A process for winding of a material web, comprising:

• forming a first nip between a movable pressing drum and a first reel, said first reel being rotatably mounted on a secondary transport device, and said secondary transport device defining at least a main winding position;
• moving said material web through said first nip;
• winding said material web about said first reel to form a first winding roll;
• controlling a line force between said moveable pressing drum and said second reel by shifting said moveable pressing drum;
• moving said secondary transport device to open said first nip such that said material web runs freely from said pressing drum to said winding roll;
• rotating a second reel at a speed corresponding to a speed of movement of said material web;
• forming a second nip at a location other than the main winding position by moving said second reel via a primary transport device into contact with said pressing drum, such that said material web is interposed therebetween;
• cutting said material web so that the web can thereafter be wound onto said second reel;
• winding said material web onto said second reel to form a second winding roll;
• and
• transferring said second reel to the main winding position on said secondary transport device for continued winding.

A process for winding of a material web, comprising:

• forming a first nip between a movable pressing drum and a first reel such that the first nip is formed by relative movement of a first reel with respect to said pressing drum, said first reel being rotatably mounted on a secondary transport device, and said secondary transport device defining at least a main winding position;
• moving said material web through said first nip;
• winding said material web about said first reel to form a first winding roll;
• moving said secondary transport device to open said first nip such that said material web runs freely from said pressing drum to said winding roll;
• rotating a second reel at a speed corresponding to a speed of movement of said material web;
• forming a second nip at a location other than the main winding position by moving said second reel via a primary transport device into contact with said pressing drum, such that said material web is interposed therebetween;
• cutting said material web to define a new web beginning;
• winding the new web beginning said material web onto said second reel to form a second winding roll;
• and
• transferring said second reel to the main winding position on said secondary transport device for continued winding,
• wherein during the opening of said first nip, said pressing drum moves with said first winding roll until said pressing drum reaches a stop, and wherein during said moving, said second reel forces said pressing drum away from said stop.

• a second reel mounted on a primary transport device for guiding the second reel along a primary transport path, said primary transport device being moveable between at least a second nip position and the main winding position;
• and
• a stroke device for controllably moving said secondary transport device which is controlled as a function of an increase in relative diameter of one of said first and second reels,
• wherein at least said second nip position and said main winding position are each defined by contact between said second reel and the pressing drum, with said material web interposed therebetween;
• wherein a second nip is formed at said second nip position prior to said second reel moving to said main winding position, such that the material web is guided over a portion of the circumference of said second reel;
• and
• wherein said stroke device is controlled independently of a line force acting between said pressing drum and one of said first and second reels.
