A fiber bundle winding device includes: a traverse guide configured to guide a fiber bundle to a bobbin; and a controller configured to control the traverse guide according to a rotation of the bobbin. The traverse guide is movable parallel to a center axis of the bobbin. The controller can perform: first movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a predetermined first area extending in a direction of the center axis of the bobbin; and second movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a second area being smaller than the first area and having ends that are located within the first area and at different positions from respective ends of the first area. The first movement control and second movement control are performed at a ratio of N:1 (N is an integer more than 1).
This slide rail unit is equipped with a long first rail which has a first facing surface extending in the lengthwise direction of the first rail, a long second rail which extends along the first rail and has a second facing surface which faces the first facing surface, and a rolling element which is positioned between the first and second facing surfaces. The second rail is assembled so as to be capable of moving relative to the first rail, and a reinforcing part formed from a fiber-reinforced resin material demarcates the first and/or second facing surfaces.
A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.
