The method is used to make metal fibers, more particularly steel fibers, from strip-shaped flat material, where the metal fibers have a substantially rectangular cross-section, and at least one of the wide side faces, preferably both of the wide side faces, is provided with at least one V-shaped anchor groove running longitudinally of the fiber. First, a material matched to the strength required for the metal fibers when they are used later on is used as the metal strip. In a first production line the metal strip, is fed from a coil to a straightening and transporting unit (3) by a driven and controlled unwinder (1). Downstream of a crop shear (4) that forms the leading end of the strip, the metal strip is fed to a profiling roll pair (6) consisting of an upper roll and a lower roll and forming a rolling tool. The profiling roll pair introduces anchor grooves and fracture grooves. Subsequently, the metal strip passes through a combined scoring and straightener (7) for scoring or straightening the anchor lines in the fracture grooves by means of one or more scoring roller pairs, and the metal strip is finally wound as a coil again by a winder (8). Thereafter, the last process step of the fiber make is carried out at a longitudinal and transverse dividing unit.

Provided are a method for manufacturing a Figure-T shaped metal part using a metal plate or a metal rod split by a method for splitting longitudinally an end part of the metal plate or the metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a Figure-T shaped metal part manufactured by such method. The method for splitting is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A handheld circular sawing device for severing armored cable includes a housing. A first plate is coupled to and extends coplanarly with a first side of the housing. A second plate is positioned substantially perpendicular to the first plate along a lower edge of the first plate. The second plate is hingedly coupled by a first end to the first plate proximate to a rear of the housing. A second end of the second plate is positioned proximate to a front of the housing to define a channel. A power module and a motor are coupled to the housing. The motor is operationally coupled to the power module. A blade that is coupled to a shaft of the motor protrudes into the channel. The motor is positioned to rotate the blade coincident with the shaft to longitudinally cut a section of a tubular substrate that is positioned in the channel.

A continuous processing system and method for the continuous processing of an electrical conductor cable having aluminum strands encasing a steel core directly from a puller or from a puller and reel, simultaneously or on-the-fly during substantially the entirety of a reconductoring or re-stringing of the cable, wherein such cables are used for power lines or for static wires. The system is adapted to cooperate with a pulling machine. The pulling machine may be formed integrally within the system or may be a conventional pulling machine which cooperates with the system. The processing system runs continuously, substantially without interruption, during the pull of all of the cable from the pull zone of the reconductoring or restringing.
