Abstract
A multi-carrying-roll winder, and method for winding a material web with a multi-carrying-roll winder. The multi-carrying-roll winder comprises a first carrying roll, a second carrying roll, a loading device, and a controller. The first and second carrying rolls contact a reel upon which a material web is to be wound, such that the first carrying roll is driven to wind the material web onto the reel. An additional loading device contacts a circumference of the reel to additionally drive the reel. A controller adjusts an amount of driving power applied to the reel by each of the first carrying roll, the second carrying roll and the additional loading device.
Claims26
A multi-carrying roll winder, comprising
- a winding bed in which a winding reel is located, said winding bed comprising:
- a first driven carrying roll;
- a second driven carrying roll;
- and
- an additional drive device, having an outer elastic coating, that acts on a circumference of said winding reel to drive said winding reel;
- wherein said additional drive is initially powered by a majority of total driving power applied to the winding reel, and, as the diameter of the winding reel increases, the driving power of said first and second carrying rolls increases to a majority of the total driving power applied to the winding reel, whereby the driving power of said additional drive decreases to a minority of the total driving power.

A multi-carrying roll winder, comprising:
- a first carrying roll, said first carrying roll contacting a reel upon which a material web is to be wound, said first carrying roll being driven to wind the material web onto the reel;
- a second carrying roll, said second carrying roll contacting the reel, said second roll being driven to wind the material web onto the reel;
- a loading device, having an outer elastic coating, that contacts a circumference of the reel to drive the reel;
- and
- a controller that adjusts an amount of driving power applied to the reel by each of said first carrying roll said second carrying roll and said loading device;
- wherein said additional drive is initially powered by a majority of total driving power applied to the winding reel, and, as the diameter of the winding reel increases, the driving power of said first and second carrying rolls increases to a majority of the total driving power applied to the winding reel, whereby the driving power of said additional drive decreases to a minority of the total driving power.

- and
- an additional drive device that acts on a circumference of said winding reel to drive said winding reel;
- wherein said first and second driven carrying roll and additional drive device can be controlled independently of one another;
- wherein said additional drive device applies a driving power of at least approximately 15%, of total driving power, to the winding reel at a start of a winding operation;
- wherein an amount of driving power applied to said winding reel by said second driven carrying roll is greater than said amount of driving power applied to said winding reel by said first driven carrying roll during at least a predefined section of a winding operation;
- wherein said amount of driving power applied to said winding reel by said additional drive device decreases and said amount of driving power applied to said winding reel by said first driven carrying roll increases when a diameter of said winding roll reaches a predefined diameter.
