Abstract: A handicraft clip is provided for forming a pleat in a cloth. The clip includes a relatively wide base plate and a narrower fastening plate connected to the base plate via a connecting hinge portion having a reduced thickness for allowing pivotal movement of the fastening plate relative to the base plate. The base plate is formed with a generally elliptical through-hole, while the fastening plate is provided with a locking protrusion to be fitted into the through-hole of the base plate when the base plate and the fastening plate are superposed on each other. The fastening plate includes a cloth holding portion of a generally constant width. The cloth holding portion is formed with a slit for insertion of a cloth. The slit extends from the distal end of the cloth holding portion toward the locking protrusion.

Abstract: A tucking attachment for a sewing machine having a tucking blade with one end positioned adjacent material and a tucking blade drive with an output shaft mechanically coupled to the tucking blade. A control, connected to the tucking blade drive, is operable to command displacement to form a tuck in the material adjacent a presser foot of the sewing machine. Thereafter, the sewing machine is operated to sew a number of stitches in the tuck, and the tucking blade is then retracted. Repeating the above cycle of operation permits successive tucks of different lengths to be formed in the material.

Abstract: An apparatus for forming fabrics for use, by way of example, in coverings for architectural openings includes a system for handling single or multi-layered fabrics by suspending the fabric from a lift tower, threading the fabric through various clamp systems within a housing for the apparatus, and subsequently forming horizontal rows of hobbles, tunnels, and/or attached rings by gripping and releasing the fabric with a vacuum clamp, upper and lower clamps, and a tucker blade clamp while a reciprocating tucker blade forms horizontal tucks in the fabric. Hobbles can also be formed in one layer of the fabric through use of the vacuum clamp which gathers a portion of one layer of the fabric while the other layer is handled differently. In doing so, hobbles are formed between tucks in the fabric with the hobbles establishing a fabric resembling a Roman shade.

The tucks are selectively treated by forming a tunnel or attaching guide rings. Hobbles can also be formed in one layer of the fabric through use of the vacuum clamp which gathers a portion of one layer of the fabric while the other layer is handled differently. In doing so, hobbles are formed between tucks in the fabric with the hobbles establishing a fabric resembling a Roman shade.

Abstract: A tucking attachment for a sewing machine having a tucking blade with one end positioned adjacent material and a tucking blade drive with an output shaft mechanically coupled to the tucking blade. A control, connected to the tucking blade drive, is operable to command the tucking blade drive to move the tucking blade through a programmable displacement to form a tuck in the material adjacent a presser foot of the sewing machine. Thereafter, the sewing machine is operated to sew a number of stitches in the tuck, and the tucking blade is then retracted. Repeating the above cycle of operation permits successive tucks of different lengths to be formed in the material.

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 method and system using an apparatus for folding and sewing a pleat in a material without the need for manual folding. The method includes the use of clamps to hold the material in place and the movement of pleates to fold the material. The pleat is kept in place by a clamp during stitching. The method may be used on any type of pleating operation, but is particularly applicable to the formation of pleats in yoke-back panel material assemblies.

Abstract: A method for the production of decorative fabrics having flat narrow fabrics stitchingly secured in a longitudinally compressed convoluted condition to a substrate or devoid of a substrate. The narrow fabrics are such as lace, ribbon, braid or tape. The narrow fabric is guided into the path of a conventional reciprocating sewing needle whereby the needle on each downward stroke strikes the narrow fabric and advances it in a compressed convoluted condition toward the needle plate whereupon the fabric is attached in its compressed convoluted condition.

Abstract: A pin tucking device for forming a plurality of pleats-like folds on a fabric has a flat base plate for fixing guide plates in position in cooperation with guide-plate mounting plates. One of the guide-plate mounting plates which is mounted on the base end-side of the base plate has kerfs spaced wider from one another than those of the other guide-plate mounting plate which is mounted on the front end side, so that it is possible to effectively cope with any change in needle intervals in the pin tuck sewing machine by hook portions of the guide plates being brought into engagement with the kerfs. Further, by engaging and disengaging the guide plates relative to the guide-plate mounting plates through such engagment and disengagement of the hook portions it is possible to vary the number of guide plates and thus to change the intervals of pleats-like folds in various different ways.

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 guide board for use in guiding fabric in a pin-tucking sewing machine in which the guide members are made freely detachable and replaceable to obtain a desired pattern of pin-tucking without changing the guide board but simply removing and/or replacing the guide members.

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.
