Abstract: A saw has a system for sensing the torque on a cutting blade to signal when the blade begins to cut material. The saw has a drive belt extending between a driven wheel and a drive wheel and a belt tensioner that engages a side of the belt and maintains tension in the belt. The belt tensioner is movable to maintain the tension in the belt. A control system calculates the movement of the belt tensioner. The saw has a system for determining the size of the sacrificial blade. A through beam photoelectric emitter and receiver pair are positioned on opposite sides of the blade such that a largest cutting blade is moved above the beam regardless of a horizontal position of the cutting blade and sensor senses a vertical position of the axis of the blade. The sensor senses the vertical position of the blade axis when the blade is moved above the beam.

Abstract: A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.

Abstract: The present invention relates to an apparatus and method for shaving the inside of barrels. In particular, the present invention relates to reconditioning used wine barrels by shaving the inside surface to a predetermined depth, ready for re-crozering, toasting, and re-use. Conventional shaving methods typically involve routing the internal surface by hand, but this technique is problematic in that it is a very slow process, the quality of the wood is often adversely affected, and there is no way of ensuring that the surface will be shaved to the same depth across the entire surface. Therefore, the resultant internal dimensions of the barrel are not reflective, relatively, of the original barrel surface. The apparatus of the present invention includes a scanning means adapted to scan the internal dimensions of the barrel, and a cutting means adapted to shave the internal surface to a predetermined depth relative to the scanned internal dimensions.

At the same time, a motion detector arrangement preferably comprised of one or more microelectromechanical (MEMS) accelerometer devices generates signals corresponding to motion of the position indicator support member as it is moved along the item. These signals are processed in a signal processor to determine the volume of the uncut selected segment of the item lying between selected successive positions of the indication member.

On the other hand, upon a later tear in the paper web, the base unit compares the shade of color of the dryer felt at the existing tear and the previously stored shade of color. If they match, the base unit activates the cutting-off device when (and only when) the stored shade of color of the dryer felt is recognized.

Abstract: A sorting system is disclosed for reclaiming lean meat from highfat meat trimmings. The sorting system includes a meat dicing machine which receives laterally extending whole meat trimmings and which dices such meat trimmings without grinding or extruding, and without disturbing the lateral distribution of the meat. This results in a lateral distribution of meat trimmings, without requiring vibratory distribution which is disfavored in meat processing plants. A wide-belt inspection conveyor is positioned at the downstream end of the meat dicing machine to receive the laterally distributed meat dices. The wide-belt inspection conveyor operates at a greater linear speed than does the meat dicing machine to longitudinally space the meat dices from each other. An optical inspection and sorting station is positioned at the downstream end of the wide-belt inspection conveyor to differentiate relatively lean meat dices from relatively fatty meat dices and to separate such meat dices from each other.
