Claims39
A method of forming and doffing a forming package, comprising the steps of:
- (a) positioning a forming tube assembly on a collet of a winder, the assembly comprising:
- (i) an adapter tube which extends over at least a portion of the collet;
- (ii) at least one forming tube extending around at least a portion of the adapter tube;
- and
- (iii) a starter band extending around at least a portion of the adapter tube;
- (b) winding at least one continuous fiber strand around the at least one forming tube to form a forming package;
- and
- (c) simultaneously removing the adapter tube and forming package from the collet.
A method of re-tubing a collet of a winder, comprising the steps of:
- positioning at least one forming tube and a starter band around at least a portion of an adapter tube to form a preassembled forming tube assembly;
- and
- positioning the forming tube assembly over a collet of a winder.
A forming tube assembly comprising:
- an adapter tube configured to extend over at least a portion of a collet of a winder;
- at least one forming tube extending around at least a portion of the adapter tube;
- and
- a starter band extending around at least a portion of the adapter tube.
A forming package assembly comprising:
- an adapter tube;
- at least one forming package extending around at least a portion of the adapter tube;
- and
- a starter band extending around at least a portion of the adapter tube.
A forming tube assembly comprising:
- an adapter tube configured to extend over at least a portion of a collet of a winder;
- at least one forming tube extending around at least a portion of the adapter tube;
- and
- a tube comprising a plurality of annular ribs and extending around at least a portion of the adapter tube.
A forming package assembly comprising:
- an adapter tube;
- at least one forming package extending around at least a portion of the adapter tube;
- and
- a tube comprising a plurality of generally annular ribs and extending around at least a portion of the adapter tube.
A method of forming a forming package, comprising the steps of:
- (a) positioning a forming tube assembly on a collet of a winder, the assembly comprising:
- (i) an adapter tube which extends over at least a portion of the collet;
- and
- (ii) at least one forming tube extending around at least a portion of the adapter tube;
- (b) initially winding at least one continuous strand on a rotating member carried on the adapter tube, the rotating member being separate from the at least one forming tube;
- and
- (c) subsequently winding the at least one continuous fiber strand around the at least one forming tube to form a forming package.
