Abstract

A cradle mechanism comprises ramp 10 and transverse end plate 11 provid peripheral support to a loose supply roll 13. Paper 14 is pulled by an incrementing mechanism (not shown) from the top of roll 13. A loose drag roll 15 applies a downward force to the supply roll which minimizes the movement of the supply roll up the ramp 10 when incremented by the take-up mechanism. A polymer coating, such as TEFLON*, on the upper surface of ramp 10 reduces the friction between paper 14 under drag roll 15 and under supply roll 13. This allows supply roll 13 to unwind without unraveling in the event the incrementing force on paper 14 causes the supply roll and drag roll to be momentarily moved up ramp 10 and out of contact with end plate 11.
