Abstract: The sewing machine is configured to prevent a string-shaped material from catching on a nearby component part thereof. A guide member for guiding the string-shaped material toward a sewing position reciprocates in a lateral direction to sew the string-shaped material to a sewing workpiece through zigzag stitching. A restriction member is disposed close to the guide member and has a laterally elongated section having a length corresponding to a range of reciprocation of the guide member. The string-shaped material extending from the guide member to the sewing position is positioned to be located beneath the laterally elongated section of the restriction member. With the presence of the laterally elongated section, when the guide member reciprocates, the string-shaped material being swung left and right by the guide member is reliably positioned (restricted) beneath the laterally elongated section. The restriction member may function as a presser foot too.

Abstract: 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.

Abstract: 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.

Abstract: A needle bar case has a plurality of needle bars. As a main shaft is rotated by a main shaft motor (first drive source), the needle bars are driven in an up-down direction so that a sewing operation is carried out in a conventionally-known manner. Ascending/descending bars are supported on the needle bar case in corresponding relation to the needle bars, and each of the ascending/descending bars is driven in the up-down direction by a motor (second drive source). A cord guide member for guiding a cord material onto a workpiece is mounted to the lower end of any of the ascending/descending bars, in place of a conventional presser foot. Cord sewing or loop sewing of cord material can be performed selectively by changing an ascending/descending stroke of the ascending/descending bar. Thus, cord sewing and loop sewing of the chord material can be performed selectively with a simple construction.

Abstract: The upper side of the sole plate in a sewing machine presser foot is formed with a transversely extending channel for the median portion of a guide which steers the needle during making of a row of stitches adjacent the edge of a marginal portion of a piece of fabric. To this end, the guide has two end portions which extend laterally beyond the respective sides of the sole plate and have downwardly bent tips one of which slides along the edge of a piece of fabric when the sewing machine is in use. The guide can be moved longitudinally to place its end portions at selected distances from the respective sides of the sole plate. A male detent member on the sole plate normally engages a selected graduation of a notched scale on the central portion of the guide to maintain the guide in a selected position. The tips of end portions of the guide are located at a level slightly above that of the underside of the sole plate.

Abstract: A presser foot for a sewing machine comprises a base section (1) through which are formed a needle hole (2) and a trimming knife slot (3) spaced away from the needle hole. A support (4) projects upwardly from the base section, and can be attached to a sewing machine. The lower surface of the base section is formed with a groove (7) extending from a leading edge of the base section between the needle hole and the trimming knife slot and parallel to that slot. A fulling rod (16) lies at least partially within the groove and extends along the groove from the leading section thereof to a point beyond the location of the trimming knife, the fulling rod being secured to the base section in such a way that unobstructed free space is left between the fulling rod and the wall of the groove. The arrangement allows automatic formation of a stepped-back edge between two stitched-together garment sections.

Abstract: A method of manufacturing pantyhose by means of sewing machine using hose shaped leg parts comprises arranging the leg parts in a flattened side by side longitudinal relationship, cutting each leg part along an edge from the waist rim of its panty area up to a crotch leaving a remaining leg portion of each leg uncut so as to form upper and lower plies of each leg cut along their inner opposite edges, sewing the cut edges of the laterally adjacent plies together from the waist rim to the crotch to form a seam, deflecting the outer plies outwardly to overlie the remaining leg portions and continuing to sew the seam by sewing in the same direction the edge portions of the upper plies together. A sewing machine carrying out the invention includes a presser foot having a sole with a toe shaped front part which engages into each leg portion of the pantyhose to be formed.

Abstract: For a hem stitching operation with a sewing machine having a needle vertically reciprocating and also laterally swingable, a hem stitching presser foot is detachably mounted to a lower end of a presser bar of the sewing machine. The presser foot includes a brush like element which confronts a needle dropping hole formed in a sole of the presser foot, a frictional contact between the needle and the brush like element is produced when the needle passes the outside of the fabric edge, without penetrating the fabric, to stitch a portion of hem stitches on the outside of the fabric edge. The brush like element may be secured to the sole of the presser foot, or alternatively to a fabric guide member for engaging and guiding the fabric edge. The brush may be projected in the fabric feeding direction or across the fabric feeding direction. A pin may be located just beneath the brush like element for constant placement thereof.

Abstract: The present invention is directed to a presser foot attachment adapted for use with a sewing machine for stitching an upper material to a base material and simultaneously trimming the edge of the base material along a line closely adjacent the row of stitches. The presser foot attachment includes a main section and an auxiliary section. The main section of the foot terminates just forward of the sewing machine needle so as to allow the juxtaposed edges of the upper and lower materials to be placed in close proximity to the needle at the onset of the sewing operation. The auxiliary section is movable between two positions and aids in guiding and separating the upper material over the base material and to the sewing station of the machine.

Abstract: A sewing machine with a thread cutting device, a pneumatic/automatic presser foot lifter and an air hose attached to the exhaust of the presser foot lift cylinder or its solenoid valve, the air hose directing the air flow to an air jet tube attached to the presser foot shaft behind the needle by a special holder with a single screw simultaneously holding the presser foot to the presser bar lifter. The presser foot lift cylinder and a solenoid valve connected thereto are mounted as a compact unit on a plate, with a piston of the lifting cylinder operatively disposed adjacent to a lifting angle bracket, the latter being connected to the lifting linkage inside the sewing machine. When the solenoid and lifting cylinder are released to lower the presser foot, the exhaust air from the cylinder is forced through the air jet tube up to its open end held by the holder for blowing the thread end above the presser foot.
