Abstract: A tension panel includes a frame, and a retaining device affixed to and retaining respective corners of a display sheet. A stretching and fixing assembly is provided which includes an L-shaped bar formed by two legs joined together to define a bent region of the bar. The legs each have a free end attached to the frame so that the bar is movable from a raised position, through an intermediate position, to a lowered position in which the bar lies essentially flush with the frame. The assembly further includes a resilient member having one end attached to the bent region of the bar, and another end attached to the retaining device for exerting a tensile force on the retaining device when the bar is in the lowered position. The tensile force extends in a direction along an imaginary line that divides an interior angle of the respective corner into two angles, so as to stretch and fix the display sheet on the frame. When the bar is in the raised position, the tensile force is not exerted.

Abstract: A paper sheet transporting method comprises a step of superposing a paper sheet on a reinforcing sheet and a step of affording an electrostatic attractive force between the sheets due to electrostatic charges given thereto. The reinforcing sheet is made of a substance selected from plastics that are of a highly insulating nature and retain the electrostatic charge for a long period of time so as to have a remaining attractive force. A step of gripping the thus electrostatically charged sheets between a pair of transporting rollers is carried out so as to transport the sheets in a tangential direction of the rollers while the sheets are still sticking to each other. The paper sheet is transported by the reinforcing sheet to a work station therefor without producing any deformation or torsion, and the paper sheet is removed from the reinforcing sheet after being processed at the work station.
