ABSTRACT:
An apparatus and method for inserting optical fibers into a spacer having spiral grooves to produce a spacer type optical fiber cable wherein a torsional force detecting device is formed integrally with the optical fiber gathering device for inserting optical fibers into the spiral grooves. The torsional force exerted on the device by the spacer is detected by a tension/compression measuring device and the axial speed of the spacer is controlled in response to the measured torsional force so as to reduce the torsional force to zero.
