Abstract: A slicer comprising a power base and a removable food support assembly. The food support assembly comprises a support base, a product tray, product tray slides, a bearing assembly, an adjustable plate, a gauge plate adjuster, and a blade. The power base comprises individual supports, a switch unit, a power cable, and a drive motor assembly having a blade drive coupling system. After setting the adjustable plate to the desired thickness using the gauge plate adjuster, the user switches the switch unit to the “on” position to initiate the drive motor assembly, which rotates the blade drive coupling system and, in turn, causes the blade to turn and slice the food product. Once the food product has been sliced, the removable food support assembly is removed from the power base and immersed in water or inserted into a dishwasher for faster, safer, more efficient, and more sanitary cleaning.

Abstract: A cutting arrangement for longitudinally cutting material includes two blades disposed across from one another and which cooperate during cutting. Each blade is embodied as a circular blade having a sharp cutting edge and supported by an adjusting or placement mechanism. During the cutting process, the circular blades are positioned by the adjusting or placement mechanisms so that the cutting edges overlap one another to form an overlap zone, the center of which coincides with the middle of the material that is to be cut. An adaptive control assembly includes individual drive motors for driving each blade and enables constant side load force control for each blade, such that side load pressures are adjustable in response to changes in web sped, web tension, and blade condition in real time. Automatic blade diameter sensors calculate the zero point of the cut, determine the appropriate blade speed and automatically set the overlap.

Abstract: A material cutting machine has a tool mount support mounted for reciprocal movement and a tool mount supported by the tool mount support. A driver, such as a pneumatic cylinder, selectively advances and retracts the tool mount support. A control system is operatively coupled to the driver for setting the advancement force of the tool mount support when a tool supported by said tool mount contacts a workpiece, such as the edge or surface of a moving strip. In this way, the depth of cut of the tool is controlled by tool advancement force rather than by accurate positioning of the tool. In one embodiment, the tool mount support may have a head and a base and a resilient member resiliently coupling the head to the base to provide a damped resilience. With this embodiment, a transient spike in the reaction force which may result, for example, from a hard spot in the material, causes the tool to momentarily deflect.

Abstract: Apparatus and methods for producing uniform pieces of meat or other product when cut or sawn from a non-uniform thickness lump. A band saw or the like is adjustable in position to produce different depths of cut piece under the control of signals produced by a control unit. The control employs a keypad for entering numerically the target weight for the cut pieces and an assumed density value for the product. A display unit displays the numerical values entered. A weighing device checks the weight of each cut piece (or batch multiple cut pieces) to produce the actual weight (or average weight) of the cut piece(s) and the control unit compares the actual or average value with the expected value of weight and adjusts the density value if required. The area of the end face of the product is measured by sampling the height of the end face of the product as it passes a sensor.
