A sewing machine includes at least one needle bar, a threading motor, a threading mechanism, a processor, and a memory. The threading mechanism is configured to pass an upper thread through an eye of a sewing needle. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include making one of a setting that prohibits operation of the threading mechanism and a setting that does not prohibit the operation of the threading mechanism. The processes include switching the operation of the threading mechanism by prohibiting the operation of the threading mechanism in a case where the setting that prohibits the operation of the threading mechanism is made, and permitting the operation of the threading mechanism in a case where the setting that does not prohibit the operation of the threading mechanism is made.

A sewing machine guiding tool includes a presser foot, a holder and a gauge. The presser foot includes a bottom wall and a rear support. The bottom wall is formed with a needle-passing hole and with a slit extending from the needle-passing hole to the front end of the bottom wall. The rear support is connected to the rear end of the bottom wall. The holder, attached to a presser bar of the sewing machine, holds the presser foot pivotally about a horizontal axis. The gauge, supported by the rear support to be slidable in parallel to the horizontal axis, includes a ruler plate and a guide portion. The ruler plate has a surface marked with a scale. The guide portion extends from the ruler plate. The ruler plate is disposed above the bottom wall with its surface inclined to become higher as proceeding rearward.

Hopping foot for a maneuverable quilting machine. In some embodiments, an example hopping foot may include a presser bar shaft configured to couple to a presser bar and a base attached to the presser bar shaft. The base may define a left straight edge, a right straight edge, a front straight edge, a bottom surface configured to hop onto and off of a fabric, and a needle opening configured to allow a needle to reciprocate into and out of the fabric through the needle opening.

It is intended to improve texture of a decoration using a stitch line while improving workability in sewing for forming the stitch line at a skin material, to promote manufacturing efficiency as compared to formation of a stepped shape only by sewing, and to reduce the number of steps. A skin material is used for a conveyance seat, and is molded using a die. The skin material includes a linearly-extending stepped portion having a stepped shape transferred from the die, and a stitch line sewn along the stepped portion. The stepped portion serves as a guide upon formation of the stitch line.

A hopping foot assembly for a sewing machine having a needle comprises a hopping foot base and a hopping foot arm. The hopping foot base is shaped to include a needle opening that extends axially therethrough relative to an axis. The hopping foot arm extends from the hopping foot base. The hopping foot arm is configured to be coupled to the sewing machine to fix the hopping foot base relative to the sewing machine.

Sewing machine ankle assemblies having a resilient member for attaching a presser foot are disclosed. According to an aspect, a sewing machine ankle assembly includes an ankle comprising an upper portion and a lower portion. The lower portion defines at least one structure configured to receive an attachment mechanism of the presser foot. The sewing machine ankle assembly also includes a resilient member comprising an upper end and an opposing lower end. The upper end is attached to the upper portion of the ankle. The lower end is positioned beneath a portion of the attachment mechanism of the presser foot when the attachment mechanism is received by the at least one structure of the ankle such that the lower portion of the resilient member exerts a force on the portion of the attachment mechanism in a direction towards the at least one structure of the ankle.

A stitching system includes a jig capable of joining two shoe parts and capable of being used in an automated stitching machine. The jig includes a lower member capable of being operably coupled to the automated stitching machine and an upper member also capable of being operably coupled to the automated stitching machine. The two shoe parts are held in place between the lower member and the upper member. The lower member, the upper member and the two shoe parts therebetween are moved by the automated stitching machine in accordance with a pattern stored in the automated stitching machine.
