A conversion unit converting a first continuous web substrate into a second substrate in the form of converted blanks of predetermined length. On account of cutting tool rotation speed, the web moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement for producing a first run driving of the web, a sheeter having rotary tools for cutting the web into blanks, a second motorized arrangement for producing a second run driving of the substrate, the second arrangement being positioned in the immediate proximity of the sheeter, and at least one station having rotary tools for converting the blanks. A speed of rotation of the second arrangement varies during a cycle of rotation of the tools of the sheeter, comprising a phase at constant tangential speed, substantially equal to the speed of rotation of the tools of the sheeter, during which the cut is made, a speed reduction phase, during which a length of the web, dependent on the difference between the length of the blank and an extension of the periphery of the tools, is kept upstream of the second arrangement, and a speed increase phase, during which the substrate is discharged downstream of the second arrangement.

A slotter head, a slotter apparatus, and a box making machine form a joining piece with a high degree of accuracy by each being provided with: a cutter rest; a movable block mounted in an outer peripheral portion of the cutter rest; a first cutting blade that is fixed to the movable block along a shaft direction and along a direction inclined in a circumferential direction by a predetermined angle; a first support shaft that supports, on the cutter rest, the movable block rotatably around a first shaft center along the shaft direction; and a second support shaft that supports, on the cutter rest, the movable block rotatably around a second shaft center along the circumferential direction.

The present invention relates to an apparatus and a process for cutting a substrate wherein the apparatus comprises first and second cutting element and wherein the first and second cutting elements are rotatable about the axis of rotation at different circumferential speeds.

A cutting device is configured to cut, in an arc shape, an end of a sheet conveyed in a conveyance direction. The cutting device includes an arc-shaped cutting blade; a switching mechanism; and a contact-and-separation mechanism. The switching mechanism is configured to switch a posture of the cutting blade in accordance with a position of the sheet facing the cutting blade. The contact-and-separation mechanism is configured to bring the cutting blade into contact with the sheet in a contact direction orthogonal to a surface of the sheet and away from the sheet in a separation direction opposite the contact direction, to cut the end of the sheet in the arc shape.

A food processor includes a bowl with a removable lid. Food items are advanced into the bowl through a feed tube formed in the lid where they are cut by a blade assembly. A rotating disk is adjustable relative to the blade assembly to vary the thickness of the food items cut by the blade assembly.

A cutting tool mechanism comprises a base, a fixing module disposed on the base for fixing a product to be disassembled, a first moving mechanism disposed on a side of the fixing module, and a three-dimensional cutter rotatably disposed on the first moving mechanism and matched with the fixing module. The first moving mechanism extends in a first direction and is configured to drive the three-dimensional cutter to move in the first direction, and the three-dimensional cutter is configured to be driven to move in a second direction and in a third direction, each of the second direction and the third direction being perpendicular to the first direction.

An adjusting device 1 of a cutting device has a mounting element 3 which is provided with a first through bore 7 through which a first shaft 9 projects. This first shaft 9 is provided at one end 9a with a rotary adjusting knob 13 and is provided with a second bore 15 which extends over the entire length of the first shaft 9 and is provided with internal screw thread over its entire length. The adjusting device 1 furthermore has an elongate coupling element 19 which can be connected to a device part to be adjusted. This coupling element 19 is provided with a second shaft 21 with an external screw thread, which is turned into the first shaft 9. When the adjusting knob 13 is turned, the second shaft 21 is displaced in the longitudinal direction. The second shaft can be rotated into the second bore 15 at both ends of the first shaft and can protrude from the first shaft at both ends.

A knife assembly for cutting a substrate during relative motion between the knife and the substrate, the assembly including a knife having a distal knife blade and a proximal knife shaft attached to a holder rotatable about a first axis perpendicular to the substrate to define a cut direction angle. The holder is also configured to rotate the knife blade about a second axis perpendicular to the first axis to form a notch angle relative to the first axis. The notch angle is preferably automatically infinitely adjustable within a range of angles. The holder may also, optionally, be configured to rotate the knife blade about a third axis perpendicular to a plane defined by the knife blade to adjust an angle of attack of the knife blade relative to the substrate.

A sheet processing system conveys a material sheet in a first direction; calculates an inclination angle of the first registration mark of the material sheet with respect to the first direction; and includes cutting blades configured to cut the material sheet to produce sheet pieces and a cutting direction adjustment mechanism configured to adjust a cutting direction to a direction of the inclination angle. The sheet processing system conveys the sheet piece in a second direction; and includes a guide member configured to extend in the second direction and to guide a cutting end of the sheet piece, a processing place position identification section configured to identify a position on a conveyance path of a processing place of the sheet piece based on the inclination angle, and processing mechanisms configured to perform processing on the processing place whose the position on a conveyance path is identified.

A method of determining a cutter height on a wedge bonding machine is provided. The method includes the steps of: (a) lowering a wedge bonding tool toward a surface on the wedge bonding machine; (b) determining a first height measurement when the wedge bonding tool contacts the surface; (c) lowering a cutter of the wedge bonding machine, relative to the wedge bonding tool; (d) determining a second height measurement when the cutter contacts the surface; and (e) determining a cutter height using the first height measurement and the second height measurement.
