Patent ID: 7913999

Claim:
A resilient belt sheet compiler, comprising: a resilient belt transport for sequentially feeding mixed sheet lengths from a sheet inlet to a compiler tray, the compiler tray comprising a lead edge stop and a trail edge wall; monitoring means, positioned at the trail edge wall of the compiler tray, for monitoring a lead end and a trail end of sequentially fed sheets at the trail edge wall of the compiler tray; a sheet brake, positioned to physically engage sheets only within the compiler tray and responsive to the monitoring means detecting a short sheet, for selectively stalling a trail end of the detected short sheet within the compiler tray, such that the trail end of the detected short sheet abuts the trail edge wall of the compiler tray until a lead end of a subsequent sheet is detected by the monitoring means or subsequent sheets are absent; and a control system, responsive to the monitoring means, for selectively actuating the sheet brake.
