For Folding The Work Patents (Class 112/470.16)
  • Patent number: 8132522
    Abstract: The present invention relates to a method and to a device for processing highly flexural material in strip form. In order to provide a method and a corresponding device for processing highly flexural material 2 in strip form with optimization of working processes and increased production reliability, it is proposed that, in a method for processing highly flexural material 2 in strip form with a first and a second end region 10, 16, in particular of textile belt material 2, the two end regions 10, 16 of the highly flexural material 2 are essentially processed simultaneously, wherein one of the types of processing includes at least one sewing operation. In this case, ensured and consistent quality is achieved with a shortened working cycle time.

  • Publication number: 20040074428
    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.

  • Patent number: 6530335
    Abstract: A sewing device (1) is provided with a programmable electronic control system (4) for sewing folds and tucks. Such that format-dependent parts (guide tongue, pressure pad) can be eliminated at the time of a change of the seam program the use of a guide tongue is eliminated that depends on the form of the seam and of a format-dependent pressure pad. The feed of the fabric is performed only with a folding tool (5) with straight folding edge and the holding and guiding of the fabric during the sewing operation using a straight pressure pad (7). The electronic control system (4) can be programmed such that the desired seam course is obtained exclusively by the superimposition of longitudinal and transverse movements of the pressure pad (7). Parameters (1′-7IV) that determine the seam course are preferably entered in a graphics-supported manner.

  • Publication number: 20020185045
    Abstract: A folding/stitching apparatus (1) includes a sheet setting tray (3) having a slit (7), on which a plurality of superimposed sheets (P1) are set, a folding/stitching plate (16) provided to be freely moved between a standby position for not entering the slit (7) of the sheet setting tray (3) and a folding/stitching position for entering the slit (7) and having a staple bending portion (19) provided in an insertion tip into the slit (7), and a stapler (20) pressed into contact through the sheets (P1) with the folding/stitching plate 16 set in a folding/stitching position to stick staples into the sheets (P1). The folding/stitching plate (16) is moved between the standby position and the folding/stitching position in conjunction with an operation of a handle (12).

  • Patent number: 6401642
    Abstract: A process for folding or folding over pockets with round edge sections is provided along with a device for carrying out the process. Round folding slides (9; 53), provided with concave folding edges (49; 54), are either moved or designed such that their ends (50, 51; 55), either one after another or simultaneously, lead in relation to the middle area of the concave folding edges (49; 54). An especially intense folding effect is thus exerted on the transition areas between the round and straight pocket edge sections and a pocked folded edge that is uniform on all sides is thus obtained.

  • Patent number: 6196147
    Abstract: An apparatus and method are provided for converting a roll of material into various products such as curtains, draperies, valances, or the like. Specifically, the apparatus includes a roll let off for supporting and feeding a roll of material or cloth. After the let off, the edges of the cloth are cut if desired and are engaged by a pair of edge folding and positioning stations for forming vertically folded edges. The folded edges are then converted into hems and sewn into the material by a pair of corresponding hem sewing heads and cloth advancers. Once vertical hems are formed in the cloth, the cloth is cut to predetermined lengths and if desired, folded in a predetermined pattern. The folded pattern can then be transported to a sewing station for further sewing the material into a desired product.
