CAD/CAM SYSTEM FOR JACQUARD WEAVING
A CAD/CAM system in the company is the answer to the requirements of a market in evolution which needs new timely ideas for fabrics, a complete Pattern Books, and a quick answer to the customers demands.
An internal CAD/CAM system offers many advantages to answer efficiently to the customers solicitations, to guarantee projects reservedness and to allow the technological independence necessary for all Firms which want to be leader and to innovate on their own market.
The program is equipped with a technical sheet which guides the user through the entire process, from the acquired image to the card generation. It contains the drawing technical specifications and the fabric data (loom and weaving data) used in all phases of the textile process. The technical sheet is stored together with the graphic information and is saved in such a way that it can be used for other similar fabrics.
The Images Menu offers a variety of functions of image manipulation; from the ones
for the scanner management to the ones of image retouch. JACQ-
The images can be easily cleaned by fast functions such as Colors Decreasing and Random Dots Removal.
The cleaned images are converted into Point Paper Design by a guided procedure where
the user assignes the textiles parameters (Density of wefts/cm and threads/cm) ,
height and length of the fabric
to weave; on this basis the system calculates the remaining data and , if they are correct, generates the Paper Point Design which is displayed on the screen in normal or repeated mode. In the repeated
mode all drawing functions are propagated on all graphic repetitions; in this way the user is able to refine the base module until the full drawing is completed. The system provides several sophisticated
drawing functions divided in 5 categories (colour handling, drawing
manipulation,areas selections, copy/paste operations, drawing tools). All functions are active with the multidesign module which allows mirroring functions, auto protection and automatic colours exchange. Graphic functions are saved and can be restored up to 32 times backward (depending on Ram Memory).
PAPER POINT DESIGN
Complete, powerful, easy to use on PC CAD/CAM . It can project any Jacquard fabric and generate floppy disks in any loom format. It can be completed by the integrated management of the local network for direct transmission of Designs to Jacquard Controllers.
LABEL–DESIGN : CAD/CAM FOR LABELS
CAD/CAM on PC for the programming and realization of labels weaved on Jacquard Looms. It is a special version of JACQ-
CAD/CAM utility for contour smoothing and drawings manipulation. It allows raster image conversion in vector format for easy forms modification, rotation of elements, parts displacement and many other graphic functions.
VIRTUAL LOOM : FABRIC SIMULATION
Realistic graphic simulation of the fabrics starting from the floppy disks for the Jacquard controllers. It is indispensable for project checks and to generate fabric variants.
JACQUARD PRODUCTS SUITE
System for the creation of written selvedges to realize on Electronic Jacquard Looms.
RIBBON : DESIGN WEAVED RIBBONS
System for the creation of weaved ribbons to realize on looms equipped with electronic Jacquards Controllers. It allows to acquire the images from scanner.
Complete system for the management of local networks of Jacquard Loom controllers; based on a PC server and a high speed ETHERNET network.
System of weaving monitoring. Continuous real time control of actual activities on looms. Recording of all unproductive periods and with the relative stop causes. Production yeld display.
COLORS TO WEAVE NOTE
After the graphic modifications are done, the system allows to develop a Paper Point
Design with Weaves for any fabric class, either with constant density or variable
one (lancé). The PPD with Weaves generation is led by: a table of colors and weaves
LOOM SETUP AND CARDS GENERATION
Starting from the Paper Point Design with Weaves obtained during the previous phase, the system generates electronic formats specific for the looms on which the fabrics must be realized. The Loom Data Setup phase allows to describe the characteristics and the configurations of any Jacquard loom type. At the end of the electronic format generation, the card is displayed and it can be further modified.
Data pertaining to the Technical Sheet Module, together with the data processed by
the system when calculating the PPD with Weaves, are used for the evaluation of the
threads requirement and the related costs.
COSTS AND MATERIAL CALCULATION
The program allows to create simple and compound Weaves in a graphic interactive
mode. For all the weaves the verify effect simulation is offered. It is possible
to display the weft and or warp profiles of the Weaves and to modify the Weaves acting
on the profiles. After having modified a compound Weave, the system regenerates the
base Weaves in a way consistent with the modifications.
It is the last phase floppy disks are generated for the most diffused type of Jacquard
loom Controllers (such as Staubli, Bonas, Grosse, Muller). It is also possible to
directly transmit Design data to the controllers (using the JD&N system JACQ-
It manages the printout of all the documentation connected to the CAD use (Weaves,
