摘要： Provided are: a sewing device provided with a sewing mechanism which performs sewing on a work to be sewn using a sewing-machine needle, while holding the work to be sewn in a state of being shaped in a predetermined shape on a plurality of seating portions arranged in a sewing direction; and a sewing method. When the seating portions are withdrawn from the work to be sewn so as to avoid interference between the sewing mechanism and the seating portions, a guiding mechanism enables movement in a first withdrawing direction for avoiding a first undercut portion of the work to be sewn, and movement in a second withdrawing direction for avoiding a second undercut portion of the work to be sewn.

摘要： The invention relates to a chain stitch sewing machine comprising stitch-forming sewing elements including at least one needle head (1) and needles (6) arranged on the needle head and at least one gripper shaft and gripper hooks arranged on the gripper shaft, wherein the needles (6) and the gripper hooks respectively form a sewing element pair and are driven in a manner such as to perform preferably chain stitches and especially double chain stitches in a sewing material arranged on a sewing material support, respectively using a needle thread and a gripper thread. To reduce the masses to be moved during the sewing operation, the invention provides that the needles (6) are indirectly or directly connected to the drive (5) and that at least one and preferably more needles (6) can be mechanically decoupled from the drive (5), so that the needle(s) (6) in a position decoupled from the drive (5) is(are) not moved in a translational fashion during the sewing operation and does(do) thus not pierce the sewing material.

摘要： A sewing machine includes a main frame including a needle seat, a beam, and a head supported by the beam. The head includes elements for sewing operation in association with the needle seat. A fixed seat is fixed to the beam and a rotational seat is fixed to the head to turn therewith. The rotational seat and the fixed seats include aligned axial holes. A shaft sleeve extends from the rotational seat and rotatably extends through the axial hole of the fixed seat. The head and the rotational seat are movable relative to the fixed seat between an operative position allowing sewing operation and an inoperative position angularly spaced from the operative position. A distance between the head and the needle seat is increased when the head is moved from the operative position to the inoperative position, allowing easy insertion and removal of thick materials during a sewing operation.

摘要： A combination stitching system including a pneumatic sensing apparatus which operates to assure the presence of a material to be stitched is in a proper location before machine operation is possible is disclosed. The combination system comprises a machine (10) for stitching or sewing a material (30) with thread (26). At least one reciprocating needle (12) receives thread (26) through an aperture (28) for stitching the material (30). A power source (20) is connected by a drive linkage (18) which includes a clutch (21) and which provides reciprocating motion to needle (12). The clutch (21) operates to selectively connect and disconnect the power source from the reciprocating needle (12) by means of an activating means (22). To assure that the reciprocating needle operates only when a work piece (30) is in a position to be stitched, there is also included a pneumatic sensing apparatus (32). Pneumatic sensing apparatus (32) includes a source of pressurized air (34) which is connected to a air gap means (38), an air jet nozzle (40), and a control valve (42). The air gap means (38) operates so that a stream of air is ejected across an open area of the air gap means such that pressurized air from source (34) is provided through the air gap means to the control valve (42). When the air pressure is provided to control valve (42), air pressure is then made available to the actuating means (22) to activate the clutch (21). Air jet nozzle (40) is located in position so that a high pressure jet of air (64) is directed to impinge upon the air stream (50) of air gap means (38).

摘要： A sewing machine having a rotary drive mechanism and a needle bar mounted for reciprocation between upper and lower positions with respect to a looper includes a transmission system operably connected between the rotary drive means and the needle bar to convert the rotary motion of the drive means to reciprocating motion of the needle bar. The transmission system includes a lever pivotally mounted intermediate its ends and pivotally connected at one end to the needle bar, a crank pivotally connected at one end to the rotary drive means, and a pitman pivotally connected between the crank and the other end of the lever to convert the rotary motion of the drive means and crank to reciprocating motion for oscillating the lever and reciprocating the needle bar. The crank is operatively connected to the looper for synchronously driving the looper with the needle bar. The transmission system also includes means for selectively maintaining the line of thrust of the pitman in a first position substantially perpendicular to the lever to transmit motion thereto from the drive means for reciprocating the needle bar and in a second position substantially in alignment with the lever whereby the pitman idles under the influence of the drive means without transmitting motion to the lever or the needle bar.
