The sewing machine includes a projector, a processor, and a memory storing computer-readable instructions that cause the processor to perform processes. The processes include generating processing of generating a first image including a first object representing a first sewing pattern and generating a second image including a second object representing a second sewing pattern. The first sewing pattern is at least a part of the sewing pattern and is a state in which the sewing is incomplete. The second sewing pattern is a part of the sewing pattern and is a state in which the sewing has progressed further than the first sewing pattern. The processes include projection processing of, after causing the projector to project the first image, switching the projected first image, during the sewing, to the second image, and causing the projector to project the second image.

A sewing management system includes a sewing device that transmits a production management information including an identification information of an operator and an operation information of a device main body; and a management device that manages the production management information by a process unit of a product sewn in a sewing line or a component forming the product.

A sewing error management device includes a display portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to acquire an error image obtained by drawing an occurrence position of an error on a sewing pattern. The acquiring the error image is based on coordinates representing a formation position of a sewing stitch being sewn at a time point when the error occurs in sewing of the sewing pattern formed by a plurality of sewing stitches. The acquiring the error image is also based on an image showing a shape of the sewing pattern. And the computer-readable instructions further instruct the processor to display the acquired error image on the display portion.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate multi-patch multi-view systems that may reduce errors associated with material thickness, object height, perspective. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate virtual light curtain systems that may enable features such as detection of ingress or egress of objects into an operational area and gestural input. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.

The present disclosure discloses an automobile seat cover capable of releasing a safety air bag and a sewing technology of a seat cover. An air bag detonation edge is sewn. The air bag detonation edge is defined on the seat cover side cloth and a sewing position between the seat cover backrest cloth and the seat cover rear cloth. A braid with a width of 4 MM is sewn at the air bag detonation edge through an air bag bottom thread and an air bag upper thread. The common computer automobile is reformed, the number of needles and the needle pitch are strictly controlled by biasys computer software, the tension of the air bag bottom thread and the tension of the air bag upper thread are strictly controlled through a tension controller. The upper half part of the seat cover is integrally sewn.

A method of forming a patterned carpet in a tufting machine with a sliding needle bar (4) comprising a plurality of needles (5). The method comprising analysing desired pattern data to determine if a problem condition is present for a particular arrangement of tufts in the desired pattern data based on the relative location of at least two stitches in the desired pattern data. Changing the colour of at least one tuft from that required by the desired pattern data to create actual pattern data in which the problem condition is eliminated (or alerting to a user). The problem condition may be the tufts will be spaced by less than a predetermined amount. Alternatively, it may be that a needle (5) forming a tuft in a transitional line is not required to form a tuft for a more than a predetermined number of reciprocations of the needle bar after to the transitional line.

A seam allowance guide aide system including a needle plate of a sewing machine containing vertical and horizontal lines with colors; a vertical line is provided to be aligned with the needle default position on the sewing machine. Colors are used to represent a standard measurement known and accepted in the sewing industry. The seam allowance guide aide is fixed and non-removable to said needle plate.
