US 4,047,951 A · Marker making methods for cutting fabric patterns

Abstract

A method of making both full size and miniature replicas of patterns on photographic film from conventional paperboard clothing patterns. The full size clothing pattern replicas on film may be arranged directly on a conventional marker sheet in place of the paperboard clothing patterns. The miniature pattern replicas may be arranged on miniature marker sheet replicas constructed to the same scale as the miniature pattern replicas. The layout may be copied and the copy of the miniature pattern layout may be used as a guide in laying out full size patterns or pattern replicas on a marker sheet or the copy may be enlarged and reproduced to its original scale on a light sensitive marker sheet. The clothing pattern replicas may be formed with integral blocking borders or blocking lines.

Dependent claims

A method of cutting pieces of fabric for use in the manufacture of clothing, including the steps of:

reproducing a full size image of a clothing pattern on a light sensitive film by photographic contact printing of said pattern and said film and then developing said exposed film to provide a film replica of said pattern having an image corresponding to that of said pattern with said image being at least partially surrounded by a border,
positioning a plurality of said film replicas on a light sensitive marker sheet with said images arranged on said marker sheet so as to provide the most efficient utilization of the fabric to be cut using said marker sheet,
exposing said film replicas and said light sensitive marker sheet to a source of light,
developing said exposed light sensitive marker sheet to provide a marker sheet having a plurality of closely spaced marker images thereon, and
placing said marker sheet on a lay of fabric and cutting said lay of fabric into pieces of fabric by cutting along the outlines of the marker images on said marker sheet.

A method of cutting pieces of fabric for use in the manufacture of clothing, said method including the steps of:

establishing at least an outline of a full size clothing pattern against a suitable contrasting background,
photographically reproducing an image of at least said clothing pattern outline on a reduced scale on a light sensitive photographic film to provide a miniature film replica of said pattern,
removing at least any unnecessary opaque portions of said developed miniature film replica surrounding said image,
positioning a plurality of said miniature film replicas on a miniature replica of a marker sheet with said images of said miniature film replicas arranged on said marker sheet replica so as to provide the most efficient layout of said images for cutting fabric using a full size enlargement of said miniature replicas and said marker sheet,
positioning a sheet of light sensitive film against said layout of miniature film replicas,
exposing said layout of miniature film replicas and said light sensitive film to a source of light,
developing said exposed light sensitive film to provide a miniature marking sheet film having a plurality of closely spaced marker images thereon,
projecting an enlargement of said exposed film onto a full size light sensitive marker sheet, developing said exposed full size light sensitive marker sheet to provide a marker sheet having a plurality of full size closely spaced marker images thereon, and
positioning said marker sheet on a lay of fabric and cutting pieces of fabric from said lay by cutting along the outlines of said marker images on said marker sheet.
