A method is provided for the design and manufacture of tufted patterned textiles having selected yarn densities that may vary for different pattern palette colors and in different areas of a pattern.

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 machine includes a sewing machine motor, a control device and a wearable sensor. The sewing machine motor is a vertical movement driving source of a needle bar. The control device controls the sewing machine motor such that a sewing pitch is set to be a predetermined value. The wearable sensor is attached on a body of an operator of the sewing machine to detect a moving amount of an attached portion of the wearable sensor. The control device controls the sewing machine motor based on the moving amount of the attached portion detected by the wearable sensor such that the sewing pitch is set to be the predetermined value.

A sewing machine having a device for manually changing a feed dog (10), including the feed dog (10) and a feed-dog holder (30). The feed-dog holder (30) is disposed in an arm bed (103) that is associated with the sewing machine, and the feed dog (10) is receivable in a clearance (31, 81) of the feed-dog holder (30). The feed dog (10) that is located in the clearance (31, 81) has a support face (15) which may be disposed parallel with the surface of a sewn-product support which may contain a needle-hole plate (113) or be configured as a needle-hole plate (113), the sewn-product support and/or the needle-hole plate (113) may at least partially be formed by the surface of the arm bed (103), and the support face (15) may be received in an opening (140) of the needle-hole plate (113). The feed dog (10) is fastenable in the clearance by a fastening element (40, 82, 83) or of a setting element (50) such that the support face (15) is alignable so as to be substantially parallel with the surface of the sewn-product support or of the needle-hole plate (113). The fastening element (40, 82, 83) or the setting element (50) is releasably held in the feed-dog holder (30).

Computerized methods of creating embroidery including capturing embroidery instructions, receiving instructions at an embroidery engine, creating planned patterns of stitches, and outputting instructions for stitching, including instructions for printing colors onto a thread before stitching. Color may be printed in a gradient or gradually faded, for example, from a start color to an end color, or from a start color to an intermediate color and from the intermediate color to an end color. Color may be gradually faded from a start location to an end location or from a start location to an intermediate location and from the intermediate location to an end location. Varying shades of colors may be printed, patterns may be repeated, outlines, segments, and vectors may be used, and intermediate stitch color may be determined based on number of stitches or vector length. Some embodiments allow a user to change embroidery instructions while reapplying unchanged instructions.

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.

A delivery device with actuators for delivering yarns in a textile machine, controllers for controlling the actuators, which comprise produce measurement signals as a measure of the drive torque of the actuators, and monitors for monitoring the tensions of the yarns using the measurement signals. Additionally, at least one embodiment concerns a method for monitoring the tension of yarns which are delivered in a textile machine by means of actuators, comprising producing measurement signals as a measure of the drive torque of the actuators, which is a measure of yarn tension, and monitoring the tension of the yarns using the measurement signals.

A knee operated lifting mechanism for a presser foot of a sewing machine is fixed on a body of the sewing machine, the body is provided with a presser-foot shaft, the knee operated lifting mechanism is drivingly connected to the presser-foot shaft, so as to consequently drive the presser foot to move up and down. The knee operated lifting mechanism includes a knee pushing device, a cable and a rotary member. The knee pushing device includes a knee pushing plate to be operated by a user. The cable is drivingly connected to the knee pushing plate to control the rotation of a drive shaft and the rotation of the presser-foot shaft as well, which consequently controls the upward and downward motion of the presser foot, and thus considerably simplifying the structure of the knee operated lifting mechanism.

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.

Preparing textile products by establishing, by a textile product system, data types, valid values for each data type, and valid relationships between the data types encompassing specification of textile products for manufacturing and visualization of the textile products. Receiving, from a user, a first data set comprising values of data types and relationships between the data types associated with at least one of manufacturing of a particular textile product and visualization of the particular textile product. Determining whether the received first data set conforms to the data type, data value, and data relationships valid for at least one of the manufacturing of textile products and the visualization of textile products.
