Abstract

An accumulator roll and a dispensing system for a cutting tape into a cross web track of an apparatus for cutting a moving web of paper includes first and second driving rolls for moving the tape into an entryway of a container and having a cutting station between them to cut a pre-determined single length of a cutting tape, the container includes a hollow formed by a circumferential surface in which the entryway is located and having a lateral slot therein located spacedly from the entryway, the hollow is formed by a plate extending laterally of the circumferential surface and having an arcuate slot generally medially of the plate, a press roll extending through the lateral slot beyond the circumferential surface, an accumulator roll having a rotating first shaft extending through the arcuate slot with accumulator roll being within the hollow and located adjacent to and urged toward the press roll for receiving the tape therebetween and wrapping the tape around accumulator roll, which is rotating at a speed higher than the linear speed of the tape entering the entryway, the accumulator roll is increased in diameter by the tape wound therearound causing first shaft to move within arcuate slot, the second driving roll maintaining a cut end portion of the tape therebetween with substantially its remainder wound on accumulator roll, the second driving roll pulling a free end of tape wound around the accumulator roll out of the entryway into the cross web track of the apparatus for cutting a moving web, and applying an adhesive strip to the tape thereof

In a system for dispensing a pre-determined single length of a cutting tape into a cross web track of an apparatus for cutting a moving web, said system comprising a first driving roll and a first cooperating press roll selectively movable toward and away from said first roll by an actuator, said first roll and first press roll sandwiching a cutting tape therebetween when said first press roll is moved toward said first roll and moving a cutting tape through a cutting station, a second driving roll and a second cooperating press roll selectively movable toward and away from said second roll by an actuator, said second driving roll being operatively coupled to said first driving roll, said second press roll receiving a cutting tape after passage through said cutting station with a cutting tape being sandwiched between said second roll and said second press roll for moving a cutting tape in one direction into an entryway of a container, said container including a hollow therein formed by a circumferential surface in which said entryway is located, said circumferential surface having a lateral slot therein located spacedly from said entryway, said hollow being formed by a plate extending laterally of said circumferential surface, said plate having an arcuate slot extending at its inner end generally medially of said plate to its outer end adjacent said lateral slot, a rotatable press roll having a fixed axis of rotation with its outer surface extending partially through said lateral slot beyond said circumferential surface of said hollow, an accumulator roll having a rotating first shaft extending through said arcuate slot with said accumulator roll being within said hollow and being located adjacent to and urged toward said rotatable press roll for receiving a cutting tape therebetween and wrapping a cutting tape around said accumulator roll, said accumulator roll rotating at a speed higher than the linear speed of a cutting tape entering said entryway, said accumulator roll being increased in diameter by a cutting tape wound therearound causing said first shaft to move from said outer end of said arcuate slot toward said inner end, said second driving roll and said press roll maintaining a cut end portion of a cutting tape therebetween with substantially its remainder wound on said accumulator roll, said second driving roll moving a cutting tape in another direction opposite to said one direction to pull a cutting tape from around said accumulator roll in a clockwise direction out of said entryway.
