Abstract
A filament drawing device for drawing a plurality of strands simultaneously in a downstream direction through a plurality of groups of dies, there being one die for each strand. Each group of dies is held in a retaining mechanism including first and second portions which are adapted for movement toward and away from one another. When the retaining mechanism is in the open position, wherein the portions have been moved away from each other, any one of the plurality of dies may be removed without removing or displacing other dies in the same group. When the portions are moved toward each other, they overlie at least partially the dies in the group and thereby retain them in position.
