Abstract
Abstract A method of automatically making pattern cards for Jacquard looms or for controlling the operation of the loom directly in which the pattern or design to be woven is scanned directly and signals corresponding to location and color of changes in such pattern or design are fed to a computer for controlling a card punching machine or the operation of the loom directly.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A method of making pattern cards for operating a Jacquard weaving machine to weave a selected textile design comprising the steps of: a. optically scanning the selected textile design linewise to produce a sequential series of pattern signals varying according to the coloration occurring in the design along the line thereof being scanned, b. delivering said series of pattern signals in sequence to an information storage medium having stored therein a multiplicity of comparison signals previously derived from a plurality of colored textile designs and discriminated by color in said medium, c. comparing each pattern signal in turn with said stored multiplicity of comparison signals to identify the color thereof and generate a figure signal corresponding to the thus identified color, and d. controlling the punching of said pattern cards in accordance with the sequential series of figure signals thus obtained.
Claim 2
Independent Claim
141 words
A method of making pattern cards for operating a Jacquard weaving machine to weave a selected textile design comprising the steps of: a. optically scanning the selected textile design linewise to produce a sequential series of pattern signals varying according to the coloration occurring in the design along the line thereof being scanned, b. delivering said series of pattern signals in sequence to an information storage medium having stored therein a multiplicity of comparison signals previously derived from a plurality of colored textile designs and discriminated by color in said medium, c. comparing each pattern signal in turn with said stored multiplicity of comparison signals to identify the color thereof and generate a figure signal corresponding to the thus identified color, and d. controlling the punching of said pattern cards in accordance with the sequential series of figure signals thus obtained.
Claim 3
Dependent Claim
33 words
The method according to claim 1 wherein said figure signals from step c) are stored in series in an information medium and are subsequently read out to control the punching of said cards.
