TexMind • TexMind UG (limited liability) was founded 2011 in Mönchengladbach, Germany, as
extension of the previous 10 years free lancer activity of the founder Prof. Dr. Kyosev
• Intensive exchange and cooperation with Hochschule Niederrhein, Mönchengladach
• Team of 3 developers with large worldwide network of cooperation partners
• About 60% of our work is development of custom software for special machines and structures
• Public availble products:
• 2014 Texmind Braider launched
• 2015 Techtextil Frankfurt – Warp Knitting Editor and Braiding Configurator
• 2015 ITMA Milano, 2017 Techtextil Frankfurt, 2017 Open House Herzog
• 2018 Int. Week of Narrow and Smart Textiles – First worldwide version for Software for design of Braiding Machines with Computer Controlled Switches and arbitrary arrangement of the horn gears demonstrated

Braider
• 3D CAD for tubular and flat braided products
4
Braider • Different pattern and diameters possible
5
Braider
• Any floating length
6
Braider
• Any number of yarns/wires in a group
7
Braider
• Any floating length

Combination of different yarns with and widthout twist
10
Force Elongation Diagram
• TexMind Braider calculates specific points of the force elengation diagram of tubular braids

TexMind Braiding Machine Configurator
12
Configurator
• Design custom braiding machine – placing the gears with the mouse on the proper place
13
Configurator
• Place carriers
• And simulate their motion
14
NEW ! • Program the switch changes during the motion and speed up the development of complex profiles
