A method and apparatus for cutting and sealing a moving length of a fabric by heating, sealing, and finally cutting the fabric in a linear process to form an even, fused edge. The fabric undergoes a sequence of manipulations efficacious for cutting and sealing the fabric to a desired pattern and edge width. The method and apparatus help to minimize frayed edges on the fabric by bonding and fusing the fibers prior to cutting. The fabric is initially drawn through the apparatus in a predetermined pattern, such as a window blind. A heating portion directs a hot gas onto a section of the fiber desired for creating the edges. The heated section is compressed under a seal, which helps fuse perpendicular and parallel cross sections of fibers. The newly sealed section is then immediately cut with a cutting portion to form at least one fused edge.
