A self-propelled cutter has a gear assembly to provide both downward and forward force on a material to be cut. A gear assembly includes a drive input gear that engages with a transfer gear and propulsion gear engaged with the transfer gear by a lever arm. The drive gear and transfer gear are coupled and fixed to the cutter body but the propulsion gear rotates about the transfer gear via the lever arm. This gear assembly enables the propulsion gear to move as required to provide both downward and forward force on a material to be cut, such as a cast. A self-propelled cutter may have a drive input that is coupled with a drive input device, such as a crank or an electric motor. A cutter may have a first gear assembly on a first side of the cutter body and a second gear assembly on a second side.

A spatula edge trimming apparatus for re-edging a spatula includes a base housing with the front side having a spatula receptacle slot extending through to the cavity. The bottom side has a drop aperture extending through to the cavity. The spatula receptacle slot is configured to receive a spatula. A cutter is coupled to the base housing within the cavity and is configured to cut an edge of the spatula. A drive is coupled to the top side of the base housing and is in operational communication with the cutter. A plurality of controls is coupled to the base housing and is in operational communication with the drive. A power source is coupled to the housing. The power source is in operational communication with, and provides power to, each of the drive and the plurality of controls.

A method for separating blanks includes continuous conveying of a sheet metal strip in a transport direction to a laser cutting station, concurrent cutting of the sheet metal strip by at least one cutting laser, wherein a cut sheet metal strip is formed from successive sections of the same cutting geometry, transporting the cut sheet metal strip on a first conveyor belt in the transport direction, taking over the cut sheet metal strip from the first conveyor belt, transporting the cut sheet metal strip in the transport direction, separately ejecting the at least one residual blank of each section, transporting the at least one blank of each section into overlap with a second conveyor belt and ejecting the at least one blank from the suction conveyor, and transporting the blanks ejected one after the other from the suction conveyor horizontally in the transport direction to a collecting station.

A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.

A sheet processing system according to an embodiment includes a tray that supports a sheet on opposite sides of the sheet orthogonal to a conveyance direction of the sheet. The tray includes a first adjustable support and second adjustable support positioned opposite the first adjustable support in the direction orthogonal to the conveyance direction of the sheet. A skew sensor detects a skew angle of the sheet conveyed to the tray. A corner sensor detects positions of each corner on a front end in the downstream direction of the sheet conveyed to the tray. A controller controls movement of the first and second adjustable supports based on the detected skew angle and the detected positions of each corner on the front end of the sheet conveyed to the tray so that the sheet is conveyed to the tray without jamming.

The invention relates to a device for cutting a base web with a separating device as well as a corresponding method, where the separating device can cut a base web into individual bases which can be guided under a fresh product. The separating device comprises a knife device and a counter cutting device, each of which comprise at least two cutting edges. The knife device and/or the counter cutting devices can be moved to and fro in two directions.

A microtome includes a blade; and a knife holder. The blade has a cutting edge configured to section a specimen block. The knife holder includes a base, a pressure plate and a frame. The pressure plate is connected to the base, and the pressure plate is adjustable relative to the base to clamp the blade between base and the pressure plate. The frame includes at least one limb and a bridge extending from the at least one limb parallel to the cutting edge. The bridge is proximate the cutting edge, the bridge and the blade cooperatively define a first gap therebetween, and the bridge and the pressure plate cooperatively define a second gap therebetween.

A hole puncher is provided, including: a frame, including a base and a guide portion, the base including at least one punching hole, the guide portion including at least one guide hole corresponding to the at least one punching hole, there being a distance between the punching hole and the guide hole; an operating lever, provably connected to the frame; at least one punching rod, driven by the operating lever, being relatively movable within the at least one guide hole and movable to come within or out from the at least one punching hole, each punching rod including a first straight section, a second straight section and a tapered section which is tapered from the first straight section toward the second straight section.

Described herein is a method for forming a monolithic surface in a ceiling system, the method comprising overlapping a first facing sheet and a second facing sheet to create an overlap region, each of the first and second facing sheets having a first major surface opposite a second major surface and side surface extending between the first and second major surfaces, wherein the lower surface of the first facing sheet contacts the upper surface of the second facing sheet within the overlap region, and running a blade of a cutting tool along the overlap region such that the blade extends through the first and second facing sheets at a cutting angle that is oblique to the first major surface of the first facing sheet within the overlap region.

A portable printer according to the present invention includes: a main body part having a paper feeding port and a paper discharge port; a cover part coupled to the main body part to be opened and closed; a cutting part disposed to be adjacent to the paper discharge port and cutting paper discharged from the paper discharge port; and an operating part sliding in at least two directions by an external force so as to operate the cover part or the cutting part.
