An apparatus for severing a workpiece having a cutting mechanism operable to cut the workpiece substantially along a selected course; drive mechanism operable to drive the cutting mechanism to cut the workpiece; a transport assembly operable to guide the workpiece in movement relative to a predetermined severing position and with respect to the cutting mechanism; and a frame mounting the cutting mechanism and transport assembly in predetermined relation to each other and relative to the severing position so that the drive mechanism is operable to drive the cutting mechanism to cut the workpiece in the severing position.

A cutting machine head and a cutting machine are provided in the present invention. The cutting machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. The cutter holder is mounted on the fixing plate. The machine head lifting mechanism is connected to the cutter holder, and is used to drive the cutter holder to move up and down on the fixing plate. The cutting component includes at least two cutter head assemblies mounted on the cutter holder. The machine head rotating mechanism is connected to the cutter head assemblies for driving the cutter head assemblies to rotate. The rotating angle of each cutter head assembly of the cutting machine head can be controlled. The machine head rotating mechanism controls the cutter head assembly to rotate when the machine head is cutting, and the resulting cutting line has no flaws, which can ensure the integrity of the cutting pattern.

A controller of a cutting apparatus specifies a target position of an attaching portion in a fifth direction and controls a second moving mechanism to move the attaching portion in a third direction. If the controller determines that the attaching portion has reached the target position, the controller executes cutting processing based on the obtained cutting data by controlling the second moving mechanism based on a pressure corresponding value achieved when the attaching portion is located at the target portion. If the controller determines that the pressure corresponding value has reached a pressure threshold, the controller executes the cutting processing by controlling the second moving mechanism based on the pressure corresponding value achieved when the attaching portion is located at a first particular position where the pressure corresponding value is equal to or lower than the pressure threshold value. The controller restarts controlling the second moving mechanism.

An absorbent article processing device includes a cutter roll and an anvil roll. The cutter roll includes a roll main body; a blade protruding in a radial direction in a first angular range of a part of a circumferential direction of the roll main body; a first bearer protruding in the radial direction in a second angular range of a part of the circumferential direction including at least the first angular range and being in contact with the anvil roll, and being cut out in an angular range excluding the second angular range at a first end portion in an axial direction of the roll main body; and a second bearer provided around the entire circumference or a part of the circumferential direction and being in contact with the anvil roll at the second end portion in an axial direction of the roll main body.

A conversion unit converting a first continuous web substrate (2) into a second substrate in the form of converted blanks of predetermined length (3). On account of cutting tool rotation speed, the web (2) 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 (4) for producing a first run driving (F) of the web (2), a sheeter (12) having rotary tools (13, 14) for cutting the web into blanks (3), a second motorized arrangement (17) for producing a second run driving of the substrate (2, 3), the second arrangement being positioned in the immediate proximity of the sheeter (12), and at least one station (21, 22, 23) having rotary tools (26, 27, 28, 29, 32, 33) for converting the blanks (3). A speed of rotation (38, 41) of the second arrangement (17) varies during a cycle of rotation of the tools (13, 14) of the sheeter (12), comprising a phase at constant tangential speed (46), substantially equal to the speed of rotation of the tools (13, 14) of the sheeter (12), during which the cut is made, a speed reduction phase (43), during which a length of the web (2), dependent on the difference between the length of the blank (3) and an extension of the periphery of the tools (26, 27, 28, 29, 32, 33), is kept upstream of the second arrangement (17), and a speed increase phase (44), during which the substrate (2, 3) is discharged downstream of the second arrangement (17).
