  • Patent number: 5256238
    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.

  • Patent number: 5188047
    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.

  • Patent number: 4833953
    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.

  • Patent number: 4785750
    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.

  • Patent number: 4658741
    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.

  • Patent number: 4599958
    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.

  • Patent number: 4102283
    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.
