Slitter having pivotal multiple spaced pairs of arbors

Claim 2

A slitter comprising a frame, first and second spaced housings carried by said frame, means pivotally connecting said first housing to said frame, said first housing carrying multiple spaced pairs of arbors, each pair of arbors connected at one end to said first housing, each arbor adapted to carry removable cutters, each pair or arbors being alignable with said second housing upon pivotal movement of said first housing, the other end of each pair of arbors being supported by said second housing when said arbors are aligned with said second housing, whereby said pairs of arbors so supported by said second bearing housing may be utilized for one slitting operation and simultaneously therewith another pair of arbors may be fitted with cutters for use in another subsequent slitting operation.

Claim 3

A slitter comprising a frame, first and second spaced bearing housings carried by said frame, means pivotally connecting said first bearing housing to said frame, said first bearing housing carrying multiple spaced pairs of arbors, each pair of arbors journaled at one end within said first bearing housing, each arbor adapted to carry removable cutters, said second bearing housing being shiftable toward and away from said first bearing housing, each pair of arbors being alignable with said second bearing housing upon pivotal movement of said first bearing housing, the other end of each pair of arbors being journaled within said second bearing housing when said arbors are aligned with the second bearing housing and said second bearing housing is shifted toward said first bearing housing, whereby said pairs of arboRs so journaled within said second bearing housing may be utilized for one slitting operation and simultaneously therewith another pair of arbors may be fitted with cutters for use in subsequent slitting operation.

Claim 4

A slitter comprising a frame, first and second spaced bearing housings carried by said frame, means pivotally connecting said first bearing housing to said frame, said first bearing housing carrying multiple spaced pairs of arbors, each pair of arbors journaled at one end within said first bearing housing, each arbor adapted to carry removable cutters, said second bearing housing being shiftable toward and away from said first bearing housing, each pair of arbors being alignable with said second bearing housing upon pivotal movement of said first bearing housing, the other end of each pair of arbors being journaled within said second bearing housing when said arbors are aligned with the second bearing housing and said second bearing housing is shifted toward said first bearing housing, whereby said pairs of arboRs so journaled within said second bearing housing may be utilized for one slitting operation and simultaneously therewith another pair of arbors may be fitted with cutters for use in subsequent slitting operation.

Claim 5

The slitter of claim 2 and drive means for rotating at least one of the arbors of each pair of arbors when journaled in said second bearing housing.

Claim 6

The slitter of claim 3 wherein said drive means includes parts carried by said second bearing housing making driving contact with said one arbor when journaled in said second bearing housing.

Claim 7

The slitter of claim 4 wherein said drive means includes a drive shaft carried by said frame, a sleeve journaled for rotation within said second bearing housing, means connecting said sleeve to said drive shaft for rotation with but permitting longitudinal movement relative to said drive shaft, means securing said sleeve to said second bearing housing for shiftable movement with said second bearing housing toward and away from said first bearing housing, said sleeve remaining in rotatable contact with said drive shaft during said shiftable movement of said second bearing housing, said one arbor being alignable with said sleeve upon pivotal movement of said first bearing housing and carrying means for connecting said one arbor to said sleeve for rotation with said drive shaft when said second bearing housing is shifted toward said first bearing housing.

Claim 8

The slitter of claim 5 and a second sleeve journaled for rotation within said second bearing housing, the other of the arbors of each pair of arbors being alignable with said second sleeve upon pivotal movement of said first bearing housing and carrying means for connecting said other arbor to said second sleeve, first gear means carried by said sleeves, second gear means in driving association with said first gear means for causing rotation of said second sleeve and connected other arbor upon rotation of said drive shaft.
