$q\bar{q}$ pairs needed to break the rope, but a larger effective string tension. As is generally expected, this implies larger strangeness and baryon fractions. In addition our model also gives nontrivial effects on the $p_\perp$-dependence for different particle ratios, which to some extent mimic effects of transverse flow. In this paper we present results where the model (with some approximations) is compared to LHC $pp$ scattering data, with encouraging qualitative agreement. In the future we plan to also study effects of rope formation in collisions with nuclei. We begin this article with a recapitulation of the relevant ingredients of the Lund string fragmentation in [section [\[sec:stringfragmentation\]]{}]{}, before we describe the basic idea of the rope model in [section [\[sec:ropes\]]{}]{}. Then we describe the proposed “final-state swing mechanism” together with the implementation of our rope model in the interface between and [P8]{}in [section [\[sec:the-dipsy\]]{}]{}. In [section [\[sec:results\]]{}]{} we present some first results, and finally in [section [\[sec:outlook\]]{}]{} we summarize our findings and give an outlook.

For completeness, we end the article with a number of appendices. There we first summarize details in the model ([appendix [\[app:dipsy\]]{}]{}) that are important for our rope implementation, and also summarize the relevant colour algebra needed
