Title: Kurt Biermann: Innovator in Sewing Technology
Introduction
Kurt Biermann is a notable inventor based in Bielefeld, Germany. He has made significant contributions to the field of sewing technology, holding a total of 5 patents. His innovative designs have improved the functionality and efficiency of sewing machines.
Latest Patents
One of Biermann's latest patents is the top-feed sewing machine with a presser device. This presser device includes a feeder foot, a holding foot, and a link transmission that allows the two feet to cooperate alternately. The feeder foot features a spur that temporarily interacts with a mating surface on the cloth feeder. During the feed phase, the spur is obliquely inclined, which prevents it from pressing against the material being sewn. This design allows for reliable ruffling of an upper layer of sewing material in relation to a lower layer. At the beginning and end of the feed phase, the spur is vertically directed, pressing against the sewing material to enable smooth, tension-ruffle-free sewing, particularly with thin materials.
Another significant patent is the bobbin housing assembly in a sewing machine that includes at least one hook. This sewing machine features a rotating top thread hook that encloses a bobbin housing accommodating a bottom thread. A spring bar is mounted in the base of the sewing machine, with a free end that bears against the bobbin housing. The free end of the spring bar is displaceable by the top thread as it loops. To prevent unwanted displacement or oscillation of the spring bar, a cam is positioned in the base, closely adjacent to the free end of the spring bar, ensuring stability during operation.
