The specimen arm is made of two segments which are secured to each other via a lockable hinge assembly. The lockable hinge assembly uses a hinge between the two segments as well as a locking mechanism. When locked, the two segments are in a fixed relationship which causes the specimen to be forced through the knife by the action of the motor. When the locking mechanism is unlocked, the segment of the specimen arm holding the specimen is able to rotate (“float”) around the hinge; thus allowing the specimen to be sliced by the knife as gravity pulls the segment downward.

  • Patent number: 7089840
    Abstract: A food slicing apparatus and components where the apparatus includes a frame and a pivotally mounted carriage. The frame mounts a height adjustable conveyor system while the carriage hosts a latch for a slice thickness adjustment cam. The carriage also supports a drive system which precisely moves a food transporting tube assembly over a base, such as pizza dough, while food is cut by a laterally moving blade mounted around two drums, one of which is adjustable to change tension in the blade. The blade is further supported by a blade guide which also guides the sliced food to the pizza dough base. The drive system includes a servomotor, a group of gears, a crank connected to the gears, a cam roller and a cam follower plate with a slot. The cam follower plate is connected by a quick connect and disconnect connector to the food tube assembly. The result is a compact, efficient slicing apparatus with a small footprint that is usable in a food processing line.

  • Patent number: 6952989
    Abstract: A food product cutting apparatus that makes a substantially horizontal cut through food product being delivered in a substantially vertical direction. The food product is delivered to a cutting device through an internal passage of at least one feed member above the cutting device. A force is applied to the food product traveling downward through the internal passage so as to push the food product against a first wall of the feed member. The apparatus is configured to improve product flow by configuring the passage of the feed member to have a cross-sectional shape defined by two offset, overlapping diameters. The apparatus is also configured for improved safety by ensuring that the cutting device is properly secured before electrical power is available for driving the cutting device.

  • Patent number: 6634268
    Abstract: A method for cutting sections from a specimen using a microtome wherein a cutting knife or specimen is advanced by an advancing carriage into a sectioning plane of a disk microtome. The advancing carriage is moved by a motor drive in order to bring the specimen into contact with an area sensor. When the specimen comes into contact with the area sensor, the position of the motor drive is determined and is compared with a stored position of the sectioning plane. The stored position is previously determined by manually locating the position drive motor when the specimen contacts the area sensor. Control signals for the motor drive are calculated from the two position values, and the advancing carriage is advanced into the sectioning plane by the motor drive taking these control signals into account.

  • Patent number: 6272958
    Abstract: An apparatus for decurling food material, such as slices severed from a food material supply, while the slices are being moved toward a transfer member includes a constriction positioned in close proximity to the slicing station and in general alignment therewith. The constriction is defined by opposing upper and lower surfaces; the upper surface is a stationary surface while the lower surface is a moving surface. The lower moving surface utilizes a plurality of flexible bands rotating around at least one roller, which are disposed proximate to the food material supply. The flexible bands are driven around a guide member having an arcuate profile that matches the curvature movement that the food material supply takes. The bands which form the lower moving surface are driven at a speed equal to or greater than the speed at which the slicer operates.

  • Publication number: 20010003938
    Abstract: The invention relates to a knife holder for a microtome. The knife holder has a plate arranged pivotably on its base member and arranged, in its functional position covering the cutting edge of the knife, spaced apart from the cutting plane to the side of the knife holder remote from the specimen side, and at the same time spaced apart from the knife holder on the side of the cutting edge of the knife. By this arrangement of the plate, any gripping of the cutting edge of the knife can be precluded in the functional position of this plate. In advantageous embodiment examples of the invention, the pivoting mechanism for the plate is coupled to a switch which has the effect that, when the plate is pivoted out of the functional position, the motor drive of the cutting movement is locked, or that a brake precludes any movement of the knife slide or specimen slide.
