摘要:
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.

The present invention embraces method and apparatus for winding a linear element into a package. Such invention including means for supplying a linear element; a driven rotatable collet having a package collection region and a temporary collection region for the linear element, the collet including a fixed member located in the temporary collection region in a position so it is effective to engage element linearly advanced through the region; interim means for advancing the linear element during times the element is not collected on the collet, the interim means being located in spaced relation with the collet in a position effective to advance the element along a path that brings the element into contact with the collet in the temporary collection region so that the fixed member can engage the element during rotation of the collet to begin collection of the element on the collet and to effect severance of the element between the collet and the interim means; and means for moving the element from collection in the temporary collection region to the package collection region of the collet for package formation.

The present invention embraces a method and apparatus for collecting linear material on wound packages including the steps of supplying linear material, rotating a first collet having a package collection region and a temporary package collection region, winding the linear material on the collection region of the first collet, rotating a second collet having a package collection region and a temporary collection region the second collet including a fixed member for engaging linear material during transfer of such material from the first to the second collet, laterally moving the advancing material along the first collet from the package collection region to the temporary collection region, contacting the linear material advancing to the first collet with the second rotating collet in the temporary collection region to engage the linear material on the member to move the linear material with it and thereby to begin collection of the material in the temporary collection region of the second collet to sever the material between the collets and laterally moving the material along the second collet from the temporary collection region to the collection region to begin package formation.

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.
摘要:
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.

The disclosure embraces a method of and apparatus for simultaneously winding linear bundles of filaments, such as strands of glass filaments, in a filament-forming operation into two or more packages on a driven rotatable collet and the linear bundles or strands traversed by guide members axially of the packages, the progressively increasing sizes of the packages normally intermittently moving the traverse guide members away from the packages, and wherein an undersized package activates an instrumentality, indication or signal warning the operator of such condition and interrupting movement of the traverse means away from the packages.
摘要:
The disclosure embraces a method of and apparatus for producing a roving package of strands of attenuated glass fibers or filaments, the method and apparatus involving segregating the fibers or filaments into bundles or strands in spaced relation and the bundles or strands wound into a package with the bundles or strands advanced toward the package in a plane substantially normal to the longitudinal axis of the package whereby the individual bundles or strands engage the package at peripherally spaced surface regions and are collected in side-by-side or waywound relation.

A method and means for superimposing a secondary, higher frequency, lower amplitude oscillation of the angle of the trajectory of a glass fiber relative to a forming surface upon a primary, lower frequency, higher amplitude oscillation of the release mechanism.
摘要:
A glass fiber bulk strand roving that is made up of a multiplicity of strands, each of which is made up of a plurality of individual fibers, for example, 200 of such fibers. Each strand of the roving has a multiplicity of rather long, axially extending loops, for example, axially extending loops with a calculated length of at least 6 inches, and a multiplicity of shorter, unbroken, cross-axially extending loops that are formed in the axially extending loops of such strands. The axially extending loops and the cross-axially extending loops interengage and intertwine with one another to form a composite entangled structure. The roving of the present invention is made by a process that uses a finger wheel to form axially extending loops in strands and a spinner downstream of the finger wheel. The looped strands from the finger wheel pass through a relatively unrestricted passage in the spinner which imparts a twist to such a looped strands, and then through a relatively restricted outlet orifice that is downstream of the outlet of the spinner. A back-up or puddling of the looped strands occurs in the spinner near the outlet thereof, due to the axial length of the loops in the strands and the restriction in the outlet of the spinner in the form of the outlet orifice, and this back-up or puddling of the looped strands in the spinner, in conjunction with the spinning thereof, results in the formation of the cross-axial loops in the axial loops of the strands.
