In certain examples, a machine that forms a web into bags or pouches includes a sealing section through which the web is conveyed in a machine direction. The sealing section is configured to form a lap seal in the web and has an input end configured to receive the web which has a first web section and a second web section. An ultrasonic sealer with a horn and an anvil defines a nip therebetween through which the first web section passes. The ultrasonic sealer is configured to form the lap seal in the first web section. The anvil is positioned between the first web section and the second web section. An output end is configured to dispense the web with the lap seal formed therein.

A method and apparatus for making a structurally resilient package with a desired shape on a vertical form, fill, and seal machine. The method comprises sealing a film to form a back seal; forming a first end seal to form a partially formed first package; flattening a first side of the partially formed first package to form a flat first side; filling the partially formed first package with product; forming a second end seal on the partially formed first package to form a first package from the partially formed first package; flattening the second side of the first package to form a flat second side, wherein the flattening the first side and the flattening the second side occur on a first machine.

An elastic nonwoven material includes a first non-woven fabric including a plurality of rows. Each row has a plurality of adjacent bonds formed therein. The elastic nonwoven material also includes a first elastic strand entrapped between a first pair of adjacent bonds within a first row of the plurality of rows, and a second elastic strand entrapped between a second pair of adjacent bonds within the first row. A third pair of adjacent bonds within the first row is free of elastic material therebetween and is located between the first pair of adjacent bonds and the second pair of adjacent bonds.

A pair of mating sealing jaws for forming a seal between opposing heatsealable surfaces includes a first jaw and a complementary second jaw. Each jaw has a sealing surface that includes at least two peaks separated by a valley. Each peak includes a first face and a second face. A phantom line bisecting the valley defines a first angle between the phantom line and the first face and defines a second angle between the phantom line and the second face such that the first angle differs from the second angle.

A fill packaging machine includes a vertical sealing means for folding a packaging film at its central part and continuously forming a vertical sealed portion at its side edge part to shape into a cylinder, and a lateral sealing means for forming lateral sealed portions in a direction perpendicular to the longitudinal direction of the packaging film. An easy separable sealed portion is continuously formed in the side edge part of the packaging film by the first vertical sealed portion forming section, and a vertical sealed portion having a partial non-sealed portion of a bottle mouth type is formed on the easy separable sealed portion by the second vertical sealed portion forming section. The first vertical sealed portion forming section is a pair of heat sealing rolls or heat sealing plates, a surface of at least one of which is made from an elastic material softer than a metal.

An apparatus for fabricating an elastic nonwoven material generally includes a rotary ultrasonic horn and a rotary anvil positionable in close proximity to the ultrasonic horn. The anvil has a face with a width and a circumferential axis. The face has a plurality of ridges each of which defines a plurality of interspaced lands and notches.

An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module for receiving a first nonwoven fabric, a second nonwoven fabric, and at least one elastic strand therebetween. The second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges includes a first ridge and a pair of second ridges positioned on opposing sides of the first ridge along the circumferential axis. The first ridge defines a plurality of interspaced lands and notches, and the second ridges are configured to sever the at least one elastic strand when in close proximity to the first bonding module.

An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

In the method for producing a tire carcass ply for a vehicle, the ply is wound onto a drum and contains reinforcements running in planes that are radial to an axis of the drum, of which: at least one assembly member (51, 52) mounted such that it can move in relation to the drum brings the ends of the ply together and assembles them by travelling over the ply in a direction (X) parallel to the ends; and prior to assembly, a blade independent of the one or of each assembly member extends between the drum and the ends without extending between the drum and the rest of the ply.
