Abstract: An automatic curtain pleat sewing apparatus for forming and sewing pleats for a curtain, comprising: a sewing machine having sewing needles; a pleat forming-supplying unit having forepart holding plates for holding the leading end portion of the curtain fabric and the remainder thereof; pleat folding plates for pleating the curtain fabric thus held by the forepart holding plates; a pleat portion supply unit for integrally rotating the forepart holding plates and the pleat folding plates so as to insert the pleated portion of the curtain fabric in the sewing part of the sewing machine; a rear-end holding unit capable of moving the rear end portion of the curtain fabric forward and backward while holding the rear end portion thereof; and a full-width measuring unit capable of measuring the full width of the curtain fabric when the rear-end holding unit moves backward.

Abstract: A ruffling device adapted for mounting on a sewing machine, includes: a base for attachment to a presser bar of the sewing machine, a pivotal lever mounted on the base connected to a needle bar of the sewing machine, so that the pivotal lever may be reciprocally pivoted as a needle-bar is vertically reciprocally moved; a work folding lever for folding a work fabric and movable in forward and rearward directions with respect to a feeding direction of the work fabric for a sewing operation, a motion conversion mechanism for converting the pivotal movement of the pivotal lever into the forward and rearward movement of the work folding lever, so that the work folding lever cooperates with a presser foot mounted on the base for forming a ruffle on the work fabric, a timing adjusting device for adjusting an operation timing of the work folding lever, and a stroke adjusting device for adjusting a stroke of movement of the work folding lever.

Abstract: A removable ruffler for a sewing machine is removably mounted on the sewing machine by way of an exclusive removable holder of the sewing machine. A body of the ruffler for carrying out ruffling of a cloth has a ruffling member, a holder guide rail, and a presser foot guide rail, each extending in a transverse direction. A presser foot is mounted on the presser foot guide rail for sliding movement thereby pressing the cloth downward. A presser foot holder adjusts relative position of the presser foot and the body of the removable ruffler. The presser foot holder has longitudinal position adjustment portion abutting on the presser foot. The longitudinal position adjustment portion has an opening vertically formed therein and having a large longitudinal width. The presser foot holder also has a transverse position adjustment portion fitted on the holder guide rail.

Abstract: A high speed sewing machine (15) ruffler (16) where the sewing machine output (26, 27) drives a belt (28) which operates a pair of shafts (24, 25) to move a ruffler pusher blade (46) at high speeds. The sewing machine output belt causes shaft (24) to oscillate by a drive lever (35), and causes shaft (25) to rotate by means of drive pulley (29). The oscillating shaft (24) rocks ruffler arm (45) to cause pusher blade (46) to move to and fro, while rotating shaft (25) causes an eccentrically mounted lift link (47), through connector (51), to lift the pusher blade from the material (53) upon the withdrawal stroke and to lower the pusher blade upon the feed stroke.

Abstract: An automatic tuck forming apparatus includes a mechanism folding a piece of fabric and an improved clamp having a longitudinally and forwardly extending member for grasping the fabric and for moving the fabric along a stitching axis. The clamp also defines a downwardly projecting element on the forward portion thereof and a channel which is disposed on the stitching axis so that the needle of a sewing machine can pass therethrough during the stitching of the fabric.

Abstract: The disclosure is directed to method and apparatus for automatically forming and sewing pleats in draperies and the like. Conveyor feeding of the fabric margin is provided for. A rotatable indexing drum, with a plurality of pleating stations, engages the fabric in successive spaced area and forms the desired pleats. A displacement element acts on the fabric between pleat-forming stations of the drum for uniform, controllably variable pleat spacing. The formed pleats, while gripped by the pleat-forming drum, are advanced to a sewing station, where the sewing machine and a related fabric clamp function as manipulating jaws to engage and remove the pleat, which is thereafter held by the clamp while the pleat is stitched. A unique form of clamp allows the sewing machine to be in continuous motion during the stitching operation, while the fabric is held substantially stationary.

Abstract: A shirring attachment includes a rotatable feed wheel 51 positioned over a stripper blade 60 and normally positioned in spaced relationship above the work surface of and in front of the sewing needle 45 of a sewing machine. A first ply of material 78 is extended over the work surface and beneath the stripper blade to the feed dogs 68 of the sewing machine, and a second ply of material 80 is extended over the stripper blade to the sewing needle. The rotatable feed wheel is driven with a peripheral velocity that corresponds to the speed of the sewing machine motor, usually at a higher velocity that the feed dogs, and the feed wheel is moved by an air-actuated cylinder 54 at the command of the machine operator down toward the stripper blade into engagement with the upper ply of material so as to feed the upper ply of material to the sewing needle at a faster rate than the movement of the lower ply of material.

Abstract: An automatic unit for the programmable tucking in of part of a piece of material and the automatic fixing of this tuck by a heat-sealed reinforcement comprises two machines arranged at an angle of 150.degree. relative to one another and symmetrical with respect to the median axis separating them.

Abstract: A sewing machine attachment for automatically accomplishing a ruffling function is disclosed. Ruffling is performed by a finger means which is positioned to grip a fabric disposed on the work table of the sewing machine when the finger means is advanced toward the needle of the machine. Power for the ruffling operation is coupled by a rotatably mounted member to which the finger means is rotatably secured at a point removed from the axis of rotation of the member. In this manner the finger means is given a reciprocating ruffling motion.The apparatus of the present invention is extremely advantageous inasmuch as it minimizes the number and weight of reciprocating parts. It is thus able to move efficiently and reliably at high speeds.

Abstract: An apparatus for forming triple type of tucks in a curtain cloth is disclosed. The apparatus comprises on a base frame a first sewing machine with a first presser, a second sewing machine with a second presser, a movable base plate arranged for movement in the transverse direction of the cloth, and a stationary base plate arranged adjacent the second sewing machine. Further, a pair of upper and lower keep plates, a pair of upper and lower expansion spatulas, and a width setting spatula are mounted on the movable base plate for movement in the lengthwise direction of the cloth, and extend therefrom over a face plate. A double tucking plate with two sheet metals extends from the stationary base plate over the face plate.

Abstract: A pleating machine for automatically forming pleated drapes from blank drapery panels. The pleating machine is comprised of six stations which cooperate automatically under the control of a controller. The pleating machine is comprised of a loading station, a loop-forming station, an overhead transfer assembly, a corner sewing station, at least one pleat and sewing station and at least one ejection assembly. After a drapery panel is loaded in the pleating machine, the machine automatically forms a header in the panel, determines the spacing required to form pleats uniformly across the panel just loaded and forms uniformly spaced single loops along the header. Thereafter, the corners of the header are sewn, and the entire panel is transferred to the pleat and sewing station, where each loop is formed into a pleat and sewn. After the last pleat is sewn the entire panel is ejected.
