Abstract
A computer reviews card designs for color changes in a fabric pattern that might cause mixed contours in the fabric woven by a Jacquard design. The computer displays problem positions of the card designs that cannot be corrected by correction lift plans and suggests changes to the card designs. When permitted the computer automatically changes the card designs to avoid mixed contours.
Claims27
A method for offering assistance before or during manufacture of pile fabrics in accordance with card designs produced before or during a file being processed to activate a Jacquard machine, the method comprising
- using a computer having an input, a central processor, and a display,
- inputting data from a card design for a fabric pattern,
- on the basis of the data entered, detecting in the card design color changes that might cause mixed contours in the fabric to be woven by the Jacquard machine,
- designating in the processor the color changes in the card design that might cause mixed contours in the fabric to be woven by the Jacquard machine, and
- displaying the designated color changes where a mixed contour occurring in the fabric may be impossible to avoid by a correction lift plan.
A method comprising offering assistance during the manufacture of pile fabrics in accordance with card designs produced before or during a file being processed to activate a Jacquard machine:
- providing a card design for use in a Jacquard machine;
- screening the card design with a computer;
- determining color changes causing mixed contours in the card design that are impossible to be compensated for and avoided by correction lift plans, and
- designating the determined color changes on a display of the computer.
A method comprising offering assistance during the manufacture of pile fabrics in accordance with card designs produced before or during a file being processed to activate a Jacquard machine for preventing color changes in a card design causing mixed contours in face to face woven fabrics:
- screening with a computer the card design from the Jacquard machine color changes likely to cause the mixed contours;
- determining the color changes that are likely to caused mixed contours;
- and
- designating and displaying on a display of the computer the color changes likely to cause the mixed contours that cannot be avoided.
A method for offering assistance during the manufacture of pile fabrics in accordance with card designs produced before or during a file being processed to activate a Jacquard machine, the method comprising
- avoiding mixed contours in color changes in a fabric to be woven in a Jacquard loom,
- providing a card design controlling color changes in the fabric to be woven in the Jacquard weaving machine,
- providing a computer with a processor, an input and a display,
- providing a program in the computer to detect and designate color changes that will produce mixed contours in the fabric from a card design entering the card design of the pattern of the fabric in the input of the computer,
- detecting locations and designating points in the card design where the mixed contour will occur,
- displaying with the display the location of points in the card design where the mixed contours will occur.
A method for offering assistance during the manufacture of pile fabrics in accordance with card designs produced before or during a file being processed to activate a Jacquard machine, the method comprising
- avoiding mixed contours in a pile fabric to be woven in a Jacquard weaving machine by providing a computer,
- providing a program for detecting in a card design color changes that will produce mixed contours,
- entering data of the card design of a pattern of the fabric,
- entering data of a planned weave structure of the fabric,
- entering data of positions of pile frames in a creel of the Jacquard machine,
- scanning the entered data for color changes causing mixed contours
- designating the color changes causing mixed contours, and
- displaying the color changes causing mixed contours.
