English to French Tech/Engineering Paper / Paper Manufacturing apparatus for registering a sheet

Contemporary sy stem s transport a sheet and deliver it at a target time to a “datum,” based on positional measurements from the sheet. That datum , also referred to herein as a delivery registration datum, can be a particular point in a transfer zone, a
hand-off point to a downstream nip assembly or any other target location with in the media handling assembly . Typically, the time and orientation of the sheet arriving in a sheet registration system is measured by sensors located near the input of the registration system. A controller then computes a sheet velocity command profile designed to deliver the sheet at a target time that delivery registration datum.
