sheet transport apparatus and method for transporting a sheet in a printing machine
Abstract:
A sheet transport method and apparatus are provided for improving the handling of sheets control in printing systems. This automatic sheet transport system and method includes transporting a sheet in the printing machine via a transport belt circulating in a direction of transport, wherein a sheet contact surface of the circulating transport belt is made of an electrically non-conducting material. The method includes placing a sheet on an area of the transport belt and sucking or holding the sheet to the circulating transport belt by a negative pressure applied through the belt and also applying electrical charges to generate electro-static holding forces between the circulating transport belt and the sheet.
