Inkjet printing machine for printing individual sheets

An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system defining a transport track for transporting the individual sheets through the printing station, along a transport direction. The transport system comprises a plurality of gripper conveyors (150) running along the transport track for holding the individual sheets during a printing process in the printing station. Each of the gripper conveyors (150) comprises an energy storage (161) for providing energy for operating a gripper mechanism (171) of the gripper conveyor (150). The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

Protective barrier coating for tubes and cores

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

FRONT END CONVEYOR HAVING ADJUSTABLE ENTRANCE SUPPORT

A front end conveyor has an upstream end and a downstream end, a lower deck including a plurality of primary sheet supports and an upper deck including a plurality of sheet guides. Upper portions of the primary sheet supports lie in a first plane and the sheet supports and sheet guides define a sheet transport path for moving sheets in a sheet transport direction. A pivotable sheet support extends from an upstream end of the lower deck and has at least one surface lying in a second plane. The pivotable sheet support is pivotable from a first position in which the second plane forms a first angle with the first plane and a second position in which the second plane forms a second angle with the first plane, the second angle being different than the first angle.
