A sewing system serves for sewing seams which the multi-dimensionally in space. A needle-bar upper part of a sewing head is mounted so as to be pivotable in a driven manner about a needle-bar longitudinal axis. A gripper lower part is mounted so as to be pivotable in a driven manner, and in a manner synchronous with the needle-bar upper part, about the needle-bar longitudinal axis, in the sewing-head lower part. Motor components for driving the movement of a needle bar, for pivoting the needle-bar upper part, for driving a gripper in a manner synchronous with the needle bar and for pivoting the gripper lower part are disposed outside the needle-bar upper part and outside the gripper lower part. Parts to be sewn that are topographically non-uniform are also rendered accessible.

The invention provides a sewing device which can precisely and evenly carry out a great variety of sewing works further with a good productivity. The sewing device has a sewing machine (2), and a dual-arm robot (7) having a first arm (5) and a second arm (6) which can operate an object to be sewn (4) supplied to a sewing motion portion (3) of the sewing machine. The duel-arm robot is provided with a camera which can image the sewing motion portion. Further, the sewing device is provided with an image processing portion which processes an image information acquired by the camera, and a command transmitting portion which transmits commands to an arm control portion controlling the first arm and the second arm on the basis of a processing result of the image processing portion.

An electronically controlled pattern sewing machine automatically detects and programs coordinates of a sewing line of a sewing object even if the coordinates of the sewing line are not manually set and programmed, thereby reducing costs and making skilled workers unnecessary. A jig disposed on the sewing machine to support a fabric thereagainst and having a pattern-shaped through hole formed thereon. A sensor coupled to one side of the sewing machine to sense coordinates of a periphery of the pattern-shaped through hole of the jig. A memory to store the coordinates sensed by the sensing part. A controller to automatically convert the coordinates stored in the storage into sewing coordinates. A setting part to set sewing functions on the sewing coordinates and a panel box to operate the sewing machine according to the sewing coordinates converted by the controller and the sewing functions set by the setting part.

The present disclosure relates to manufacturing an inflatable structure. There is determined one or more contours of at least a portion of an inflatable structure to be manufactured. There is further provided a drop stitch fabric having a first layer and a second layer tethered by drop stitches. Moreover, there is provided along at least a portion of the drop stitch fabric one or more fixation lines comprising coupling means fixating the first layer to the second layer, the one or more fixation lines corresponding to the one or more contours. Furthermore, the drop stitch fabric is coated, wherein one or more coating layers cover at least the one or more fixation lines. The disclosure also relates to an inflatable structure manufactured according to the foregoing, and a control system for controlling said manufacturing.

A sewing machine of the present embodiment comprises a movement amount detector which detects a movement amount of fabric, a sewing machine motor serving as a rotary drive source of an upper shaft which applies vertical movement to a needle bar, a shaft angle detector which detects a shaft angle of an output shaft of the upper shaft or the sewing machine motor, and a controller which controls the sewing machine motor based on the detection of the movement amount detector and performs controls of maintaining a constant stitch length. The controller performs controls of maintaining the constant stitch length, by a movement amount of the fabric detected by the movement amount detector in a shaft angle section where a sewing needle is not stuck into a cloth, based on the detection by the shaft angle detector.
