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.
