Abstract: A pulse generating device and method are provided. The pulse generating device includes a control device, a first knob, and a second knob. The control device is configured to receive a pulse signal and generate a pulse command. After being actuated, the first knob provides a single pulse of the pulse signal to the control device for triggering the control device to generate a single pulse command. The second knob provides the pulse signal to the control device in a frequency corresponding to a twisted angle of the second knob so as to trigger the control device to repeatedly generate the pulse command.

Abstract: A method for cutting a window blind by using a cutting machine includes the step of (a) displaying data of the window blind on a display by reading a barcode provided at the window blind; (b) inputting the size of a window that is to be installed with the window blind and an installation mode of the window blind by selection, and then calculating and displaying on the display a size to be cut based on the data of the window blind and the size of the window and the installation mode selected; and (c) automatically controlling a positioning mechanism of the cutting machine to move to a predetermined position corresponding to the calculated size to be cut by a processor for stopping the window blind in a cutting position, and then controlling a cutting unit of the cutting machine to cut the window blind by the processor.

Abstract: A multipurpose blind cutting machine is constructed to include a machine base, a first cutter unit and a second cutter unit mounted on the machine base and stacked with each other. The first cutter unit has a circular cutting blade and a cutter drive adapted to rotate the blade and to move the blade in a direction substantially perpendicular to the feeding direction of a blank blind to be cut. The second cutter unit has a locating molds having a plurality of positioning through holes for the positioning of parts of the blank blind to be cut, a cutting-off tool, and a cutter drive adapted to move the cutting-off tool in a direction substantially perpendicular to the feeding direction of the blank blind. A control unit is adapted to selectively control the operation of the first cutter unit and the second cutter unit.

Abstract: A Venetian blind cutting machine is constructed to include a machine base, two blind locating modules mounted on the machine base at different elevations, each of which having a set of through holes for supporting component parts of a Venetian blind to be cut, a blind carriage adapted to carry the Venetian blind to be cut, a carriage for moving the blind carriage to the elevation of one of the blind locating modules for enabling the Venetian blind to be cut to be put in the selected blind locating module for cut, a cutter provided at the other side of the blind locating modules, and a cutter drive adapted to move the cutter across the imaginary axis passing through each of the through holes of the blind locating modules to cut the component parts of the loaded Venetian blind and then to return the cutter after cutting.

Abstract: A multi-module Venetian blind cutting machine is disclosed to include a machine base, and a cutting-off unit and a saw unit respectively mounted in the machine base, the cutting-off unit including a carriage having multiple workpiece positioning tools, the carriage being moved to shift the selected workpiece positioning tool to a working position to hold the Venetian blind to be cut for cutting, and a cutting-off tool driving mechanism adapted to move a cutting-off tool to cut the loaded Venetian blind, the saw unit having a circular saw, and a saw drive adapted to move and rotate the circular saw to cut the loaded Venetian blind.

Abstract: A machine for cutting the Venetian blind comprises a base on which a movable seat is mounted. The movable seat is provided with at least two fixed tools for locating the Venetian blind. The movable seat is driven by a tool driving device to displace, so as to locate a predetermined tool at the working position. A cutter driving device drives a cutter to advance to execute the operation of cutting the Venetian blind.
