Abstract:
A paper web feeder for a rotary press, comprising:a pair of support frames opposing to each other; a rotary shaft rotatably supported by said pair of support frames; support arms provided in plural and radial about said rotary shaft for supporting a paper web rotatably at each arm tip and configured to rotate integrally with said rotary shaft; rotary conduction means located at a displaceable angle associated with rotation of said rotary shaft for conducting to an electric device, said electric device displacing in angle associated with rotation of said rotary shaft; stationary conduction means secured on either of said pair of support frames and conductive to said rotary conduction means; and connection means for electrically connecting said rotary conduction means to said stationary conduction means, wherein said rotary shaft has axial ends, at least one of said axial ends protruded outside from said pair of support frames, said rotary shaft also having a hollow portion formed therein extending from a mid-portion between said pair of support frames to said portion protruded outside from said pair of support frames, said stationary conduction means and said connection means are provided outside said pair of support frames, and said rotary conduction means has a portion extended through said hollow portion to outside said pair of support frames and electrically connected to said connection means.
