A method of making a fiber (100) that includes continuously receiving a round wire (10), forming the round wire into a fiber having to have a cross-sectional shape defining a truncated circle having an aspect ratio of between 1.53 and 1.88, and simultaneously pulling and twisting the fiber a threshold number of twists per inch while retaining the aspect ratio of the fiber.

The present invention relates to a device for producing reinforcement cages having multiple longitudinal rods around which a wire, being welded to the longitudinal rods, runs, in particular for concrete tubes, wherein the device comprises a longitudinal rod guidance arrangement having multiple guidance elements and multiple radial guidances. To enable varying the shape of the cross-section of the reinforcement cage, the radial guides each comprise a spindle arrangement having at least one spindle, and at least two guidance element drives are provided which are configured to move one of the guidance elements each independently along the associated radial guidance.

Embodiments of the disclosure provide a printable cementitious composition comprising a cement binder, an aggregate, at least one pozzolanic additive, an accelerator, water, and nanoclay.

A portable cutting line may include a frame and a lazy susan. The portable cutting line may also include a cutting line main table, the cutting line main table operatively connected to the lazy susan and one or more tubs, the tubs operatively connected to the cutting line main table. The lazy susan, the cutting line main table, and the one or more tubs may be positioned within the frame when in transport position.

The preset invention relates to an apparatus for coupling arranged-reinforcement bars that can more precisely supply wires and bind and cut reinforcement bars, using a linkage member that longitudinally moves with rotation of a main shaft, and can stably operate by stably moving a guider for guiding wires.
