Device for a pleating machine to drive the pleating blade and the control lever of the blade support

摘要

In an apparatus for guiding the folding blades (3,5) and for actuating the tilting arm (24) of a blade bar (4) mounted pivotably on the jib (10) of a blade shaft (11), a reversible individual drive (23) with a pivoting member (21) which can move a rocker (16) to and fro between two positions serves for actuating the tilting arm (24). Mounted pivotably on the rocker (16) is an intermediate member (14) on which the tilting arm (24) is articulated on a pivot pin (13) at a distance from the point of articulation of the intermediate member (14) on the rocker (16). The geometry of the articulated chain formed by the jib (10), the pivoting member (21), the rocker (16), the intermediate member (14) and the tilting arm (24) is, at the same time, selected so that the tip of the particular folding blade (3) is guided along on the upper or lower contact plate (7,8 ) of the pleating machine as a function of the position of the pivoting member (21).
