Double Feed
Control (DFC) Double Feed Control is the sensor that measures the thickness of a
sheet to check if the inserting system does not accidentally take more
sheets than intended. DFC sensors exist on Feeders (double sheet
detection). Currently, DFCs on Formax inserting systems perform
relative measurements, which means that they need a cycle to 'learn'
the thickness of a sheet.
Also the length of the document is measured so partly overlapping
sheets will be detected.
Double Parallel
fold The double parallel fold is a type of fold where the document is first
folded halfway and the resulting folded set is again folded halfway.
This fold is illustrated in the picture below. The position of both folds is
adjustable.
Envelope The envelope is the packaging of a mail set. Window envelopes are
envelopes that have a transparent section through which the address
on the address carrier can be read. Besides the normal top-closing
window envelopes there are also bottom-closing envelopes.
Face down Situation in which the front of a sheet is facing downwards when
placed in a document feeder.
Face down
leading Situation in which the front of a sheet is facing downwards and the top
of the sheet is closest to the separation unit in a document feeder.
Face down
trailing Situation in which the front of a sheet is facing downwards and the
bottom of the sheet is closest to the separation unit in a document
feeder.
Face up Situation in which the front of a sheet is facing upwards when placed
in a document feeder.
Face up leading Situation in which the front of a sheet is facing upwards and the top of
the sheet is closest to the separation unit in a document feeder.
Face up trailing Situation in which the front of a sheet is facing upwards and the
bottom of the sheet is closest to the separation unit in a document
feeder.
Feeder A Feeder is a Module for the input of documents to the inserting
system. The Feeder separates documents sheet by sheet from the
stack of documents in the feeder tray.
Feeder linking The ability to load two feeders with the same document type where
(cascade mode) the Inserting System automatically switches to a second feeder when
the first feeder is empty and vice versa. In the meantime the first
feeder can be refilled, so the inserting system can keep running
without having to stop to refill the feeders.
Feeder tray Part of the feeder that contains the stack of documents.
