Abstract: A system comprises a track surface and includes a plurality of motors. The system may further include a plurality of chains. Each chain may be coupled to a motor and may be disposed along a length of the track surface. A plurality of pushers may further be included, with each pusher coupled to a chain of the plurality of chains. In some examples, a controller may be coupled to the plurality of motors.
Abstract: A shrink wrap packaging system has an ultrasonic side sealer. The ultrasonic side sealer contemporaneously slits and welds together at least two separate layers of shrink wrap film. The ultrasonic side sealer is useful in in-line shrink wrap packaging equipment in which a continuous side seal or weld is required to wrap shrink wrap completely around one or more packaged items.
