Window covering sizing method and apparatus

摘要

A method and apparatus for cutting a vertical window covering are disclosed. One method of operating a window covering cutting machine comprises retaining a window covering in a package such that a first end of the window covering is located at a known first position relative to the package. An engagement element is provided on the package that is located at a known second position on the package. The engagement element is moved a distance from a saw to obtain a final dimension of the window covering where the distance is calculated using the first position and the second position.

主权项

1. A method of operating a window covering cutting machine comprising:
providing a saw; retaining a window covering in a package such that a first end of the window covering is located at a first distance C relative to an adjacent package end, providing a computing platform comprising a processor, the computing platform being operatively connected to the window covering cutting machine to control operation of the window covering cutting machine; providing an engagement element on the package that is located at a second distance Z relative to the package end; the computing platform acquiring the distances C and Z and a desired final dimension; the computing platform calculating a third distance Y that the engagement element must be positioned relative to the saw, according to the following equation;
Y=Final Dimension−Z+C, providing an engagement device for engaging the engagement element; the computing platform automatically moving the engagement device to the third distance Y from the saw; the computing platform actuating the saw to obtain the final dimension of the window covering.
