Definitions

• the invention relates to a closure element tape with a plurality of closure elements lined up for closing hose packages.

• a packaging tube is filled with the goods to be packed and then closed at its open ends with a closure element.
• Closure clips made of metal are often used as closure elements, which are initially fed to a packaging device in one piece in a row as a closure element band.
• a closure element is separated from the closure element band and fed to the closure device of the packaging device.
• the metal closure element is bent together in a U-shape around a hose end, and in this way forms a clamp closing the hose end.
• metal closure clips Since the two ends of the metal closure clip are not connected to one another, the closure clips must withstand high bending forces in order to be able to reliably prevent an undesired opening of the hose packaging end. For this reason, only solid metal closure elements can be used. Metal closure elements have the disadvantage of high weight and high raw material costs, and are susceptible to corrosion.
• the object of the invention is therefore to create a fastener tape with improved fastener elements.

• the constructional measures described make it possible to use any material that has sufficient tensile strength as the material for the closure element band. However, the material used no longer has to have any significant bending stiffness, so that the use of metal may be dispensed with.
• the choice of material for the closure element band is therefore no longer restricted to rigid materials, such as metal. Materials can be used that have sufficient tensile strength, but may only have low bending stiffness, as is the case among others. applies to a variety of plastics. When using metal, the closure elements can have a smaller cross section, since they no longer have to be rigid.

This will Combining the closure element into a ring in a closing device is made considerably easier and more reliable.
• Several guide ramps can also be provided at the clamping groove input, which form a multi-sided funnel.

As a result, the end section is folded away from the clamping groove entrance, so that the clamping groove entrance is freely accessible and the penetration of the clamping finger into the clamping groove entrance is not in the way.
