Title: The Innovative Contributions of Donald J Dobbins
Introduction
Donald J Dobbins is a notable inventor based in Waxhaw, NC (US). He has made significant contributions to the field of yarn processing technology, holding a total of 3 patents. His inventions focus on improving the efficiency and effectiveness of yarn blending and winding processes.
Latest Patents
One of Dobbins' latest patents is the "Apparatus and method for blending yarn strands." This invention discloses an apparatus designed to form a blended yarn from multiple yarn strands. The yarns are advanced to contact the surface of a feed roll in a side-by-side arrangement. A guide roll for each yarn strand is positioned upstream of the feed roll, with some guide rolls featuring a circumferential configuration that allows the advancing yarn strands to move relative to each other. This design enables the strands to laterally cross each other on the surface of the feed roll in a predetermined pattern.
Another significant patent is the "Yarn winding apparatus and method." This invention provides a solution for continuously winding a high-speed running yarn. It includes a mechanism for delivering empty bobbins to a winding position and laterally moving full bobbins to a doffing position. An automatic yarn changeover mechanism is also included, which transfers the running yarn from a full bobbin to an empty bobbin without any stoppage or loss of yarn. During the changeover, air jet means are employed to direct an airstream onto the surface of the rotating full bobbin, preventing the severed yarn end from becoming entangled with the adjacent empty bobbin.
