Abstract: A device for acting on a material web using ultrasonic includes an ultrasonic unit which has a converter a booster and a sonotrode, and a counter tool. The material web is guided through a gap between the sonotrode and the counter tool and acted upon by the sonotrode. The ultrasonic unit is adjustable relative to the counter tool by way of a movable carriage, and the booster is firmly connected to the carriage. A support supports at least one side surface of the sonotrode and guides the sonotrode in the longitudinal direction thereof.

Abstract: In a device for applying spatially limited, flexible elements (26) to a continuous web (14), in particular for applying holograms, the speed of the continuous web (14) is reduced In the application zone and the flexible element is applied at this time.

Abstract: The invention relates to a conveyor device, including a conveyor belt for transporting workpieces out of a cutting or stamping device and a placement star wheel for putting upright the workpieces, which are delivered horizontally upright. The placement star wheel is mounted downstream of the conveyor strip. Conveyor bands which grip the workpieces on top and/or at the bottom are provided between the conveyor belt and the delivery star wheel. The conveyor bands move at essentially the same speed as the conveyer belt and the placement star wheel and are arranged in such a way to guide the workpieces into the receiving elements of the placement wheel.

Abstract: A method and a device for joining a sealing foil to a web of material, the sealing foil is brought to the web of material, and the web of material, together with the sealing foil, is moved along the surface of a support body. The sealing foil is connected in a simple manner with the web of material in that the web of material, along with the sealing foil, is passed between an ultrasonic unit and the surface of the support body, and that ultrasonic energy is introduced into the web of material and/or the sealing foil by means of the ultrasonic unit for connecting the sealing foil with the web of material.

Abstract: In a blade support, particularly for circular blades, having a positioning arm and a blade support device rotatably fixed to it for the blade, access to the blade is made simpler by providing the blade support device with a mandrel reaching through the blade and having a bearing flange for the blade, and with a quick-action lock.

Abstract: A rotary punching machine comprises a pair of punching tools, namely a rotary punching tool with punches arranged on its circumference and a rotary counter tool, which co-operates with the latter, with dies in the form of punching bushings arranged on its circumference. One of the punching tools (1) and the counter tool (3) has a radial groove (12) on its circumferential surface between the respective individual punches (2) or the individual punching bushings (4), the depth of the groove being greater than the depth of penetration of the punches (2) into the punching bushings (4).
