摘要:
An improved pleating machine and method for creating a variety of pleated patterns that are not limited to repeating variation. Pairs of pleating blades move forward and rearward in a pleating motion. During the forward pleating motion, the pleating blades advance the material and create folds therein. The pleating blades then force the folds against heated cylinders resulting in pressed pleats in the material. Displacement of the pleating blades prior to the forward pleating motion causes a reverse pleat in the material; lack of such displacement causes a forward pleat. A cross-member moves to an engagement position and back to a resting position prior to each forward pleating motion. Switching devices, such as sliding blocks, slotted cams, or switch pins, attached to the cross-member selectively engage push-up rods which, in turn, selectively displace the coinciding pleating blades. The switching devices are electronically controlled to alternate positions. The method includes functionally applying the above-described pleating machine.

A textile web corrugating machine comprises a support table along which a textile web is transported, a folding plate disposed above the support table for folding in a generally zig-zag fashion the textile web then as it passed below the folding plate, a retainer member positioned above the support table in face-to-face relationship with the folding means for urging folds successively formed on the textile web into a web transport passage positioned downstream of the support table with respect to the direction of transport of the textile web, and a compressing unit disposed along the web transport passage for applying a compressive force to the successively formed folds from above and also from a lateral direction.
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).
