Abstract: Two or more warp-knitted members of a tubular or cylindrical shape are interconnected by a connecting thread to provide reinforcement to be inserted longitudinally in a row of helically coiled fastener elements. The tubular warp-knitted members may be wrapped around core members. A choice is available of diameters of the warp-knitted members so as to be compatible with the particular shapes and contours of given fastener elements. A plurality of warp-knitted members are interconnected in such a fashion that the resulting reinforcement can be adapted for securing a relatively large-size fastener element onto the tape.

Abstract: A slider aligning device is disclosed for use in a separable slide fastener of the class comprising a pair of stringers having longitudinal rows of interfitting fastener elements on their opposed edges respectively, and a pair of sliders arranged reversely to each other on the rows of fastener elements for longitudinal movement therealong to engage and disengage the same. The aligning device includes a pair of recesses formed inconspicuously at the contracted end of one of the sliders, and a pair of tongues formed correspondingly at the opposed contracted end of the other slider. The tongues are so shaped and sized as to fit neatly in the respective recesses when the contracted ends of the two sliders are brought into contact with each other, so that the sliders can be held in correct alignment during insertion or removal of a pin member at one end of one of the stringers into or out of the guide channels of the respective sliders.

Abstract: A pair of top stop members of a synthetic resin are integrally united with several topmost scoops of respective continuous coupling elements of a slide fastener so as to cover at least the head portions of the scoops. In order to prevent deformation of the stop members as a result of forced contact with each other at the end of the fastener closing movement of a slider one of the stop members is made shorter than the other stop member. Thus, when the slider is moved to a topmost position on the rows of coupling elements, the scoop positioned immediately under the lower end of the shorter stop member abuts against the longer stop member, while the stop members themselves are held out of contact with each other.

Abstract: In a dual sash window assembly having a pair of overlapping sashes mounted within an outer frame for relative horizontal movement, the outer frame has a stepped sill, with a pair of parallel spaced rails formed thereon as upward extensions from the risers of two of the steps. Mounted on the respective rails for rolling movement therealong, the sashes have bottom horizontal frame members carrying weathertight sealing strips arranged to make sliding engagement with the exterior surfaces of the respective risers of the sill. The sealing strips serve to make the window perfectly weathertight in spite of the presence of dust outlets formed by cutting away parts of the rails.

Abstract: In the operation of punching a performed stop blank onto a pair of coupled fastener stringers placed over a stationary die, a sensor is provided which moves up and down over the die to sense mechanically the presence of any foreign matter such as the operator's fingers between the punch and die. The punch is permitted to descend fully onto the stringers on the die only after the sensor has completed its downward stroke. In the apparatus of the invention the up-and-down motion of the punch is effected as by an air cylinder via a lever, and the sensor is coupled to another lever which is spring loaded to follow the motion of the punch lever, in such a manner that the sensor travels faster than the punch. Limit switches are employed to prevent the full descent of the punch where necessary.

Abstract: A net jointing structure is provided for separably jointing or coupling a pair of nets together. The structure has a pair of elongate net strips each having first and second longitudinal opposite edges and having a mesh size progressively smaller toward the second edge, the first edge being formed integrally or adapted for connection with one end of each of the nets. A sliding clasp fastener includes a pair of stringers each having on and along one longitudinal edge a row of interlocking elements and secured at the other longitudinal edge to the second edge of the elongate net strip, and a slider slidably mounted on the rows of interlocking elements for coupling and uncoupling the pair of stringers.

Abstract: Aluminum or aluminum alloy is first anodized to form an oxide film thereon.
