20090243135 | METHOD AND APPARATUS FOR MAKING FOAM-IN-PLACE CUSHIONS WITH SELECTIVE DISTRIBUTION OF FOAM - A method and apparatus for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape. | 10-01-2009 |
20090308965 | Machine, method, and system for severing a web - A machine, system and method for severing a web having a series of containers, wherein the containers are spaced apart and linked together by a series of connectors disposed between the containers. The machine generally includes a rotary device having a plurality of spaced-apart standoff members extending radially outwards to contact the web at the connectors such that rotational movement of the rotary device causes movement of the web; a severing mechanism including a movable severing device that is adapted to urge the web against one of the standoff members to thereby effect severance of the web; and a control system comprising an operator interface to allow a specified number of containers to be selected for severance from the web. | 12-17-2009 |
20100043353 | Inflatable Mailer, Apparatus and Method for Preparing the Same - The invention is an inflatable mailer having a liner that can be inflated at the point of use. The liner includes a series of inflatable chambers that are in fluid communication with a common channel. A controlled volume of gas is disposed in the liner. The gas is sufficient to inflate the common channel but is not sufficient to appreciably inflate the inflatable chambers. As a result, the inflatable mailer is in a relatively compact state. The invention includes an apparatus for inflating the mailer. The apparatus includes a nip for moving the controlled volume of gas into the common channel; an inflation nozzle adapted to pierce the inflated common channel and introduce a second portion of gas into the liner until the liner is inflated to a desired level; and a sealing device to seal the inflated liner. | 02-25-2010 |
20110167772 | Heat-seal device - A heat-seal device generally includes a heat source, a thermal conductor, which encapsulates at least a portion of the heat source and is capable of transferring heat from the heat source, and a thermal insulator, which substantially surrounds the thermal conductor but leaves a portion thereof exposed, the exposed portion of the thermal conductor providing a heat-seal contact surface, which is adapted to be brought into contact with a material to be sealed. | 07-14-2011 |
20120080133 | Heat-Seal System and Method - A heat-seal device generally includes a heat source, a thermal conductor, which encapsulates at least a portion of the heat source and is capable of transferring heat from the heat source, and a thermal insulator, which substantially surrounds the thermal conductor but leaves a portion thereof exposed, the exposed portion of the thermal conductor providing a heat-seal contact surface, which is adapted to be brought into contact with a material to be sealed. | 04-05-2012 |
