How do computer-guided knives and lasers cut fabric for clothing production?

In the clothing and footwear industry, computer-guided systems have revolutionized how fabric is processed by integrating digital design with automated manufacturing operations.2

Computer-Controlled Knife Systems

Introduced in 1967, these systems secure the fabric lay by covering it with a thin plastic film. A vacuum is then applied through a porous table, pulling the film firmly against the fabric to prevent any movement during the cutting process. Depending on the specific machine, either the knife moves across a stationary lay, or the lay moves forward while the knife operates horizontally.1

Laser-Beam Cutting

Introduced in 1971, laser systems function by using a computer-controlled beam to burn or vaporize the material rather than using a physical blade. This technology allows for the storage of programmed instructions, enabling the efficient production of single garments from a single layer of material. Key benefits include improved cloth utilization, the elimination of size variations, and the ability to fulfill smaller orders more rapidly without needing to accumulate large quantities of inventory.1
