Claims
- 1. In a slitter which includes a frame, first and second bearing housings carried by said frame, said first bearing housing pivotally connected to said frame and carrying two or more spaced pairs of arbors having first and second ends, each pair of arbors connected at its said first end to said first bearing housing, each pair of arbors being alignable with said second bearing housing upon pivotal movement of said first bearing housing, each arbor pair second end supported by said second bearing housing when aligned with the second bearing housing, and drive means for rotating at least one of the arbors of each pair of arbors when aligned with said second bearing housing, said second bearing housing including means for shifting the second bearing housing relative to said frame and first bearing housing between an operative position aligned with a selected pair of said arbors and a standby position spaced from said selected pair of arbors, the improvement wherein said drive means includes a drive shaft shiftably supported above said frame, said drive shaft fixedly connected to said second bearing housing for longitudinal movement in its entirety with said second bearing housing when the second bearing housing is shifted between said operative and standby positions, said drive shaft including means for engaging one of said aligned arbors when the second bearing housing is in its said operative position for effecting rotation of the aligned arbors.
- 2. The slitter of claim 1 wherein said drive means further includes a motor, said motor including gear means operatively connected to said drive shaft for effecting rotative movement of the drive shaft, said drive shaft slidably connected to said gear means whereby the drive shaft shifts relative to said motor and gear means when the drive shaft shifts along with said second bearing housing.
- 3. The slitter of claim 1, wherein said drive means includes a drive motor and means connecting said drive motor to said drive shaft for imparting rotation to the shaft, said drive shaft being shiftable relative to said drive motor connecting means when said second housing is shifted between its operative position and its standby position.
- 4. In a slitter which includes a frame, first and second bearing housings carried by said frame, said first bearing housing pivotally connected to said frame and carrying two or more spaced pairs of arbors having first and second ends, each pair of arbors connected at its said first end to said first bearing housing, each pair of arbors being alignable with said second bearing housing upon pivotal movement of said first bearing housing, each arbor pair second end supported by said second bearing housing when aligned with the second bearing housing, and drive means for rotating at least one of the arbors of each pair of arbors when aligned with said second bearing housing, said second bearing housing including means for shifting the second bearing housing relative to said frame and first bearing housing between an operative position aligned with a selected pair of said arbors and a standby position spaced from said selected pair of arbors, the improvement wherein said drive means includes a drive shaft shiftably supported above said frame, said drive shaft fixedly connected to said second bearing housing wherein the drive shaft shifts along with said second bearing housing, said drive shaft including means for engaging one of said aligned arbors when the second bearing housing is in its said operative position for effecting rotation of the aligned arbors, said second bearing housing including a first sleeve and a second sleeve operatively connected to said first sleeve, said sleeves constituting means for rotatably carrying each pair of arbors, said drive shaft fixedly connected to said first sleeve.
