Abstract

Abstract Web slitting apparatus, particularly for metal webs, is provided with a rotating lock mechanism for maintaining the proper working relationship between the slitter knives on a pair of parallel rotating arbors. The lock mechanism comprises a pair of parallel spaced disks on one of the arbors and a single disk on the other arbor, which disks interfit radially to interlock the arbors against relative axial movement.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 134 words
Web slitting apparatus of the character described comprising: a. a machine base, b. first rotatable arbor means having disk-shaped shearing blades mounted thereon, c. second rotatable arbor means having disk-shaped shearing blades mounted thereon, d. means on said base supporting said first arbor means for rotation and including means restricting one end of said first arbor means against axial movement with respect to said base, e. means on said base supporting said second arbor means for both rotationally and axial movement in parallel spaced relation with said first arbor means, said blades on said arbor means cooperating to slit a web traveling therebetween, and f. means forming a rotating lock connection between said arbor means establishing predetermined limits on the axial movement of said second arbor means with respect to said first arbor means.
Claim 2
Dependent Claim 134 words
Web slitting apparatus of the character described comprising: a. a machine base, b. first rotatable arbor means having disk-shaped shearing blades mounted thereon, c. second rotatable arbor means having disk-shaped shearing blades mounted thereon, d. means on said base supporting said first arbor means for rotation and including means restricting one end of said first arbor means against axial movement with respect to said base, e. means on said base supporting said second arbor means for both rotationally and axial movement in parallel spaced relation with said first arbor means, said blades on said arbor means cooperating to slit a web traveling therebetween, and f. means forming a rotating lock connection between said arbor means establishing predetermined limits on the axial movement of said second arbor means with respect to said first arbor means.
Claim 3
Dependent Claim 80 words
Web slitting apparatus as defined in claim 1 wherein said lock means comprises a pilot disk secured on one of said arbor means and a pair of disks secured on the other said arbor means in predetermined spaced relation with each other and predetermined aligned relation with said pilot disk to receive said pilot disk therebetween, the spacing between said pair of disks being predeterminedly slightly greater than said pilot disk and providing for radial overlapping thereof without engagement therebetween.
Claim 4
Dependent Claim 60 words
Web slitting apparatus as defined in claim 2 further comprising means for effecting relative movement of said arbor means to bring said disks into and out of overlapping relation and said blades into and out of shearing engagement, said disks being of greater diameter than said blades for radial overlapping thereof in advance of said blades coming into shearing engagement.
Claim 5
Dependent Claim 26 words
Web slitting apparatus as defined in claim 2 further comprising means on said base for effecting substantially continuous lubrication of the overlapping surfaces of said disks.
Claim 6
Dependent Claim 30 words
Web slitting apparatus as defined in claim 1 wherein each said arbor means comprises a shaft having a portion of portions intermediate its ends whereon said shearing blades are mounted.
Claim 7
Dependent Claim 79 words
Web slitting apparatus as defined in claim 1 wherein each said arbor means comprises a shaft supported on said base, and a sleeve having said shearing blades mounted thereon and in turn mounted on said shaft, and further comprising means restricting one end of at least said shaft of said first arbor means against axial movement relative to said base, and means restricting said sleeve of said first arbor means against axial movement relative to said supporting shaft therefor.
Claim 8
Dependent Claim 68 words
In a web slitting apparatus of the character described wherein said slitting apparatus comprises parallel, supported, rotating arbor means having disk-shaped shearing blades mounted thereon in cooperative axially and radially aligned shearing engagement, the improvement comprising means for directly interlocking said arbor means against relative axial movement, said interlocking means comprising relatively rotatable means on respective said arbor means providing for relative rotation of said cooperative shearing blades.
Claim 9
Dependent Claim 68 words
In a web slitting apparatus of the character described wherein said slitting apparatus comprises parallel, supported, rotating arbor means having disk-shaped shearing blades mounted thereon in cooperative axially and radially aligned shearing engagement, the improvement comprising means for directly interlocking said arbor means against relative axial movement, said interlocking means comprising relatively rotatable means on respective said arbor means providing for relative rotation of said cooperative shearing blades.
Claim 10
Dependent Claim 80 words
Web slitting apparatus as defined in claim 7 wherein said interlocking means comprises a pilot disk secured on one of said arbor means and a pair of disks secured on another of said arbor means in predetermined spaced relationship with each other and predetermined aligned relation with said pilot disk to receive said pilot disk therebetween, the spacing between said pair of disks being predeterminedly slightly greater than said pilot disk and providing for radial overlapping thereof without engagement therebetween.
