摘要:
A method of imaging an imprinted substrate on a printing press is provided. The method comprises sensing light reflected by the substrate using a contact image sensor to produce data representative of the imprinted substrate. The substrate has been imprinted with different colors at a plurality of printing units of the printing press. Each printing unit comprises a plate cylinder. The method further comprises storing the data representative of the imprinted substrate in a memory.
摘要:
An inspection system for inspecting an imprinted substrate on a printing press has a light source, a contact image sensor, and a processor. The light source is configured to illuminate a portion of the substrate which has been imprinted with different colors at a plurality of printing units of the printing press. The contact image sensor has a plurality of sensing elements. Each sensing element senses light reflected by a corresponding region on the substrate to produce data representative of the corresponding region printed on the substrate. The processor is configured to receive the data representative of the imprinted substrate and to compare the data representative of the corresponding region printed on the substrate with stored reference data.

A web inspection module is described for scanning an imprinted web in a printing press. The web inspection module includes a light source for illuminating a portion of the web, a contact image sensor having a plurality of sensing elements, and a processor for receiving and processing image data representative of the imprinted web.
摘要:
A drive-through strapping machine for use in securing materials together on a pallet and for securing stacked pallets together and a method for securing materials together for shipment or storage and for delivering those materials to a location. The drive-through strapping machine provides a strapping device for wrapping straps around a pallet or stacks of pallets while the pallets are supported on a forklift. The strapping machine also provides for movement of the forklift through the strapping machine for delivery of the pallets to a storage location or for shipment.
摘要:
A system for controlling the lateral position of a web in a web-fed printing press having a printing unit. The web has a series of printed images thereon. The system includes an optical scanner for sensing the lateral position of an image on the web and for generating a first signal. The system also includes an edge sensor which senses the lateral position of a corresponding web edge and which generates a second signal. A controller processes the first and second signals to produce a control signal. The systems also includes a positioning means responsive to the control signal for laterally positioning the web.
摘要:
An apparatus for registering a cover with a book block. The apparatus includes a book block holder, a cover feeder, and a lateral positioning device for laterally positioning a cover fed from the cover feeder. A cover position sensor positioned to detect a lateral position of the cover. A control mechanism is operatively interconnected with the cover position sensor. An adjusting device is provided for adjusting a relative lateral position between the lateral positioning device and the book block holder.
摘要:
A system having a printer for customizing signatures delivered and processed on a conveyor line in groups of completed books of variable thickness includes an arrangement for maintaining a constant distance between the printer and the books regardless of the thickness of the books in order to preserve the quality of printing on the books. The system further includes an arrangement for selectively diverting completed books to a stacker, a mail stream conveyor and a poor quality book conveyor.
