Abstract: A stranding machine wherein element wires are twisted twice for every turn of the flyer and thus obtained stranded wires are wound on a bobbin positioned inside the flyer in such a manner as to be rotatable thereto. This is an inclined vertical type stranding machine wherein the revolution axis of the flyer is inclined to the vertical line so that the direction of gravity force exerted on the floating frame supporting the bobbin is inclined to the revolution axis of the flyer, which makes it easy to keep the floating frame stationary. This is also a constant Pitch stranding machine provided with a device which control the running speed of stranded wires to keep the ratio of the running speed of stranded wires and twice the revolution rate of the flyer, that is, the pitch of the stranded wires.

Abstract: A metal strip including an elongate web and a pair of longitudinal medial lands on both sides thereof, is successively stamped or coined so as to be provided with a series of coupling elements each including on each of its both sides a transverse projection and a pair of longitudinal teeth one on each side of the projection, the projection being higher than the teeth. The projection and teeth are formed from material of the medial lands and additionally from material of a portion extending all the way around the projection and teeth, which is thinned down to a thickness smaller than that of the web. Then, the metal strip is notched along its marginal edges to provide the outer profile of clamping legs, and is severed into individual coupling elements.

Abstract: A top stop of thermoplastic material is thermally fused onto a plurality of topmost scoops of a continuous coupling element on each stringer tape to limit the upward or fastener closing movement of the slider. The top stop is substantially L-shaped, comprising a longitudinal portion embracing the coupling heads of several topmost scoops and a transverse portion bent outwardly from the upper extremity of the longitudinal portion to secure the stitching thread to the extreme endmost scoop or scoops.

Abstract: An improved thermally and acoustically insulating structure provides both a high average acoustical transmission loss for incoming sounds of particularly low frequency range and a thermally insulating and anti-dewing effects.
