Definitions

  • the subject invention concerns a synthetic resin strip for the manufacture of profiled Venetian blind slats and a method of manufacturing said strip.
  • Venetian blind slats made from synthetic resin suffer from the disadvantage that they can only be manufactured in certain predetermined lengths. Since such Venetian blind slats usually are produced on other continents than those where the main sales markets for the finished products are positioned the shipping costs are much too high and the delivery times too long for Venetian blinds of non standard dimensions.
  • Venetian blind slats made from sheet aluminium are produced in the form of long strips, for instance in lengths of 500 m, which are wound onto rollers for storage and transport. When Venetian blinds of non-standard dimensions are on order, the slats are cut, punched and shaped from the pre-prepared sheet metal strip. This is a very advantageous method and attempts have been made to apply this method also to Venetian blind slats made from synthetic resin materials which are much less expensive than aluminium. However, these attempts have not been very successful since synthetic resin does not lend itself to shaping using cold working methods as easily as does sheet aluminium. For reasons of economy plastic resin slats can only be manufactured in continuous processes, which makes it impossible to submit each individual slat to a heat working treatment to impart the desired curved or profiled cross-sectional configuration to the slats.
  • the purpose of the subject invention is to provide a synthetic resin strip by means of which it is possible to manufacture strips for Venetian blind slats in long lengths which may be wound onto rollers and be subjected to cold working treatments to impart the final profiled configuration to the slat strips and thereafter be cut.
  • the invention also concerns a method of manufacturing such synthetic resin strips.
  • the grooves are formed in the extrusion process by using an extrusion tool which is shaped with protrusions matching the grooves.
  • Venetian blinds 1 essentially consist of a number of slats 2 which are interconnected by a number of operating strings 3, as appears from Fig. 1.
  • Fig. 2 illustrates the positions of the grooves 4 to produce the profiled cross-sectional shape of the slat shown in Fig. 3.
  • Figs. 4 and 6 show the positions of the grooves to produce slats having the profiled cross-sectional configurations illustrated in Figs. 5 and 7, respectively.
