Abstract: An interfolding apparatus including a frame, a first interfolding roll supported for rotation by the frame, a second interfolding roll, and a mass damper. The first interfolding roll is rotatable about a first axis, and the second interfolding roll is rotatable about a second axis and is disposed adjacent to the first interfolding roll to define a nip therebetween. The first and second interfolding rolls are rotatable to contact each other during rotation, and the contact between the first and second interfolding rolls creates vibration of at least the first interfolding roll. The mass damper is coupled to the frame and absorbs at least a portion of the vibration energy of the first interfolding roll to reduce vibration of the first interfolding roll.

Abstract: A method and apparatus for wrapping stacks of web product with wrap web material supplied from a supply roll. The apparatus includes a conveyor for supporting and moving the stacks to be wrapped along a conveying path, a drive assembly operable to receive wrap material from the supply roll and positively feed the wrap material to the conveying path, and a wrapping assembly for manipulating the wrap material around the stack. The method includes supporting and moving the stacks to be wrapped along a conveying path, rotating a cutting roll, clean cutting the wrap material received from the supply roll to separate a wrap sheet from the wrap material, defining a trailing edge of the wrap sheet, delivering the trailing edge to the conveying path after the wrap sheet is separated from the wrap material, and manipulating the wrap sheet around the stack.

Abstract: A starwheel feed apparatus and method for feeding and guiding sheets of a web material into a starwheel assembly. In some embodiments, a feeding conveyor is movable to convey sheets at a first velocity toward the starwheel, and a guiding conveyor is located adjacent the starwheel and has a conveying surface movable at a velocity less than the first velocity. In other embodiments, other relative speeds of the guiding and feeding conveyors are employed. In some embodiments, a feeding conveyor feeds sheets into slots of a starwheel, and a guiding conveyor located adjacent the starwheel has a conveying surface to guide trailing edges of the sheets along a length of the conveying surface as the sheets enter the slots.

Abstract: An apparatus and method for moving stacks of product discharged from a stacking device. The apparatus includes a first conveyor movable at a first speed and a second conveyor movable at a second speed. The first conveyor includes an upstream end adjacent to the stacking device. The first conveyor is positioned to receive product from the stacking device. The second conveyor includes an upstream end adjacent to the stacking device. The second conveyor is positioned to receive product from the stacking device. The running speed of the first conveyor is faster than the running speed of the second conveyor to move stacks of product on the first conveyor away from the stacking device at a faster speed than stacks of product on the second conveyor.

Abstract: A measuring gage for determining the thickness of a non-metallic material utilizes an inductive sensor positioned on one side of the material to be measured and a metallic object placed on the opposite side. The output of the sensor is used to determine the distance between the sensor and the metallic object, and hence the thickness of the material. The movement of the sensor and the metallic object can be computer controlled to map the thickness of the material along a predetermined path and produce a cross-sectional thickness profile. The output of the sensor can be used in conjunction with a computer controller responsible for adjusting the size of a score line to prepare an airbag deployment section in a vehicle trim panel.
