Abstract
A Venetian blind cutting machine comprises a machine stand on which a cutting device and the clamping device are mounted. The cutting device has a blade which moves back and forth to execute the cutting of the Venetian blind. The pivoting center of the blade is higher than the position at which the Venetian blind is arranged. The lower half cutting edge of the blade provides the downward and the inward cutting forces to execute the cutting of the Venetian blind. The revolution rate and the feed rate of the blade are regulated by a controller in accordance with the nature of a material of which the Venetian blind is made.
Claims12
A machine for cutting a Venetian blind comprising:
- a machine housing;
- a cutting device mounted in the machine housing;
- a blind supporting frame mounted on the machine housing for holding the Venetian blind;
- a clamping device mounted on the machine housing at a first end of the blind supporting frame for holding a first end of the Venetian blind in a cutting path of the cutting device;
- a circular blade on the cutting device driven in a linear reciprocating motion on guide rods which forms the cutting path;
- the guide rods being engaged on an upper side of the machine housing;
- said upper side of said machine housing comprising a front portion having a pivotable protective cover being disposed adjacent to the blade and parallel to the cutting path and side portions being disposed on each end of the cutting path and perpendicular to the front portion;
- wherein at least an upper half portion of the blade above an axis of rotation is entirely enclosed by said upper side of said machine housing when said protective cover is closed;
- wherein said axis of rotation through a center of the circular blade is spaced above and parallel to a longitudinal length of the Venetian blind to create a downward and inward cutting force on slats of the Venetian blind which pull the slats together when the Venetian blind is cut.
