Abstract
A shed-forming device in a weaving loom which includes spaced partitions to which are mounted retention hooks controlled by electro-magnets. The electro-magnets are encased in a substantially air-tight manner between adjacent partitions. In the preferred embodiment, oppositely oriented flanges extend from the borders of each partition so as to be engagable with the flanges of adjacent partitions when the partitions are mounted in assembled relationship to thereby form substantially air-tight enclosures.
Claims7
In a device for forming a shed in a weaving loom which includes a plurality of assemblies each of which includes two movable hooks joined by a funicular element and which are selectively engagable by retaining hooks having first portions thereof mounted between a pair of partitions and second portions for engaging the movable hooks, the retaining hooks being controlled by an electro-magnet means mounted between the pair of partitions and intermediate the first portions of the retaining hooks, and wherein the partitions have opposing faces defined by lateral, upper and lower edges, the improvement comprising;
- enclosure means for substantially sealing each electro-magnet means from ambient atmosphere between each pair of partitions to thereby prevent contamination of the electro-magnet means.
In a device for forming a shed in a weaving loom which includes a plurality of assemblies each of which includes two movable hooks joined by a funicular element and which are selectively engagable by retaining hooks having first portions thereof mounted between a pair of partitions and second portions for engaging the movable hooks, the retaining hooks being controlled by an electro-magnet means mounted between the pair of partitions and intermediate the first portions of the retaining hooks, and wherein the partitions have opposing faces defined by lateral, upper and lower edges, the improvement comprising;
- flanges extending generally perpendicularly with respect to said faces and on opposite sides of the partitions along the lateral, upper and lower edges thereof so as to define a generally continuous flanged border for the partitions, the flanges of one partition being selectively engagable with opposing flanges of an adjacent partition to thereby define a substantially enclosed housing therebetween when the partitions are assembled in face to face relationship to thereby enclose the electro-magnet means therebetween and within said casing.
