A moving strand is provided and a size is applied to the strand. A collet is rotated to wind the strand and build a package. The strand is reciprocated with a strand reciprocator to lay the strand in a pattern on the package surface as the package rotates. The strand reciprocator is lubricated with a lubricant which is compatible with the size. There is also provided an apparatus for winding a fiber strand to build a cylindrical strand package having a radially outer surface. The apparatus includes a rotatable collet for receiving the strand to build a package. A strand reciprocator is mounted to guide the strand from edge to edge of the package and to lay the strand in a helical pattern on the package surface as the package rotates. A lubricator for atomizing a lubricant creates a fog of small airborne lubrication particles which are compatible with the size. A lubricant supply manifold is connected to the lubricator for transferring the small airborne particles to predetermined lubrication locations at the winder. These lubrication locations include the cam surface and the grooves provided thereon, the cam bearings and the roller bail bearings.

Method and apparatus for lubricating continuous fiber strand winding

An apparatus is provided for forming a cylindrical package of wound strand having a radially outer surface with first and second edges and a central portion therebetween. The apparatus includes a rotatable collet for receiving the strand and winding the strand to build a package. A guide is mounted for reciprocation from edge to edge of the package to lay the strand in a helical pattern on the package surface as the package rotates. A roller bail mounted for contacting the surface as the package is being built for holding the strand in place on the package. The roller bail is divided into separate rollers with each roller contacting the package surface at one of the edges and not contacting the package surface at the central portion.

Apparatus for producing square edged forming packages from a continuous

A self supporting, helically wound package of yarn suitable for being payed out by withdrawing the yarn without collapse of the package is disclosed. The yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape. The package has edge portions positioned axially at the ends of the package, and the flat spots are positioned in the edge portions of the package.

Self-supporting yarn package

A strand of individual filaments has a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape. The primary cross-sectional shape preferably has an aspect ratio within the range of from about 1:1 to about 6:1, and the flat cross-sectional shape preferably has an aspect ratio greater than about 6:1., with the period of the periodic flat spots being within the range of from about 0.2 to about 6 meters.

Zero twist yarn having periodic flat spots

A package winder for a plurality of multiple-filament strands or bundles includes a fixed strand shoe for forming strands, a movable strand shoe for separating the strands into an array of distinctly spaced and oriented bundles and a strand array guide which reciprocates along an axis parallel to the axis of a rotating collet. The guide includes an obliquiely oriented slot which maintains the arrangement of the strands of filaments as they are wound onto the collet. A pair of obliquely oriented parallel guide pins are disposed proximate the transverse limits of the reciprocating guide. The pins engage one or more of the strands, limiting the axial width of the package and greatly improving the edges of the package. The movable strand shoe, strand array guide and pins may be utilized in pairs to produce a pair of packages on a single elongated collet.

Reciprocating strand guide for split strand roving packages

Composite panels each having a casing and insulating material in the casing are mounted in a covering layer over the inside of a supporting structure by mechanical fastening means. Joint cover members including insulating material and outer facing material are disposed in the spaces between casings of adjacent composite panels. The outer facing material is sealed to front panel portions of the casings to form a primary barrier for cryogenic liquids therewith. An additional secondary barrier may be provided by using composite panels with interior panels in the casings sealed to inner sides thereof and dividing the casings into front and rear compartments, each having insulation therein, and using front and rear joint cover members, the outer facing material of the rear joint cover members being sealed to outer sides of the casings of adjacent composite panels to form a secondary barrier with the interior panels of the composite panels.
