Abstract
Abstract A moccasin shoe is proposed to be made by a method which comprises cutting the parts of an upper including a vamp, preparing the underside of the vamp for fusing, assembling the back part of the shoe, placing and fixing the thus formed and prepared upper, which does not include a plug, in a mold which is injected with polyurethane or other suitable thermoplastic material to form a sole which is bonded to the underside of the upper and also, by means of an upstanding peripheral flange to the side margins of the upper, removing the upper from the mold and thereafter stitching a plug portion to the upper margin of the vamp.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last; placing and fixing the mounted upper in a mould; successively injecting layers of polyurethane or other suitable thermoplastic material having different physical properties into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 2
Independent Claim
142 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last; placing and fixing the mounted upper in a mould; successively injecting layers of polyurethane or other suitable thermoplastic material having different physical properties into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 3
Dependent Claim
16 words
A method as claimed in claim 1 in which the layers have different textures or colours.
Claim 4
Dependent Claim
21 words
A method as claimed in claim 1 wherein, before the moulding operation, the upper is prepared for a string lasting operation.
Claim 5
Dependent Claim
23 words
A method as claimed in claim 1 in which the heel portion of the sole has a peripheral groove formed by moulding therein.
Claim 6
Dependent Claim
33 words
A method as claimed in claim 1 in which the upper is located on the last by means of pins provided on the last and which pierce the sole part of the upper.
Claim 7
Independent Claim
149 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last; placing and fixing the mounting upper in a mould; injecting polyurethane or other suitable thermoplastic material into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper, a heel portion of the sole having a peripheral groove formed therein by moulding; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 8
Independent Claim
149 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last; placing and fixing the mounting upper in a mould; injecting polyurethane or other suitable thermoplastic material into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper, a heel portion of the sole having a peripheral groove formed therein by moulding; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 9
Independent Claim
146 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last, the last having pins which pierce a sole part of the upper to thereby locate the upper on the last; injecting polyurethane or other suitable thermoplastic material into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 10
Independent Claim
146 words
A method of making a moccasin shoe comprising, in sequence, the following: cutting parts of an upper including a vamp; preparing the underside of the vamp for bonding; assembling the back part of the shoe; mounting the thus formed and prepared upper on a last, the last having pins which pierce a sole part of the upper to thereby locate the upper on the last; injecting polyurethane or other suitable thermoplastic material into the mould to form a sole bonded to the underside of the upper and also, by means of an upstanding peripheral flange having an external peripheral groove formed therein, to the side margins of the upper; removing the upper and sole assembly from the mould; sinking stitching through the groove into the upper to thereby attach the sole to the upper; and stitching a plug portion to the upper margin of the vamp.
Claim 11
Dependent Claim
25 words
A method as claimed in claim 6 or 7 wherein, the sole is formed by successively injecting layers of thermoplastics materials having different physical properties.
Claim 12
Dependent Claim
41 words
A method as claimed in claim 1, 6 or 7 in which there is successively injected a layer of soft, light and relatively flexible material followed by a layer of harder and less flexible material intended to constitute a wearing surface.
Claim 13
Dependent Claim
16 words
A method as claimed in claim 9 in which the layers have different textures or colours.
Claim 14
Dependent Claim
27 words
A method as claimed in claim 8 wherein, a line of stitching is inserted through the upper only above the stitching attaching the sole to the upper.
