Method for making a surgical drape
First Claim
1. A method of making a series of surgical drapes each comprising a screen portion, and a body portion having a fitted portion, the method comprising:
- advancing a first web along a first longitudinal axis to a cutting and bonding location, the first web being continuous and having first and second long edges generally parallel with the first longitudinal axis;
locating a second web having a first edge such that the first edge of the second web is adjacent the cutting and bonding location and generally perpendicular to the first longitudinal axis;
forming a seam between the first and second webs along a path extending into the second web, the path generally originating and terminating proximate the intersection of the first edge of the second web and the first and second long edges of the first web, respectively;
cutting the first and second webs generally along the path such that a first portion of the second web forms the fitted portion attached to the body portion of a first surgical drape, and a second portion of the second web forms the screen portion attached to the body portion of a second surgical drape in the series of surgical drapes.

Abstract
A surgical drape and a method of simultaneously forming a drape blank of a surgical drape in a single operation having both a screen portion and a fitted portion. A first continuous web forming a body portion of a surgical drape is advanced along a first longitudinal axis to a cutting and bonding location. A second web having first and second long edges generally parallel to a second longitudinal axis is located so that the first long edge of the second web is adjacent to the cutting and bonding location. A curvilinear seam is formed between the first and second webs along a path extending into the second web. The path generally originates and terminates at the intersection of the first long side of the second web and the first and second long edges of the first continuous web, respectively. The seam is cut generally along the path so that a first portion of the second web forms a fitted portion with the body portion of a first surgical drape in the series of surgical drapes. A second portion of the second web forms a screen portion attached to the body portion of a second surgical drape in the series of surgical drapes.

12. A series of surgical drapes, each surgical drape comprising:
-
a body portion having first and second ends; a fitted portion attached to the first end of the body portion along a first curvilinear seam; and a screen portion attached to the second end of the body portion along a second curvilinear seam; the fitted portion, screen portion and first and second ends of the body portion being formed by a process wherein a first web forming the body portion and a second web forming the fitted portion and screen portion are cut and attached along a curvilinear path such that a first portion of the second web forms the fitted portion attached by the first curvilinear seam to the first end of the body portion of a first surgical drape, and a second portion of the second web forms the screen portion attached by the second curvilinear seam to the second end of the body portion of a second surgical drape in the series of surgical drapes. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A surgical drape comprising:
-
a body portion having first and second ends; a fitted portion attached to the first end of the body portion along a first curvilinear seam, the fitted portion having a shape; and a screen portion attached to the second end of the body portion along a second curvilinear seam, the second curvilinear seam being formed along a cut-out edge portion of the screen portion defining a shape cut out of the screen portion corresponding to the shape of the fitted portion. - View Dependent Claims (20, 21, 22, 23, 24, 25)
