Disclosed are apparatus, systems and methods of lubricating a knife which provides intermittently spaced cuts to a moving web, also referred to as perforations. In this manner, the apparatus, systems and methods are useful in both perforating a web and lubricating the knife used to form the perforations. the apparatus, systems and methods disclosed herein improve knife life, perforation quality and web handling.

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.

An orbital knife including a support structure; a yoke rotatably attached to the support structure constituting a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls securely connected to at least one of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls and including a cutting element; one or more sun gears rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; and one or more planet gears wherein each knife roll has rotatably attached thereto at least one planet gear and each planet gear is mated with a sun gear.

An orbital knife including a support structure; a yoke rotatably attached to the support structure having a yoke hub and a plurality of yoke arms; one or more rotatable knife rolls connected to at least two of the plurality of yoke arms; one or more blades attached to each of the one or more knife rolls; one or more sun gears rotatably attached to the support structure; an anvil roll rotatably attached to the support structure; one or more idler gears wherein each such idler gear is mated with one of the one or more sun gears; and one or more planet gears wherein each knife roll has rotatably attached thereto at least one planet gear and each planet gear is mated with one of the one or more idler gears, with the sun gear driving the idler gear which in turn drives the planet gear.

A cutting apparatus for cutting a food object includes at least one cutting blade, an actuator arranged for moving the cutting blade before and during cutting, and an element comprising a receiving section arranged for receiving and abutting the cutting blade, and a supporting section arranged for supporting a food object before and during cutting. During cutting, the supporting section is arranged for being displaced, such as displaced by elastic deformation, by the cutting blade with respect to a position of the supporting section prior to cutting. During moving of the cutting blade, the cutting blade is arranged for displacing the supporting section subsequent to the cutting blade abutting the receiving section. The cutting blade and the element are arranged for being continuously in contact with each other.

A device for manufacturing a chopped fiber bundle includes a cutter roll provided with one or more disk blades on a circumference of a roll core having a center axis coinciding with a rotation axis of the roll core and a nip roll provided in parallel with the rotation axis of the roll core, to feed a reinforcing fiber yarn to be continuously cut between the nip roll and the cutter roll, further including a rotary drive mechanism that rotates the cutter roll and at least one of: a reciprocating drive mechanism that reciprocates the cutter roll along the rotation axis of the roll core; and a traverse guide that traverses the reinforcing fiber yarn along the rotation axis of the roll core.

A cutter, such as a tubing cutter or a swing cutter. The cutter may include a cutting wheel; a roller; a housing assembly including a first housing portion supporting the cutting wheel and a second housing portion supporting the roller; a shaft connecting the housing portions, rotation of the shaft causing relative movement of the housing portions along a shaft axis; and a knob connected to the shaft and engageable by a user to rotate the shaft, the knob having, in a plane perpendicular to the shaft axis, a non-symmetrical shape defined by opposite circular sector portions and opposite lever portions, each lever portion being engageable by a user to apply a force to the knob in a direction of rotation. The cutter may include a shaft with a radial shoulder preventing movement of the shaft from the cavity through an opening in the housing portion.

A system for forming composite flake. An apparatus includes a first shearing assembly that meshes with a second shearing assembly to shear a length of composite material into a plurality of strips wherein reinforcing fibers of the composite material extend along the length of the composite strips. A chopping station receives the plurality of strips from the first and second shearing assemblies and shears the plurality strips across the axis of the reinforcing fibers to chop each strip into a plurality of pieces.
