to engage into and effect cutting of the fabric along the cutting line the roller is mounted on a carriage running along the anvil and is spring biased onto the wire application_number US 20468598 A description an apparatus and method for cutting a sheet of fabric is shown in the figures and comprises a fabric table 10 over which a fabric 11 to be cut is laid so that the fabric is stationary on the horizontal table and laid out ready for cutting across the table is mounted an elongate rigid bar 12 having a flat top surface 13 the beam has sufficient stiffness such that it acts as a supporting surface during the cutting action on top of the horizontal top surface is attached a wire 14 which extends along a center line of the top surface and is attached at each end of the beam by suitable clamping devices schematically indicated at 15 the wire is thus held at tension and straight across the length of the beam the wire is a simple metal wire preferably formed of steel which has a smooth cylindrical outer surface tempered steel is preferred to mild steel as mild steel is more compressible and thus will lose its cylindrical shape more quickly an example of a suitable wire is tempered or semi tempered piano wire the diameter of the wire.
