1. Device for holding a yarn spool with at least one projecting annular flange, characterised in that the device includes a flat base-plate (A) having a fixed stop (B) projecting outwardly from an upper location of the front face of the base-plate in a slightly downward direction so as to include with the base-plate an angle less than 90 degrees, in that a pivoted spring loaded locking pawl (18) i...

PURPOSE:To prevent aging making a package under winding out of contact by means of a spindle drive winder then winding with specific slow traverse and higher than specific speed thereby reducing distortion caused by the winding position of package. CONSTITUTION:The winding speed must be higher than 5,000m/min where 5,500m/min is preferable, to produce a string having such inner structure as the cr...

PURPOSE:To prevent the inner distortion depending on the winding position and the aging, by providing specific winding thread length and the end face angle to a polyester fiber package having specific thread orientation, tension fluctuation and average differential weight between the central and end portions. CONSTITUTION:In order to release the inner distortion after winding, the crystal orientat...

Method and apparatus for use in building a closed torus tire. An expandable sleeve having an inflatable portion expands to wrap a sheet of tire building material partially about a disintegratable generally toroidal core. A bladder beneath the sleeve is then inflated to roll the sleeve toward the core causing the edges of the sheet to flip or snap from the sleeve surface to the core surface. The ap...

Metallic droplets in liquid, solid or partially solidified form are deposited onto a substrate to produce cast or coated articles by utilizing the Coanda Effect to draw one stream of gas toward another stream of gas flowing over a surface and introducing molten metal between the two gas streams such that the molten flow is broken into droplets. In the embodiment primary fluid flows through slit 50...
