A rotary bonding apparatus includes a rotatable drum and one or more bonding elements, for example, ultrasonic horn and anvil assemblies, which rotate with the drum. The drum includes a web-supporting surface, and web material which is to be bonded rotates with the drum. The web material is positioned between the bonding elements and the web and bonding elements rotate at the same velocity so that the bonding elements are stationary relative to the web being bonded.

Rotary bonding apparatus and method

An apparatus and method for producing zipper closure bags from a continuous tube which includes advancing the tube along a continuous path for travel with a rotating metering roll, the metering roll having circumferentially spaced apart ports corresponding to a bag width, and a receiving conveyor having vacuum port-equipped sealing bars for receipt of the tube from the metering roll and for providing across seals defining adjacent paths.

Apparatus and method for the production of zipper-type closure bags

A method and apparatus for transversely sealing multi-ply diaper webs including an ultrasonic horn assembly above the web and an anvil assembly below the web, and including orbiting the two assemblies with points of orbit intersection at two spaced apart points on the web and with one of the assemblies being resiliently mounted so as to yield when the two assemblies come in contact during sealing.

Apparatus and method for ultrasonic sealing disposable diapers

In a bag making machine utilizing clamp bar assemblies in combination with a sealing drum, the improved clamp assembly wherein the clamp is coupled to a channel bight, the clamp and channel being related to the conventional pivot shaft by means of a circumferentially-extending pivot pin and with clearance between the channel and pivot shaft.

Clamp assembly for bag producing machine

In a bag making machine utilizing clamp bar assemblies in combination with a sealing drum, the improved clamp bar assembly wherein the clamp bar is related to the conventional pivot shaft by means of a pivot pin floating in a slightly oversized hole.
