Abstract
A method of cooling a material web includes, after drying a material web, moving the material web in a given direction on a meander-shaped web path over a cooling cylinder and at least one other cylinder disposed at a location selected from a group thereof consisting of a location upline and a location downline from the cooling cylinder, as viewed in the given direction of the web path, providing for the moving of the material web to be with at least partial looping thereof over the cooling cylinder and the other cylinder, and arranging the cylinders with respect to one another so as to exclude contact pressure with one another that is in effect between two respective ones of the cylinders; a device for performing the method.
Claims32
A method of cooling a material web, which comprises:
- moving the material web in a given direction over a cooling cylinder and at least one other cylinder disposed at a location selected from the group consisting of a location upline and a location downline from the cooling cylinder, as viewed in the given direction of the web path;
- carrying out the step of moving of the material web with looping sections of the material web passing over the cylinders, the looping sections being connected for moving the material web along the looping sections at least approximately on a web path being meander-shaped, always curved or non-rectilinear;
- and
- arranging the cylinders with respect to one another so as to exclude contact pressure with one another between respective two of the cylinders.
A device for cooling a material web comprising:
- a cooling cylinder around which the material web movable on a web path is partly looped;
- and
- another cylinder disposed at a location selected from the group consisting of downline from and upline from the cooling cylinder;
- the material web having looping sections passing over said cylinders, the looping sections being connected for moving the material web along the looping sections at least approximately on a web path being meander-shaped, always curved or non-rectilinear.
A cooling-cylinder stand, comprising:
- a device for cooling a material web including:
- a cooling cylinder around which the material web movable on a web path is partly looped;
- and
- another cylinder disposed at a location selected from the group consisting of downline from and upline from the cooling cylinder;
- the material web having looping sections passing over said cylinders, the looping sections being connected for moving the material web along the looping sections at least approximately on a web path being meander-shaped, always curved or non-rectilinear.
A web-fed rotary printing press, including a device for cooling a material web, the cooling device comprising:
- a cooling cylinder around which the material web movable on a web path is partly looped;
- and
- another cylinder disposed at a location selected from the group consisting of downline from and upline from the cooling cylinder;
- the material web having looping sections passing over said cylinders, the looping sections being connected for moving the material web along the looping sections at least approximately on a web path being meander-shaped, always curved or non-rectilinear.
