A chopper assembly for cutting filaments in a strand into short lengths, comprising two rolls (1,4) being rotatable in opposite directions and having a pinch where the rolls (1,4) contact each other. At least one of the rolls (1,4) is provided with cutting blades (2,5) at its cylindrical outer surface. Means (15) are present for guiding said strand to said pinch where the filaments of the strand are cut. Both axes of rotation (16,17) of the rolls (1,4) are parallel to the tangential plane through said pinch and make an angle (α) with each other, so that the cutting blades (2,5) move in axial direction with respect to each other in the pinch.

The present invention relates to a device for separating medication packages from a strip of medication packages. The device comprises a cutting base along which the strip of medication packages is to be moved, a circular cutting blade arranged perpendicularly against the cutting base, and an actuator connected to the circular cutting blade and configured to move the circular cutting blade in opposite first and second directions for cutting the strip between two successive medication packages. In the device the actuator is connected to the circular cutting blade with a spring suspension allowing the circular cutting blade to move in opposite third and fourth directions perpendicular to the cutting base.

A tool including a tool surface and further including coding indicia linked, at least indirectly, with the surface of the tool, the coding indicia capable of being detected by a sensor, the coding indicia functioning as a pointer to information relating to said tool or its use.

A processing apparatus includes a cutting blade mounted on a spindle, the cutting blade having a cutting edge for cutting a workpiece held on a holding table, a measuring portion for measuring an edge projection amount of the cutting edge at a predetermined frequency, and a data processing portion. The data processing portion includes a lower limit recording portion for recording a lower limit of the edge projection amount of the cutting edge as an allowable limit for use of the cutting blade, a storing portion for storing blade information including the edge projection amount measured by the measuring portion and a cutting distance traveled by the cutting blade at the time of measurement of the edge projection amount.

The present invention is a cast iron pipe cutter. The cast iron pipe cutter includes a movable upper cutting tool and a rigid lower cutting tool. The upper cutting tool and lower cutting tool includes multiple cutting disc spaced an arc length apart. As the upper cutting tool is advanced downward by a hydraulic press, the cutting discs apply increasing pressure to the outer surface of a cast iron pipe until each cutting discs in the upper cutting tool and the lower cutting tool creates a fracture in the cast iron pipe. The multiple fractures created by the cutting discs amalgamate into a single fracture and the cast iron pipe is cut almost instantaneously.

A telescopic compression device (10) for flat bed die-cutting, stripping and part separating machines is provided, comprising a socket (12), at least one guide element (14, 15) which is slidably guided in the socket (12) and an elastic bias means (34) which biases the at least one guide element (14, 15) towards a furthest extended position and an elastic security element (44) which has an inherent stiffness and secures the at least one guide element (14, 15) to the socket (12). Furthermore, an exchange tool (2) of flat bed die-cutting machines, flat bed stripping machines or part separating machines is provided.

A processing apparatus 1 includes: a workpiece-set-position recognition unit 114 that moves an arm distal-end portion to a specified position measurement point to measure a shape of a workpiece in a workpiece set state in which the workpiece is positioned by a workpiece positioning unit, and thereby recognizes a set position of the workpiece; a processing-point-information generation unit 115 that, based on the set position of the workpiece and processing-target-portion information 124 indicating a position of a target portion of the workpiece for specified processing, generates processing-point information 125 indicating a processing point which is a movement point of the arm distal-end portion to perform the specified processing on the workpiece using a processing tool in the workpiece set state; and a workpiece-processing control unit 116 that moves the arm distal-end portion to the processing point based on the processing-point information 125 to perform the specified processing on the workpiece using the processing tool.

The invention provides a novel hard tissue slicing knife, comprising a knife back portion and a knife edge portion which are manufactured as a single piece; wherein the knife back portion has a cross section of an isosceles trapezoid, the knife edge portion has a cross section of an isosceles triangle; an end of the knife back portion which is away from the knife edge portion, has a thickness in a range of 4 mm to 15 mm; a junction between the knife back portion and the knife edge portion has a thickness in a range of 0.1 mm to 0.8 mm; the knife hack portion has a vertical height in a range of 27 mm to 38 mm; two faces of the knife edge portion is at an angle in a range of 10 degrees to 40 degrees.

The grinding unit includes at least one grinding wheel adapted to rotate around a respective rotation axis, and a thrust actuator adapted to push the grinding wheel against a cutting edge of a disc-shaped cutting blade. A load cell is also provided for detecting an axial thrust exerted on the grinding wheel.

A thermal printer configured to perform printing on a linerless label including an adhesive surface formed on a back surface of the linerless label, the thermal printer comprising a cutter unit that includes: a fixed blade provided on the back surface side of the linerless label; and a movable blade configured to reciprocate between a first position at which the movable blade is opposed to the fixed blade through intermediation of the linerless label, and a second position at which at least a part of the movable blade overlaps the fixed blade and the movable blade forms a cut in the linerless label, wherein the movable blade includes: a first blade edge configured to form the cut in the linerless label; and a groove, which has an edge, and is formed in a sliding surface configured to slide on the fixed blade when the movable blade is at the second position, and wherein the edge includes: an adhesive blocking edge portion formed on the sliding surface along an advancing direction; and an adhesive scraping edge portion formed on the sliding surface so as to cross the advancing direction.
