Patent ID: 7156337

Claim:
Method for intermittently feeding weft yarns with an insertion system to a weaving machine substantially without yarn tension, comprising: forming a tubular yarn winding package of adjacently lying windings on an outer side of a drum-shaped support with a yarn feeding device; conveying the yarn winding package forward along the drum-shaped support in a withdrawal direction; setting free a plurality of the windings from the drum-shaped support at a withdrawal side of the yarn winding package, the freed windings being of equal form and being set free loosely and substantially without generating a longitudinal mechanical tension in the yarn while maintaining a tubular configuration during feeding to the weaving machine; and withdrawing the weft yarn of the freed windings inwardly towards and axially along a tube axis of the tubular configuration to feed the weaving machine, wherein said inward and axial movement of the freed yarn substantially avoids yarn tension during the feeding thereof.
