摘要:
A bound document has front, back, and interior sheets with spine edges. The document has a binding strip and fasteners binding the sheets and the binding strip together. The strip has a flexible substrate with a face-attachment portion through which the fasteners are driven, and a wraparound portion that is bent so adhesive on the wraparound portion contacts the back sheet farther from the spine edge of the book than the feet of the fasteners. The strip also has a first spacer affixed to the interior surface opposite the face-attachment portion so that a fastener area is defined, the spacer at least as thick as the protrusion of the heads of the fasteners above the face-attachment portion.
摘要:
The invention relates to a sheet transport device (1) comprising a first and a second opposing transport units (3, 5), each comprising at least one circulating conveyor belt (15) and one vacuum suction device (9, 11) that is in relation with the conveyor belt, said vacuum suction devices being individually actuatable so as to attract a sheet (19), located between the transport units, to the one or the other conveyor belt. Such a sheet transport device is used, for example, in a printing machine. The invention also relates to a method for transporting a sheet to this sheet transport device.

摘要:
Treating a transport mechanism (5) for transporting print material (2) in a printing press (1) that uses toner in which oil-bearing substances (27) adhere to the transport mechanism (5). A cleaning device (30) is provided with at least one cleaning element (33) movable relative to the surface of the transport mechanism (5) for application of at least one oil-repelling substance (37) that reduces the adherence of the oil-bearing substances (27) to the transport mechanism (5). Accordingly, this cleaning element (33) can strip the surface of the transport mechanism (5) of oil-bearing substances (27).
摘要:
A carrier or substrate for a photoconductor to be used for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, is prepared wherein the surface of the carrier supporting the photoconductor, used to form a barrier layer, is oxidized, preferably by etching and/or anodizing. The oxidized surface of the barrier layer is sealed with a sealing material following oxidation, and a preservative or impregnating agent is used as the sealing material.
