Embodiment Construction

[0052]FIGS. 1, 2 and 3 are isometric view of a machine, constructed in accordance with one embodiment of the present invention, for inflating and sealing pillows in packaging.

[0053] The machine is indicated by the general reference numeral 11 in each of FIGS. 1, 2 and 3.

[0054] The machine 11, as most easily viewed in FIG. 3, comprises a main plate 13 on which various structural and operational features are mounted.

[0055] A support tube 15 is mounted at the upper (as viewed in FIGS. 1-3) of the main plate 13 for supporting a roll 17 of a web of film 19 (see FIGS. 1 and 2).

[0056] Guide tubes 21 and 23 are mounted on the plate 13 below the tube 15. The tubes 21 and 23 serve to guide the web of film 19 from the roll 17 to the operating mechanism 25 of the machine 11. The operating mechanism 25 is described in more detail below.

[0057] The mechanism 25 is illustrated in detail in FIG. 4 and comprises a first film transport station 27, a second film transport station 29, an inflating ...

Abstract

A machine which inflates and seals pillows in packaging is compact in overall size, can be conveniently operated to produce varied lengths of strips of inflated pillow-type packaging as needed, can begin production of inflated pillow-type strip packaging immediately after being held out of a production cycle for some period of time, and applies a heated sealing element directly to and in sliding contact with a web of film to securely seal the inlet port of an inflated pillow while the pillow is under pressure and as the web of film is continuously and uninterruptedly advanced through the machine.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to methods and apparatus for inflating and sealing pillows in packaging. [0002] This invention relates particularly to the construction and operation of a machine which is small enough to be installed for operation on site where articles packaged for transport are placed in shipping containers with protective inflated pillow-type strip packaging. [0003] This invention relates particularly to a machine which is compact in overall size, which can be conveniently operated to produce varied lengths of strips of inflated pillow-type packaging as needed, which can begin production of inflated pillow-type strip packaging immediately after being held out of a production cycle for some period of time and which applies a heated sealing element directly to and in sliding contact with a web of film to securely seal the inlet port of an inflated pillow while the pillow is under pressure and as the web of film is continuously and uninterru...
