In a sickle cutting system, it has been found that a significant reduction in average stubble length, which is calculated based on the distance crop is pushed forwardly without cutting occurring, can be obtained by a combination of the features where the length of the cutting edge of each knife blade from a transverse rearmost cutting line at which a cutting action occurs is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.2 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.

Cutting device for longitudinally cutting a film web, in particular a plastic film web, moved in a web plane in a transport direction into a plurality of film bands, wherein a first cutter bar provided with cutting blades is immersed with the cutting blades in a cutting position into the web plane. In order to replace the cutter bar, a second cutter bar provided with cutting blades may be immersed with its cutting blades into the web plane, wherein the first cutter bar may be moved from the cutting position into a transfer position outside of the web plane when the second cutter bar is immersed with its cutting blades into the web plane.

A device for cutting the profile of a tyre tread (B) in a profiled element made of a raw rubber mixture comprises a frame (1) supporting a cutting assembly (2) and travel means (3) which make it possible for said profiled element (B) to be cut to travel in front of said cutting assembly (2), said cutting assembly (2) comprising at least one cutter (4) for cutting a longitudinal groove (S) in the outer face of said profiled element (B) and means (5) for inducing vibration in said cutter (4) in a transverse direction perpendicular to the direction of travel (X-X) of said profiled element.

A pipe cutting machine, which includes a hole-type movable cutting die (6b), which is driven by a drive lever (7), by means of which circular movements with a continuously variable stroke (h) can be performed, an eccentrically shaped crank pin bearing (26) in an outer shaft (18), in which a crank pin (11), which is arranged eccentrically on a crank pin drive (23), is movably supported in relation to the outer shaft (18), the crank pin (11) being in operative connection with the drive lever (7).

A micromachining method, a die manufacturing method, and a micromachining apparatus performing accurate micromachining on a surface of a workpiece at high speed. A micromachining apparatus having a cutting tool and a vibration unit for vibrating the cutting tool in a first direction is used. The angle formed between an average cutting direction of the cutting tool and the first direction is set to fall within a range of 20 to 120. Recesses and protrusions are formed on a surface of a workpiece as a result of machining by the cutting tool which is vibrating in the first direction.

A heat chamfering apparatus. A support unit supports a glass panel. A heat chamfering unit heat-chamfers an edge of the glass panel by applying thermal shock thereto. The support unit includes a contact support portion supporting the glass panel while in contact with the glass panel and a base portion configured to support the contact support portion. The contact support portion is formed from a first material. The base portion is formed from a second material. The first material has a smaller change in temperature due to lower thermal conductivity and a smaller change in size at high temperature due to a smaller coefficient of thermal expansion while being more ductile due to lower hardness, compared to the second material. In a heat chamfering method, a glass panel is located on a support unit, and an edge of the glass panel is heat-chamfered by applying thermal shock thereto.

A heat chamfering apparatus includes a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel and a heater heating the heated body. The heated body includes a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel. The cross-sectional area of the contact region is smaller than the cross-sectional area of the contact region. A heat chamfering method includes peeling an edge of a glass panel by applying thermal shock to the edge of the glass panel by moving a heated body heated by a heater relatively with respect to the glass panel along and in contact with the edge of the glass panel.

A processing apparatus for a base material tab protruding from a cylindrical electrode assembly includes: a vertical plate arranged in a second direction perpendicular to a first direction, the first direction being a longitudinal direction of the electrode assembly; a rotatable plate that is a planar plate arranged parallel to the vertical plate and coupled to be rotatable relative to the vertical plate; and a plurality of blades coupled between the vertical plate and the rotatable plate. The blades together form a variable diameter central area defined by ends of the blades according to the relative rotation of the rotatable plate to process the base material tab of the electrode assembly.

A cutting assembly for cutting an extruded edible material includes an extrusion assembly having a food extrusion port that extrudes an edible material in an extrusion direction. A cutter frame having a cutting edge is positioned proximate the food extrusion port. The cutting edge moves through a cutting region proximate the extrusion port in a cutting motion. First and second servo motors are operably coupled to the cutter frame, wherein the first servo motor operates the cutting edge to define a first component of the cutting motion perpendicular to the extrusion direction. The second servo motor operates the cutting edge to define a second component of the cutting motion generally parallel with the extrusion direction. The first and second servo motors combine the first and second components to define a cutting path and a return path of the cutting edge through the cutting region.
