A cable supply system includes a cable supply device supplying a cable, a cable buffer device storing a portion of the cable supplied from the cable supply device, and a control device controlling a cable storage amount of the cable buffer device. The control device controls the cable storage amount of the cable buffer device according to a cable supply speed of the cable supply device such that a cable output speed output from the cable buffer device is equal to a predetermined speed.

A filament winding apparatus includes a bobbin driving unit, a winding device, and a tension applying device. A filament winding method using the filament winding apparatus includes a temporary suspending step of temporarily suspending operation of the winding device in the middle of winding the fed-out fiber portion around the workpiece. In the temporary suspending step, the length of the feeding path is increased by moving the pressing member while causing the pressing member to press against the fed-out fiber portion in a state of continuing to feed out the fed-out fiber portion from the fiber roll portion.

A manual winding device comprises a wire bracket, a clamp, a winder, and a tension maintainer. The wire bracket supplies wire, while the clamp holds it in place. The winder, adjacent to the clamp, includes a driving mechanism and a coil former holding unit. The coil former holding unit is configured to mount a coil former. The driving mechanism is configured to drive the coil former holding unit to rotate, winding the wire onto the coil former. The tension maintainer, located between the clamp and the winder, includes a sliding base, a sliding block, and four connecting rods forming a quadrilateral. The sliding block is movably disposed on the sliding base. Two opposite connection points are pivotally mounted on the base and sliding block, while the other two points each hold a pulley around which the wire passes. The tension maintainer ensures the wire's tension is maintained during winding.
