Method of Die fabric cutting machine

Working Principle:

Die is prepared with metal strip according to the shape of pattern.Steel strip and forged die are used as metal strip. One end of the strip is sharpened and tie bar is placed to the other end.The die press generally has a cutting arm supported be a single pillar at the back of the machine. It swings to the side to allow the placing of dies on top of the fabric.The downward cutting stroke of the press should be so controlled that the edge of the die just penetrates the cutting pads or surface in order that fibers of the lowest ply are completely separated. The spread is cut into sections to allow transport to cutting the pad.The gap between the two dies 2 to 4 mm are placed when dye is placed on fabric lay.

Features or machine description:

1      The main components of die cutting machine is-

•   Cutting table,
•    Ram head,
•    Die,
•   Motor,
•   Method of driving ram,
•   Controlling arrangement of ram height.

2       Die cutting machine is mainly two types-

•       Clickers,
•       Presses.

3     The die is a knife in the shape of a pattern periphery including notches.

4           It involves pressing a rigid blade through the lay of fabric.

    

Die cutting

Advantages:

       It provides a high standard of accuracy of cutting.

       Die cutting offers much faster cutting than knife cutting.

       Suitable for knitted fabric.

       Suitable for cutting sharp corners.

Disadvantages:

        Not suitable for higher production.

       The capital cost of large area die presses is high.

       Greater uses of fabric in machine i.e. more fabric wastage.

       Power lose is high.

       Labour cost is high.
