ABSTRACT:
Using a punching tool for a strapping unit for producing an auxiliary-free connection of ends of a strapping band, the tool having a recess of different widths, in the case of which at least one section of a recess-bounding wall is provided with a rounded portion in the region of at least one change in width, on the one hand, the intention is to make a fixed closure between the band ends possible. On the other hand, the intention is for this tool to be produced as easily and cost-effectively as possible and, in addition, for uniform cutting forces to be made possible. For this purpose, it is proposed that the rounded portion is of circle-arc shape with a certain radius, and that the largest width of the recess is equal to or less than four times the radius of the wall.
