Abstract

An apparatus for winding strand of glass fiber filaments is disclosed. The apparatus comprises at least one takeup collet on which a strand of glass fiber filaments is wound, a guiding mechanism for guiding an end portion of the strand which has started being drawn off from a spinning bushing to a predetermined position below the spinning bushing on a stream of a water, and an auxiliary winder mechanism rotatable for catching and winding the guided end portion of the strand. The auxiliary winder being moved toward said takeup collet when the end portion of the strand is under a condition capable of being transferred onto the takeup collet for bringing the strand into contact with the takeup collet within a winding zone of the takeup collet. An associated method therefor is also disclosed.

Claims18

Dependent claims

A method of winding a strand of glass fiber filaments on a takeup collet, comprising the steps of:

(a) guiding an end portion of the strand being drawn off from the spinning bushing, on a stream of fluid, to a strand pulling mechanism;
(b) automatically engaging said guided strand with said strand pulling mechanism and pulling the strand therewith;
(c) automatically moving an auxiliary winding mechanism from a standby position to a winding position, and moving said pulled strand into winding engagement with said auxiliary winding mechanism and winding said strand on said auxiliary winding mechanism;
(d) automatically moving said strand from said auxiliary winding mechanism into winding engagement with an empty takeup collet and winding said strand on said takeup collet and moving said auxiliary winding mechanism back to said standby position;
(e) winding said strand on said takeup collet until a predetermined amount of said strand is wound on said takeup collet to fill said takeup collet;
(f) automatically moving said auxiliary winding mechanism from said standby position to said winding position, and moving said strand into winding engagement with said auxiliary winding mechanism and winding said strand on said auxiliary winding mechanism;
(g) automatically moving said auxiliary winding mechanism back to said standby position, while continuing to wind said strand thereon;
(h) replacing said filled takeup collet with an empty takeup collect;
(i) automatically moving said auxiliary winding mechanism from said standby position to said winding position, while continuing to wind said strand thereon;
repeating steps (d)-(i) sequentially until said strand accidentally breaks and then repeating steps (a)-(i).

7 more elements

An apparatus for winding a strand of glass fiber filaments comprising:

pulling means for drawing a strand of glass fibers from a spinning bushing;
fluid guide means for automatically guiding an end portion of a strand of glass fibers on a stream of fluid into engagement with said pulling means;
takeup collet means, having a winding axis, for winding said strand of glass fiber filaments on a bobbin disposed coaxially on said winding axis, said takeup collet means including replacement means for replacing a filled bobbin with an empty bobbin;
auxiliary winding means, coaxially movable along said winding axis between a standby position and a winding position, for windingly receiving said drawn strand from said pulling mechanism, when in said winding position, transferring said strand to and from said bobbin when in said winding position, and continuously winding said strand, when retracted to said standby position, during replacement of the filled bobbin by an empty bobbin;
means for coaxially moving and auxiliary winding means between said standby position and said winding position.
