Title: The Innovative Mind of Sixten H. Lejdegard
Introduction
Sixten H. Lejdegard, residing in Ramnas, Sweden, is a notable inventor with an impressive portfolio of seven patents. His innovative contributions primarily focus on screw application technologies, which streamline fastening processes across various industries.
Latest Patents
Lejdegard's latest inventions include a Screw Applicator and a Screw Package. The Screw Applicator is a sophisticated screw tightening apparatus that features a motor-driven tool and a screw magazine attached to a strip-like carrier. This inventive design allows screws to be advanced one at a time to a position where a motor-driven bit engages and applies the screw. The mechanism includes a bell crank with a spring arm that advances the screw strip and a drive arm that is activated by a plunger to prepare the screw for application. Notably, a punch and die structure cuts a washer-like portion from the carrier strip to ensure a secure fit as the screw is applied.
The Screw Package is another of Lejdegard's significant inventions, consisting of a carrier strip through which screws extend transversely. The design ingeniously incorporates holes that correspond closely to the shank diameter of the screws, allowing for effective and efficient application. As each screw is driven into place, a washer made from the carrier strip is separated and secured under the screw head, enhancing the overall fastening integrity.
