Abstract: A carriage for carrying a labeller, bundler or similar tool for working on sheet material spread on a supporting table is moveable vertically and transversely relative to such table by an associated lifting and transport cart allowing the carriage to be lifted from one table and transported to another table at which it is lowered onto the new table to bring it into working relationship therewith. The carriage may be engaged by the cart from the side or end of the table. Accordingly, the carriage may be moved from one table to another even in cases where the carriage can not be easily moved onto or off of the end of a table because of such table end being inaccessible. Means hold the carriage against vertical and lateral movement relative to the table while the carriage is in working relationship therewith, and these means are moveable to disengaged positions to free the carriage for vertical movement relative to the table when removing the carriage from or placing it onto the table.

Abstract: For the production of circular seams with overlapped ends on a workpiece, a sewing machine driven in a controlled manner and provided with a marker for applying a mark, and a sensor for detecting the mark after marking the workpiece with a mark. The workpiece is sewn until the mark is effectively detected by the sensor which is disposed in a predetermined relationship to the marker, and thus initiates a control operation which initiates the end of the sewing operation in dependence upon a particular number of oversewn stitches. The mark may be applied and detected on the work material in one operating cycle. Thus, for example, circular workpiece openings may be sewn in such a way that the seam end is matched to the start of the seam in spite of different diameters of the work piece opening.

Abstract: Method and apparatus for automatically providing notching indicia on the edge of a garment subassembly to provide a dimensional reference to be utilized in subsequent fabrication of the goods. A conveyor transports the garment subassembly to a notching station at which the pre-assembled parts are secured in accurate registration to the path of a notching device that is movable on a carriage toward and away from the notching station. The notching device includes a vertically extending notching blade having a recessed cutting edge which, when positioned at the notching station, overlies an edge of the garment part subassembly. On displacing the blade downward, the notch indicia is cut into the garment piece after which the notching unit is withdrawn to a home position while the notched part is transported by the conveyor to a subsequent fabrication step. In a preferred embodiment two notching devices supported in a common path on opposite sides of the notching station are utilized.

Abstract: Pattern printed textile products, such as pillow cases and items of apparel, are produced in such a manner that the pattern is always properly positioned on the final product. The pattern is printed on a fabric web while it moves in a first direction, and in synchronization with the pattern printing a magnetic mark is disposed (e.g. jet printed) on the web in a known position adjacent the pattern in the direction of fabric movement. A number of marks may be printed, which define the perimeter portions of the fabric if cut into fabric panels. Subsequently, the magnetic marking on the fabric is detected, the fabric is stopped, and rough cut is made at a known position with respect to the mark. A fine cut later severs the mark from the rest of the fabric. Automatic hemming can take place during fine cutting, and after fine cutting and hemming, other steps are performed to turn the fabric into a final textile product.

The first conveyor device intermittently draws lengths of the strip corresponding to the cut lengths of the fitted elastic bedsheets from a supply. A cutting device is provided at the end of the first conveyor device. At a right angle to first conveyor device is arranged a second device for the pieces of cloth which are cut by cutting device from strip of cloth.

Abstract: Method and apparatus for determining and regulating the amount of advance of a plurality of workpiece plies at a sewing machine which is affected by scanning the individual plies while recording the stitches being formed between two separate feed points and actuating top and bottom feed devices to achieve a desirable feed of each ply. Signs present or to be applied at any desired point of the workpiece plies are scanned at two successive points, and pulses generated by a pulse generator connected with the main shaft of the machine are summed during this period of time. The pulse sum is compared with a number of pulses which depends on the mutual spacing of the scanning points and on the adjusted stitch length. For two work plies the pulse sums formed between the recognition of the signs are compared directly. As signs to be scanned are used either imprinted marks, the jags of a pinked workpiece edge, or the bright, dark structure of a surface section of the workpiece.

Abstract: French pleated draperies of any selected length are manufactured by serging panels of fabric together to provide a wide section of material. After hemming the bottom and serging a strip of buckram to the top of the section, the upper and lower edges of the section then are positioned on a pleat marking table. Ultraviolet markings then are made on the fabric to produce invisible marks at the locations of the centers of the pleats to be formed and also to indicate where fan folds should be formed at the bottom of the drapery. After a desired width of the section has been pleat marked, that width is cut from the section of material. After sewing the side hems, pleats are formed using a conventional pneumatic pleat forming machine by illuminating each ultraviolet sensitive pleat center mark with a center blade of the pleat forming machine and then forming that pleat. The pleat then is sewn by two pleat sewing machines.

Abstract: An auxiliary needle is supported by a shiftable and rotatable slide rod which extends in a slightly inclined position relative to the vertical and is guided by an extension in a guide slot. The upper portion of the guide slot extends at an angle relative to the slide rod. Therefore, if moved from its rest position downwardly into its working position, the auxiliary needle performs first a combined rotary and translational motion, and then, upon penetrating a workpiece, only a straight longitudinal motion.

Abstract: A web of fabric material is fed flat along a substantially horizontal table. The web is continuous and is marked and then partly cut just short of its edges while in the feeding plane. The edges of the web are then gripped, moved together, and overlapped as the web is moving, and the edges are sewn. A moving gripper pulls the web through the apparatus to an off the arm sewing machine, and a puller roll downstream of the sewing machine assists pulling of the web and maintains the seam tensioned during sewing.

Abstract: A sewing machine for sewing workpieces, comprises a stationary bottom part with an arm which has one end pivotally mounted on the bottom part and an opposite end overlying the bottom part.

A revolving looper is mounted on the end of the opposite arm and it has a thread exit opening and a needle is mounted for upward and downward movement in the bottom part for cooperation with the looper. The workpiece is clamped between the base part and the arm and the needle traverses the workpiece upwardly. The construction includes a looper thread guide member mounted on the opposite arm adjacent the looper and has a thread deflector located between the needle path and the thread exit opening of the looper and extending above the point of stitch formation directly laterally of the needle path crosswise to the axis of the looper.

Abstract: Herein disclosed is a method of and an apparatus for marking a woven fabric with indicia of discrete events of a predetermined nature or natures such as unit lengths of the fabric woven and the occurrences of defects in weaving such as improperly inserted picks of weft yarn, wherein picks of an index yarn or yarns are inserted into the weft-filling shed of the warp yarns concurrently with insertion of picks of the weft yarn when the occurrences of events of the predetermined nature or natures are detected during weaving of the fabric, the natures of the events being distinguished from one another by the difference between the lengths, colors, numbers or any other characteristics of the picks of the index yarn inwoven into the fabric.

Abstract: The disclosure is directed to a method and means for detecting a skipped stitch, in the absence of a thread break, on a chain stitch sewing machine or the like. The detector system includes a secondary thread tension system which functions to provide lateral pressure against an unbroken thread in the region between the primary thread tension means and the sewing needle. Whenever, during the course of the sewing operation, there occurs a momentary malfunction in the chain stitch operation, a momentary variation in tension in the unbroken thread occurs in the region between the needle and the primary tension device. This momentary reduction in tension enables a yieldable member to momentarily displace or deflect the thread. The sensing device detects such momentary deflection of the thread and initiates an appropriate control function.

Abstract: A workpiece prepuncturing device for use with a sewing machine having drive means for reciprocating a needle and means for feeding a workpiece into association with the needle to sew a stitch comprises a perforating tool which is located at a spaced location from the needle which is comparable to a multiple of the stitch length. The perforating tool cooperates with a counter tool which is mounted on the opposite side of the workpiece and is movable toward and away from the workpiece in timed relationship to the speed of the feed and the reciprocation of the perforating tool. The counter tool is supported in a base portion of the sewing machine by an elastic suspension, and it is in drive connection with the main shaft of the machine which operates the needle and the feed for the workpiece.
