Latest Patents

Two of Ronshaugen’s latest patents focus on slider-bar processing and carrier design.

“Method and Assembly for Grinding and/or Cutting a Slider Bar on a Lapping Carrier” describes a process in which slider bars are attached to a component of a multi-component carrier. The carrier is connected to a lapping arm, and the bars are lapped before the relevant carrier component is attached to a grinding or cutting machine. The method then applies at least one grinding or cutting operation to the bars.

“Lapping Assembly or Process Utilizing a Bar Stack Extender” describes an extender that removably connects one or more slider bars to a processing machine or tool. In illustrated embodiments, a tongue-and-groove connection couples the extender to a holder structure. The extender also includes lengthwise strips of reduced thickness, designed to control or transfer bending to bars connected along its proximal edge.

Career Highlights

Ronshaugen’s patent portfolio reflects a focus on manufacturing processes and tooling for slider bars. The disclosed methods combine lapping with subsequent grinding or cutting, while the extender design offers a removable connection and a way to manage bending during processing. These approaches address practical aspects of precision component fabrication.
