Devices and methods for forming air pillows are described. In accordance with embodiments of the invention, an apparatus for manufacturing air-filled pillows from a tube material includes a plurality of support rollers, a drive means, an injector means, and a sealing means. The plurality of support rollers support a roll of a tube material along an outer circumferential extent of the roll, in which the tube material includes two opposing sheets joined along at least one longitudinal edge thereof. The drive means draws the tube material from the roll along the support rollers, the injector means injects air into an interior space between the two opposing sheets of the tube material drawn from the roll, and the sealing means seals the two opposing sheets together with the injected air entrapped in the interior space therebetween.

1. An apparatus for manufacturing air-filled pillows, the apparatus comprising: a plurality of support rollers to support a roll of material along an outer circumferential extent of the roll, wherein the support rollers are undriven rollers;a driver for drawing the material from the roll along the support rollers, wherein the driver includes upper and lower drive rollers engaging the material to apply tension to the material;an injector wherein, with the material formed as a tube including two opposing sheets, each sheet having first and second longitudinal edges, and the first longitudinal edges of the two sheets joined together and the second longitudinal edges of the two sheets joined together, the injector is configured for injecting air into an interior space between the two opposing sheets of the material drawn from the roll; anda sealer for sealing the two opposing sheets together with the injected air entrapped in the interior space there between. 2. An apparatus for manufacturing air-filled pillows, the apparatus comprising: a support configured for supporting a supply of a material;a drive mechanism configured for drawing the material from the supply;an injector comprising an injection needle, wherein, with the material formed as a tube including first and second sheets, each sheet having first and second longitudinal edges, and the first longitudinal edges of the two sheets joined together and the second longitudinal edges of the two sheets joined together, the injection needle is configured and disposed for making and extending through an aperture in the first sheet for injecting air into an interior space between the two sheets of the material drawn from the roll;a blocking member that is configured to be placed between the first and second sheets, interposed between the injector and the second sheet; anda sealer configured for sealing the two sheets together with the injected air entrapped in the interior space therebetween. 3. The apparatus of claim 2, wherein the drive mechanism comprises drive rollers cooperatively associated to engage the material downstream from the supply. 4. The apparatus of claim 2, wherein: the drive mechanism is configured for driving the tube to position the aperture in a predetermined position with respect to the sealer; andthe sealer is configured to form seal lines on opposite sides of the aperture for joining the first and second sheets together injection location to entrap the injected air. 5. The apparatus of claim 4, further comprising a perforator configured for perforating the tube between the seal lines. 6. The apparatus of claim 2, wherein the sealer comprises a heating element configured to form a seal line joining the two sheets together and to entrap the injected air in the interior space. 7. The apparatus of claim 2, wherein the tube material is made of a polymer. 8. An apparatus for manufacturing air-filled pillows, the apparatus comprising: a plurality of undriven support rollers configured to cooperatively support a roll of material along an outer circumference of the roll;a drive mechanism for drawing the material from the roll that is supported by the support rollers;an air introducer, wherein, with the material drawn from the roll comprising first and second sheets joined along at least one longitudinal edge thereof, the air introducer is configured for introducing air into an interior space defined between first and second sheet portions; anda sealer configured for sealing the first and second sheets together with the introduced air entrapped in the interior space therebetween. 9. The apparatus of claim 8, further comprising a support member disposed between and beneath the plurality of support rollers for supporting the roll when the material remaining has a diameter sufficiently small to fall between the plurality of rollers. 10. The apparatus of claim 8, wherein the plurality of support rollers comprises: first and second of rollers configured to support the roll of material, anda third roller disposed between and beneath the first and second rollers for supporting the roll when the material remaining has a diameter sufficiently small to fall between the first and second rollers. 11. The apparatus of claim 10, wherein the third roller is undriven. 12. An apparatus for manufacturing air-filled pillows, the apparatus comprising: a plurality of rollers configured to cooperatively support a roll of a material along an outer circumference of the roll;a support member disposed between and beneath the plurality of support rollers for supporting the roll when the material remaining has a diameter sufficiently small to fall between the plurality of rollers;a drive mechanism for drawing the material from the roll that is supported by the support rollers;an air introducer, wherein, with the material drawn from the roll comprising first and second sheets joined along at least one longitudinal edge thereof, the air introducer is configured for introducing air into an interior space defined between first and second sheet portions; anda sealer configured for sealing the first and second sheets together with the introduced air entrapped in the interior space therebetween. 13. The apparatus of claim 12, wherein the support member comprises another roller.
