A glass fiber-forming feeder having a bottom wall having a network of internal passageways interconnecting the field of orifices extending therethrough, and a method for producing such bottom walls is disclosed.

Method and apparatus for forming glass fibers

A method of and apparatus for controlling the breakage of glass fibers comprising: feeding a supply of molten glass through an orificed wall to form glass streams; attenuating the glass streams to form a plurality of glass fibers; gathering the glass fibers into glass strands; forming the glass strands into a wound package; determining when a break has occurred in the fibers; determining the location of such break; and positioning a stream of fluid at the orificed wall at the location of the break to inhibit further breakage of fibers that are adjacent to the location of the break.

Method of and apparatus for controlling the breakage of glass fibers

The invention disclosed herein relates to method and apparatus for forming glass fibers wherein a fiber forming feeder has a bottom wall comprised of a substrate and a control layer arranged to form reticulated indentations around the orifices therein to promote the movement of molten glass from a disrupted orifice to an adjoining orifice wherein attenuation is continuing.

Apparatus and method of producing glass fibers employing a tipped or tipless annular bushing plate from which fibers are drawn as an annular array. A cooling gas, such as air, is directed into contact with the bushing plate and with either, or both, the exterior and interior of the annular array.

Annular bushing for forming glass fibers

The present invention embraces apparatus and methods of forming mineral fibers, such as glass. Such invention comprising a mineral fiber forming bushing bottom wall comprising a plurality of tubular members attached together at adjacent sides to form a rigid structure adapted for flow of molten mineral material through the tubular members to form a layer of molten mineral material along the undersurface of the tubular members and rod members projecting below the undersurface of the tubular members. The rod members are attached to the tubular members and are adapted for flow thereon of the molten mineral material from the undersurface of the tubular members for attenuation into fibers.

Apparatus and method for production of mineral fibers

The present invention embraces an apparatus for, and methods of, forming mineral fibers, such as glass. Such invention comprising a mineral fiber forming bushing bottom wall comprising a base plate and elongated members projecting downwardly from the exterior undersurface of the base plate. The base plate is of a porous material such as a sintered, foamed or fusion bonded material to form a rigid structure adapted for flow of molten mineral material therethrough to form a layer of molten mineral material along the exterior undersurface thereof. The rod members are adapted for flow thereon of the molten mineral material from the flooded exterior undersurface for attenuation into mineral fibers.

The invention relates to method and apparatus for finishing a plate having projections extending therefrom comprising reinforcing the projections of the plate with a material which can be removed without damage to the projections, cutting the projections to desired length, and removing the material.

Method for finishing a plate

Method and apparatus for introducing a first strand into a continuously moving second strand are provided by positioning the first strand in spaced relation along the length of the continuously advancing second strand, and laterally moving the first strand to engage the continuously moving second strand such that the first strand is continuously advanced with the second strand.

Strand splicing apparatus

A feeder is provided for supplying molten mineral material in the form of streams. The feeder comprises a bottom wall member, two side wall members and two end region members, each comprising an end wall portion and portions extending from the end wall portion on three sides thereof to form a bottom wall portion and two side wall portions, the bottom wall member and the side wall members being affixed to the bottom wall portion and the side wall portions, respectively.

Stream feeder apparatus

A strand collecting apparatus and method of the type in which the strand is split into bundles and advanced by, and wound onto, a rotating collet is disclosed. The strand is traversed linearly of the axis of rotation of the collet by the rotation of a rotating strand traverse. The strand traverse is oscillated in a direction parallel to the axis of rotation of the collet, and a strand splitter oscillates in phase with the strand traverse to guide the strand into engagement with the strand traverse.

Strand collecting apparatus and method

Method and apparatus for introducing a strand into a continuously

A method and apparatus for the entanglement of a first strand and a moving second strand are disclosed. A member having a passageway therethrough for the passage of the second strand is adapted for the circumferential positioning of the first strand. Means are provided for repositioning the first strand from the member into circumferential entanglement with the second strand by reducing the circumference of the member.

Entanglement of a first strand with a second strand

The present invention embraces a winder for collection of linear material into a wound package. The winder comprises a driven rotatable collet upon which linear material is collected as a package in a package collection region. The collet includes a temporary collection region adjacent the collection region. The collet has in the temporary collection region a circumferential surface region and a member having at least a portion extending generally axially of the collet in spaced apart relation outwardly of the circumferential surface region and terminating to define an opening to a space between the outwardly disposed portion of the member and the circumferential surface region so that during rotation of the collet prior to package formation linear material extending along a path disposed in generally crossing relationship to the axis of rotation of the collet can be moved laterally of the path in a direction axially of the collet along its circumferential surface through the opening into the space between the circumferential surface region and the outwardly disposed portion of the member for catching engagement by the member to move the linear material with it and thereby to begin temporary collection of the linear material in the temporary collection region prior to package formation.

Apparatus for packaging linear material

The present invention embraces a method and apparatus for simultaneously winding two linear elements into strand packages. The invention includes; means for supplying a first linear element and a second linear element; a first rotatable collet having a package collection region and a temporary collection region, the first collet including a fixed member located in the temporary collection region in a position so it is effective to engage the first element linearly advanced through the region; a second rotatable collet having a package collection region and a temporary collection region, the second collet including a fixed member located in the temporary collection region in a position so it is effective to engage the second element linearly advanced through the region, the collets being in spaced apart, side by side parallel relationship below the element supply means; means for rotating the collets; a single interim means for simultaneously advancing both linear elements during times the elements are not collected on the collets, the single interim means being located in spaced relation with the collets in a position effective to simultaneously advance both the linear elements along individual paths that advance each of them over its respective collet in the temporary collection region so that the fixed member in its respective temporary collection region can engage the linear element during rotation of its collet to begin collection of each linear element on its respective collet and to effect severance of each linear element between its respective collet in the interim means; and means for moving the elements from collection in their respective temporary collection regions to their respective package collection regions for package formation.
