Abstract: A reinforcing fiber mat manufacturing apparatus according to the present invention is a reinforcing fiber mat manufacturing apparatus that includes a hitting mechanism (40) that comes into contact with a reinforcing fiber bundle to split the reinforcing fiber bundle into a plurality of pieces, and, disperses the plurality of pieces. The hitting mechanism (40) includes a rotation shaft (41), a pair of rotation plates (42) attached to portions of the rotation shaft (41) apart from each other, and a plurality of hitting pieces (43) arranged to extend in parallel to the rotation shaft (41) between the pair of rotation plates (42). The reinforcing fiber mat manufacturing apparatus according to the present invention is a simple apparatus that reliably hits a reinforcing fiber bundle to split the fiber bundle into thin bundles, and disperses the thin bundles to a wide range without causing air turbulence to manufacture a reinforcing fiber mat having a uniform fiber basis weight.

Abstract: A partially separated fiber bundle includes separation-processed sections, each divided into a plurality of bundles of at least three bundles, and not-separation-processed sections, that are alternately formed along the lengthwise direction of a fiber bundle that comprises a plurality of single fibers. The partially separated fiber bundle is characterized in that, at any width-direction cross-section taken along the lengthwise direction thereof, a rate of single fibers contained in a region at which adjacent divided fiber bundles are joined by a not-separation-processed part is 67% or less relative to the total single fibers in the width-direction cross-section.

Abstract: A gate valve is configured to have a first fluid flow path. In a state where a gate valve pin is at a first pin position, a front end section on an injection hole side of the gate valve pin closes an injection hole. In a state where the gate valve pin is at a second pin position that is more distant from the injection hole than the first pin position, a front end section opens the injection hole to make communication between the first fluid flow path and the injection hole and thereby form a resin supply line. In a state where a sleeve is at a first sleeve position and the gate valve pin is at the first pin position, a second fluid flow path is formed in the gate valve to connect an injection hole-side end of the first fluid flow path to outside of the gate valve and is made to communicate with the first fluid flow path and thereby form a cleaning line.
