PURPOSE:To improve operation efficiency by providing a mechanism for temporarily drawing out a winding tube from a transporting medium, and a mechanism for jetting compressed air into the central hole of the drawn-out winding tube to automatically discharge yarn scraps. CONSTITUTION:The first pressure roller 21 and the second pressure rollers 22, 23 are disposed at opposite positions in a triangul...

A method of manufacturing a tire bead ring of the package type by winding metal wires on a form of revolution, the radially inner face of the tire bead ring having a frusto-conical shape of half angle alpha at the apex and of radius R with respect to the axis of rotation of the tire bead ring, in which a permanent circular deformation is effected on the wires prior to their winding on the form of...

(Meth)-acrylic acid esters of the formula in which R1 and R2 are each independently hydrogen, chlorine, fluorine or a C1- to C4-alkyl radical and R3 and R4 are identical or different and represent the group wherein Y is a divalent bridge member from the group and Z is a straight-chain or branched hydrocarbon chain which has 2 to 10 carbon atoms, can optionally co...

PURPOSE:To obtain a compact and simple lens frame structure by dividing the third lens component into positive lens components so that they move independently, and placing a positive lens component having a weak refractive power between the divided lens component and an image surface. CONSTITUTION:The titled lens consists of the first and the third lens components having a positive focal distance,...
