  • 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.

  • Patent number: 3941014
    Abstract: A precision heavy duty indexer characterized in that the indexing member is hydraulically actuated to a locking position whereat it is locked to the indexer housing in desired precise indexed position without circumferential or radial play and without transmission of torque load to the indexer drive means or without transmission of radial load to the indexing member-housing bearings; and is hydraulically actuated to unlocking position whereat it is released from said housing for indexing movement and whereat it is engaged by said drive means operative to index the indexing member to the next indexed position. The indexer herein is further characterized in that the indexer drive means comprises a hydraulic motor driven worm which meshes with a worm wheel having driving engagement with said indexing member, said worm having a sensor-counter thereon to de-energize said hydraulic motor when the indexing member has been indexed through a predetermined angle from one indexed position to the next.
