Patent number: 11220019Abstract: A device and a method for cutting a loaf of bread in slices having an input compartment adjacent to a set of parallel oblong blades which can be driven back and forth in their longitudinal direction. A pusher movable between a retracted position in relation to the blades and an end cutting position pushes the bread through the blades. A detector is provided to detect the presence of an object in the access opening of an input compartment which cooperates with the blades' drive to stop the movement of the blades when the presence of an object in the access opening is detected. When the presence of an object in the access opening is detected while the pusher is in its retracted position, the movement of the blades starts and the pusher will be moved from its retracted position to the end cutting position when the object is no longer detected in the access opening.Type: GrantFiled: July 9, 2019Date of Patent: January 11, 2022Assignee: JAC S.A.Inventor: Baudouin Van Cauwenberghe
