Abstract
Precut and punched fully formed slats for a venetian blind are mounted upside down in a stack on a slat magazine cradle disposed below the assembly station of a venetian blind assembly apparatus, and are picked up, one at a time, by a suction cup and fed in between two endless feed belts which pass around a roller so that the slats are fed the correct way up into the assembly station.
Claims6
A venetian blind assembly apparatus for assembling a supply of fully formed blind slats to at least two ladder cords by individually introducing said slats between adjacent cross rungs of said ladder cords where said apparatus has a slat feeding device for individually feeding slats to an infeed end of a slat ladder cord assembly unit and a machine base supporting said feeding device and assembly unit;
- said feeding device comprising:
- (a) a headstock upstanding from one end of said base;
- (b) a slat magazine cradle disposed longitudinally of and mounted on said base below said assembly unit and capable of holding a stack of fully formed slats having leading ends disposed adjacent said headstock;
- (c) means mounted adjacent said headstock for individually picking up slats near their leading ends from said stack and presenting the leading ends sequentially to said headstock;
- and,
- (d) means within said headstock for redirecting and propelling slats presented thereto to the infeed end whereby said slats are inverted as they travel from said cradle to said infeed end.
Apparatus according to any preceding claim, wherein said means within said headstock comprise a pair of endless belts having working flights able to receive a slat therebetween and redirect it into said assembly station.
Dependencies are inferred from the claim text.
