Japanese Patent JP6636741
Kind Code:
B2
Abstract:
The invention provides a sewing machine which can well perform sewing along a curved line. The sewing machine comprises a first feeding mechanism (30), a second feeding mechanism (50), a control device (90) and a side end detection part (17). The first feeding mechanism is arranged to be adjacent to a sewing position, and feeds to-be-sewn object through a roller which is configured to be in an oblique state. The second feeding mechanism is configured to be on the upstream side in the feeding direction relative to the first feeding mechanism, comprises a feeding body (51) which is in contact with the to-be-sewn object in a position deviating from a rotation center, and feeds the to-be-sewn object along an arc around the rotation center. The control device controls a driving source (33) of the first feeding mechanism and a driving source (53) of the second feeding mechanism. The side end detection part is in the direction intersecting the feeding direction of the to-be-sewn object in the sewing position, and detects the position of the side end part of the to-be-sewn object. The control device and the position, which is detected by the side end detection part, of the side end part of the to-be-sewn object correspondingly control the rotation speed of the driving source of the second feeding mechanism.
