11. perhaps because they are visualizing sliding like locking up the tires on a car However it takes very little layer to layer movement to cause large telescopes We can easily calculate the results of micro slippage as follows Let us assume a mere mil 0 001 or 25 microns of movement of one layer upon the next Ifthe web were 2 mils thick representing thick film or thin paper there would be 500 layers in a one inch stack of material The total movement of that inch of material would be 500 x 0 001 or 12 mm While the movement per layer is quite small the accumulated effect is a large dish or telescope If you looked quite close you can sometimes observe this micro slippage on rolls with cleanly slit edges The roll edge has a stair step appearance Also you may uncover adhesive so that the roll edge feels tacky or greasy as the case may be Another reason that people have difficulty accepting the notion of slippage is that certain materials that telescope appear to have high interlayer friction Tissue for example is quite prone to interlayer slippage under arolling nip even though the web web coefficient of friction is around 1 0 The nip in this case may be at the inside of the roll due to supporting the weight of the roll at the core or at the outside of the roll caused by a layon roller or drum In any case the layers in bulky materials such as tissue nonwovens and textiles do tend to slide All one needs to do i

13. several tons while the final product rolls such as a roll of masking tape may be small enough to fit in your hand The problem is that the wound rolls can misbehave even while merely sitting in storage The Challenge Of A Round Roll With Straight Edges Winding a roll that has straight edges can be a challenge in its own right Certainly the web needs to have an adequately level tension profile else bagginess can cause tracking problems Certainly the web needs to have an adequately level gage profile else the roll may telescope to the heavy side while winding Similarly the winder must be aligned mechanically tight and stout enough to avoid excessive deflection The roll must wind without excessive vibration Tension and nip must be set appropriately and tightly controlled These and many other factors must be tended to in order to make straight edged rolls However merely making a roll with straight edges does not mean that it will stay that way We are all familiar with the roll of adhesive tape that may have had straight edges for months Take that roll and put it in the back window of a car parked in the sun It may not take many minutes for the previously well behaved roll to shoot out sideways This defect is given names such as coning plating telescoping and others that are not printable here While not all adhesive rolls do this they all have the tendency to do this Related problems are common with master rol

32. movement is slow because eccentricity or lack of roll edge straightness is low However as the roll center pushes outward the bending moment gathers strength that exaggerates the thrust force Finally the movement slows as the roll pushes sideways enough to relieve much of its stored energy To determine whether poor initial straightness contributes can be simple If the roll is wound with a dished edge the risk of telescoping in storage is increased If the core s edge does not extend to the roll s edge the risk is also increased To determine whether gage profiles contributes is usually simple Ifthe roll moves toward the harder larger side of the roll as measured by gage hardness or diameter then profile is likely involved On many machines the caliper or gage tends to have a smile or frown profile If so the end rolls will be more troubled by dishing during winding and telescoping during storage Driving Force Due To Gravity It is hard to avoid gravity yet this is the driving force that causes rolls to get out of round during storage The roll will sag into an egg shape with core support storage To reduce the force we would need to reduce the diameter of the roll To spread the force out over a wider area we might increase the core diameter The roll will develop a flat spot when stored on its bilge To reduce the force we would again need to reduce the diameter of the roll To spread the force out over a wider
