Abstract
ABSTRACT
An apparatus for, and method of, producing a plurality of venetian blinds simultaneously. There are at least two adjacent blind producing stations, each supporting a head rail, a bottom rail,and each having a plurality of suspended blind ladders. Ahead of the stations, from a continuous supply of slat material, a length corresponding essentially to the width of the plurality of blinds is cut, and openings at locations corresponding to the ladders in the finished plurality of blinds are punched. The cut length of slat material is fed into the blind stations, through the ladders of the blinds, until the slat material engages a stop, and between adjacent stations the slat material is cut.
