Abstract: A method for manufacturing hand tools, such as wrenches. The method generally includes the steps of providing a flat stock, cutting the flat stock into the desired two-dimension blank using a laser, and three-dimensionally machining the laser-cut 2D blank into the desired three-dimensional workpiece. The tool may undergo a heating treatment process and a surface treatment process. In the context of a wrench, the blank may be laser cut with a laser beam oriented to cut generally perpendicularly to the plane of the flat stock. After laser cutting, the handle and interface region between the handle and jaw(s) are machined to provide the desired three-dimensional shape. For example, the three-dimensional shape may be selected to provide a comfortable grip even when applying a high level of force. The wrench jaw may have an optimized geometry calculated so that there is no excess material or “over-designed” regions of the jaw. The wrench jaw has internal corners with optimized radii.

Abstract: A self-retracting knife includes a housing having a forward end defining a blade aperture, and a blade carrier supports a removable knife blade and is movable within the housing from a fully extended position with the blade projecting from the blade aperture and a fully retracted position by a tension spring. An anti-retraction latch member is supported by the housing and is movable with finger pressure to a position that stops the blade carrier from fully retracting so that the knife blade is partially extended through the blade aperture. In other embodiments, the blade carrier extends through a carrier aperture at the opposite end of the housing for extending the blade carrier, and an adjustable extension limiter also extends through the carrier aperture for limiting forward movement of the blade carrier and projection of the blade through the blade aperture.

A leaf from a separating material is provided between at least two foodstuff slices. The unrolling device providing the separating material for disposal of the leaf between the two foodstuff slices and injects the leaf into the cutting region. The unrolling device has a tape roll and a delay unit. disposed downstream of the tape roll. The delay unit is configured for delaying the movement of the separating material, which is unrolled from the unrolling device and is provided in a cutting region of a cutting machine.

Abstract: The present invention is directed to a hair cutting apparatus (600), such as a shaver, which is enabled to detect whether hair is currently being cut in a robust way. Such apparatus has a motor (102) for driving a cutting element. The motor current (106) is evaluated by filtering and amplifying it in such a way that a time derivative of the motor current (106) is processed and other parts of the motor current (106), such as noise and DC-5 parts, are eliminated. An evaluator determines whether the time derivative of the motor current is above a predefined threshold value.

Abstract: An edge-breaking can opener includes a first clamping handle and a second clamping handle. The first clamping handle and the second clamping handle are rotatably connected by using a rivet. A round angle is set between a tray gear and a helical gear, which reduces a cutting height. A protrusion portion on an original cutter wheel is creatively changed to an elastically adjustable support wheel that acts on a can with different edge heights. It is convenient to perform occlusion during cutting, and a cut can cover can be directly and safely taken out, thereby preventing a hand from coming into contact with the can cover. The cutter wheel can easily perform cutting by using acting force of spring plate, which is suitable for cans with a certain material thickness.

For example, the apparatus may include a robot that may controllably move the fiber gun relative to a supporting member and align the fiber gun such that the one or more fiber segments are controllably positioned on the supporting member. The apparatus may further include a controller that at least partially controls operation of the apparatus.

Abstract: A computer-assisted shingle sawing method for recovery optimization using a 0-1 defect relative to the clear line, comprising the steps of taking an image of a next slab to be cut from a wood block; defining from that image, a clear line there-across; and locations of defect on that slab relative to the clear line, determining edge lines of shingles recoverable from the slab according to optimal shingle grade recovery; sawing the next slab along these edge lines, and sawing the next slab from the wood block, thereby releasing an optimum recovery of shingles from the slab. In another aspect there is provided a method for shingle recovery optimization using an optimization by inversion strategy, wherein the inclination of a parting line for cutting the next slab from the wood block is determined for optimal shingle grade recovery. There is also provided an installation for carrying out these methods.
