Abstract
In a document processing apparatus, transport means feed a document along a track past one or more processing devices such as scanning means or printing means. The apparatus includes first and second corrugating rolls (44, 45) between which a document is fed. The rolls (44, 45) are arranged to produce a plurality of corrugations (122) in the document (120) prior to the document reaching the processing device or devices. The corrugations (122) are shallow, being not more than one millimeter in depth, these corrugations (122) producing satisfactory stiffening and straightening of the document (120) while having no adverse effect so far as reading information from, or printing information on, the document (120) is concerned.
Claims4
An apparatus comprising:
- at least one processing device;
- transport means for feeding a document along a track past said at least one processing device;
- and
- corrugating means for producing a plurality of corrugations in the document prior to the document reaching said at least one processing device, said corrugations extending generally parallel to the direction of feed along the track, and serving substantially to straighten the document in the direction of feed;
- said corrugating means including a plurality of first rolls respectively associated with a plurality of second rolls, a document to be corrugated passing between said first rolls and said second rolls;
- said second rolls being mounted so as to be movable towards and away from said first rolls between a first corrugating position and a second non-corrugating position.

- transport means for feeding a document along a track past said at least one processing device;
- and
- corrugating means for producing a plurality of corrugations in the document prior to the document reaching said at least one processing device, said corrugating means producing in a document corrugations having a depth of not greater than one millimeter, said corrugations extending generally parallel to the direction of feed along the track, and serving substantially to straighten the document in the direction of feed;
- said corrugating means including a plurality of first rolls respectively associated with a plurality of second rolls, a document to be corrugated passing between said first rolls and said second rolls;
