This document discusses fabric spreading, which involves smoothly laying out fabric layers according to a cutting marker. There are two main types of spreading: flat and stepped. Fabric can be spread manually by hand or hook, mechanically using a spreading truck operated by hand, or using semi-automatic or fully automatic spreading machines. Proper fabric spreading requires aligning the fabric layers, applying the correct tension, laying the fabric flat, eliminating flaws, ensuring correct layer direction and stability, eliminating static electricity, and allowing easy separation and avoidance of distortion after cutting.

- 3. LEARNING OUTLINE What is spreading? Object of Spreading? Types of Spreading? Methods of fabric spreading? Requirements of fabric spreading?
- 4. SPREADING Spreading means the smooth laying out of the fabric in superimposed layers of specific length. The cutting marker paper is laid in the top of the fabric layers.
- 5. OBJECT OF SPREADING To place the number of plies of fabric to the length of the marker plan correctly aligned as to the length and width and without tension. To cut garments in bulk and saving in fabric the use of multi garments marker plans and the saving in cutting time per garment that result from cutting many piles at the same time.
- 6. TYPES OF SPREADING Flat Spreading Stepped Spreading
- 7. METHODS OF FABRIC SPREADING By hand By hook Spreading truck with the help of operator Semiautomatic Full Automatic Manual Method Mechanical Method
- 8. MANUAL METHOD By hand: Fabric roll is spreaded on the table by two laborers according to the length & width of marker. Sometimes it is done by entering a rod which is made by wood or metal in the center of paper tube which is presented in the center of the fabric roll. By hook: In this process the top of the table on which the fabric is set at 10 angle. The hook which placed on the upper face of the table is 15cm long and the hook is joined with one end of selvedge of the fabric & the other end of selvedge is draped on its weight. The hooks are placed 20-25cm one after another with the same row. The fabric lay is spreaded by matching the check of fabric which is useful. Spreading truck with the help of operator: There is a spreading truck on the one end of the spreading table in which the fabric roll is placed. Then the truck is operated by hand from one end to the other end of the table & with the same time the fabric is open out from the fabric roll and the fabric is spreaded according to the length & width.
- 9. MECHANICAL METHOD SEMIAUTOMATIC Spreading machine is run on the two rails which are placed at two side of fabric spreading table surface and operated by motor. Fabric roll is set in a predetermined place of the machine. Spreading machine is run from one side to the other side f table by using electrical & mechanical motion and fabric is spreaded to make lay. Advantage: Auto ply cutting device. Auto loading and unloading device. Disadvantage: More time required. High labor cost.
- 10. MECHANICAL METHOD FULL AUTOMATIC This is the improvement of semiautomatic machine. There are many advantages of this machine to make fabric lay because, this machine is operated by controlling with the help of robot and micro processor. Advantages: Less time needed for fabric spreading. Less labor cost. o Disadvantages: Skillful operator is needed to operate the machine. Very expensive, so that capital investment is high.
- 11. REQUIREMENTS OF FABRIC SPREADING Alignment of fabric ply. Correct ply tension. Fabric must be flat. Elimination of fabric flaws. Correct ply direction and lay stability. Elimination of static electricity. Easy separation of the cut lay into bundles. Avoidance of distortion in spread. Matching checks and stripes.
