Inverter having a slow speed drive mode for improved reliability

Abstract

A substrate inverter, comprising: an inversion channel having an input path having an input nip and output path having an output nip; input drive means for driving a substrate into said inversion channel means in an initial incoming direction so that a leading edge and trailing edge of said substrate pass by said input nip until said trailing edge of substrate reaches a first position in said inversion channel; output drive means for driving said substrate out of said inversion channel in an output direction generally opposite said initial incoming direction; said output drive means includes a xnip for engaging said leading edge of said substrate when said substrate is in said first position; a Controller, responsive to said output drive means, for adjusting speed of said output drive means so that substrate is driven a first speed until said trailing edge of substrate reaches a second position in said inversion channel, and second speed when said trailing edge passes said second position.
