摘要： A bi-directional actuator is disclosed which comprises a frame, rotatable about a principal longitudinal axis. The frame mounts two or more partially spherical drive elements. The centers of the partially spherical elements are located on the longitudinal axis of the frame, and the elements are mounted for rotation about individual axes which are perpendicular to but intersect with the longitudinal axes. The individual axes of the respective drive elements are also angularly oriented with respect to each other. The cross sectional outline of the frame is contained within a cylindrical envelope of less diameter than the spheres. Driving devices, such as a belt, are provided to engage at least one of the drive elements in any rotary position of the frame. Directly opposite the belt or other driving device, the driven element or elements engages a material to be driven, typically a piece of fabric. Rotation of the drive elements by the belt provides for material advancement along a first (longitudinal) axis, rotation of the frame about its own axis serves, through the spherically contoured drive elements, to advance the material along a second axis, at right angles to the first.

摘要： 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. The system provides for automatic centering of the pleats, regardless of minor variations in fabric width, as well as expeditious stitching along the end runs. Operator involvement is limited to loading of the fabric onto the in-feed conveyor and removing the finished article after completion of the pleating operations. A single operator can easily service two machines operating at a relatively high rate of speed.

摘要： The application discloses a method and apparatus for cutting bed sheets and the like from a large, continuous length of fabric, forming hems on the cut edges of the fabric panels, and then sewing the hems. The fabric is fed "wrong side out", and one of the hems is formed upside down while the other is formed right side up. One hem is formed more or less directly above the other. A pair of sewing machines are mounted one above the other, and the entire fabric panel, with the just-formed hem folds, is advanced laterally through the sewing machines, simultaneously sewing both hems. By arranging for the mounting of both sewing machines, one above the other, servicing of the machines by a single operator is readily accomplished. Moreover, the substantial amount of fabric between the two hems is accommodated in a generally vertically oriented loop of the fabric providing for highly efficient utilization of factory space.

摘要： A system and method of fastening a pocket to a portion of a garment is described. Garment working stations are arranged in a preselected manner about a platform with predetermined accurate alignment of their individual garment working operations. Each garment portion is automatically deposited on the platform and aligned with an orientation selected to bring its desired working areas with precision opposite the garment working stations. A garment portion indexer is employed which clamps the panel to preserve its automatically obtained alignment effectively throughout the working operations. The indexer accurately indexes the aligned panel step by step to each of the stations continuously retaining its grip until that is no longer needed. Pockets are deposited on the platform and automatically aligned with a selected indexed panel position. The pocket is attached to the panel at a precisely determined panel location after being transferred thereto with an automatic actuated transfer device. Pocket manipulation is uniquely performed at a garment station to precisely align pocket and panel parts as well as prepare completion of pocket attachment. Aesthetic completion of panel to pocket assembly is obtained with accurate bar tack operations, assuring a repetitively neat product. An automatic panel dart forming station is shown for the attachment of a rear garment panel for a pair of trousers to a back pocket. High speed pocket to garment attachments are obtained.
