Abstract
The disclosure is of a novel method of reducing remnant upon cutting interliner blanks from a plurality of strips of thermoplastic, bias-cut interlining material. The method comprises superposing a portion of the butt ends of the strips in a specific manner and fusing the strips together along a thin line adjacent the superposed butt ends. In the preferred method, butt ends distal to the fusion line are severed simultaneously with fusion to obtain a heat-sealed seam which is hardly detectable, strong and non-interfering with the use of the fused strips as interlining in collars, cuffs and center pleats.

A method of reducing remnant upon the cutting of interliner blanks from a plurality of bias-cut strips of square-woven interlining material, which comprises:
- providing first and second strips of a thermoplastic interlining material, bias-cut from a square-woven sheet, said strips having upper and lower planar surfaces bounded by parallel bias-cut side edges, parallel butt end edges and substantially the same widths;
- superposing a portion of the lower surface of the first strip over a portion of the upper surface of the second strip with a portion of a butt end edge of said first strip superposed over a portion of a butt end edge of said second strip, said superposed butt end edges being aligned with each other and each aligned butt end edge of each strip extending distally beyond one bias-cut side edge of the opposite strip a given distance;
- fusing the first and second strips together along a thin line traversing the width of said strips along a line parallel to said aligned butt end edges, a distance from said aligned butt end edges equal to the distance from the point where said bias-cut edge of one strip intersects with said bias cut edge of the other strip (point 22 in the drawings);
- severing to remove the portion of said strips between said thin line and the aligned butt end edges;
- and
- using the fused strips as a source of interliner blanks.
A method of providing a continuous strip of bias-cut interlining material, which comprises:
- providing first and second strips of a thermoplastic interlining material, bias-cut from a square-woven sheet, said strips having upper and lower planar surfaces bounded by parallel bias-cut side edges, parallel butt edges and substantially the same widths;
- superposing a portion of the lower surface of the first strip over a portion of the upper surface of the second strip with a portion of a butt end edge of said first strip superposed over a portion of a butt end edge of said second strip, said superposed butt end edges being aligned with each other and each aligned butt end edge of each strip extending distally beyond one bias-cut side edge of the opposite strip a given distance;
- Fusing the first and second strips together along a thin line traversing the width of said strips along a line parallel to said aligned butt end edges, a distance from said aligned butt end edges equal to the distance from the point where said bias-cut edge of one strip intersects with said bias cut edge of the other strip (point 22 in the drawings);
- severing to remove the portion of said strips between said thin line and the aligned butt end edges.
