Abstract
A pulling device is configured to grip, after cutting of a sewing material, a suitable portion of the sewing material by means of a grip member, where a leading end portion of the sewing material having been pulled out from a guide device, and pull back the sewing material by movement of the grip member having the sewing material gripped thereby. Thus, the leading end portion of the sewing material, pulled out and extending from the guide device more than necessary, can be minimized to a length necessary for the sewing material to be reliably sewn onto a sewing object at an initial stage of a next sewing operation. In this way, it is possible to minimize a length of a portion of the sewing material that was heretofore wasted without being sewn onto the sewing object.
Claims4
A sewing machine comprising:
- a sewing needle mounted to a lower end portion of a vertically-driven needle bar;
- a guide device for guiding an elongated sewing material to a needle drop position of the sewing needle in response to a sewing operation for sewing the sewing material onto a sewing object;
- a cutting device for cutting the sewing material after moving the sewing object, having the sewing material sewn thereon through lock stitching, so that a sewing end point of the sewing material is moved from the needle drop position to be located at a predetermined position away from the needle drop position and then pulling the sewing material out from the guide device;
- and
- a pulling device for pulling back the sewing material, whose leading end portion has been pulled out from said guide device, after the cutting by said cutting device, and thereby reducing a length of the leading end portion of the sewing material extending out from said guide device.
