INTRODUCTION PREGIS AIRSPEED 5000
Introduction
The Pregis AIRSPEED 5000 (Figure 1) produces air-filled packing cushions in any quantity, as need­ed. The ability to create packing cushions on demand saves storage space and reduces packaging material waste.
Packing cushions are created in strings of individ­ual cushions. The string can be torn apart at perfo­rations cut between each cushion. The perforation repeats can be 6" or 8" on film webs 8.88" or
10.88". Cushions are created at a constant rate of up to 75 feet per minute (fpm) of film feed. The amount of cushions created per minute will vary with the film cushion size.
Operation
Electrical shock or unexpected machine movement can cause injury. DO NOT operate machine with guards removed or covers open.
For your safety, follow your company’s lockout/tagout policy as required for each task.
The film web is a continuous tube in which there are pairs of cross seals, with a perforation placed bet wee n them, spaced every four to eight inches. The cross seals stop 0.56"-0.62" from one edge of the film. This creates a gap or tube, in the film direction, along that edge of the film.

The film is loaded onto the unwind shaft with the
n
p
seal gap edge facing the inside. The film is then routed around the outside of a spring-loaded roller. This roller maintains film tension by controlling the amount of braking applied to the unwind shaft. The seal gap edge of the film is then guided over the end of the air injection tube. The air injectio tube extends through the seal section, and past the outfeed nip rollers. See Figures 2.

routed around a set of guide rollers, a spring-loaded tensioning roller, and nip rubber rollers. Film is pulled from the roll by the infeed and outfe ed nips. See Figure 2.
The film is captured between the upper and lower sealing belts as it travels through the sealing sec­tion. The sealing head assembly is spring-loaded. The sealing wire presses down against the inside of the upper sealing belt. This downward pressure forces the sealing belts, with the web sandwiched between, against the lower platen. The inflated web of inflated cusions is pulled through the seal section by the outfeed nip roller. See Fig 2
