Method of Automatically Fabricating Pattern Composite Fabric Pieces with Seam Allowance Flaps

Abstract

An automatically fabricated composite material pattern piece is formed with an outer and inner fabric sheet secured together along a pattern seam line by stitching or heat glue fusing. Seam allowance flaps are formed adjacent pattern seam lines and project outwardly from under outer edge portions of the outer fabric sheet to provide for attachment of the composite material pattern pieces together in a specific order to form a finished fabric article.

1 . An automatically fabricated composite material pattern piece comprising an outer and inner fabric sheet secured together along a pattern seam line by fastening means, and seam allowance flaps formed adjacent said pattern seam line and projecting outwardly from under outer edge portions of said outer fabric sheet to provide for attachment of said composite material pattern pieces together in a specific order to form a finished fabric article. 
     
     
         2 . The automatically fabricated composite material pattern piece as claimed in  claim 1  wherein said seam allowance flaps are one of an integrally formed outer edge projecting portion of said inner fabric sheet projecting beyond said outer fabric piece, and a seam allowance fabric material strip secured to an outer edge surface portion of said inner fabric sheet at specific predefined locations and projecting beyond said outer fabric piece. 
     
     
         3 . The automatically fabricated composite material pattern piece as claimed in  claim 1  wherein an insulating material sheet is retained between said outer and inner fabric sheet, said insulating material being one of polyester insulation, wool insulation, acrylic insulation and down insulation material. 
     
     
         4 . The automatically fabricated composite material pattern piece as claimed in  claim 1  wherein said seam allowance flaps are provided with identification means to interconnect said seam allowance flaps to complimentary seam allowance flaps of one or more other pattern pieces to form said finished article. 
     
     
         5 . The automatically fabricated composite material pattern pieces as claimed in  claim 4  wherein said identification means is a printed identification means in the form of a matching code for matching interconnection with other pattern pieces for interconnecting said pattern pieces together. 
     
     
         6 . The automatically fabricated composite material pattern pieces as claimed in  claim 4  wherein said identification means is in the form of a label or patch for matching interconnection with other pattern pieces for interconnecting said pattern pieces together. 
     
     
         7 . The automatically fabricated composite material pattern pieces as claimed in  claim 4  wherein said seam allowance flaps are provided with glue substance for interconnection with associated flaps of other fabric pieces by heat fusing. 
     
     
         8 . The automatically fabricated composite material pattern pieces as claimed in  claim 4  wherein an assembly of said seam allowance flaps are interconnected together by associated ones of said seam allowance flaps by stitches or heat fusing glue to form a fabric article. 
     
     
         9 . The automatically fabricated composite material pattern pieces as claimed in  claim 1  wherein said fastening means is one of stitching and thermal fusing a glue applied to at least one of said seam allowance flaps of a matching pair of seam allowance flaps of matching fabric pieces. 
     
     
         10 . The automatically fabricated composite material pattern pieces as claimed in  claim 9  wherein said composite material pattern pieces are fabric sheets, one of said fabric sheets being an inner liner fabric sheet in which said seam allowance flaps are formed and one or more outer fabric sheets secured to said inner liner. 
     
     
         11 . The automatically fabricated composite material pattern pieces as claimed in  claim 10  wherein an outer surface of said outer fabric sheets which is outermost is provided with a design pattern.
