Abstract
A filament winding apparatus comprising an arm pivotable to traverse a filament guide longitudinally of a mandrel, the guide being pivotally mounted on the arm, and the pivotal motions of the arm and guide being derived from a common rotatable member with a phase difference such that the guide is maintained in advance of the arm in the direction of travel of the latter.
Claims8
A filament winding apparatus comprising:
- a mandrel mounting for receiving a mandrel on which an article is to be wound and for rotating a received mandrel about an axis thereof;
- an arm;
- a pivot mounting for the arm;
- a filament guide carried on the arm for pivotal movement relative to the arm about an axis extending longitudinally thereof;
- a member arranged to be driven in rotation about an axis;
- a first drive transmission connecting said member to said arm to cause the arm to pivot on its pivot mounting and thereby to cause the filament guide to move generally longitudinally of a mandrel on said mandrel mounting;
- and a further drive transmission connecting the member and the filament guide to pivot the guide relative to the arm with a predetermined phase difference relative to the pivot motion of the arm such as to maintain the guide in a position in advance of the arm in the direction of travel of the latter.
