<p>A machine for slicing bread comprises several cutting blades (6) movable towards or away from one another for adjustment of the bread slice thickness. The adjusting mechanism comprises two shafts (1,2) respectively provided with opposite handed threads at one end and linked by a chain (11) and sprockets (7,7.1). A set of guides (3) is mounted on each shaft (1, 2) and joined together by articulated lever arms (4). The end holders of each set engage the threads of their respective shafts and are moved laterally by turning handle (5). The remaining holders are moved proportionately, via the lever arms (4). The blades (6) are mounted in a vertically reciprocable frame (9) by bearings (10) which allow lateral movement of the blades. Members (13) attached to the ends of each blade pass through the guides (3). A similar adjustment mechanism may be provided in a pusher for feeding loaves past the blades. <IMAGE></p> |
