Abstract
The invention relates to a method for the connection of pieces of textile fabric, a textile band and a method for producing same. In order to provide a textile band or continuous textile product which is suitable for continuous processing, it is proposed that, for the connection of pieces of textile fabric, a cut edge, at which the threads are essentially bound at the edge, is first formed. The textile pieces are then laid one on the other with an overlap, and are pressed one onto the other between a sonotrode and an anvil, where the anvil and/or the sonotrode have a surface profile with a number of elevations, The textile pieces are connected to each other by introducing an ultrasonic oscillation into the sonotrode, thus welding the textile pieces to one another ultrasonically.

A Method for the connection of pieces of textile fabric, where
- a cut edge is formed at each of the textile pieces, at which threads of the textile pieces are essentially bound at the cut edge,
- and the textile pieces are laid one on the other with an overlap,
- and the textile pieces are pressed one onto the other between a sonotrode and an anvil,
- at least one of said sonotrode and said anvil being provided with a surface profile which has a number of elevations,
- and where the textile pieces are connected by introducing an ultrasonic oscillation into the sonotrode, thus welding the textile pieces to one another ultrasonically.
A Method for the production of a textile band, where
- a textile band is being produced continuously,
- a weaving fault occurs, the fault is cut out,
- and the ends of the cut textile band are reconnected by forming a cut edge at each of said ends, at which the threads are essentially bound at the edge,
- and by laying said ends one on the other with an overlap,
- and by pressing said ends one onto the other between a sonotrode, and an anvil,
- at least one of said sonotrode and said anvil being provided with a surface profile which has a number of elevations,
- and by introducing an ultrasonic oscillation into the sonotrode, thus welding said ends to one another,
- and the continuous textile band thus formed, for further processing, is applied to a suitable carrier or introduced into a suitable container.
A textile band consisting of continuously produced textile fabric,
- where at one or more locations on the band there are connection points, at which connection points two separate portions of the band are connected to one another,
- where the ends of said portions are arranged one on the other, defining an overlap region,
- and said ends are connected to one another by a number of weld connections being formed between said portions, said weld connections being distributed over the overlap region.
A method for the connection of pieces of textile fabric, comprising the steps of:
- providing a first and a second piece of continuously produced textile fabric, where each of said pieces has a length which is substantially greater than a width of said piece,
- forming a cut edge at each of the textile pieces, at which the threads are essentially bound at the edge, said cut edge running in a traverse direction of the textile pieces,
- laying the textile pieces one on the other with an overlap, said cut edges pointing away from one another,
- pressing the textile pieces one onto the other between a sonotrode and an anvil, at least one of said sonotrode and said anvil being provided with a surface profile which has a number of elevations,
- and connecting the textile pieces by introducing an ultrasonic oscillation into the sonotrode, thus welding the textile pieces to one another ultrasonically.
