A machining apparatus includes encoders that detect first rotational positions of motors that respectively drive an unwind shaft and a take-up shaft for conveying a material, an encoder that detects a second rotational position of a motor that drives a cutter edge for cutting the material, and a controller that controls the motor based on the first rotational position and controls the motor based on the second rotational position to coordinately control conveyance of the material and movement of the cutter edge. The controller calculates positional relationship information representing a positional relationship between the material and the cutter edge based on the second rotational position, determines whether the cutter edge is in contact with the material based on the positional relationship information, and estimates a life of the cutter edge based on a load on the motor when the tool is in a contact state.

An edge portion of a bound material is provided with first and second lines. The first and second lines are spaced at a small interval and arranged in parallel to each other. The first line is arranged outside of the second line of the bound material. A control unit controls first and second drive mechanisms in such a manner that the edge portion of the bound material is cut at the first line by a trim cutter, then the trim cutter or the table is moved at the small interval in a moving direction toward the second line, and then the edge portion of the bound material is cut at the second line by the trim cutter.

A cutting apparatus for cutting a web within a frame includes a die cutter assembly including a cutting blade projecting from a cylindrical surface and a counter anvil including first and second ends journaled into the frame. The counter anvil is positioned below the die cutter assembly for receiving the web fed therebetween across a width of the frame. The cutting apparatus includes first and second outboard bearing assemblies positioned on the die cutter near the first and second opposing ends, respectively, and one or more inboard bearing assemblies positioned about the die cutter assembly and spaced inwardly from the outboard bearing assemblies. Each outboard bearing assembly is configured to control a spacing between the die cutter assembly and the counter anvil along the width of the frame. The cutting apparatus also includes one or more actuators positioned atop the frame in connection with the one or more inboard bearing.

A machine for cutting a moving object comprises a conveyor belt for carrying the object along an advancement direction at a line speed and comprises a driving and cutting unit configured to move in a cutting cycle according to a forward phase in order to perform the cutting of the moving object, and configured to move according to a return phase in order to return into the initial position of the cutting cycle. The cutting machine further comprises a processing unit configured to generate a driving signal for controlling the movement of the driving and cutting unit with an acceleration trend wherein the maximum absolute value of the acceleration within the return phase is smaller than the maximum absolute value of the acceleration within the forward phase.

A rotary knife fixture for cutting vegetable products into spiral shapes. The knife fixture includes a blade holder driven rotatably within a hydraulic product flow path. The blade holder includes at least one cutting blade, wherein the blade is twisted with a sharpened leading edge set at a desired pitch angle. By controlling the pitch angle of the blade in relation to the blade rotational speed and velocity at which the potato travels along the hydraulic flow path, the resultant spiral cut shape is selected. By using multiple cutting blades at known axially spaced positions and selecting the angular position of each cutting blade in succession, the number of spiral shapes cut from each potato is selected. The blades can have a nontextured straight-cut edge, or a textured crinkle-cut edge, or a combination.
