A system and method for producing a disposable undergarment, with the lateral edges of the undergarment bonded by means of an ultrasonic horn. When a blank is formed for an individual undergarment, the lateral edges of opposing edges of the blank will form the seam. When the edges are sealed together, a seam is formed. The individual undergarments may be later separated along the seams.

A sealing bar assembly for a packaging machine includes a mounting frame, first and second sealing bar carriages carried by the mounting frame, at least one of the first and second sealing bars being movable with respect to the mounting frame, first and second sealing bars mounted, respectively, to the first and second sealing bar carriages and movable therewith, the first and second bars including, respectively, first and second opposed sealing surfaces, at least a first electromagnet assembly arranged adjacent to the first sealing bar, and a controller configured to selectively energize the first electromagnet assembly to move the first and second opposed sealing surfaces into and out of engagement across a web of packaging material passing therebetween.

A substrate assembly is mechanically deformed to form various products. In part, the substrate assembly may advance toward a bonder apparatus. The bonder apparatus rotates about a longitudinal axis and includes a plurality of manifolds. The plurality of manifolds allow for substrate assemblies including different process product pitches to be processed on a single bonder apparatus.

A method and apparatus for mechanically deforming a substrate assembly. The substrate assembly may advance toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation and is configured to radially traverse based on the process product pitch of the substrate assembly. The bonder apparatus may include a plurality of manifolds positioned about the axis of rotation. The substrate assembly may be advanced onto the bonder apparatus such that the substrate assembly is disposed on the plurality of manifolds. The manifolds may heat fluid and release the same onto the trailing edge portion and the leading edge portion of the substrate assembly. The heated portion of the substrate assembly may then be bonded forming a seam.

The invention relates to a horizontal transverse sealing station (10a-b), in particular for a horizontal tubular bag machine (12a-b), for producing transverse sealing seams (14a-b) on at least one film tube (18a-b) transported in a continuous, at least essentially horizontal transport direction (16a-b), comprising a transverse sealing station base (20a-b) fixedly connected to a packing machine (22a-b), a transverse sealing unit (24a-b), and at least one sealing jaw pair (28a-b) movably mounted on the transverse sealing unit (24a-b) and formed by two sealing jaws (26a-b), the sealing surfaces (30a-b) of which come closer to each other during a sealing process in a sealing movement (32a-b), which relative to the transverse sealing unit (24a-b) is provided with at least one movement component (34a-b) in the transport direction (16a-b), in order to seal material layers (36a-b) of the film tube (18a-b) between the sealing surfaces (30a-b) by way of heating and/or applying pressure, and to remove again at the end of the sealing process. According to the invention the transverse sealing unit (24a-b) is driveably mounted on the transverse sealing station base (20a-b) in a displacement movement (38a-b) that is at least substantially parallel to the transport direction (16a-b).

An ultrasonic welding device includes a rotary support mechanical assembly rotatable about a rotation axis and operable to support a sheet over a circumference centered on the rotation axis, the sheet being continuously supplied; a horn and an anvil attached to the rotary support mechanical assembly to thereby revolve about the rotation axis and sandwich the sheet supported over the rotary support mechanical assembly to weld the sheet; a cam drum and a cam follower for driving the anvil in such a manner that the anvil moves relative to the horn; a holding member body; and a power transmission mechanism for distributing a power generated by the cam and the cam follower in such a manner the power is transmitted to the anvil and holding member body in opposite directions.

The present invention is directed to a heat-sealing apparatus of a flow wrapper machine which facilitates efficient, reliable and versatile operation. Notably, the apparatus includes multiple ring gears driven by multiple servo motors in a desirably compact configuration, with the arrangement including quickly removable heat-sealing die heads for efficient operation and service. The improved drive mechanism facilitates more accurate heat-sealing head placement, smoother operation, controlled stops, independent temperature control, and continuous running through die jams. Also included is a four-bar link on the heat-sealing head for opening and closing the heat-sealing dies.

A variable size welder that facilitates welding of polymer quadrilateral frame structures. The welder includes at least two parts conveyors that deliver parts from a remote location and parts staging stations and end heaters on each of four sides of the variable size welder. A centrally located four corner clamping structure and at least two robotic parts movers are configured to reach the at least two parts conveyors and also to reach the parts staging stations and end heaters. The at least two robotic parts movers are further configured to reach at least a portion of the four corner clamping structure.
