Claims (1)

[Claims for Utility Model Registration] (1) A device for attaching an elongated edge band to a moving ribbon that wraps the elongated edge band around the edge of a flat ribbon moving in the longitudinal direction, the device for applying the elongated edge band to the edge of the ribbon; a fixed folding device adjacent the edge of the ribbon for folding around the ribbon; and a folding device located in front of the folding device and having an axis of rotation perpendicular to the surface of the flat ribbon. an applicator roller for pressing the edge band against the upper edge of the ribbon; and an elongated edge band towards said applicator roller having an axis of rotation located above the applicator roller and generally aligned with the edge of the ribbon. a guide roll for delivering the ribbon and a device on which said applicator roller is mounted which rotates freely through a plane parallel to the edge of the ribbon, and the delivery of the advancing ribbon and the elongated edge strip rotates the support device. 1. A device for attaching an elongated edge band to a moving ribbon, characterized in that the elongated edge band is pressed onto the ribbon by an applicator roller that is biased in a direction. (2) The guide roll is placed on a support frame, and the support device for the applicator roller is a swing arm pivoted to one end of the support frame, and the free end of the support device has an applicator roller. A device for applying a narrow edge band to a moving ribbon according to claim 1 of the utility model registration. (2) the advancing ribbon is guided along the edge of the ribbon by a roller having an axis of rotation perpendicular to the plane of the ribbon, said roller being mounted on a longitudinally extending chassis member with adjustable lateral position; 3. The device for attaching an elongated edge band to a moving ribbon as claimed in claim 2, wherein the chassis is formed adjacent to the support frame and its lateral position is adjustable. (4) includes an applicator wheel having a conical surface at the top, said wheel being tilted so that the conical surface is parallel to the bottom surface of the ribbon, so that the bottom surface of the edge of the elongated edge strip is pressed into position; Claims 1, 2 or 3 of the claims for utility model registration characterized by:
2. A device for applying a narrow edge band to a moving ribbon according to any one of Items 1 to 1.
