Abstract
An arrangement is disclosed for stabilizing and reinforcing the connection between the resilient hold-down control springs and their underlying couplings in a Jacquard loom. The junction between two portions of the spring is strengthened by using a flared-out arrangement beneath an aligning comber board through which the springs pass in a vertical orientation. In this manner, the connected heddle/spring is maintained in a reliable axial position and the spring is able to function in its resilient holding-down capacity by a technique which generates reduced stress at the key point where the spring is retained.
Claims5
In a Jacquard loom for producing woven patterns in fabric by selectively positioning a first group of yarn elements relative to a second group of yarn elements, under the control of predetermined program means, including a plurality of heddles linked individually to corresponding ones of said first group of yarn elements, spring means for exerting downward tension on each of said heddles, and alignment means including a plurality of apertures through which said spring means extend at their lower ends regions, said alignment means defining a retaining position for said spring means;
- the improvement comprising that:
- (a) each said spring means is a unitary spring having a plurality of interconnected helical coils, and
- (b) each said spring includes a first segment connected to a respective one of said heddles and of a diameter to pass through a respective one of said apertures, and a second segment located below said alignment means and of a larger diameter then said first segment, said second segment being in substantial contact with a portion of said alignment means and incapable of passing through said aperture.
