Abstract: An electrostatically dissipating shoe protects against building up of electrostatic charges by dissipating of such charges through controlled ohmic path leakage between foot and ground. The shoe outsole is formed of synthetic material of substantial resistivity, providing overall resistance across it of about 10.sup.6 -10.sup.8 ohms. A flexible dissipating strip of synthetic material treated to be slightly conductive (about 10.sup.5 ohm-cm) overlies the outsole and extends along a major portion of the shoe length beneath an insole, being secured to the insole by electrically conductive adhesive. At least a heel portion of the insole is apertured over the strip. A cushion layer and/or sock liner overlies the insole, being also of substantial resistivity (e.g., about 10.sup.5 ohm-cm), and secured by conductive adhesive, which also fills the apertures for providing a conductive path through them to the strip. The construction creates an ohmic path continuous between foot and ground having resistance of 10.sup.

Abstract: A stacker for seizing and successively stacking sewn articles received from a sewing machine. A main support structure has a frame pivotally connected to it and extending upright, carrying a horizontal stacking bar for movement between an article receiving position extending laterally along the sewing table for receiving a sewn article from the sewing machine, and a retracted position spaced outwardly from the table. A clamping bar is carried parallel to the stacking bar by arm members pivotally connected to the frame for movement between an open position spaced from the stacking bar and a clamping position confronting it for gripping the sewn article therebetween.

Abstract: A shoe of the moccasin type is made crush- and deformation-resistant toe by use of a premolded box toe stiffener for stiffening the toe region of the shoe upper. The stiffener is of flexible, resiliently stable character, characteristically remaining in or reverting to its original configuration, including an upstanding flange of curved configuration for lying against and providing securement to the corresponding interior surface of the upper. Principal and side tabs extend rearwardly from the bottom edge of the flange for securement to the sole part of the upper, or to an insole. Exterior foot-opposed surfaces of the stiffener are coated with heat-activated adhesive for adhesive securement to said shoe interior surfaces. The flange has a rear, foot-side inner surface devoid of adhesive, being exposed within the shoe. The method of making the shoe involves thermally forming the stiffener by molding from a blank of heat-formable material.

Abstract: A belt securing means adopted to be used with a belted coats comprising a flexible strip having split arrow head end portions. The flexible strip is inserted into a pair of vertical slots contained in a garment belt and retained therein.

Abstract: A safety shoe having a closed bottom lining is assembled by a method in which a slip last is inserted into a closed bottom lining and a net-fit upper portion is attached to the lining. The forepart of the upper portion is lasted to the lining after a steel toe sub-assembly is fastened to the lining toe portion. An outsole and heel portion are attached to the bottom surface of the upper after the upper and lining are lasted.

Abstract: A thread cutting device for a sewing machine that will cut threads in a scissor-like action. The device is mounted on a sewing machine pressure arm and can be manually operated. The device comprises a stationary horizontal cutting blade; a pivoting cutting blade is attached to the stationary blade so as to form a cutting field and a finger pressure assembly, having a tensioning means, creates a scissor-like action in the cutting field.

Abstract: An apparatus for feeding fabric in a tensionless and distortion free manner to a fabric treating device. The fabric feeding apparatus comprises a loop forming station, a feeding station and an operator-collector station. The loop forming station continuously forms a tensionless loop of fabric by a pair of driven puller rolls, caused to activate by a signal from a photoelectric combination. The loop of fabric is sequentially fed to a feeding station by the controlled movement of a pin clamping assembly. The movement of the pin clamping assembly causes the photoelectric combination to send a signal activating the puller rolls to reform a tensionless loop. This sequence of pin clamping assembly movement and loop formation causes fabric to be continuously fed in a tensionless and distortion free manner to a fabric treating device.

Abstract: Steel ribbons and wires having quenched martensite or bainite microstructure are disclosed having an organic adhesive coating which is degraded at the steel-adhesive interface. The products are useful as steel tire reinforcements.

Abstract: Fabrics having strength despite low bulk density and comprising at least one reinforcing layer of textile-length fibers, at least one layer of short bulk fibers and a bonding agent distributed throughout said fabric layers. Also a process for producing a fabric having a layer of such bulk fibers disposed between two of such reinforcing layers and a process for producing a fabric having a surface layer of such bulk fibers wherein a multi-layered structure containing an interior layer of such short bulk fibers is split along a continuum of lowered bonding agent concentrations at locations predetermined by controlled heating of the structure.

Abstract: The method of autogenously bonding a nonwoven web made from polyamide filaments wherein the filaments contain 0.1 to 20 weight percent of an activating agent and sufficient moisture that the molar ratio of water to activating agent in the filaments is above the bonding limit, wherein the web is heated sufficiently to drive off enough water to reduce the molar ratio of water to agent to a value below the bonding limit and pressed to autogenously bond the filaments in the web. After pressing, the activating agent is desorbed from the web.

Abstract: Fiber forming polyesters are modified by the incorporation in the chain of hydantoin derivatives having polyalkoxylated groups linked to the ring nitrogens. These polyesters exhibit desirable properties such as improved dyeability, thermal oxidative stability, light stability and dyed light fastness.

Abstract: A flexible laminate having a high tear strength comprising an adhesive impregnated open mesh reinforcing web with upper and lower surfaces of lightly bonded fibers, a finish applied to the fiber surfaces, wherein at least one outer layer is adhesively bonded to at least one surface of the web. The fibers in the web are surrounded by adhesive, however the adhesive is prevented from contacting the fibers by the finish, thus allowing the fibers to remain substantially unbonded to the outer layer, thereby permitting substantial freedom of fiber movement within the laminate.

Abstract: Method and apparatus for making a nonwoven fabric wherein a first group of filaments are projected in a longitudinal direction into the nip of a pair of nipped and moving collecting surfaces in such a manner that the filaments fold into and are captured and held by the nip with spans of the filaments lying in the plane of the nip and at the same time projecting a second group of filaments in a longitudinal direction toward one of the collecting surfaces at a location spaced from the nip. The second group of filaments impinges on an impact plate positioned above the collecting surface and is pulled off the impact plate by the moving collecting surface, this causing the filaments in the second group to extend primarily in the machine direction. The moving collecting surfaces carry the groups of filaments into contact with each other to form a nonwoven fabric which is subsequently bonded in a conventional manner to form a finished fabric.
