 to an outer surface of an inner welt 16 formed at
  • the inner midsole in order to sustain the wrapping of the upper and be stitched with the outer welt, the inner midsole must be made of a material which is less likely to twist and deform, such as plastic, and the inner midsole must be formed with the inner welt. Hence, the sole of the resultant Goodyear shoe tends to be so stiff as to prevent comfort of walking.
  • the present invention proposes a novel method for making a Goodyear shoe, wherein the method is intended to prevent the toe cap portion of the upper of a Goodyear shoe from tearing and creasing which may otherwise occur if the conventional gripping and wrapping method is used; to reduce the wasteful use, and therefore cost, of material that may otherwise result from reservation of the gripped section at the lower edge of the upper for use by the lasting pincers; and to alleviate the discomfort of walking that is otherwise attributable to the excessively hard material of which the inner midsole is made.
  • the present invention provides a method for making a Goodyear shoe, wherein the method includes the steps of: stitching together a lower edge of an upper and a peripheral edge of an inner midsole so as to form a coupled section; placing a last into an assembly that results from the previous step and includes the upper and the inner midsole; placing an outer welt on an outer surface of the upper at the coupled section and stitching the outer welt, the upper, and the inner midsole together; placing a filler on a bottom surface of the inner midsole; bonding a thin sole to a bottom portion of an assembly that results from the previous step and includes the filler, the upper, and the inner midsole and stitching the thin sole to the outer welt; and bonding an outsole and performing edge-abrading.
  • the part of the coupled section that belongs to the inner midsole is formed by bending a section of the inner midsole downward, such that a recess is also formed on the bottom surface of the inner midsole.
  • the downwardly bent section functions as the inner welt formed at the bottom portion of the conventional inner midsole while the recess surrounded by the downwardly bent section serves to receive the filler. Therefore, the downwardly bent section of the inner midsole is preferably 3 to 5 mm in length.
  • the inner midsole forms an equivalent of the inner welt at the bottom portion of the conventional inner midsole.
  • the inner midsole of the present invention is a planar plate and can be made of a material such as leather, fabric, and cardboard which are softer than that of the conventional inner midsole.
  • the lower edge of the upper is directly stitched to the inner midsole such that a toe cap portion of the upper will not be torn or wrinkle as is otherwise possible with the conventional gripping and wrapping method. Consequently, Goodyear shoes made by the method of the present invention have higher product yield and are esthetically more desirable than those made by the conventional gripping and wrapping method.
  • the lower edge of the upper is directly stitched to the inner midsole such that reservation of a gripped section is no more required.
  • the method of the present invention makes more economic use of the upper material and incurs lower material costs than the conventional gripping and wrapping method.
  • the lower edge of the upper is directly stitched to the inner midsole so as to eliminate such steps of the conventional gripping and wrapping method as gripping the upper, driving wire nails, and trimming off the gripped section of the upper.
  • the method of the present invention reduces the time and costs of production.
  • a method for making a Goodyear shoe includes the steps of: stitching together a lower edge 32 of an upper 31 and a peripheral edge 34 of an inner midsole 33 so as to form a coupled section 35; placing a last 36 into an assembly that results from the previous step and includes the upper 31 and the inner midsole 33; placing an outer welt 37 on an outer surface of the upper 31 at the coupled section 35 and stitching the outer welt 37, the upper 31, and the inner midsole 33 together; placing a filler 38 on a bottom surface of the inner midsole 33; bonding a thin sole 39 to a bottom portion of an assembly that results from the previous step and includes the filler 38, the upper 31, and the inner midsole 33 and stitching the thin sole 39 to the outer welt 37; and bonding an outsole 41 and performing edge-abrading.
  • FIG. 3 shows how the lower edge 32 of the upper 31 is stitched to the peripheral edge 34 of the inner midsole 33.
  • a section 42 of the inner midsole 33 is bent downward and then bonded and stitched to an inner lateral surface 43 of the lower edge 32 of the upper 31. By doing so, the bond between the upper 31 and the inner midsole 33 is increased, which is highly desirable in making a Goodyear shoe.
  • the downwardly bent section 42 of the inner midsole 33 and the lower edge 32 of the upper 31 are stitched together to form the coupled section 35. Meanwhile, the downwardly bent section 42 surroundinly defines a recess 44 on the bottom surface of the inner midsole 33 for receiving the filler 38.
  • the downwardly bent section 42 functions as the inner welt formed on a conventional plastic inner midsole.
  • the downwardly bent section 42 of the inner midsole 33 has a length of 3 to 5 mm, which is the thickness of a common filler.
  • the inner midsole 33 is a planar plate and is preferably made of a pliable material such as leather, fabric, and cardboard so as to form the downwardly bent section 42.
  • the inner midsole 33 must be a plate having an appropriate thickness at least equal to the thickness of a conventional inner midsole such that, after the upper 31 is stitched to the peripheral edge 34 of the inner midsole 33, a correct shoe shape is formed without deformation.
  • the lower edge 32 of the upper 31 and the peripheral edge 34 of the inner midsole 33 are stitched together before the last 36 is inserted into the assembly of the upper 31 and the inner midsole 33. Consequently, certain steps of the conventional gripping and wrapping method such as gripping the upper, driving wire nails, and trimming off the gripped section of the upper are dispensed with to reduce the time and costs (including material costs) of production while maintaining the functionality of the finished Goodyear shoe.
