Abstract

An apparatus for trimming the width of blinds of the type having a headrail, and a bottom rail and blind slats, and having a support body with a headrail opening, and a bottom rail opening, and a blind slat opening the blind components being insertable into their openings from one side of the support body, a die located adjacent to the support body, a headrail cutting recess in the die, guides on the support body for the die, enabling the die to move relative to the headrail opening between two positions and a bottom rail and blind slat cutter operable to cut the bottom rail and the blind slats. A modified apparatus can be used to trim the width of a vertical blind having a headrail and control rods. Also disclosed is a method of trimming the width of blind, having a head rail, a bottom rail and blind slats.

Claims33

Dependent claims

An apparatus for trimming of blinds of the type having a plurality of blind components including a blind headrail having a generally rectangular three sided channel shaped profile, a blind bottom rail having a first-generally arcuate profile, and a plurality of blind slats, each having a second generally arcuate profile, and comprising;

a support body, said support body defining a blind headrail opening, a blind bottom rail opening, and at least one blind slat opening, said blind headrail opening, said blind bottom rail opening, and said at least one blind slat opening being aligned along a transverse axis;
at least one partition in said blind slat opening for separating said blind slats into groups of blind slats whereby said groups of blind slats are cut in sequence;
a blind headrail cutter located alongside said support body;
a blind bottom rail and slat cutter for cutting said blind bottom rail and said blind slats, said bottom rail and slat cutter being movable along a cutting axis, wherein said blind slat opening is located between said blind headrail cutting opening and said blind bottom rail cutting opening, spaced apart from one another along said transverse axis;
a guide on said support body for movably supporting said blind headrail cutter, said guide defining a predetermined blind headrail cutter movement axis, whereby said blind headrail cutter is movable relative to said blind headrail opening in said support body;
a first driver connected to said blind bottom rail and slat cutter for moving said blind bottom rail and blind slat cutter to cut said blind bottom rail and said blind slat groups;
and,
a second driver connected to said blind headrail cutter for moving said blind headrail cutter.

5 more elements

A blind cut-down apparatus for trimming the slat length of a blind having at least a head rail component, and blind slat components suspended from the head rail, and comprising;

a blind holding plate having a head rail opening for holding a head rail component;
a first blind slat opening for holding a first group of blind slat components;
and
holding them in position for cutting;
a second blind slat opening, spaced from said first blind slat opening, for holding a second group of blind slat components separate from said first group, and holding said second group of blind slats in position for cutting;
a blind slat group separator between said first and second slat openings for holding said first and second slat groups apart from one another.
at least one clamp for clamping said blind components in position in said first and second blind slat openings, for cutting;
at least one cutter moveable relative to said blind holding plate, for cutting at least one of said head rail and said first and second groups of blind slats extending through said first and second openings and clamped in said holding plate, and
a movement transmission for moving said at least one cutter.

6 more elements

An apparatus for trimming blinds of the type having a head rail, a bottom rail and a plurality of blind slats, said apparatus being adapted to trim the length of said head rail, said bottom rail and said blind slats and comprising:

a support body defining first and second openings, each of said first and second openings being adapted to receive at least one of said head rail, said bottom rail and said slats;
a first cutter positioned proximate said first opening and adapted to cut a predetermined amount of material extending through said first opening;
a second cutter positioned proximate said second opening and adapted to cut a predetermined amount of material extending through said second opening;
a lost-motion mechanism linking said first and second cutters such that during one portion of the movement of a selected one of said first and second cutters the other of said first and second cutters remains stationary, and during a second portion of movement of said selected one of said first and second cutters, the other of said first and second cutters moves in conjunction with the movement of said selected one of said first and second cutters.
