Manual Cutting in Apparel Industries:STRAIGHT KNIFE CUTTING MACHINE: Motor power drives the reciprocating blade and operator power drives the knife through the lay. CUTTING MACHINE PARTS INVOLVED IN CUTTING 1. Knife/Blade 2. Sharpener 3. Motor 4. Fabric presser 5. Base plate 6. Moving handle 7. Transport handleComparatively cheap & and can be cut many plies at a time Higher lay of height cannot be cut very easily. Round corners cannot be cut more precisely than even round knife. Production speed is very good. Garments components can be directly separated from fabric lay.High speed of the machine causes high risk of damage. Faulty knife could damage fabric layer. Motor weight creates knife deflection which may be creates faulty pieces. Risk is high for physical damage of operator. Knife required replacing.

Now a days Automatic Cutting machines are used in garment industries.

Automatic Cutting in Apparel Industries:Features: The GERBER S-91 high-ply cutter provides users with benefits of speed, flexibility, and accuracy - in addition to saving fabric and labor. Up to 76 mm (3 inches) of compressed fabric can be consistently and accurately cut, utilizing Gerber's high-efficiency vacuum hold-down system. Cutting precision is assured with features such as automatic knife sharpening and Knife Intelligence, which automatically accommodates for blade deflection and variable knife-speed control. The S-91 is the most reliable cutter for high-volume, high quality cutting, ideal for heavy duty materials such as denim.Our proprietary CAD program for upwind sails was developed in house. It accurately calculates the exact dimensions for every panel in the sail, nests them on the sailcloth, and sets up the tool path for the Gerber cutter blade to follow. The Gerber cutting surface is made from closely packed bristles. The cutting blade drops into the bristle surface, allowing us to cut from 1 layer of oz Nylon, to 10 layers of 8 oz Dacron, as well as any laminate sailcloth. The cloth is held in place by a vacuum pressure of 3 pounds per square foot throughout the table surface, higher in the cutting area. This holds the cloth firmly on the table without distortion as the blade passes through. Precise blade placement and NO fabric distortion while cutting are the unique features of our Gerber cutter, and both are absolutely necessary to cut panels to an unmatched accuracy of 8/1000 of an inch!
