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.

Jacq-Design is the ideal solution to keep pace with the times and to secure oneself technological independence, because of the easy of use, the performances richness and the limited investment needed.

Jacq-Design is a Jacquard CAD/CAM System for design and weaving of fabrics for Fitting, Clothing, and related areas. The System has no limitations of articles dimensions, of textile complexity and of fabric type. It operates under Windows operative system and can exchange data with any other Windows application and in any standard graphic format.

TECHNICAL GUIDE

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-DESIGN uses images in Tiff standard format,  to which any image acquired by scanner, by electronic catalogs, Internet or by other graphic applications in Windows environment can be converted.

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).


IMAGES MANAGEMENT

PAPER POINT DESIGN

JACQ-DESIGN : CAD/CAM JACQUARD

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-DESIGN.

VECTORIZE : VECTOR DESIGN

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

SELV-DESIGN : WRITTEN SELVEDGES

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.

JACQ-LINK : NETWORK CONNECTION OF
JACQUARD LOOMS

Complete system for the management of local networks of Jacquard Loom controllers; based on a PC server and a high speed ETHERNET network.

JACQ-MON : LOOMS MONITORING

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 association (Colors-To-Weaves Note), and by a Weaving Note derived automatically (constant density case) or by wefts-to-colors association (Lancé fabrics).
The colors-to-Weaves association is completely led and in every moment the system allows the display of the Point Paper Design, of the Weaves and of their effect. It is possible to recall either simple Weaves and compound Weaves; the Point Paper Design generation with weaves is displayed while it is created and the result is an image which can be manipulated for possible checks and retouches. When the PPD with Weaves is generated, it is possible to use functions for the search and the correction of floats effects and for its correctness verification.

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-LINK, for Staubli controllers).


It manages the printout of all the documentation connected to the CAD use (Weaves, Designs, Colors-to-Weaves Notes, PPD with Weaves). The printouts can be realized in many different formats : the print page and the images are printed in true dimensions or in pre-defined dimensions decided and configured by the user. UTIL also manages the projects files filing and the backups with incremental mode.
