摘要:
Apparatus and a process for dividing heat-shrinkable plastic film into different temperature regions within a shrink wrap oven including a movable platform; a cylindrical tube immovably mounted within the oven in the direction of movement of the platform and including a platform for supporting a portion of the heat-shrinkable plastic film and a slit running the length of said cylindrical tube; a package covered with heat shrinkable plastic film and including that portion of the heat-shrinkable plastic film resting on the platform adjacent the cylindrical tube; an electric fan mounted at the opposite end of the cylindrical tube containing the platform and sucking ambient air through the cylindrical tube to cool that portion of the heat-shrinkable plastic film as the heat-shrinkable plastic film is tightly shrunk around the package.
摘要:
A container/package of filamentary material wound in a coil and encased in heat shrinkable film with a payout tube extending through a payout hole in the container/package, the heat shrinkable film is formed as a pouch having an open end into which the coil is inserted; one end of the shrink wrap material is folded back on itself to form a hand-held cutout; the open end of the pouch is sealed and the shrunk wrap material is heated to seal the coil in the shrunk wrap material while isolating the hand-hold cutout; and the container/package is thus formed with a heat shrunk pouch tightly containing the coil of filamentary material and an attached portion not exposed to heat and not shrunk.
