Abstract: This invention relates to a dual clamping system for a sewing machine. The dual clamp system comprises a first clamp and a second clamp which may be used to clamp a first workpiece and a second workpiece, respectively, at a sewing station of the sewing machine. The first and second clamps are preferably of different shapes and dimensions so that different shaped workpieces can be clamped at the sewing station. In the preferred embodiment, the first and second clamps are adjustable inner clamps for clamping an inner portion of the first and second workpieces, respectively. The dual clamping system also comprises a peripheral clamp for clamping at least a portion of the periphery of either or both of the first and second workpieces at the sewing station. The dual clamping system permits an operator to either separately or simultaneously clamp and sew a plurality of workpieces having the same or different shapes.

Abstract: A counter-weighted eccentric or crank is clamped to an end of the upper drive shaft. A link is pivoted between the eccentric and an end of a short leg on a V-shaped rocker. The base of the V-shaped rocker is pivoted on a fixed pin. The long arm of the V-shaped rocker is connected to a needle bar to drive the needle bar up and down. The movement of the needle bar carries a main needle and thread through a workpiece to make stitches in the cloth.

Abstract: A tangential drive needle bar shifter for tufting machines. The tangential drive needle bar shifter includes a computer system for creating and storing selected carpet patterns and for controlling the operation of at least one motor which drives the needle bar. The motor includes an output shaft which rotates through a selected degree of rotation in a selected direction. At least one belt is driven by the rotation of the shaft to create lateral displacement of an engagement device is secured thereto. Displacement of the engagement device ultimately creates a shift of the needle bar. As the motor is actuated, the needle bar is shifted a distance proportional to the degree of rotation of the output shaft. A position locking mechanism, or indexer, is provided for preventing the needle bar from shifting farther then required and thus preventing the needles from colliding with the corresponding hooks.

Abstract: The disclosed stitching machine and method orients cooperating needle and hook components of a sewing machine in spaced horizontal alignment, and suspends flexible sheet(s) to be stitched in a generally vertical orientation between these sewing machine components, and tensions the sheet(s) to a flat stitchable condition whereby the sewing machine components might stitch interior seams through the flexible sheet(s). Horizontal and vertical slides support the cooperating sewing machine components to move along horizontal and vertical axes parallel to the suspended flexible sheet(s), and controlled drives shift them in unison along these axes as needed to trace out an intended seam pattern relative to the flexible sheet(s). A conveyor is provided with a substantially vertical run of a height in excess of the sheet(s) to be stitched when vertically oriented, to pass the sheets between the sewing machine components and hold them in the vertical orientation for stitching, and to remove them after being stitched.

Abstract: An improved method and apparatus for the assembly of pillow-top mattress covers. In the method of this invention, the gussets for a pillow-top mattress cover are prepared in a single step in which the gusset material is folded longitudinally, and the flange material is attached thereto and the gusset material is sewn together in one stitch. Thereafter, a gusset is attached to each of the top and bottom panels of the cover along its outer edge. Each gusset is secured to the underside of its associated top or bottom panel at the folded edge using a blind stitch which is not visible externally of the panel. No gluing is required. During the step of attaching the gusset to its associated mattress cover panel, precisely positioned mitered corners are formed on the gusset where the gusset is to be attached to the corner of its associated panel.

The punch tool also has a cylindrically-shaped distal end connected to the proximal end.

Abstract: A double cam drive operates on a main drive shaft of a buttonhole sewing machine is disclosed. Three double cams are arranged sequentially on the main drive shaft. A first double cam operates a looper mechanism, a second double cam drives a feeder, and a third double cam drives a needle bar mount for operating a bite mechanism to deflect a needle housing to make side stitches and tacks. Each double cam has a cam collar and two generally-circular concentric cams. Each cam of a double cam is positioned off-center on the cam collar with one cam positioned opposite the other. The three double cams have mounted collars at axial ends for securing the double cams to the shaft. Spacers are positioned between any two adjacent double cams for creating the proper spacing between the cams. A follower plate is pivoted on a stub shaft and has two rollers. The first roller contacts an outer surface of the first double cam and the second roller contacts an outside surface of the second double cam.

Abstract: An impact-resistant garment comprises closed rings (2) joined together to form a layer (1) protecting against impacts inside the garment. Elongate filling elements (3) of limited flexibility are threaded through the rings (2) to prevent the penetration of spike-shaped objects through the rings (2).

Abstract: An apparatus is provided for orienting flaccid material such as hose blanks having toe ends and bulkier welt ends while they are being conveyed from a supply point to a receiving point to ensure that blanks arriving at the receiving point are received, for example, toe end first. The apparatus includes first and second suction conduits in communication with an outlet. The first conduit has an inlet to which hose blanks are successively presented. An orientation determining mechanism senses which end of a blank enters the inlet. If a toe end is sensed, the hose is permitted to travel unhindered to the outlet. If, however, a welt end is sensed at the inlet, suction is created in the second conduit, and the welt end is temporarily drawn into the second conduit. While the welt end is thus located, suction in the first conduit causes the toe end to be drawn therealong, past the second conduit and toward the outlet.

Abstract: A system and method for controlling the stopping point of a tufting machine in relation to a preset stitch pattern. The system includes a controller and an encoder to detect the current location of a tufting machine needle bar in the stitch pattern. Upon receipt of a stop signal, the controller insures that the needle bar is stopped at a preset stop step in the stitch pattern. In a preferred embodiment of the invention, the controller first slows the main drive shaft of the tufting machine to a jogging speed prior to stopping the tufting machine, and stops the machine at the home position of the carpet pattern. Introducing a delay between receipt of the stop signal and deceleration of the main drive shaft minimizes the jogging time of the machine. The method is directed to stopping the tufting machine at a predetermined stop step and at a position relative to degrees of mainshaft rotation.

Abstract: The sewing apparatus of the invention is applied, for example, in sewing of a tape-form circular rib to the end portion of a tubular cloth such as the waist portion of briefs. A cutter 19 disposed in front of the needle drop point 5 of the sewing machine cuts the tubular cloth C along the direction matching with the cloth feed direction. A cloth end correcting device guides the end portion of the set tubular cloth C in a direction crossing the cutting line of the cutter 19. A cloth end detector 26 detects the end portion of the tubular cloth C at a first position on the cutting line parallel to the cloth feed direction passing through the cutter 19 and a second position remote from the cutting line in a direction crossing the cloth feed direction.
