An apparatus for transferring articles such as absorbent cores or disposable diaper chassis components from a rotary mechanism, such as a pad turner, to a linear mechanism, such as a conveyor, for further processing. The invention provides a device for picking an article from the outside of a toroidal surface, thence extending transversely under tension the article to be transferred so that at the point of deposition the article is held flat and at full length. Further, the invention allows for apparatus to match the velocity of both the first and second transfer points, even if these velocities are not the same. The device is of particular benefit where an article to be transferred is subject to internally biasing elastic forces.

The multi-layer film structure having an inner sealing layer which comprises metallocene resin, a core which includes polypropylene copolymer and an outer layer and wherein the multi-layer film structure has a thickness within a range between about 50 and 70 microns (2.0-2.75 mil). By utilizing this thin film with specific properties the sealers may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10° C. to 15° C. and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This results in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength. The machine accomplishes better seals with less energy, requires less downtime for roll changes and maintenance and increase throughput.

A method for producing inflated dunnage on the site of use, comprising providing, in web form, a plurality of preformed plastic bags, each of the bags comprising two plastic sheets in facing relationship and sealed along three edges with one edge remaining open.

A plurality of sealed inflated bags is separated from the web and placed in a carton to serve as dunnage. The bags have a slip resistant outer surface which causes the bags to interlock in the carton and better protect object therein from shock.

An approach for sterilizing microorganisms at a target object employs a flashlamp system including means for generating pulses of light, and for deactivating microorganisms within the target object by illuminating the target object with the pulses of light having been generated; a photo-sensitive detector positioned so as to receive a portion of each of the pulses of light as a measure of an amount of light illuminating the target object, for generating an output signal in response thereto; and a control system, coupled to the flashlamp system and the photo-sensitive detector, for determining, in response to the output signal, whether the pulses of light are sufficient to effect a prescribed level of deactivation of microorganisms at the target object. In accordance with this approach sterilizing microorganisms involves steps of generating a pulse of light; deactivating microorganisms at the target object by directing the pulse of light having been generated at the target object; receiving a portion of the pulse of light as a measure of an amount of the pulse of light illuminating the target object; generating an output signal in response to the receiving of the portion of the pulse of light; and determining, in response to the generating of the output signal, whether the pulse of light is sufficient to effect a prescribed level of deactivation of microorganisms at the target object.
