A method for manufacturing a radar cover which covers a radar unit configured to detect surrounding conditions of a vehicle includes: preparing a base having a recessed portion formed of a transparent layer and comprising a colored layer stacked on a portion other than the recessed portion, and a shining member comprising a basal portion including a shining layer on a surface thereof and an edge portion; arranging the base and the shining member such that the edge portion of the shining member and the colored layer of the base are in contact with each other and the shining layer of the basal portion and the recessed portion face each other; and fixing the edge portion and the colored layer to each other.

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.

Described is a heating means for thermally connecting two objects each having a plastic material, wherein, during the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means surrounds the first inner object at least partially along a complete circumferential course around the first inner object, and is located between the first inner object and the second outer object. The heating means has a ribbon-type structure. The ribbon-type structure has an auxiliary heating material, which is inductively heatable, wherein the auxiliary heating material is spatially distributed or arranged along the circumferential course such that an electrical conductivity is interrupted at at least one position along the complete circumferential course around the first inner object. Further described are an arrangement and a system each having such a heating means as well as a method for thermally connecting two plastic objects.

Described is a heating means for thermally connecting two objects each having a plastic material, wherein, in the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means is located between the first inner object and the second outer object. The heating means has a ribbon-type structure, in which a plurality of openings is formed. These openings are dimensioned such that molten-on plastic material of the first inner object and/or of the second outer object can intrude and can connect to molten-on plastic material of the respective other object. Alternatively or in combination, the openings are filled with a plastic material, which can connect to molten-on plastic material of the first inner object and/or of the second outer object. The ribbon-type structure has a ferromagnetic material, which is inductively heatable and which has a Curie temperature that is lower than 460° C. and/or that is adapted to the melting temperature of the first inner object and/or of the second outer object. There is further described a welded arrangement as well as a welding system having such a heating means as well as a method for thermally connecting two objects each having a plastic material.

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 system and method directed to displaying images and presenting the data from the phased array ultrasonic testing (PAUT) inspection of a plurality of welded joints within a welded object. The system includes an engine comprising memory, a graphical user interface (GUI), an export module, a transformation module, and a merger module each operably coupled to one another. The export module is used to extract images and data from the PAUT inspection of the welded joints. The exported information is used by the transformation module to create a multi-dimensional representation of the PAUT inspected welded joint for each joint. The merger module combines the information from the export module and the transformation module into an evaluation report for each PAUT inspected welded joint and assembles the evaluation report into a master report for analysis. The system may be communicatively coupled over a network using a network interface.
