Claim of US Patent No. 10,362,833

1. A method of manufacturing a bladder element comprising:forming at least one of a first polymeric sheet, a second polymeric sheet, or a third polymeric sheet with a contoured surface profile;
after said forming, stacking the first polymeric sheet, the second polymeric sheet, and the third polymeric sheet in a mold assembly so that the second polymeric sheet is between the first polymeric sheet and the third polymeric sheet; and
applying fluid pressure in the mold assembly:
between the second polymeric sheet and the third polymeric sheet, forcing a first surface of the second polymeric sheet into contact with an inner surface of the first polymeric sheet, or
between the first polymeric sheet and second polymeric sheet, forcing a second surface of the second polymeric sheet into contact with an inner surface of the third polymeric sheet, or
between the first polymeric sheet and second polymeric sheet, and between the second polymeric sheet and the third polymeric sheet, forcing both the second surface of the second polymeric sheet into contact with the inner surface of the third polymeric sheet, and the first surface of the second polymeric sheet into contact with the inner surface of the first polymeric sheet.
