Feeder module

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,
• wherein the feeder module comprises a control unit configured to determine a required vertical displacement of one or more of the loading surface or the lower feed roller in relation to a sheet roller thickness and to actuate one or more of the feeder displacement mechanism or the feed roll displacement mechanism to effectuate the required displacement.
