摘要

The wire coiler comprises a stretching unit and coiler station and prevents plastic deformation of the wire during drawing out and coiling down. The unit has a drive shaft (5,6) and a sprung roller (14) within a fork (16), with an associated guide rack (17) for this. The shafts have main wire grooves (24) more than half the wire thickness in depth, one groove for each roller (14). Two grooves can allow two wires to be drawn by one roller, so that there are pairs of grooves for each of the several sprung rollers. If the shafts are fitted with wear-reducing rings, these in their turn are grooved to suit the number of wires being stretched. The clamping force of the rollers onto the wire is controlled by rods (21) and each draw-out unit is preceded by guides to lead the wires (1) accurately into the unit. A downstream roller can lead the wire over to the coiler. The wires are thus guided into and through the stretching unit, where the roller clamping force reinforces the friction to keep the wire moving. This is suitable for high speed applications.
