Abstract (en)
There is provided sheet printing apparatus (l) having at least one printing station (4) for sheet printing, sheet transfer means (7, 8) for conveying printed sheets (3), and radiation curing means (ll) arranged to direct curing radiation onto sheets conveyed by said sheet transfer means, said sheet transfer means comprising a sheet gripper means (7) whose length extends tranversely across the sheet feed direction of the sheet transfer means, wherein said gripper means has attached thereto and spaced therefrom a shielding plate (l3) extending along at least part of the length of said gripping means, said shielding plate having as the surface remote from the gripper means a radiation reflecting polished surface which serves to shadow said gripper means from directed radiation from said radiation curing means. In the apparatus of the invention the shielding plate (l3) serves to reduce overheating and heat damage resulting from the exposure of the sheet gripper means to ink-curing radiation. In a particularly preferred embodiment, the shielding plate is provided on its inner surface with fins or vanes (20) which serve to direct heated air towards the sides of the printing apparatus thus particularly assisting the avoidance of component overheating.
