Abstract
A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.
