Marker

The program supports all known types of lay – face up, face down, face to face, in fold and round cloth. The laying mode, most frequently used on a factory, is set by default.  Depending on a type of laying, the program controls pattern rotation, their placement and composition.

 

For convenience, the program has two types of pattern output: basic and special. In the basic mode all patterns selected for layout are output taking into account the number of cut details.  A special mode of pattern output is used, when many sets of small patters must be laid out, using the width of cloth in the most optimal way. In this case, control over sets which are used is switched off.

 

Using EDA allows speeding up process of production preparation, as well as providing reliable control of information accuracy.  The system has a common database of models and layouts, latest version of patterns are always included in the layouts; in other words, when a constructor makes any changes to a pattern, patterns in a layout also change. Naturally, this can lead to overlap of patterns; the program will display a warning about this prior to sending a layout to a plotter.  Aside from overlapping, the system displays a warning that not all pieces are in a layout. This can happen, if a constructor adds pieces to a model after a layout is created.  Reports of operations with a model and layouts are developed while a model is prepared for production.  These reports can give information about who worked with a model or layout at a workplace, for how long, which operations were performed.
 

In some factories, operations of creating and managing layouts are organized within the limits of a company order.  This is convenient, if models are repeated frequently over a long period of time.
 

The program allows drafting selected pattern layouts on a plotter, with preliminary formation of a drafting queue.  It also allows printing layout diagrams (mini-markers) on a printer, as well as sending to print information about areas of pattern sets.

 

When creating a layout, it is possible to grow pattern size with required values in length and width around the entire contour.  This is convenient when working with shrinking fabrics and printed fabrics.
 

Print can contain a combination of basic drawings of checks, horizontal and vertical stripes.  This allows working with any actual print.  Now, two techniques for creating layouts on a printed cloth are used in production: increasing a pattern for future fitting of a print to each pattern and superposing separate patterns points with a print. As experience of program usage has shown, both methods are actually used at the same time.  A connection between gashes and print is set; to account for fabric distortion in lay, patterns are increased by 0.5-1 cm. Such a combination allows generating required cut amount with minimal usage of fabric and time for cutting adjustment.

 

When a layout for automatic cutting is created, there is an option to join several patterns into one, and to cut a block of several patterns for further cutting adjustment on a cutting complex.

 

If a layout must be created on a fabric with some types of defects (stripe of a different color or any defect on an entire length of a fabric roll), the program allows entering and displaying them on the screen, blocking pattern layout on defective areas. 

 

 

For operations with patterned fabric, or when using remnants, the program allows creating layouts, which consist of several sections.  A section is a finished part of a layout, which can be repeated several times.  An operator can select a number of section repetitions to ensure composition of an item.

 

To provide a rational material usage, the program allows creating layouts on account of different composition of patterns (for example, small patterns are laid out separately and in bigger numbers, than in the basic lay). In other words, an individual height of fabric lay is selected for each section of a layout, but at the same time the program controls composition of patterns, and it is not disturbed as a whole.
 

 

While working with a layout, it is possible to create several pattern groups and use them as a separate pattern.

 

The program speeds up considerably the process of creating layouts, similar to the ones existing in the database.  By our data, up to 70 percent of layouts can be created in a semi-automatic mode, using templates of previously created outlines as a hint. This mode is used when creating layouts of the same model for different sizes or cloth width.
 

 

The program has a number of functions for optimization of automatic cutting: pattern numbering, direction of pattern tracing, point of knife entry.
 

 

Using algorithms of automatic pattern layout allows considerable reduction of time in marker operations, because in this case the main function which must be performed is only setting parameters for layout performance.  Automatic layout in Julivi system is done by using a sub-program «Automatic-Mark», which is integrated in any configuration of the program «Mark»; this way, manual modes of a layout also remain.
Full scale functional automatic pattern layout is performed:
- on account of lay type (face to face, face down, face up). Control over grainline direction in a pattern is performed differently for various types of lay;
- setting grainline rotation and maximum distortion value during automatic layout for each pattern.
- on account of partially laid out patterns. Laid out patterns can be automatically moved or blocked from movement as per operator’s preference.
- allows using super-blanks, created on cloth.
- for fabrics with prints, takes into account blanks, placed on a top cloth.
- takes into account sections of patterns, set by an operator, which machine must not use in layout.
Package of layouts for automatic application and processing overnight is created.  All options of set arrangements and order width with the following processing by the machine and displaying information about optimal compositions of sets and width are generated.
