A method for manufacturing a machine component includes forming a non-linear break notch in a workpiece, freezing the workpiece, and snapping the frozen workpiece apart along the non-linear break notch.

A process and an apparatus for making a refastenable side seam of an hygienic absorbent article efficiently, without the need to remove scrap and which allows refastenable side seams to be obtained which are ergonomic, aesthetically pleasing, easily identifiable by the user and such that they do not reduce the wearability of the article. The disclosure also relates to a hygienic absorbent article provided with at least one refastenable side seam. The disclosure also relates to a process and an apparatus for carrying out one or more operations on elastic panels usable for making an hygienic absorbent article provided with at least one refastenable side seam.

A fiber cutter includes: a base including a fiber grip that grips an optical fiber; a slider including a fiber end grip that grips an end portion of the optical fiber, wherein the slider moves relative to the base; a cut former including a blade forming an initial cut in the optical fiber and disposed between the fiber grip and the fiber end grip; and a spring that applies a force between the base and the slider to apply a tension to the optical fiber gripped by the fiber grip and the fiber end grip, wherein the cut former is disposed on the slide, and when the initial cut grows and the optical fiber cleaves, the cut former moves together with the slider by the force of the spring.

Embodiments of a ticket burster employ a dividing wall that is movable between different positions to facilitate dispensing tickets of different sizes, and a sensor that detects and communicates the position of the dividing wall to a controller. The controller communicates with feed motors to selectively operate feed drive rollers independently or in unison depending upon the detected position of the dividing wall.

A field-pole magnet manufacturing apparatus fractures a magnet fixed on a die serving as a lower tool by causing a punch of an upper tool to press the magnet while in contact with the magnet. At least one projection is formed in the punch of the upper tool symmetrically with respect to the central position of the magnet in the width direction of the magnet.

A cutting apparatus includes: a stage on which is disposed a preliminary stacked body from which a cut stacked body having an edge is formed; a cutting unit movable along a first direction corresponding to an extension direction of the edge of the cut stacked body and with which the preliminary stacked body is cut to form the cut stacked body; a first detaching unit movable in a direction forming an acute angle with the first direction and including a first detaching tool which contacts the cut stacked body in detaching of the cut stacked body from the carrier substrate; and a second detaching unit movable in a direction parallel to the first direction and including a second detaching tool which is inserted between the cut stacked body and the carrier substrate in the detaching of the cut stacked body from the carrier substrate.

Embodiments of the present invention relate to a system and method for manufacturing a three-dimensional object from a stack of pre-stripped layers of substrate. Each object layer is formed by (i) providing substrate comprising waste portion(s) and substrate-retained portion(s) that are attached to each other and separated from one another by cut(s) within the substrate; (ii) subsequently, subjecting the subject of each layer to a stripping process which selectively strips away substrate-waste portion(s) from the substrate-retained portion(s). After stripping, the object layer is added to a stack of previously-stacked object layers to grow the stack. This process is repeated to further grow the stack. Object layers of the stack are bonded to each other to build the three-dimensional object therefrom. Apparatus and methods for stripping are also describedany teaching or combination of teaching(s) related to stripping substrate may be employed in any additive-manufacturing process described herein.

A procedure is provided for evaluating the score, snap and edge appearance of wallboard panels, and includes scoring a wallboard panel with a knife at a constant and known force using a benchtop board scoring device; snapping the scored panel in a Universal Board Testing Machine to measure the breaking force, forming a snapped panel edge; measuring a cleanliness of the snapped panel edge by placing a straight edge against the snapped panel edge and measuring gaps between the snapped panel edge and the straight edge in a plurality of locations on a face of the panel, and a plurality of locations on a back of the panel; and averaging all of the measured gaps to create an Index Score.

A method for cleaving a fiber comprises rotating an actuator to apply a positioning force to a blade in a scoring assembly. The positioning force produces a score in the surface of a fiber, and the method further comprise applying a cleaving force to the fiber to cleave the fiber. The method can further include measuring the magnitude of the positioning force and rotating the actuator until the magnitude corresponds to a pre-determined magnitude. A cleaver comprises a scoring assembly, drive assembly, and a cleaving assembly. The scoring assembly includes a holder having one or more blades, and an actuator. The cleaving assembly secures a fiber in the scoring assembly. The drive assembly rotates the actuator to position one or more blades to score the surface of the fiber. The cleaving assembly applies a cleaving force to the fiber to cleave the fiber at the location of the score.

A method for laser preparation of a coated substrate to be laser cut is provided. The method includes substantially removing a target portion of a polymer coating from a coated substrate by directing an ablative laser beam to the target portion, wherein the target portion of the polymer coating has a width of between about 10 m and about 6.0 mm.
