Abstract

PURPOSE:To accomplish linear arrangement with high precision without any torsion or sagging deformation of a stranded reinforcement so as to easily cut the stranded reinforcement by the predetermined length precisely by extending a long guiding line, which has a V-shaped cross section and serves as a measuring line at the same time, on the front side of a pulling-out ring at cutting intervals via a center guide. CONSTITUTION:When stranded reinforcements 30 are pulled out and passed through rings 3a, 3b so as to be guided by a center guide 4, the stranded reinforcements 30 are led out while centered on a guiding and measuring line 5. If the stranded reinforcements 30 are pulled out further and their tip parts are brought into contact with a stopper member in a measuring stopper 10, the stranded reinforcements 30 are smoothly pulled out and guided without any torsion or sagging deformation to the groove bottom part of the V-shaped cross section of the guiding and measuring line 5, and along its center part, the stranded reinforcements are linearly arranged with high precision. A pushing member 19 is lowered, and the stranded reinforcements 30 are fixed in the left end part of the guiding and measuring line 5, and then, a rotary cutter 18 in a cutting cutter 15 is lowered so as to cut the stranded reinforcements 30, and subsequently, the cut stranded reinforcements 30 are arranged in order on a bundling base 20.
