Tensengral freely offers the intellectual property we've developed using lace braiding machines and Tensengral Patterning, hoping the knowledge will find it's value and place and inspire further exploration for use in textile and composite manufacturing.
Tensengral patterning is characterized by filament arrangements combined to produce a single filament structure, composed of groups of filaments, whose filament members are linked together, in a repetitious pattern, and whose filaments may be interlaced or linked to bisecting groups of filaments, creating a patterned plexus of filaments that has an open and complex architecture.
HISTORY OF LACE BRAIDING
Lace machine technology can be traced to the 1800's in Europe and the United States. The modern lace braiding machine originated in Germany during the early 1900's and with the exception of a few technical improvements appears to be quite similar to the original. Much like the Maypole machine, bobbins move in a sinuous path around the machine perimeter. However, each horn gear is individually controlled, allowing carriers to reverse direction at each machine cycle, thus permitting almost infinite pattern possibilities. Lace braiding technology and machines are unique for several reasons. They began as the first computer controlled braiding machine utilizing a punch card and Jacquard mechanism consisting of cams and levers to control the motion of yarns. The lace industry was one of the first to exploit CAD systems for facilitating design and customer service.

PROPERTIES OF PATTERNED MATERIAL
Patterned material comprises coefficient, unified, multi-axial filament networks with linked and interwoven strands, whose filament members generally follow spiraling paths, creating a group, or interlaced groups, of tension distributive filaments exhibiting conformal and constrictive qualities.
Braiding machines that produce Tensengral Patterning are often referred to as lace, Jacquard, or Torchon braiding machines. Lace braiding machines are specialized 2-D braiding machines commonly used in the production of fancy or lace fabrics. The method to create a patterned plexus of filaments upon a machine would be to program the machine to direct carriers to cross in front and behind other carriers, subsequently interlacing or linking other filaments. More specifically, the method to create a patterned plexus of filaments on a programmable machine would be to program two or more groups of carriers, whose group members all travel adjacent to neighboring carriers within the group, and whose paths cross in front and behind neighboring carriers, thus linking the filaments which are drawn from the spools. The different groups of carriers would be programmed to travel in bisecting paths and could be programmed to interlace with other strands by traveling in front of one carrier from an opposed group of carriers and behind another carrier from an opposed group of carriers, thus interlacing the groups of filaments.
