Abstract
A system for forming and wrapping a plurality of stacks of sheet like product is provided. The system includes a separator apparatus for converting a stream of spaced apart sets of stacks into a repeating stepped configuration. The system includes a mechanism for merging the stepped configuration of stacks into a single file stream of stacks. The system includes a cutoff apparatus for cutting a plastic sleeve in which the stacks are wrapped. The system includes a turner apparatus for changing the direction of travel of individual units comprising of a stack of product within a length of the sleeve 90 degrees while maintaining the orientation of the units.
Claims18
A cutoff apparatus for cutting a plastic sleeve between adjacent spaced stacks of sheet like products positioned within the plastic sleeve, the plastic sleeve and spaced stacks of sheet like products moving longitudinally along a flow path, the cutoff apparatus comprising:
- a drive motor;
- a rotating arm operably coupled to the drive motor for rotation of the rotating arm about a rotational axis;
- and
- a first heated cutting element operably pivotally attached to the rotating arm such that the first heated cutting element is maintained at a substantially constant orientation as the rotating arm rotates about the rotational axis.
A cutoff apparatus for cutting a plastic sleeve between adjacent spaced stacks of sheet like products positioned within the plastic sleeve, the plastic sleeve and spaced stacks of sheet like products moving longitudinally along a flow path, the cutoff apparatus comprising:
- a drive motor;
- a rotating arm operably coupled to the drive motor for rotation of the rotating arm about a rotational axis;
- and
- a first heated cutting element attached to the rotating arm;
- a power supply operably attached to the heated cutting element to adjust a current flowing through the heated cutting element, the power supply configured to operably adjust the current flowing through the heated cutting element in relation to a rotational speed of the rotating arm about the rotational axis.
