Abstract
An automated multiple-needle sewing device which comprises a table, a guide plate movable on the table, a multiple-needle sewing mechanism, a feed roller mechanism, a yarn cutting mechanism, and a guide plate returning mechanism. A material to be sewn is placed on the guide plate and undergoes the sewing, feeding and yarn cutting processes in an automated manner. The guide plate is automatically returned to an initial position for mounting a new other material to be sewn. The feed roller mechanism includes a lifting device for lifting or raising a shaft and feed roller(s) away from contact with the material and guide plate being fed.
Claims11
An automated multiple-needle sewing device, comprising:
- a multiple-needle sewing mechanism;
- a table extending in a forward direction and rearward direction relative to said multiple-needle sewing mechanism, wherein a forward area and a rearward area are defined on said table in relation to said multiple-needle sewing mechanism;
- a guide means upon which a material to be sewn is securely mounted, said guide means being moveable on said table along a longitudinal direction thereof, passing through said multiple-needle sewing mechanism;
- a feed roller mechanism disposed at said rearward area, said feed roller mechanism including:
- (a) a pair of shafts extending transversely of said table;
- (b) at least one feed roller fixed on each shaft of said pair of shafts;
- said feed roller being normally disposed for contact with both said guide means and material in order to feed them;
- (c) a gear means provided on said pair of shafts, one of said gear means being operatively connected with a driving source;
- and
- (d) a lifting means for lifting one of said shafts upwardly so as to raise said feed roller out of contact with said guide means and said material thereof;
- a yarn cutting mechanism which is disposed more rearwardly than said feed roller mechanism at said rearward area;
- and
- a guide means returning mechanism which is disposed more rearwardly than said yarn cutting mechanism, said guide means returning mechanism being for returning said guide means to said forward area.
