Abstract

A dispenser for flexible sheet material having a reserve roll that automatically moves in the dispensing position when the dispensing roll is almost exhausted. The sides of reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is pushed downwardly into contact with a driving roller during rotation. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism. The perforating mechanism is assisted through the perforating stroke by a spring mechanism. The sensing roll is halted by a roll stop mechanism including a pivoted stop link and an anti-reverse pawl.

Claims

1. In a dispenser for flexible sheet material having an intial roll of sheet material;

a reserve roll of sheet material, and apparatus to advance and perforate a web of said sheet material;

a method for automatically feeding a web from the reserve roll through the dispenser, comprising the steps of;

(a) displacing said reserve roll to a dispensing position after said Initial roll has been exhausted a predetermined amount; and

(b) buckling the leading edge of the web of said reverse roll whereby said web ultimately is enmeshed in said advancing and perforating apparatus and thence directing outwardly from said dispenser.

2. The method of claim 1, wherein the buckled leading edge of the web of said reserve roll is entrained with the as yet unexhausted trailing edge of said initial roll.

3. The method of claim 2, comprising the additional step of discharging said initial roll to an inoperative position prior to displacing said reserve roll to a dispensing position.
