Abstract

This article presents the theoretical background for the arrangement of horn gears in maypole braiding machines in order to act as equivalent larger gears. The theoretical analysis is verified with numerical simulation and experiments. After review about the state of the art, an analysis of the process for one specific configuration of horn gears is given. This analysis demonstrates how a set of horn gears can be arranged to work as an equivalent to a larger one horn gear. The braiding equation is checked as remaining valid for such extended configurations, too. The theoretical result is verified using numerical simulation for all cases and practical validation for several variants. The theoretical rules give a clear extension of the current braiding knowledge and make the design of complex configurations of braiding machines more systematic and clear.

Highlights

  • Maypole braiding is a process of interlacement of at least three yarns, building linear or shell-like structures used in a wide range of applications.[1]

  • The main problem in the development of these structures is that the machine development and the carrier arrangement are done by trials and errors and the fundamental theoretical background is not well developed

  • This work presents a step in filling this gap – it presents the theoretical analysis of equivalent extended horn gears and its application in maypole braiding

Summary

Introduction

Maypole braiding is a process of interlacement of at least three yarns, building linear or shell-like structures used in a wide range of applications.[1]. Kyosev[8] proposed the method and software ‘Texmind Braiding Machine Configurator’[9] for simulations of the carrier motion for any arbitrary arrangement of horn gears, not limited to square sets of four slot horn gears.
