Abstract
A calibration apparatus and method for making a grooved plastic spacer for a slotted core telecommunications cable. The method includes attaching a calibration apparatus having helically shaped calibration members to an extrusion die. The calibration members are inserted into respective grooves of the spacer so that, as the spacer exits from the die, the calibration members maintain the shape of the grooves until the spacer is sufficiently cooled.
