  • Publication number: 20240068135
    Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.

  • Publication number: 20100294323
    Abstract: A box-type warewasher includes a housing defining an internal treatment space for receiving wares to be washed and a liquid sump below the treatment space. A wash liquid delivery system includes a wash pump having an input connected to the liquid sump and an output connected to deliver liquid to one or more spray nozzles of the treatment space. A rinse liquid delivery system includes a rinse pump for delivering rinse water to one or more spray nozzles of the treatment space. A condensing system includes a heat exchanger external of the treatment space, and a blower for moving hot moist air from the treatment space across the heat exchanger and back to the treatment space. A controller effects operation of each of the wash liquid delivery system, the rinse liquid deliver system and the condensing system.

  • Patent number: 5119707
    Abstract: A fabricated clamp bar that goes into a channel in a machine roll to hold a knife, anvil, or other tool in the channel. The bar has an internal cavity or chamber in one side of the bar. The chamber has an exposed movable outer side wall placed at the side of the machine roll channel. When the internal cavity or chamber is pressurized with a non-compressible fluid such as grease, the movable side of the chamber is forced outward causing the bar to expand in width, causing the clamping side of the bar to trap the tool to be held in the roll against the side of the channel in the roll of the machine. Also disclosed is the use of an intermediate buffer block between the clamp bar and tool to be held in the roll. Spring loaded members may lightly clamp and pre-position the tool via strategically located holes at each end of the tool until pressure is applied to the fluid.

  • Patent number: 4494741
    Abstract: Apparatus for perforating Z-folding, and further processing long tissue webs to form stacks of Z-folded facial tissues or the like for being packaged in consumer boxes. In one embodiment, two webs are perforated and superimposed at the nip of counterrotating rolls so the perforations of one web are staggered between the perforations of the other web. The webs are Z-folded by vacuum adhering portions of the superimposed webs alternately to the portion of each roll below the nip, drawing the adhered portions back and forth out of the mutual tangent plane forming the nip to start Z-folds. The folds are creased by further means. A continuous stack of Z-folded tissues is formed and can be subdivided into counted stacks of tissue for packaging.
