The conductive element comprising at least one first and one second contacting tabs each integral with said conductive structure; each of said contacting tabs protruding transversally from a prevalent development surface of the conductive structure towards the supporting substrate (206) for defining a terminal contacting end. The heating head (700) comprising a first and second electric terminals respectively engaged with said first and second contacting tabs; each of said electric terminal is configured for stably constraining opposite faces of the respective contacting tab which define the thickness of said tab.

The invention relates to ultrasonic welding of industrial fabrics. Specifically, the invention relates to methods for ultrasonically welding the seam area of industrial fabrics using a textured horn and/or anvil. The fabric edges are overlapped as woven or one or both edges can have some warp or weft yarns raveled out. The method involves ultrasonically bonding the overlapped fabric edges, reducing the caliper of the two stacked edges to match the body caliper of the fabric itself. The bonded area can then be perforated using laser or other mechanical means to produce a seam having the same woven texture and permeability (air and/or water) as the body of the fabric.

A method for quality control of a packaging system is provided. The method comprises receiving a first record of packaging quality parameter data related to a first packaging quality parameter for a package being assessed, determining a second packaging quality parameter based on said first record, requesting a second record of packaging quality parameter data related to said second packaging quality parameter, and receiving said second record.

A system for manufacturing a balloon envelope includes a table component and a sealing component. The sealing component includes a first level and a second lower level. The first level further includes first and second platforms. The first platform can provide a work area for sealing respective first and second sheets of material together to form a sealed edge and the second platform may provide a work area for sealing the second sheet of material and a third sheet of material together. The first, second, and third sheets of material respectively form first, second, and third gores of the balloon envelope. The sealing component may be configured to move along length of the first platform and to apply a heat seal to bond the first sheet of material to the second sheet material and form a sealed edge.

A pressure jaw assembly (1) for a sealing jaw arrangement of a filling machine. The pressure jaw assembly (1) comprises a pressure jaw frame (10), a pressure element (20) arranged to be moved relative the pressure jaw frame (10), a compressing means (40) arranged at least partly between the pressure jaw frame (10) and the pressure element (20). The compressing means (40) is arranged to influence the relative movement between the pressure element (20) and the pressure jaw frame (10). The pressure jaw assembly (1) further comprises a guide (50, 52) for guiding the pressure element (20). The guide (50, 52) is connected to the pressure jaw frame (10), and the guide (50, 52) is arranged externally of the pressure element (20).

A method for quality control of a packaging system is provided. The method comprises receiving a record of packaging identification data, wherein the record of packaging identification data being related to a package. Next, identifying and receiving a record of machine data using said record of packaging identification data, wherein said record of machine data being related to a machine set up used when producing said package. Thereafter, identifying a packaging quality parameter to be checked based on said record of machine data, and requesting a record of packaging quality data related to said packaging quality parameter.

The present invention discloses a household vacuum sealer and a bag-cutting sealing method. In the household vacuum sealer, at least one cutter device is slidably mounted on the upper hood, a heat-seal bar and an evacuative groove are arranged at the front side of the upper portion of the lower hood, the upper hood or the lower hood is provided with a bag receiving chamber, a detachable automatic rollback shaft is rotatably mounted in the bag receiving chamber, the elastic rollback mechanism for automatically rolling the rollback shaft back and the elastic unidirectional locking mechanism for locking the automatic rollback shaft are mounted at the end portion of the automatic rollback shaft: the cutter device protrudes from a bottom surface of the upper hood, and the cutter moves at one side of the heat-seal bar or one side of the evacuative groove back and forth after the upper hood is locked onto the lower hood, for cutting off the bag pressed tightly between the upper hood and the lower hood. The present invention has a simple structure since the bag is cut at the original heat-seal bar or the evacuative groove of the lower hood, which is more convenient. Subsequent to cutting off the bag, the vacuum packaging bags are automatically rolled back after the hood is opened, which reduces the number of operation steps for the user, and exhibits ease and quickness of operation.
