A filament winding apparatus for rotating in a predetermined direction a core material that is supported by a supporting portion, and for winding around the core material, an elongated material which has flexibility and which is impregnated with an unhardened synthetic resin material, the filament winding apparatus includes a plurality of feeding portions for feeding a plurality of elongated materials, and a plurality of guiding mechanisms which are positioned around the core material so as to correspond to the plurality of elongated materials that are drawn from the plurality of feeding portions, through which the corresponding elongated materials are passed, wherein at least one of the supporting portion and the plurality of guiding mechanisms are movable in a rotation axial direction, from a winding operation range in which the elongated materials can be guided by the guiding mechanisms to winding positions at which the elongated materials are wound around the core material, to an attachable/detachable position at which the plurality of guiding mechanisms is separated relatively from the core material and the supporting portion.

Filament winding apparatus

A casting machine having a mold closing and opening cylinder for moving a movable die plate with a movable die relative to a stationary die plate having a stationary die, and a mold clamping cylinder each having a cylinder housing and a piston which partially define a first and a second fluid chamber whose volumes increase when the movable die plate is moved toward and away from the stationary die plate, respectively, by the mold closing cylinder. The clamping cylinder is connected to a hydraulic circuit, which permits a fluid to flow between the first and second chambers through a connecting line when the movable and stationary die plates are moved relative to each other by the closing and opening cylinder. The hydraulic circuit is adapted to apply a fluid pressure to the first fluid chamber to clamp the movable and stationary dies together after the movable die is brought into abutting contact with the stationary die by the closing and opening cylinder.

Hydraulically operated casting machine for producing a formed product,

A broaching machine for broaching an outer surface of a rotor of a rotor assembly which includes a support shaft projecting from opposite end faces of the rotor for supporting the rotor rotatably about its axis. The machine includes a backing plate for backing the rotor assembly such that one of the end faces of the rotor is held in contact with backing plate. The circumferential position of the rotor assembly is established by a positioning pin which extends from the backing plate, and engages a hole formed in the rotor. The machine includes a first centering device which has a center engageable with one of opposite ends of the support shaft so as to hold and center the support shaft at the one end, and a second centering device having a V-block and a retainer block which are engageable with the other end of the support shaft so as to hold and center the support shaft at the other end. With the first and second centering devices, the rotor assembly is easily and accurately mounted on the machine, with the axis of rotation of the assembly aligned with a line of feed of a broach cutter.
