Abstract
In a bobbin revolver, comprising bobbin-carrying chucks mounted on a carrier head which is rotatable to move them successively into a winding position where they receive synthetic filament, a lace-up arm is provided to hold filament in a suitable disposition during lacing up of the revolver so that the filament can be taken up automatically by a chuck moving into the winding position.
Claims15
A winding machine comprising
- a rotatable carrier head having a longitudinal axis;
- a plurality of chucks rotatably mounted on said carrier head and disposed in parallel on said carrier head for rotary movement between a winding position and a doffing position, each chuck having filament take-up means for catching at least one filament presented thereto and being adapted to removably mount a bobbin thereon for receiving a filament thereon in said winding position;
- filament infeed means for passing filament to a bobbin carried on a chuck in said winding position and such that in normal operation a take-up length of filament extending between said filament infeed means and a chuck moving from said winding position is presented to a second chuck moving to said winding position in a menner enabling the take-up length to be taken up on said take-up means on said second chuck, and
- lace-up means movable, during lacing of the machine prior to normal operation thereof, from a position outside the working zone of the machine to a position inside said zone to hold at least one filament between said lace-up means and said filament infeed means so that the length of filament extending between said lace-up means and said infeed means can be taken up by a chuck moving to said winding position.
A bobbin revolver comprising
- a rotatable carrier head having a longitudinal axis;
- a pair of chucks rotatably mounted on said carrier head and disposed in parallel on opposite sides of said longitudinal axis of said carrier head for rotary movement between a winding position and a doffing position;
- a pair of bobbins, each said bobbin being removably mounted on a respective chuck to receive a filament thereon in said winding position;
- infeed means for feeding at least one filament to said winding position;
- a filament take-up means on each chuck for catching at least one filament presented thereto;
- and
- lace-up means for holding thereon at least one filament extending between said infeed means and said lace-up means, said lace-up means being movable into a holding position to dispose the legnth of filament between said infeed means and said lace-up means along a given line across the path of movement of a respective chuck between said doffing position and said winding position whereby a chuck moving from said doffing position into said winding position receives the filament held on said lace-up means with a predetermined angle of wrap corresponding to a length of filament extending between said infeed means and a full package on a chuck moving from said winding position to said doffing position.
A winding machine comprising:
- a carrier head rotatable about an axis;
- a plurality of chucks mounted on said carrier head to successively move into and out of a winding position upon rotation of said carrier head about said axis, each said chuck being rotatable about a respective chuck axis thereof to receive and hold a bobbin thereon for rotation therewith, each said chuck including a filament take-up means for catching at least one filament presented thereto;
- filament infeed means for passing a filament to a bobbin on a respective chuck in said winding position;
- and
- a lace-up means for holding at least one filament passing from said infeed means, said lace-up means being pivotal into a lacing position to hold the filament along a line between said infeed means and said lace-up means to present the filament to said take-up means on a respective chuck during movement of said respective chuck into said winding position.
A winding machine comprising
- a carrier head rotatable about an axis;
- a plurality of chucks mounted on said carrier head to successively move into and out of a winding position upon rotation of said carrier head about said axis, each said chuck being rotatable about a respective chuck axis thereof to receive and hold a bobbin thereon for rotation therewith, each said chuck including a filament take-up means for catching at least one filament presented thereto;
- filament infeed means for passing a filament to a bobbin on a respective chuck in said winding position;
- and
- a lace-up means for holding at least one filament passing from said infeed means, said lace-up means being locatable in a lacing position prior to normal operation of said machine to hold the filament along a line between said infeed means and said lace-up means to present the filament to said take-up means on a respective chuck during movement of said respective chuck into said winding position, said line corresponding to a line which can be adopted in said normal operation by a length of filament between said infeed means and a chuck moving from said winding position.
A method of lacing-up a winding machine having a rotatable carrier head, a plurality of chucks mounted on the carrier head to successively move into and out of a winding position upon rotation of said carrier head, each chuck including a filament take-up means for catching at least one filament presented thereto, and filament infeed means for passing a filament to a respective chuck in said winding position, said method comprising the steps of
- holding a filament passing from the filament infeed means at an intermediate point thereof in a position corresponding to a point in a path of a filament fed from the infeed means to a chuck moving from said winding position during normal operation;
- and
- moving a respective chuck into said winding position while holding the filament at said position to engage the filament take-up means of said respective chuck with the filament between the infeed means and said position.
