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.
Claims14
An apparatus for cutting a window covering comprising:
- a saw blade for cutting a plurality of different types of window coverings;
- a first variable drive for moving the saw blade into engagement with a window covering selected from the plurality of different types of window coverings;
- a second variable drive for rotating the saw blade;
- a storage medium for storing a preferred saw blade feed rate and a preferred saw blade speed for each of the plurality of different types of window coverings;
- and
- a processor for controlling the first variable drive and the second variable drive based on the preferred saw blade feed rate and the preferred saw blade speed for a particular window covering positioned at the apparatus, wherein the processor is configured to increase a saw blade feed rate or a saw blade speed either (i) after the saw blade has traveled a predetermined distance during a cutting operation, or (ii) after the saw blade has operated for a predetermined length of time during a cutting operation.
