Patent number: 10273614Abstract: A sewing machine having a device for manually changing a feed dog (10), including the feed dog (10) and a feed-dog holder (30). The feed-dog holder (30) is disposed in an arm bed (103) that is associated with the sewing machine, and the feed dog (10) is receivable in a clearance (31, 81) of the feed-dog holder (30). The feed dog (10) that is located in the clearance (31, 81) has a support face (15) which may be disposed parallel with the surface of a sewn-product support which may contain a needle-hole plate (113) or be configured as a needle-hole plate (113), the sewn-product support and/or the needle-hole plate (113) may at least partially be formed by the surface of the arm bed (103), and the support face (15) may be received in an opening (140) of the needle-hole plate (113).Type: GrantFiled: January 19, 2017Date of Patent: April 30, 2019Assignee: BERNINA International AGInventors: Alain Capt, Severin Brunner, Gunnar Schlaich, Patric Konner, Andre Stucki, Ioannis Imionidis, Marco Bernegger, Christoph Frei

Patent number: 9869043Abstract: A quilting device (1) comprises a processing unit (5) which is mounted on a frame (3) so as to be manually displaceable in two movement directions (M1, M2) by an operator. A detection device (29) having sensors (27) detects the guiding force which is exerted in these movement directions (M1, M2) by the operator. A controller device (35) controls or regulates, respectively, auxiliary motors (33a, 33b) which support the guiding force, so as to depend on the detected guiding force.Type: GrantFiled: June 23, 2016Date of Patent: January 16, 2018Assignee: BERNINA International AGInventors: Stephan Spengler, Severin Brunner, Roland Beer, Gunnar Schlaich, Ioannis Imionidis

Patent number: 8844454Abstract: The activation for a path and time related motion of a thread cutting and lead-in stitching unit (7) and the thread brake (25) occurs by a cam drive driven by the primary shaft (9) and a cam drum (75) arranged on the upper shaft (17). This way, an absolute synchronization of the elements of the thread cutting and lead-in stitching unit (7), the thread brake (25), and the hook as well as the needle is ensured.Type: GrantFiled: March 14, 2012Date of Patent: September 30, 2014Assignee: BERNINA International AGInventors: Severin Brunner, André Stucki

Patent number: 8757075Abstract: For the continuous drive of a hook of a sewing machine, two drive cams (17) alternately engage in the back of the hook. During the passing of the upper thread loop, the respective drive cam (17) on which the thread would get hung up is out of engagement. The hook is situated in a conical hook race guide and is held therein by magnets.Type: GrantFiled: March 8, 2012Date of Patent: June 24, 2014Assignee: BENINA International AGInventors: Severin Brunner, Niklaus Wacker, Hans Fluckiger, Georg Janouschek, Andre Stucki
