Abstract:
An electrode for dielectric barrier discharge treatment of a substrate includes a tubular housing that is made of electrically insulating material and has a bottom wall facing the substrate, two side walls extending away from the substrate, and a top wall connecting the distal ends of the side walls. The electrode further includes an electrically conductive electrode member disposed inside the housing and having a plate that engages an internal surface of the bottom wall of the housing. The electrode has two wings formed in one piece with the plate and engaging internal surfaces of the side walls of the housing.
Abstract:
A sheet stacking device for forming a stack of subsequent sheets includes a rotatably arranged flipping element and a closed-loop shaped friction element. The flipping element includes a slot at its circumferential edge for accepting at least a portion of a sheet. In a first rotation zone, the flipping element is able to accept the sheet into the slot and, in a second rotation zone, the sheet is conveyed out of the slot onto the top of the stack of subsequent sheets. The friction element is moveably arranged on the flipping element, and is controllable to move into a first radial position and a second radial position. In the first radial position, the friction element does not apply a frictional force to a sheet in the transport path and in the second radial position, the friction element does apply a frictional force to a sheet in the transport path.
