Abstract
Method and apparatus for advancing continuous glass strand during times the strand is not being collected into a package by a winder. A pair of cooperating rolls having a plurality of helical teeth are rotated to advance the strand therebetween.
Claims8
In an apparatus for advancing continuous glass strand wherein a winder collects the strand into a wound package, wherein a pair of rotatable rolls cooperate to advance the strand therebetween during times the strand is not collected on the winder and wherein at least one of the rolls is rotatably driven, the improvement comprising:
- a plurality of helical teeth extending outwardly from each of the rolls adapted to concurrently advance the strand from the rolls and move the strand laterally between the rolls.
Apparatus for advancing continuous glass strand comprising:
- a winder for collecting the strand as a wound package;
- and
- interim means for advancing the strand during times the winder is not collecting the strand, the interim means comprising a pair of cooperating rotatable rolls, at least one of the rolls being driven, each of the rolls having about sixteen helical teeth extending from the outer surface thereof and adapted to advance the strand positioned therebetween, the helical teeth of each roll being at a negative angle of about 30.degree. from the axis of rotation of the roll.
A method for advancing continuous glass strand comprising:
- introducing the strand between a pair of cooperating rotatable rolls, the rolls having a plurality of helical teeth;
- and
- rotating said rolls to concurrently advance the strand from the rolls and move the strand laterally between the rolls to a guide means.
