With a total of 4 patents to his name, Bertsch's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a "Selvedging device with threading nozzle and tuck-in needle." This innovative pneumatic selvedging device allows for the weft yarn end to be temporarily retained by a threading nozzle. A tuck-in needle then takes over the retained weft yarn end for drawing it in between the warp yarns of a loom. The threading nozzle is mounted on a retaining arm, which is pivotally mounted on a shaft within a casing above the cloth and near the beating-up edge for the weft yarn. Additionally, a second drive shaft is mounted in the same casing to drive the tuck-in needle. The design includes a common drive shaft that operates both the tuck-in needle and the threading nozzle via cams and cam follow-up levers. Furthermore, a shears may be mounted on the retaining arm, actuated by a link connected to a pivotal blade of the shears.
Another significant patent is the "Tuck-in needle and a pneumatic selvedge-forming device for a loom." This device features a tuck-in needle with a wedge-shaped cross-section at the end part that is introducible into the shed. The needle has an elongate yarn entry aperture, allowing for easy threading of the weft yarn end with reduced blowing pressure from a threading nozzle. The design enables the needle to make pivoting movements very close to the shed apex, ensuring efficient tucking of the weft yarn end.
