Device for presenting weft yarns on a rapier weaving machine

Abstract

A device for presenting weft yarns ( ), ( ) to two (or more) rapiers provided above one another of a weaving machine, comprising two yarn carriers ( ), which are movable between a receiving position, in which each yarn carrier ( ) is able to receive a respective weft yarn ( ), ( ) to carry along this yarn, and a presenting position in which each yarn carrier ( ) is able to present a weft yarn ( ), ( ) carried along to a respective rapier in order to insert this yarn into a shed. The presenting arms ( ), ( ) are rotatable above one another in respective intersecting planes of movement. Preferably, the upper presenting arm ( ) is rotatable in a horizontal plane of movement, while the lower presenting arm ( ) is rotatable in a plane of movement that is inclined downwards in the direction of the presenting position. With a similar presenting device the weft yarns can be taken up very close to the fell of the fabric and cut through, waste selvedges becoming unnecessary and weft yarns can be saved. This device functions well at high weaving machine speeds.
