Further, the sonic label welding device comprises a head for allowing multiple labels to be assembled under pressure and an anvil for directing the high frequency vibrations. A method of manufacturing a multi-layer care label is also disclosed.

The present disclosure provides an apparatus for forming a stream of individual packets, comprising a folder arranged to form a tubular web structure, a feeder arranged to feed the formed tubular web structure to a nip; a first rotor comprising a first sealing jaw and a knife, a second rotor comprising a second sealing jaw and an anvil, the sealing jaws, the knife and anvil rotating into opposing relation at the nip so as to form a severed, completed packet beyond the nip. The apparatus includes an open ended packet catcher adjacent the first and second rotors, which is arranged to catch the severed, completed packets beyond the nip whereby a stream of packets is established. The packet catcher includes a stripper disposed in a proximal location to at least one of the anvil, the knife and the sealing jaws when the anvil, the knife and/or the sealing jaws are rotated beyond the nip, whereby, should a completed packet stick to any of the anvil, the knife and/or the sealing jaws, the stripper is operative to free the stuck packet from the anvil, the knife and/or the sealing jaw. The present disclosure provides a fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers, the fin sealer being further arranged to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller. A cooling system is also provided, which is operative upon one of the rotors of a cut and seal station.

A sealing element for heat sealing packaging material for producing sealed packages comprises a heating element arranged to heat-seal the packaging material so as to form the sealed packages and a groove arranged to be engaged by a cutting element carried by a counter-sealing element interacting with the sealing element during a cutting operation in which a sealed package is separated from a portion of the packaging material, wherein the sealing element further comprises a resilient element received within the groove so as to prevent clogging particles from entering into the groove.

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.

A sealing device for forming a transversal seal to a tetrahedral packaging container is provided. The sealing device comprises a sealing element and an imprint ruler arranged at a longitudinal distance from the sealing element. The sealing element is configured to provide a top transversal seal to a packaging container while the imprint ruler is configured to provide a transversal imprint to the same packaging container.

Apparatus for forming a pocketed spring unit, comprising a plurality of strings of pocketed springs and at least one cover sheet, comprises welding tools for welding together the pocketing material and the sheet. One of the welding tools is provided with a cutter for cutting the pocket prior to welding. The tool travels in the direction of Arrow A1, so that the cutter penetrates the pocketing material substantially centrally at the circular proximal end face of the pocket. Once inside the pocket, the tool moves axially through the centre of the spring until it reaches the distal end face of the pocket. Before the end face is reached, the piercing member becomes retracted in the direction of Arrow A2, so that the blade does not pierce the distal end face of the pocket.

A welding device (10a; 10b) for welding an outlet element (12a; 12b) to a packaging material (14a; 14b) has at least one anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, has a holding element (20a; 20b) which the anvil (16a; 16b) is arranged on, and at least one welding die (22a; 22b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one support unit (24a; 24b) for supporting the anvil (16a; 16b), comprising at least one movably supported support element (26a; 26b), which is configured to exert a holding force onto the anvil (16a; 16b) in a welding operation state of the welding die (22a; 22b).

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.
