Abstract

Abstract A device for simultaneously manufacturing a plurality of fiber bundles for use in fiberscopes comprises a number of pairs of slit forming plates arranged along two longitudinal rows perpendicular to a disk reel to which are secured these pairs of slit forming plates with the aid of a base plate extending perpendicular to the disk reel. These pairs of slit forming plates are detachably mounted on two longitudinal shafts which are slidably and rotatably supported by the base plate, whereby a desired gap is defined between each pair of slit forming plates.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 290 words
A device for manufacturing a plurality of fiber bundles comprising a disk reel rotatably mounted on a rotary shaft; a base plate secured at its one end by a mounting plate to said disk reel and extending perpendicular to said disk reel and having at its each end an end plate; a number of parallel partition plates secured to said base plate and arranged between said end plates in two longitudinal rows and spaced apart one from the other, said two longitudinal rows being spaced apart from each other along the outer periphery of said disk reel; two longitudinal shafts slidably and rotatably supported by said end plates and extending through said parallel partition plates; a number of pairs of slit forming plates, each pair of slit forming plates being detachably mounted on each of said two longitudinal shafts; a spacer detachably sandwiched between said each pair of slit forming plates and having a thickness substantially larger than the diameter of a fiber to be wound; a resilient engaging member comprised of a collar integral with said longitudinal shaft and an elastic member fitted around said longitudinal shaft and in contact with one of each pair of said slit forming plates; a spring inserted between one of said shaft ends and said plate and urging said longitudinal shaft toward the other shaft end; and means for axially moving said shaft against the action of said spring and comprised of a nut secured to said end plate and a knob threadedly engaged with said nut, whereby said each pair of slit forming plates are urged against corresponding partition plates to form a slit with gap substantially larger than the diameter of one fiber and having wound therein fibers in superimposed relation.
Claim 2
Independent Claim 290 words
A device for manufacturing a plurality of fiber bundles comprising a disk reel rotatably mounted on a rotary shaft; a base plate secured at its one end by a mounting plate to said disk reel and extending perpendicular to said disk reel and having at its each end an end plate; a number of parallel partition plates secured to said base plate and arranged between said end plates in two longitudinal rows and spaced apart one from the other, said two longitudinal rows being spaced apart from each other along the outer periphery of said disk reel; two longitudinal shafts slidably and rotatably supported by said end plates and extending through said parallel partition plates; a number of pairs of slit forming plates, each pair of slit forming plates being detachably mounted on each of said two longitudinal shafts; a spacer detachably sandwiched between said each pair of slit forming plates and having a thickness substantially larger than the diameter of a fiber to be wound; a resilient engaging member comprised of a collar integral with said longitudinal shaft and an elastic member fitted around said longitudinal shaft and in contact with one of each pair of said slit forming plates; a spring inserted between one of said shaft ends and said plate and urging said longitudinal shaft toward the other shaft end; and means for axially moving said shaft against the action of said spring and comprised of a nut secured to said end plate and a knob threadedly engaged with said nut, whereby said each pair of slit forming plates are urged against corresponding partition plates to form a slit with gap substantially larger than the diameter of one fiber and having wound therein fibers in superimposed relation.
Claim 3
Dependent Claim 112 words
A device for manufacturing a plurality of fiber bundles as claimed in claim 1, wherein said longitudinal shaft has at each side flat portions and said each pair of slit forming plates have a hole slightly larger in diameter than said longitudinal shaft and a groove extending from said hole to the lower end of said each pair of slit forming plates and having a width substantially equal to the distance between said flat portions, whereby said each pair of slit forming plates are detachably mounted on said longitudinal shaft when in one of two rotary positions and are locked to said longitudinal shaft when rotated from said position by 90* .
Claim 4
Dependent Claim 58 words
A device for manufacturing a plurality of fiber bundles as claimed in claim 1 and comprising further an intermediate plate secured to one of said partition plates and aligned with the slit forming plate which is in contact with said partition plate and having a front surface projecting substantially beyond the front surface of said slit forming plate.
Claim 5
Dependent Claim 63 words
A device for manufacturing a plurality of fiber bundles as claimed in claim 1 and comprising further an anti-rotation member arranged between said knob and one end of said shaft and comprised of a ring engaged throgh a key-groove connection with the inside wall of said nut, whereby said knob together with said longitudinal shaft are axially movable along said nut and nonrotatable.
