    摘要： An apparatus for cutting and heat sealing a pair of overlying heat-sealable panels together comprises a conveyer for moving a pair of superimposed webs of panel material along a linear path and into a cutting and sealing station. A combined cutting and sealing die assembly includes a cutting die for cutting the panels out of the webs and a sealing die for sealing peripheral edges of the superimposed panels together. A heater element is mounted on each of the dies to heat them to their respective cutting and sealing temperatures with the dies being thermally insulated to prevent heat transfer therebetween. A plurality of spring clips attach the dies together to permit thermal expansion of the cutting die relative to the sealing die.

    摘要： An inflation valve, adapted for sealed attachment within a stem of a balloon, includes a valve body defining a longitudinal passage for receiving a fill tube therein, such as a straw. Insertion of an open distal end of the fill tube to a first position within the passage will facilitate communication of a pressurized fluid, such as air or helium, through a fill port defined in the valve body and into the inflation chamber of the balloon. After filling, the fill tube is moved axially forwardly to a second position for sealing-off communication of the open distal end of the fill tube with the fill port.
