Abstract
The invention relates to a device for the preparation and insertion of at least one type of weft yarn into the shed of a weaving machine. The said device comprises a yarn metering-delivering member feeding a storage chamber used for temporarily storing a length of weft yarn before its insertion into the shed. The introduction of the weft yarn into the storage chamber and its extraction to be thrown by means of rotating rollers are effected via a single guiding channel which comprises a zone situated between the throwing rollers and close to the gripping line, said zone overlapping laterally with respect to the rollers and comprising a continuous longitudinal slot.
Claims12
A device for the preparation and insertion of at least one weft yarn into the shed of a weaving machine, comprising:
- a metering-delivering device for feeding weft yarn to a storage chamber for temporarily storing a predetermined length of weft yarn prior to insertion into the shed;
- means for halting the feeding action of the metering-delivering device while the yarn stored in the storage chamber is being thrown into the shed;
- rotating roller means for inserting the weft yarn by throwing a loop of the yarn stored in the storage chamber into the shed;
- gripping and cutting means situated close to the selvedge of the fabric being woven for gripping and cutting the inserted weft yarn;
- a guiding channel for guiding the weft yarn into and out of the storage chamber, said guiding channel comprising:
- a first part extending from said storage chamber towards said rotating roller means and substantially in line with said rotating roller means, and
- a second part extending laterally from an end of said first part closest to said rotating roller means and further extending generally in the direction of said metering-delivering device, said second part having a continuous longitudinal slot formed on a side thereof closest to a gripping portion of said rotating roller means.
