Abstract
A peripheral re-reeling machine including a first winding roller around which a band-shaped material to be wound is guided; a second winding roller, there being defined between the first and second winding rollers a throat into which winding cores are introduced in succession; a feeder for successively introducing cores into the throat, and control apparatus for bringing about, on each insertion of a new winding core, a variation in the winding conditions for insertion of a new core. A sensor associated with the throat is provided which detects passage of a core at a predetermined point and emits a signal on the passage of the core, with cyclical operational variation in the winding conditions occurring based on the signal.
Claims18
Peripheral re-reeling machine for producing rolls of wound band-shaped material, comprising:
- a first winding roller around which a band-shaped material to be wound is guided;
- a second winding roller, there being defined between said first and said second winding roller a throat into which winding cores are introduced in succession;
- feeder apparatus for introducing the winding cores into said throat;
- and control apparatus for bringing about, at completion of winding of each roll, variation in at least one aspect of winding for controlling advance of a new core through said throat,
- wherein a sensor is associated with said throat, said sensor detecting passage of a core at a predetermined point and emitting a signal upon the passage of said core, with cyclical functional variation of the at least one aspect of winding occurring based on said signal.
Method for producing rolls of band-shaped material wound on winding cores comprising:
- providing a first winding roller around which a band-shaped material is guided;
- providing a second winding roller, a throat being defined between the first and the second winding roller for passage of a winding core;
- upon completion of winding of each roll, varying temporarily at least one aspect of winding to control advancement of a new winding core through said throat,
- wherein passage of said new winding core from a predetermined position is detected and a signal is generated upon said passage, and variation of the at least one aspect of winding occurs based on said signal.
Method for peripheral winding of rolls of web material on winding cores in a winding cradle, wherein a roll of web material is wound on a core in said winding cradle, the roll, upon completion of winding of web material on said roll, is discharged from the winding cradle and a new core is inserted in the winding cradle by temporarily varying at least one aspect of winding, wherein detection of passage of said new core from a predetermined position and provision of variation of said at least one aspect of winding is according to said passage.
A peripheral winding machine, including a winding cradle in which rolls of web material are formed in succession on respective winding cores, and including apparatus for introducing said cores into said cradle, with at least one aspect of winding being cyclically and temporarily varied for introducing a respective new core into said cradle, wherein a sensor is present which detects passage of the core being inserted into said cradle at a predetermined point and emits a signal upon the passage of said core, with variation of the at least one aspect of winding occurring based on said signal.
