Abstract
An apparatus for cutting a window covering comprises a saw blade for cutting a plurality of different types of window coverings. A first controllable drive moves the saw blade into engagement with a window covering selected from the plurality of different types of the window coverings. A second controllable drive for rotates the saw blade. A preferred saw blade feed rate and a preferred saw blade speed for each of the plurality of different types of window coverings is determined. The first variable drive and the second variable drive are controlled based on the preferred saw blade feed rate and the preferred saw blade speed for the window covering being cut.
Claims22
A method of cutting a window covering in a cutting machine of the type having a saw blade comprising:
- identifying a type of window covering;
- determining a preferred operating parameter of the saw blade for the type of window covering wherein for the type of window covering, the preferred operating parameter comprises a first operating parameter for a first component of the type of window covering and a second operating parameter for a second component of the type of window covering wherein the first operating parameter controls the saw blade based on one of a period of time of operation of the saw blade and a distance of travel of the saw blade before using the second operating parameter;
- controlling an operating parameter of the saw blade to be equal to the preferred operating parameter;
- cutting a window covering using the saw blade.
