Design of Weave Pattern Model for the Selection Box Driving Software

Abstract

A PC driven electronic selection box, simply Selection Box, together with its driving software, is designed to replace perforated card feed pattern system in a jacquard mechanism used on classical weaving looms. A new Weave Pattern Model for the Selection Box’s driving software is developed and presented in this paper. The developed Weave Pattern Model provides access to a weave pattern and serves as an underlying data structure for the Selection Box’s driving software. Further a feed protocol, by which holes sequence on the perforated card for a given weave pattern is determined, is automated. The dynamic link library, MCreator.dll, keeping the implementation of Weave Pattern Model is developed in C++ language. A small client application, HLChanger.exe, testing the library is also developed. HLChanger.exe, besides testing the library, enables user change Colour Stack of the Weave Pattern Model and thus permitting the visualisation of the Weave Pattern. The library is available from the author on request. An example weave pattern is worked out on this client program and the result is presented at the end.
