Patent ID: 7622014

Claim:
A method for manufacturing an inflatable bladder, comprising the steps of: (a) providing a first film having a first side and a second side; (b) texturizing said first side of said first film in an area corresponding in shape to a pre-defined bladder configuration; (c) providing a second film in contact with said first film, such that said first side of said first film faces said second film, to prevent said first film and said second film from adhering to each other to allow for inflation between said first film and said second film in the area where said first side of said first film has been texturized; (d) adhering said first film to said second film to form a bladder having a sealed periphery in the area where said first side of said first film has not been texturized, and at least one inflatable compartment corresponding in overall shape to said pre-defined bladder configuration in the area where said first side of said first film has been texturized; and (e) cutting along said sealed periphery to yield a bladder having at least one inflatable compartment and a sealed peripheral edge.
