Abstract:
1. Apparatus for continuously folding a flat plate element along a fold line, said flat plate element having a first section adjacent to and on one side of the fold line and a second section adjacent to and on the opposite side of the fold line, the apparatus comprising means for continuously moving the element in a direction essentially parallel to the fold line thereof, a first impression device and a second impression device, said means for continuously moving the element, moving the element past the devices so that the first section of the element contacts and slides along the first impression device and the second section of the element contacts and slides along the second impression device, the second impression device folding the second section of the element about the fold line during such movement, said second impression device during said folding creating a first force component that acts in a direction perpendicular to the plane of the second section of the element and a second force component extending in the plane of the second section of the element that acts in a direction towards the fold line to press the first section of the element against the first impression device.
