Abstract
The present invention relates to a feeder module for a converting machine, the feeder module comprises an upper feeder assembly, and a lower feeder assembly comprising a loading surface configured to receive a stack of sheets. The upper feeder assembly (20) comprises a gauge (32), wherein a distance (d1) between a vertical distal end of the gauge and the loading surface defines a clearance through which a lowermost positioned sheet in the stack can pass at a time. A feed roll assembly (34) located downstream of the gauge comprises an upper feed roller (35a) and a lower feed roller (35b). The lower feeder assembly (22) and the lower feed roller are displaceable in the vertical direction.

A feeder module for a converting machine, the feeder module comprising:
- a lower feeder assembly comprising a loading surface configured to receive a stack of sheets and a discharge conveyor, the discharge conveyor being configured to discharge the sheets in a direction of transportation through the converting machine,
- an upper feeder assembly comprising a gauge, wherein a distance between a vertical distal end of the gauge and the loading surface defines a clearance through which a lowermost positioned sheet in the stack can pass, and
- a feed roll assembly comprising an upper feed roller and a lower feed roller, said feed roll assembly being located downstream of the gauge,
- wherein the lower feeder assembly comprises a feeder displacement mechanism configured to displace the loading surface in the vertical direction, and
- wherein the feed roll assembly comprises a feed roll displacement mechanism configured to displace the lower feed roller in the vertical direction.
