Abstract
The present invention provides a horizontal paper cutter that includes a pair of movable arms, each of which has a spindle attached thereto. The spindles are generally aligned with each other, and are configured to engage respective ends of a horizontally oriented paper roll. A pair of actuators are used to move the arms upward, thereby lifting the paper roll off the floor. One of the spindles is operable to rotate the paper roll after the paper roll is lifted off the floor. A saw that is initially above the paper roll is moved downward into the paper to effect removal of a damaged end of the roll.
Claims20
An apparatus for cutting a horizontally oriented paper roll, the apparatus comprising:
- a base including a movable arm;
- a spindle configured to cooperate with the arm and to engage an end of the horizontally oriented paper roll, the spindle being operable to rotate the paper roll about a longitudinal axis;
- an actuator cooperating with the arm for selectively adjusting the height of the spindle, the actuator being operable to lift the paper roll off a resting surface to position the paper roll for cutting when the spindle is engaged with the paper roll;
- a support proximate the base;
- and
- a blade supported by the support and movable in a plane generally perpendicular to the longitudinal axis, the blade being movable into the paper roll for cutting the paper roll.
A horizontal paper cutter, comprising:
- a base including a pair of movable arms, each of the arms having a spindle attached thereto, each of the spindles being generally aligned with the other spindle and configured to engage a respective end of a horizontally oriented paper roll, at least one of the spindles being operable to rotate the paper roll about a longitudinal axis;
- a pair of hydraulic cylinders, each of the cylinders cooperating with a respective arm for selectively adjusting the height of a respective spindle to a predetermined height, the cylinders being operable to lift the paper roll off a resting surface to position the paper roll for cutting when the spindles are engaged with the ends of the paper roll;
- a vertical support proximate the base;
- and
- a rotary saw supported by the vertical support and movable along a length of the vertical support, the saw being movable into the paper roll for cutting the paper roll.
A method of producing a horizontal paper cutter from a paper roll stand, the stand including a base and a pair of actuators, the base including a pair of movable arms, each of the actuators cooperating with a respective arm for selectively adjusting the height of at least a portion of the respective arm, the method comprising:
- attaching a spindle to each of the arms such that the spindles are in general alignment with each other, each of the spindles being configured to engage a respective end of a horizontally oriented paper roll;
- setting a maximum extension of the actuators to a predetermined fixed distance, thereby facilitating lifting of the paper roll to a predetermined fixed height for cutting;
- providing a vertical support proximate the base;
- supporting a blade on the vertical support such that the blade is movable along a length of the vertical support, thereby facilitating movement of the blade into a paper roll engaged by the spindles.
